One sub, a two channel system ,one HT reciever ??

I have a nice two channel system that uses the Pre Out's of a HT reciever to a line input of my preamp to integrate the HT system with my two channel gear.

Right now, the sub is driven by the LFE of the HT reciever and bypasses the sub's crossover and it works well.

To use the sub with my two channel gear... it would appear that I take the power amp out put to the speaker inputs and then the speaker out's to the speakers and set the sub crossover where I want.

However, the manual says use either the line level input OR the speaker level inputs but not both.

a) what happens if I screw up and fail to unplug them appropriately

b) Is there a clever way to hook up the sub with my two channel system and the HT system?

Tcatman,

I agree with Shadorne's suggestion re high quality HT pre amp. Even my vintage Proceed PAV/PDSD pre/pro combination does a fine job managing the interface of my KEF 104/2s and Velodyne HGS-15, whether stereo or 5.1. I take the balanced LFE output from the PDSD to a Velodyne SMS-1 room-correction manager, then to the balanced input of the HGS-15. Crossover is set at the pre/pro to 80 Hz, the Velodyne crossover is switched out, and the speakers are set to small. I can adjust the level of any speaker with the PAV/PDSD remote, and I set them with a RS SPL meter using the white noise generated by the PAV.

I've tried variations of this setup, but this is the one I prefer. Experienced listeners tell me they are unaware of the sub as a separate source of sound.

It seems to me that my biwired KEF 104/2s are just a bit more transparent when the crossover is set to 80 Hz. They also sound fine full range without the sub, but the low pedal notes of a pipe organ, for example, are missing. The HGS-15 fills that in, and can provide that subtle more felt than heard experience when a big pipe is invoked. For HT, you really need the sub; for jazz and chamber music, my favorites, maybe not.

Tcatman,

My experience with Velodyne is with the HGS 10 & 15 subs, and they are indeed fine. Placing the sub on an Auralex SubDude is a big win.

I have a KUBE for my 104/2s that I have never tried. I've read it introduces distortion, but that may not be true, or an observation based on an incorrect hookup. Anyway, I'm happy with the 80 Hz crossover, freeing the 104/2s from LF duty. I could be happy with just the 104/2s in full range mode, as well. The only setup I don't care for is the 104/2s and the HGS-15 both covering the under 80 Hz range, and that seems similar to the mode you prefer.
