Nice pictures of your audio setup

That’s actually the open baffle PureAudioProject Trio 15 TB, with the native crossover removed (biamplified via dsp) and the nominal W,FR,W changed to WWFR configuration.

The woofers are made by Eminence and the FR is a Tangband W8-1808.

The frame is very nicely finished aluminum.

Very enjoyable. Needs sub support under about 45 hz.

That's what I thought when I saw the metal structure. Very nice! Congrats!

The wide band 49CZ Zenith alnico's from 1957 with compression horns and Eminence H-frame woofers. Deep bass provided by "Bucket Subs" (plans found at Transcendent Sound)

How did you establish that?

Good question!

I could demonstrate it - and maybe you'll hear it too.

I designed and built these open baffle speakers using dual MarkAudio Alpair 12Ps from 150Hz to 3,000Hz, GRS PT-6816-8 dipole planar tweeter and a front and rear (of the baffle) back-to-back Jamo powered subs operated in reverse polarity from each other for dipole bass. There are two 15" subs in the front corners of the room. Everything goes through DSP for levels, polarity, delay, crossover and EQ. The mids are direct-drive and there's only a single passive 39uF film cap on the tweeter for DC protection. Each driver in the system gets its own power amplifier channel. On the floor, an Aiyima A07 for the mids and an A04 for the tweeter. (The mids and tweeter have 94dB 1W/1m efficiency.) This is all the front end of a 6.2.4 Dolby Atmos system.

Awesome!
