A new reference line array.
« on: 26 Mar 2019, 12:38 pm »



Ten SB Acoustics Satori 6.5" woofers and fourteen BZ Labs CQ76B tweeters in a sealed box, bi-amped with a DSP crossover. Measurement graphs coming soon!

Very nice!  What amplification?  Kit?  Cost?

"A new reference line array". This new design will this surpass your previous efforts with CBT line arrays?

It's design for amps that can handle a 4-ohm load and typically in the 100-400 watt range. I haven't priced the kit yet but assembled shipped to the USA would be in the $14K-$15K/pair range.

The drivers are superior to the CBT arrays and the woofers larger for greater dynamics and lower distortion. Low level detail is especially good and instrument placement is excellent! To top it I would need to do a CBT with drivers similar to these.

All of the following response curves are 1/12 octave smoothing and taken in-room. No gating was added.




Measurements on-axis at 2,4,8, and 10 ft. distances.




Vertical response curves taken at 8 ft. distance.



2nd/3rd harmonic distortion at 1M distance and 100dB at 1K reference.



Woofer line impedance.



Tweeter line impedance.



On-axis, 30 degrees horizontal woofer side (HW), and tweeter side (HT).



On-axis, 15,30,and 45 degrees off-axis horizontally at 5 ft. distance.




Nearfield bass response (no EQ added).




Nearfield bass with EQ added.

Thanks, dunno how I missed that.  I can only claim senescence.

You and me both buddy!  :thumb:

Hopefully we are wiser though...  :wink:

Beautiful!  What are the dimensions on that?  HxWxD ?

Absolutely gorgeous. Would love to see pics of the pair when all properly set up.

72" high with the base, 13 1/2" wide, and 10" deep.

They will go behind a screen eventually, so they are not very deep.

They look imposing, but once in place they take up very little floorspace.

Still looking for a new amplifier(x2) to run them just havent decided yet... :)

I think you meant 72" ?  How much do they weigh? I'm sure they are going to be great.

I sort of have dreams of something like that flanking a fireplace hidden in acoustically transparent caryatids or columns.  Then I think that might be too Hugh Hefner.

You're right :) 172" was a bit tall!
