Nice!

My just fixed OB proto 3rd generation.
Supravox 215rtf64 + audax tweeter+BD15 sub. Sub powered with Hypex class-D. Sub in N-frame, inspired by Nelson Pass. Supravox in mini-baffle inspired by Linkwitz.

The whole thing sounds very fresh and crisp !  This is the whole idea, to catch the OB openness

Very nice.  Could you tell us more about that Infraflex woofer?  And what was the music selection in the  video?

Hello Greg,

look good bass 20 Hz at 100 Hz  105 db SPL /W/m

And one more OB for the forum...  my first OB build.
Front panel: 16" x 32",  drivers: Eminence 15LFA & Celestion TF1225CX coaxial.
Hybrid XO, Celestion has passive XO, between Eminence and Celestion it is active. Frequencies are 200Hz & 1.9kHz.
Denon AVR-2106 modified to Bi-amp use with miniDSP 2x4HD.
After some months of adjusting DSP settings, I'm still not 100% sure of correct sound balance.. measurements in small room are just pain.

Wow, very nice wood, do you would add a hat above the 12'':

[erkki]

Thanks. Actually the varnish stain worked out much better than I expected, wood is just cheap spruce from Bauhaus.

About that hat, would it be for controlling the directivity pattern?

[FullRangeMan]

Correct, it help more than looks.
Note that if the hat is a thin real wood flap it will resonate according the music, that can be good or no to the sound quality.

[Chops]

Almost nobody uses a "hat", probably because it has little to no effect at all on sound or directivity. If anything, it adds just a bit of bracing to the baffle.

Originally it was created to operate with bass freq which are less directional.

Wings yes. Hat's? Not so much.

Anyway, here's a quick pic of my temporary OB setup, just to break in the new Audio Nirvana Super 12's which are playing fullrange. Running a single Eminence Acoustinator N2012 Neo woofer per side to provide bass below 200 Hz, and they do extremely well in doing so, extending deep into the mid 30's.

Running a dbx Driverack Venu 360 for crossover duty only, 200 Hz @ 24 dB on the N2012 woofers. The AN Super 12's are getting a fullrange signal. Each OB is being vertically bi-amped by the Carver M-500t MkII amps.

The final OB will be very similar to the P.A.P. Quintet15, only using the N2012 woofers (four per channel) and the AN Super 12. Just ordered the last pair of N2012 woofers from Danny Richie last night. I can't wait to hear the final system results. These temp OB's already sound amazing!
