I have a lot of interest in the NX-Studio and initially thought I'd have interest in the "floor standing" version of that speaker which has been discussed before... the one with 2 woofers from the X-Statik bottom end. Looking at the low end of the X-Statik (-3db down 48Hz), I would still need subs - which I already have. Running the "floor standing version" of the Studio passive, means more crossover parts / complexity. I've expressed interest in the floor standing version and it sounds like it's something that is out there, but not necessarily a huge priority, and maybe I'm coming to realize why. I've read Danny's comments about the floor standing Studio idea and it sounds like it's not necessarily a slam dunk / clearly better option than just adding quality subs to the the NX-Studio and incorporating a high pass filter - especially when you consider the tuning ability for the low end, which I'm not sure I'll ever be able to live without after experiencing it. The high pass filter I have is a pretty slick setup; although I've yet to put it in the system. Ayre Acoustics offers a mod to incorporate the filter into some of their amps which have the space for it - in my case an Ayre VX-5 Twenty. Evidently this is a common setup they provide for Vandersteen Audio speakers using Ayre amplification. 100Hz high pass / 6db slope. Since the input impedance of the Ayre stuff is 2 Meelllion Ohms, the caps are tiny.
I am currently running a pair of SVS-SB16 Ultra subs with a pair of 2-ways that use an 8" woofer / soft dome tweeter. Blending subs with quality 2-way speakers is a recipe that is really tough to beat. One thing though... the 2 way speakers I'm using are 90db sensitivity and I've really come to prefer that level of sensitivity compared to some 86db speakers I had in the rig recently. That brings me to the NX-Studio and the 87db rating, and it's something I've never thought of / don't know the answer to...
If you run the NX-Studio with a 100hz 6db slope high pass filter, will that have a positive effect on the measured output sensitivity of the NX-Studio? If so, how much? I know the idea is that the HP filter will also allow them to play louder, which is great for dynamics every now and then, as my current 2 way speakers with 8" Scanspeak woofers can play BIG... REALLY FRIGGIN' BIG. I'm enjoying the dynamics from them, so this is all a bit of a conundrum... life is so hard sometimes...
