Speaker Level and LFE Sub?

I need a sub that can combine the high level signal from the output of my 2 channel amp with the LFE of my surround preamplifier. I have a REL B3 right now which can accomplish this task. However, I am not totally happy with REL. I have an NAD M2 amp and the REL doesn't do great with the high level connection. I tried using the REL cable made for digital amps with no significantly different results. The NAD M2 doesn't have a line out for sub. :(

The G928, REL and Thiel's SS1, SS2 etc with the smartsub integrator are the only 3 sub manufacturers I can find that can run speaker level and lfe contemporaneously. Any other subs that can do this? Any external sub eq or dsp that can run both inputs at the same time?

Yo Big D, or as we in Houston like to call Dallas, that little city in South Oklahoma, I am going to do the exact same thing that you are, that's how I discovered the Def Tech's could handle that.

I suggest you do as I did, and call the very nice folks at Def Tech and ask them about it. They were great to work with and described in detail how this would work, and said it would be no problem at all.

Good luck.

I really doubt there is a grounding problem here but I suggest you contact NAD since the M2 is the only strange item in this setup. None of the other items will be a problem.

Thanks. I really like the m2 but it's just a shame NAD couldn't provide a simple line out. NAD has documentation on sub integration but much will depend on the sub itself. I think it's best to contact individual manufacturers. I live in Dallas but I am really an Htown boy.

I narrowed things down to Def Tech's Supercube Reference and Martin Logan's Depth. I will get the reference. ML never responded to my question. However, Def Tech responded with the following answer:
"It would be quite acceptable to connect an LFE cable to our SuperCube subwoofers while connecting a set of high level inputs to the subwoofer. The subwoofers would combine or sum together any bass they receive from the speaker wires with any bass they receive from the LFE cable. The subwoofers would then play any – and all bass they receive."

thanks for all of your help.

Big D, tell me how you like it. I am going to go with 2 Supercube I's. That Supercube Reference is going to be a beast compared to the B3.
