Molly Tuttle Concert @ Ogden Was Excellent ~ MT GR8 As Ever; Touring Band Is Tighter, Has Complete Arrangements Throughout The Set, And Is Even Choreographed 25Oct25

I was solo to the Molly Tuttle concert @ Ogden Theater on Saturday. The Highway Knows Tour concert was excellent and the sound was good at the Ogden from the 2nd riser above the mosh pit, center stage. Molly Tuttle was exceptional, as I now come to expect... she is a guitar playing goddess, and a fine songwriter. She opened the show just as she does the latest album, with 'Everything Burns,' but she played a wild double necked 12 string & guitar someone had gifted her. That song uses her searing 12 string riffs from the opening. So good.

I wasn't on the rail for this show, unexpectedly, as traffic all the way from COS to the theater was bad. Doors were already open on my arrival at 7:15pm, which is late for me. It wasn't a big issue but with two lead -in artists and a 100min set from Molly, it was a long time standing. Opening the show was a shy but sweet sounding kid from around Nashville: Cecilia Castleman. Decent songs, sweet voice, capable guitar (which she liked to mod to a variety of sounds). Later in the show Molly invited her back to sing Goodby Little Miss Sunshine with her.

2nd up was a seasoned and funny Texas country singer named Joshua Ray Walker. His voice was special, his demeanor & schtick humorous, and his playing was excellent. Texas country for sure... there were plenty of folks near me that came to see him vs Molly Tuttle. Some even left after Walker... they sang along to his raucous and irreverent tunes. He was good and again was invited out by Molly for a duet later in her set.

Back to Molly Tuttle and the band... I saw this group debut in Vail in early June this year and, as expected, they've been working hard on all aspects of the show ~ so much tighter. The Ogden delivery was much improved with great touring arrangements of Molly's songs and covers, good solos from around the band, and even keen and a little campy choreographed moments during the show. The whole thing was excellent beginning to end. Beyond Molly's playing anything strummed, picked, or hammered (guitar, 12 sting guitar, electric, banjo, etc) and singing lead, the new band includes great musicians: Mary Mulroney upfront on fiddle, mandolin, keys, and backing vocals, Vanessa McGowan, also up front on bass, double acoustic bass, and backing vocals, Megan Jane on drums and other percussion (like washboard), and Ellen Angelico on lead electric, pedal steel, and dobro. This is a now a spectacular lineup alongside MT... different from Golden Highway (and seemingly as yet unnamed) but no less fun to see and hear. That said, I come to hear the bandleader ~ and she is killing it. Many of the songs for this show were from the latest album or her fav covers but there was bluegrass stuff and even older, like 'Take The Journey.' I like the claw-hammer songs best like this and 'Rosalee' & 'That's Gonna Leave A Mark' from her recent album. Harmonies with Molly from the front women were pretty good, especially on the single mic setup she used for the duets with opening act artists as well.

As usual, later in the show, timed with 'Old Me (New Wig),'Molly stripped off the wig and displayed her long now bald head from alopecia. I have friends who've had it and Molly still does ~ crowd was supportive, and she continued to shred. No selfie and no marquis shot ~ I was late but in plenty of time to enjoy another MT concert from this impressive and impossibly hard-working signer-songwriter and bandleader. 

Quick Outing On The Ark Tailwaters ~ Couple Of Bigs & Some Smalls On Gorgeous Day 20Oct25

I headed solo on a nice Monday to the PT @ NC to fish. It's been a while and it was fun; I toted the RF True 5 loaded with a nymph rig. Flows were up over several days to ~300cfs, skies were clear, water was turbid and off with 3ft viz. The best performer was oddly a #22 rainbow warrior dropper (good for visibility I guess), but the MHFBPT worked too, as did the oil can Perdigon weight. I saw precious little bug sign but for a small & brief mayfly hatch @ 11am; it did not bring anybody up. Not many pics as I mostly forgot but one 20" cutbow was near and far to net 3 times before landing. I also saw a stork on the holes too, twice... on approach he moved on further upstream. Not epic and fishing was searching, not targeting, but not bad.

'I'm With Her' Concert @ Paramount ~ Fabulous Show & VIP Experience 15Oct25

Jim & Mary, Bob & Byron, and Kala & I went to the 'I'm With Her' concert in Denver with my urging. We bought VIP tickets and sat in the orchestra center row 7 for the show. As noted before, the Paramount is gorgeous and the sound is superior. Good thing, as these women are great artists and the vocals were among the best I've ever heard ~ their accompaniment was madly skilled strings across the board.

Our VIP experience included a row 1 close up 3 song set with audience Q&A before the show and a signed poster and lanyard badge. We arrived right on time and the pre-show was cool. These are spectacular artists who are completely down to earth... honest and engaged the entire intimate pre-event. 'I'm With Her' are Sara Watkins (fiddle, uke, vocals), Aoife O'Donovan (guitar, vocals), and Sara Jarosz (guitar, octavia, mandolin, banjo, vocals). All are strong alt-bluegrass and Americana/Roots solo artists in their own rights and formed this very special supergroup in 2014.

We exited the theater after the pre-show, walked in the rebuilt 16th St mall, and had really good Italian dinners nearby at Panzini (thx Jim). Our timing was again perfect (always easier with assigned seats) as with VIP we skipped the line and headed right into the theater; we arrived to our seats with 1 minute to spare before Jon Muq took the stage. Jon had a sweet voice and seemingly relevant songs but he was hard to hear, especially on dialogue. I was worried sound was going to be rough in row 7 but it was only odd on his set. Jon's a Ugandan immigrant who headed to Austin, TX.

We got up and walked around a bit after Muq; our seats were mightily cramped both shoulder width wise as well as (no) legroom wise. The front 28 rows at the Paramount were temporary reserved seating for 'I'm With Her,' often they are SRO mosh pit... the temporary nature allowed a bad install for our seats. This was the only downside to the outing. Again, 'I'm With Her' harmonies, blends, and answers are just spectacular: Watkins' soprano rocks big; O'Donovan's folk builds great structure for the tunes; Jarosz's round tone is beautiful. I have both of the albums and knew all the songs ~ hard to imagine, but they were just as good, maybe better, live. One of the best shows ever.

The team separated on departure but the COS-bound team got the Paramount marquis selfie at the end.

 

Fall On The Deck ~ Peregrine Gathers For Wine & Nosh 14Oct25

The clouds parted for one of the finest deck vibes we've loved during our Rocky Mtn fall '25. A doz wine  aficionados descended for 'Fall on the Deck.' Fortunately nobody did. 

Wilke Sighting In COS ~ WooHoo: Salmon & Albarino, Meuller St Pk, Paravacini's, Games, And Urban Egg 10Oct25-12Oct25

Whoa, a Wilke sighting was made in Colorado Springs! Our friends visited for a weekend of fun and we did have same. On arrival we enjoyed debate, a cheese plate, and some bottles of Edgar's Albarino with a nice salmon & roasties dinner from Kala. We arose to pumpkin bread smells and left early enough for Meuller St Pk to hike. We chose a multi-ridge, multi-view hike on a decent but cool fall day and caught the last vestiges of aspen color on the Front Range. See the team finish strong with Wilks still actively debating the state of the world with Kala.

On the way back we hit the cool kite fluff install over a pond in Green Mtn Falls ~ nice but amazingly crowded on these waning day of early light. Not much wind but still cool. We hit a fav Italian spot, Paravacini's, for dining. Super tasty and my wine choice was keen even though Franco wasn't there to tap the cellar.

We arrived safe back at Blodgett and enjoyed some games, as we do. Boys won Joker Jumper on a comeback and Dave & Les completely dominated in dominos. The next AM we spun the 'hood in the FlyBox at pace. Common thread ~ me as a teammate; heh heh. We also did Urban Egg for breakfast beneath Pikes Peak, which had no fog hat today; good wrap on a GR8 WE with our buddies. 

A Ride, A Rip, Some Rock, And Rations ~ Alliterate Front Range Events 02Oct25-07Oct25

Kala and I have been in alt locations but today we got to ride bikes downtown again. Great weather and a nice ride...

I caught up again with Matt and his mates for a rip around the Mount Evans/Blue Sky area. We didn't have to do much leaf peeper leaping despite the timing. It was still pretty. I rocked on back out to Summit and stopped at ORB to conclude.

Jim & I hit Red Rocks on my way back to COS for a concert at Red Rocks. As often, I was there to see the opening act of three, Jade Bird. She delivered a good 45min show with hits sung of challenging life moments. She's back to a strong one woman show after a keen stint as front-woman with her ex in a full band. Both are great. Sound at RR as always, was excellent.

We also saw Saint Motel (my first time), who were good. Jazzy band with solid lead vocals and fervent fans singing all the songs ~ mostly shouting the many chorus lines. I didn't stay for the headliners, Young The Giant, I've seen them before and wanted to get home and sated; Jim said they were good.

Kala took me to a restaurant she enjoyed earlier ~ but we couldn't find it. Yet, we had a nice evening at 503 West where Korean-inspired food was very good, but the tap list was wanting.

Building New Speakers With Tang Band W4-1337SDF Drivers - TABAQ vs DCR 01Oct25

Update 31Oct25 ~ Nest GR8 Room Audio Upgrade... I moved the new Peregrine TABAQs to the Nest GR8 Room. Here they are, still unfinished, in the room in a good location against the oblique corners flanking the monitor, and raised a foot. I measured in pure direct stereo, both with and without the BDS correction circuit, and the improved location really obviated the need for correction IMO. I rebalanced/re-EQed the system, using Denon's internal DSP, for 5.1 surround for cinema (Dolby D/PLII) and music (DTX Neo 6). Such a great upgrade from the NHT mains. Definitely time to spin up a double bass reflex for the center channel now.

Tang Band W4-1337SDF drivers... I have some keen "leftover" Tang Band full range 4" titanium W4-1337SDF drivers. They were strong potentials, and tested, in the FrugalHorn FH3s during a bake off. I liked them and kept them but they lost in that cabinet to the Mark Audio Pluvias. I also have a spare sheet of 12mm Baltic birch plywood. So, I decided to build some new speakers with the leftovers. I wanted to employ some new acoustical physics ideas and started out on paper & computer. I compared a quarter-wave transmission line design to a double chamber bass reflex design in mathematical models. Here's the driver spec...

DRC TABAQ... A mass loaded (the air in the speaker and port) QWTL design by Bjorn Johannessen for an alternative Tang Band 3" driver was modeled in King's MathCad software; it's called the TABAQ (Tang Band Quarter-wave) and has been proven by DIYers and commercial builders/sellers. I 'built' something similar (in hornresp) to fit my 4" driver well and accommodate its Thiele-Small parameters. The Qts of the driver is on the edge of effective for this kind of speaker, at .34, but it is super efficient at 89dB. I futzed plenty with King's math too but needed to find an alternative to MathCad first (which only works on Windoze)... that never panned out well enough on macOS or Linux.

A MLQWTL cabinet design accentuates some bass (below the driver's resonant frequency) by delivering an in-phase lower frequency (a quarter-wave) from the rear throw of a full range driver, through a tuned port. The entire 'line' of the speaker from closed end to port exit is a vital dimension to get a quarter wave 'exactly' and the port dimensions are key for tuning that low frequency. I've done a design prior including a taper along the line (which helps with resonances), but not a forward firing rectangular port cabinet with a straight line (stuffing will be important). Here is the hornresp modeling of my TABAQ with (horn) section dimensions, 80gr of polyfill into 2/3 of the 'line,' and the acoustic power response (just look at the low end and ignore the bumps; else will ultimately be smoother). I should get ~1/2 octave at least below 70Hz out the port, or 50Hz. The modeling shows higher but I think I'll do better; hopefully I can even get to 45Hz.

DCR (Double Chamber Reflex)... A double chamber reflex (or dual reflex) speaker cabinet employs two separate but connected chambers each ported to the outside for accentuated bass response. Such a design performs similarly to a straight bass reflex cabinet except that distortion can likely be reduced (and perhaps size too) by its being more efficient in using the throw length of the driver over two resonant frequencies. Since the TB W4-1337SDF has a somewhat short Xmax of 2.5mm (I know there is no standard measure but relative to other TBs, it's short), I figured improved efficiency might work well in such a cabinet. Such designs have been implemented by DIYers from designs like the Cordelia from Scott and Bandit from Roman, and Claudio Negro's work. DCR cabinets can be smaller and the overall port length (which for some tunings can be too great to be a straightforward fit) is distributed throughout the cabinet in smaller pieces. Here is the Bandit, a tuned DCR for a Tang Band 4" driver not unlike my leftover.

Modeling again was done using hornresp. A standard vented (bass reflex box) for this driver would be ~ 4L and would get down to 70Hz basically.

A DCR box would be a bit larger and deliver the same but smoother bass. I don't know why port 1 looks longer in the diagram; it is correct and equivalent to the others in the parameter settings. The response of this cabinet may be too weird at 170Hz. I didn't model deadening the smaller chamber, which'd help.

Decision Time... I'm gonna start by building the MLQWTL, a pair of TABAQs. It just appeals to me a little more and will likely have better low end performance. If I have sufficient scrap materials from the 12mm and the other 15mm and 18mm scraps I have, I might also built the DCR and compare them.

Building My 'Peregrine' TABAQ... I headed to Summit (where my tabled power tools reside) and followed my simple cut sheet. The TABAQ is a very straightforward project with straight cuts and butt joints; stuff was sliced up and ready to assemble in <75min. The only modestly tricky part was putting a 101mm diameter hole in a 110mm wide front baffle. Bjorn never eased the back of the front driver hole and with just 12mm plywood, I didn't either. A Peregrine falcon, found frequently above my ridgeline in COS, is small but can fly downward faster than terminal velocity ~ like my light tower TABAQ loaded with the W4-1337, it slays unsuspecting prey. 

The build continued through the day but with less sawdust in the PM. I added some no-impedance poly-holders at 2/3 of the line length. I installed the binding posts (found some nice cheap ones for just $10/4pcs). I weighed out 80g of poly for each speaker. 

They are done but for the sanding and staining. They sounded best to me when propped up a smidge in front as they are pretty short with the drivers well below ear level when listening seated. Overall they are very impressive with plenty of bass without a sub and great mid to highs. I did get the bump at 45Hz for which I hoped. I could use a baffle step loss correction circuit; the baffle is very small. The SPL sweep shows this and is a little wobbly. I will work that with room placement ultimately. I could use DSP as an alternative to either the BSL or other defects.

Update 24Oct25 ~ Baffle Diffraction Step (BDS) Loss Correction, Circuits, & Testing... I've modeled and built circuits for narrow baffle speakers (like these) before. Lower frequencies sound 6dB lower below 8X the width of the baffle as to wavelength. (1/8 * 13560 in/sec)/5.3in ~ 320Hz for these. That's about right from initial testing (in a sub-optimal room location). The circuit which will reduce frequencies above this by 6dB uses a 1mH inductor in parallel with a 7Ω resistor in the powered signal path. The parts I used and circuit design are shown below along with my completed 'packaging' of the circuit. $20 got me parts for 2 pairs of these BDS loss correction circuits. I don't generally like to just 'create heat' but in the interest of a flatter SPL sweep, I'll do it.

As mentioned far above... I don't feel I need the BDS correction circuit in the speakers' final locations.
