NHT X1 and X2

Hoping to find some assistance regarding an NHT X2 I recently picked up on the used market . The unit ,however, did not come with a power supply . The back panel states 15V , but does not indicate the amperage .... 500ma , 100ma , 2000ma ? Before I purchase an aftermarket power supply was wondering if one of you kind X2 owners could take a look at yours and let me know what it says . Every online picture I could find ended up being blurry and unreadable . 

 

The main difference between the X1 and X2 is that the X1 has built-in bass equalization applied to give the Evolution subs a flat response. Without the EQ, the Evolution subs would naturally roll off at 58Hz (-3dB). You can find this in the Stereophile review of the NHT Evolution T6 system. Also after looking at the block diagram available at NHT's website, their subsonic filters vary (X1 is 26Hz vs X2 at 15Hz) and their lowpass frequency ranges differ (X1 is 50-140Hz while the X2 is 30-220Hz). The X1 should only be used with NHT Evolution subs (unless you want boosted low bass). The X2 is for everything else.

The W2 subs are the passive ones and the X1 is a part of the U2 package deal for the Evolution lines. I am planning to use the pre-out from the processor to the input of the X1 then from the hi-pass output L/R of the X1 loop back to the multi-channel amp and the sub-output L/R of the X1 to the each channel of two of the A1 amps . The X1 crosser set at 80hz. I guess the connections are too cumbersome but according to NHT that will give the M5s and the W2s the best blend-in. Also, the sub-out from the processor is connected to the X1's LFE in. Would you recommend any other better way to simplify my connections. You are right though. I probably do not even need the X1 if I use the sub-out from my processcor. Well, shed me some light here, I am getting dumb and dumber with my age.

Hi Bob, good to hear from you again. I am back. Somehow the HT bug got me while I tried to get out of the audio hobby. I guess I would need to buy the X2 for my Classic line speakers and leave my x1 alone with the M5s. Thanks again, Bob.
