Sb Acoustics SB26ADC in Pureshape + Purifi PTT8

Id buy that. Amazing job. What’s the vertical directivity like with such a low crossover?

I have done some measurements and it looks good enough about +-30 degrees. I havent published vertical polars bcouse my measurements for vertical arent that good bcouse difficulties measuring it . xo is about 1100hz now and i like it the best. Tweeter distortion is still really low but it might get warm with high spl tho.

It looks very, very good. Too bad that they don't want to sell file to print this waveguide

Well its way better business to sell them finished so i understand it.

Numbers would be really nice since the supplier is only publishing 3rd order distorsion.

Hello sry for the late reply. Here is distortion measurement but its for the whole speaker and xo point is 1100hz 24db/oct. 93dB 1m

Got the second woofer finally after months.

Hell of a long time for the driver to arrive.

But they certainly look too class sir.

I’m jelly.

Here are some measurements i took outside when i assembled the final xos.

Really nice work integrating those drivers!

Here is full CTA 2034 data and raw off axis. I made some slight adjustments to xo and lifted 1-1.8khz area little bit on axis.

I’ll have to say it again… it’s much like splendid sorcery to me.

If you ever commercialise them I’d be up for a pair.

Great results! Do you like the sound of those Purufi woofers? Unlike 6.5", these bigger ones have a dominant 2nd harmonic at the low end. Do you feel that fat bass?
