      The largest speaker I ever designed was these. I didn't build them, but I did the crossover and overall design. I think about them all the time. They were wonderful. Sadly, the tweeters are NLA (and the mids might be soon as well). But maybe someday, they can be reborn with newer, easier-to-obtain drivers.

          Yeah, that was a customer build. They now reside in Vietnam. Ryan does the finish work. I programmed the CNC and prepped the stacked ply cabinets with a pneumatic sander. I dont recall the veneer name though. Ill ask Ryan for the species. Check wood-veneers.com. Awesome variety!

            The largest speakers I've built we're the Omegarays which stood 6'4" tall. They had (10) Aurum Cantus AC130 MKII woofers with (8) Founteck CD2.0 ribbons. The bottom compartment contained a 12" AE (Stryke) sub which was actively powered.Rick Craig designed the crossover for the linearray portion. This was back in 2003 and I used them until the Statements took their place.

              Yup, 6' 4 1/2" tall. The tweeters and woofers were all pretty good vifa drivers at the time. It actually didn't sound as bad as you'd think it would. No distortion that I ever heard. I was around 30 yrs or so old at the time. All oak and particle board. Weighed a ton, the base was solid oak and that alone must have weighed 50 lbs...At least the cabinets were solid.

                You’ll have to excuse the mess (was still in the setting up stages), but here is the biggest sub I’ve built. It was in our old place for our bedroom system. It’s a sub/component holder, at least that’s what I told my wife. It housed 4 tc sounds epic 12s and if I remember it was right around 14-16 cubic feet tuned to 20 Hz. It was powered by a Peavey IPR7500. It was overkill for our 12x16 bedroom.

                  RSS390HF-4 up to 150Hz, SEAS W18E001s from 150Hz to 750Hz, modified Altec 511 horn with TAD TD2002 driver from 750Hz on up. The center of the horn sits at ear height, 35". Active crossover with all slopes LR24, using a modified DCX2496, with QSC RMX850 amp for the bass, Parasound Halo A21 for the mid, and First Watt J2 to drive the horn. I intended to finish them, but once the engineering and construction was done I just never got around to it. Probably never will

                      I'm 6'2" and these are just a shade shorter than me, so very likely 6' tall. Dual 12's and single 18's. This is my best friends in-laws garage stereo. (No I'm not joking). The largest setup I've built from scratch.
                      Your results may vary.

                        LOL, is there enough room left to wrench on a car in there?

                            Good to see someone else using the venerable 511B! Very nice looking, too! Is the super tweeter between the horn and woofer?
