Any plans for a narrower version of this speaker using the 8" servo units?
There is a smaller version with a single Neo 10, one Neo 3, and three 8" servo subs all on an open baffle. 93db sensitivity.
Also wondering, were the 4 BG Neo 10 panels used to increase sensitivity? Curious why 4 were used as opposed to 2.
Two units can only be wired in series or in parallel. So the impedance would be either 16 ohms or 4 ohms. 4 ohms doesn't make them tube amp friendly. Four of them in series parallel wiring gets them back to 8 ohms and increases sensitivity to 96db. Sharing the load with that many Neo 10's also reduces their work load to 1/4 that of a single driver.
Thanks for mentioning that. My first reaction was concern about vertical lobing, but thinking about it should not be a problem, if as you say they don't play high enough. I'm sure they play high enough for the top Neo10 to interfere with the bottom Neo10, but the inner drivers will lessen the effect by filling the nulls in. Am I far off?
Drivers have off axis narrowing based on the width of the diaphragm. This is exactly the same as the comb filtering effect of using two drivers covering the same range. Anytime a driver is playing a wavelength that is shorter than the width of its diaphragm then it beams, or losses off axis response.
So basically if you stand one Neo 10 up vertically then it has the same vertical off axis response as two Neo 10's on their side because the height is the same.
How is the distortion of Neo10 at high SPL? Of course sharing 4 reduces the distortion. But can they play really loud classical music (low frequency brassy dissonance) like a high end 4 way cone speaker - without breaking up, hardening tone, or dynamically compressing? These look promising!
They play really loud very easily and very cleanly.
