Bg Neo 10 and Neo 8

In my acoustically bright room, the controlled dispersion of the Neo 10 run as a mid tweet works quite well. Like I mentioned before though, the dispersion of the neo 10 is much better than that of even the smallest electrostatic device. But it still definitely needs to be listened to on axis..

Meh....

Some of it is good and some is marketing to sell his style of speaker. To say that his planar dipole only sends ONE sound to the rear and then it bounces around enough to sufficiently attenuate it that ours brains ignore it is BS.

In regards to that particular statement, I totally agree with you. Oversimplifying a concept to get the message across to laymen can cause a lot of confusion( It can also help sell your product..)..

Wishing the Neo8S was out last year. I would have used 4 per baffle and put them in a ring AROUND the Raal kind of like a virtual coax. Just got a pair to test. Much improved low range over the regular Neo8. I will be using them in a 3 way, fully active studio monitor project this summer. Raal 70-20XR, Neo8S and Scan Speak 10".

Did you send the 8-s' to Zaph for testing?

It didn't even cross my mind this time. Too bad. I could do a test btw my regular PDR version and the S. Same box, same levels, etc...

He's testing drivers right now if your interested..

After listening to the Neo 10's as a mid tweet for a while, I have come to the conclusion (through deduction) that lower crossover points introduce audible intermodulation distortions(This is probably what you were hearing, Greg) to the upper frequencies. I found that the higher you raise the crossover point, the less the upper frequencies are affected by this mildly "zingy" artifact. In fact, with the higher crossover point, the zingyness totally disappears, with the highs being incredibly pure sounding. So ultimately the Neo 10 can be used either as a "controlled dispersion" mid tweet crossed over at above 600hz, or in a more conventional fashion from 300hz to around 3.5khz but no higher..
Here is an excellent description of TIM in loudspeakers..

I hooked my 50 watt tube amplifier up to the Neo 10's just to make sure that it wasn't the solid state amplifier causing the "Zingyness" problem in the upper frequencies. I'm going to listen again to them for a few days with a 300hz high pass filter to rule that possibility out. They probably should have been hooked up to the tube amp all along. This amp should love the Neo 10's purely resistive 8 ohm impedance. Let's see what happens..
