Sorry for the delay, I missed your post.  I've ordered 80/20 aluminum pieces for my next attempt.  They can be used to build whatever you can imagine without welding.

I'm looking forward to seeing what you come up with!

Going on close to three years with this set up.  Man, I'd like to try something different, but I keep smiling when I listen.  Speakers are a design from Scott Faller (Lowther PM5A) and I added the Tone Tubby Alnico driver based on a Jon VerHallen design.  The SVS sub blends in to support under 80Hz

That's a sweet setup... :popcorn:

New member here but been with other forums & building Obs for many years. These are based loosely on the Pure Audio Project concept. Speakers are 3 way, measuring very flat down to 30hz with subs phase/time aligned at 50hz (it's a 5 way 2 channel system, two DEQX processors)

Beautiful work!  But how do you get a 5 way speaker?  I only see 4 drivers there.

It's a 5 way system - 3 way speakers plus two subs. The master DEQX processor (HDP-5) handles the 3 OB stereo channels, the slave processor (HDP-3) manages the subs. All drivers including subs are calibrated using outdoor measurements and phase/time aligned across all frequencies.

The Beymas handle only 50-280hz. Transients, including bass frequencies are extremely dynamic & life like (much as other open baffle users would probably appreciate). The subs add a level of reality that is difficult to achieve with pure OB bass - something like a foot stomp within music sounds just like someone is walking softly in a different room above, more 'felt than heard'. I like (& need) that.

I voiced these speakers to sound somewhere between PAP Trio & Quintet 15s & having heard both types several times before/after building my own variants, I must say that I'm extremely pleased with the result.

The listening room is very heavily acoustically treated and therefore the only digital eq needed is a 34hz 3dB reduction @ a 3.8 Q to achieve in-room measurements as previously posted.

These speakers were finished early 2017 & were the 5th variant of OB I had produced. DEQX suits open baffle designs very well and I would class the last two types as sounding pretty exceptional. I doubt I will ever need to build anything else.

I think you meant, "Maximalist."

Those are essentially in-wall speakers.

These looked really interesting! I like the blue color. Are you happy with the sound?
