Have you got the passive radiators as well? …Interested

Thank you, Zen. There is completely a zero percent chance of me selling them or ever making cabinets for anyone else.

OK Thanks for the heads-up. I'll be on my way.

Have them set up and tuned now. Was feeding them some Dire Straits and Pink Floyd yesterday afternoon and I'm well pleased with the sound quality, impact and look. I have a Fitzmaurice HT Tuba to augment the bottom end, but these sound really awesome as-is. plenty of bottom end. Still need to install some proper speaker terminals. I've raised the top hat off the bass bin with gold/black chrome spikes and pads. They really look sharp I think. I was worried about WAF, but she loves the veneer. Finished with 3 coats of Waterlox original and orange oil/beeswax polish applied with a green scotch pad and buffed.

With mockup and adjustments (there were a couple from the drawings and cut sheets, and adjustments for 3/4" MDF Dimensions) Ready for veneering. This was a bit of a PITA. As I said, I had the bosse spanish cedar veneer for a while, and it was dry. being raw veneer, it was brittle and fragile. I used the titebond iron-on method. I used both titebond II and III. It's really never failed me... until I started matching seams with this super dry veneer. I'd get the joint tight and nearly invisible. Then it would suck up moisture from the glue. I'd lay it down and hit it with the iron and the veneer would shrink, opening the seam. So It was quite a bit of work trying to heat and slide the seam back together tightly while the glue was still hot, and tape it in place while it set. Wasn't easy doing it alone, but I was able to get through it and it came out decent.

Hey, y'all... been a member here for a few years, but a while since I last posted. This forum started for me back when I built a set of custom cornscalas with a curved sided bass bin, similar in size/shape to the Volti offering, only in a bass reflex ported config, tri-amped and active. Had those for a couple of years then moved to the Linkwitz 521.4 open baffle. Those actually sound completely amazing, but totally missing the impact that I like so much. For sound quality, nothing I've heard compares to the 521, but like I said, they did nothing to pressurize the room. So, a life-long admirer of the Belles, and always wanting a pair (of Belle speakers) my search started to find something reasonably priced and in good condition. I could never find these 2 qualities in the same set of speakers I had found for sale. So I figured... I have a nice wood shop setup, why can't I build a set with the available reverse-engineered drawings out there? I initially thought it might be a bit of a gamble in that I wasn't sure if the drawings were accurate enough to build from, but thought again... why not? I can lay everything out and adjust if necessary. I bought 3 sheets of MDF to start, had a glut of bosse spanish cedar veneer I bought off Ebay a few years ago, and the drivers from my scrapped cornscala project. Those consisted of Cast frame Crites woofers, Eliptrac 400 with a Community M200 2" compression Driver and an Eliptrac HF with a B&C DE120 driver. These are also tri-amped and active. Outlaw 7 channel x 100W amp and a DbX Driverack PA2 crossover/DSP for now, possibly swapping to my minidsp4x10 at a later time. Here I've got everything roughed out, laid out and ready for mockup, hence the green tape...

We usually get the grandkids from Ohio to stay a couple weeks up here in Maine... rent a place on Moosehead lake, do some fishing, take a trip to the coast, eat lobster, play in the water and generally have a blast with them. This summer my daughter is getting married in Boston, then a party at the house the weekend after. We'll have them for a couple of weeks, but are set to freelance... maybe Bar Harbor, maybe the southern Maine coast... whichever way the wind blows. I CAN"T WAIT!!!

Great job on those, for sure! They look awesome. It’s definitely a labor of love, isn’t it? Love the figured cherry. I almost went with the figured cherry I have on hand to veneer the Belles I’m currently making, but opted for the highly figured Bose Spanish cedar I had scored on an eBay auction 5 or 6 years ago. Veneering the panels flat on a bench is pretty straightforward. Veneering angles inside of a box with contact cement, mind you not so much!

I, too was looking around for a set. There’s a pair for sale locally here in central Maine. I’m thinking he’s asking quite a bit too much given the condition… $3500 and the veneering needs help… So I’m building my own…. I’ll still keep my eyes peeled and let you know if there’s anything worthwhile. Also, let me know if you’d like some info on the set I previously mentioned BB

Nobody mentioned the DIY route: Fitzmaurice HT Tuba or similar? And fwiw, I firmly believe class D is just fine for sub duty.

I've got the Community M200 Mid driver in an Eliptrac 400 mated with a B&C DE-120 in the Eliptrac HF. I'm set up with an active 3-way system using a DBX Driverack PA2+. This crossover/DSP uses a measurement mic for in-room calibration. I think it's a marvelous setup. Couldn't be happier.

Good afternoon, everyone, I just built a set of custom cornscalas. They are 2 piece cabinets with a sort of truncated ellipse design (curved wall cabinets). The top sections have Eliptrac 400 horns with a Community M200, and an eliptrac HF with a B&C DE-120. My current setup is running them active through a DBX Driverack PA2+ Crossover/DSP from my Denon AVR-4200, and into a Crown XLS 1502 for the bass, and the mids and highs are each driven by Carver PM-175s. I've added Solid State Relays to the Carvers for 12V trigger. I have a second Crown 1502, so I'm wondering if there would be any benefit to adding another Crown to drive all (6) channels with the same type of amplifier (class D) or finding another Carver to match, or even selling all 4 and buying a different amp? What would any of you suggest? I'm not looking to spend a buttload of money for a boutique amp, but I do like the raw power of the pro amps in order to have plenty of headroom. The way my current setup is dialed in, there's absolutely zero strain and nothing gets hot, and it will still make you blink with a snare drum at less than half volume Lay it on me.

Thanks! I'm not exactly sure how low... I'll need to sweep them with REW to get a frequency response plot. I've got a calibrated measurement mic, so it wouldn't be too hard to do. I can tell you that the cabinet volume calculates to 6.59 cu ft, taking into account the bracing and driver volume. I have (2) 4" round by 8 3/8" long flared ports, and the tuning should be somewhere in the 31.5 Hz range. Fs of the Crites woofer is around 26, I believe (26 and change). I've added a little subharmonic synth from my DBX driverack, which boosts and extends the low end as much or as little as you want. I formerly had 2 Polk 12" subs that are completely useless to me now. These seem to go a bit lower, and with much better resolution. The will rattle the windows if I roll the volume up, and I'm sure it will only get a bit smoother once the drivers settle in and loosen up a bit. I'm not a huge bass freak, but I am really impressed at the sonic impact these deliver. I'm using these to replace a pair of towers I built a few years back using (2) Seas 8" high resolution drivers and a Fountek ribbon tweeter each. They sounded sweet, but not even close to these as far as realism and impact. I'll see if I can set them up for a response test sweep in the next couple days and post the result. Thanks, No.4! I really appreciate it. I know they all look rough before finish, I just usually wait until the cabinets are done completely before bringing them in. I'm VERY fortunate to have such an understanding wife. She knows it's what I gotta do! Although, She's not going to let me leave them looking like that for very long in her living room!

I'll also be making a cutout in the bottom of the top cabinet for driver access and adding nice binding posts with brushed aluminum plates on the backs of the cabinets. They look pretty skanky at the moment, but will look pretty nice when they're finished, I think.

Please don't mind the appearance. They are in progress

I'm a bit embarassed of how they look at the moment in their raw, temporary state, though... I'll be adding plywood/MDF sides to the tops, and 1 layer of mdf to the lower cabinets after leveling and truing the surface. The veneer will be 2 ply cherry, nothing overly fancy. My goal is to match the color/grain of the entertainment console, which is the trade-off with the boss. I'll be painting the horns flat black, and both the tops and bottoms will have flat grills made with acoustically transparent cloth from Parts Express, and attached with rare earth magnets. The cloth a turquoise/white/silver pattern. Sort of like the Fender amps of old. Water jugs made for good clamping pressure when gluing the internal braces together Top cabinet viewed from the top

I can't beleive there's been so much time that has gone by since I started this project, but I've actually got the cabinets built, drivers installed and in my living room playing now. It's been over a YEAR to get these to this point. Still need to veneer and finish the cabinets, but just couldn't wait any longer to test them out Oh, my! they sound absolutely FANTASTIC and well worth the wait! Ive built the semi-elipse (bent plywood laminated sides) bottom cabinets that stand 30" tall and are 23" wide and 23" deep with Crites cast frame 15" woofers and (2) 4" flared round port tubes. The top sections are 21"W X 14 1/2" tall and 17" deep. Each are loaded with Eliptrac 400 and Eliptrac HF horns. For the mids I ended up using some Community M200s that I've been holding on to for a long time (thought I'd try them first, 'cause I had them on hand), and the Highs are B&C DE-120s. They are set up as active from my Denon AVR-4200W, through a DBX Driverack PA2, and (3) Carver 175W 2-channel amps. Crossover points are (for now) 450 and 4500. At first I thought they were a tad harsh in the mids, a little honky, even. I ran the auto EQ from the driverack and they are now very flat for my weird room with cathedral ceilings. I added a little sub-harmonic synth for the low end, and HOLY COW! I know some of the purists out there might scoff at my setup, but damn. I've never hear anything sound so sweet. I listened briefly to some Pink Floyd (The Wall, Dark Side Of The Moon, Wish You Were Here), some Diana Krall (From This Moment On), and various other stuff. I am thoroughly impressed. I immediately removed both of my subs. No longer needed at all. The mids are crystal clear and effortless, the bass deep, low and heart-thumping, and the highs are shimmery and sweet. I'm a definite fan of active crossovers/DSP, and the Community drivers are very hard to beat, IMHO. I just can't believe the bass extension. I really wasn't prepared for that!

I found the TS parameters. Thanks, Mustang Guy for posting them! (seek and ye shall find!)

I wondered about that coax....

I think I might do some experiments... I just ordered some Eliptrac 400 and Eliptrac HF from Fastlane. Mid and High drivers are still up in the air at this point. Has anybody looked at the Celestion Neo 2" CDX20-3000? On paper, it looks like it might be a contender. I definitely want split cabinets. For the Top, I'll make a removable front panel (motorboard) so I could also try 2-way and do some testing in both modes. Woofers will probably be the Faital Pro 15PR400, Or Bob Crites Cast 15" woofers, but I'm open to suggestions. I've looked around for the TS parameters for the Crites cast woofers, but haven't found any data. Anybody know where I can get my eyeballs on it? Bryan

I agree, Tiger. The vertically oriented horn looks funky to me. Thanks for the link! I'll be sitting about 10-12 feet in front of the pair of speakers, and they will be about 12 feet apart. You don't think that would be too close for a 3-way design?

Nice... are you using them in a 2-way or 3-way setup?
