Absolutely. They´re beasts. That was the reason for purchase. 2,5" voice coil and very strong motor will do badass things when driven properly and in groups.Hey Petr,
The 8NDL64 is a crazy good deal, probably our highest performance 8" and almost our cheapest as well.
Just hits that convenient sweet spot.
So I really hope I´ll solve that noise issue one way or the other.
Yes, I´m well aware. Had this 8MBX51 "decision time" too. Very nice and light driver. The box will experience some regular PA usage though, so more robust motor and larger voice coil with higher impedance (efficiency) will be handy. I probably shouldn´t mention that "Hi-Fi" term. I meant mixed and home usage. Like, EAW KF394NT ballpark of power density and lovely sound. No LA I had a chance to listen to, would touch this. Especially not for close-up listening like 2-5m. And while the stereo speaker set will be made of 4 pieces of 8"s, and I don´t require LA output capabilities, it all fits together so it should work towards the expectations...Anyway, for hi-fi applications I normally recommend something wider bandwidth like the 8MBX51 or the 8BG51. The NDL series is designed for line arrays, so full range enough but light weight and high power first of all - and assuming subwoofer support.
I also expect non-conventional design of mine will require a crossover, which will allow the box impedance to drop very low at the crossover point. Here again, higher impedance drivers come in very handy...
I will always use it with subs. For calmer listening sessions, crossover frequency should be around 80Hz, for PA usage, 95-105Hz will do. But it´s all in very early development stage. Time will tell how good decisions I made.
