2 REL Strata Subs and Mono amps

The C1 IIs sound better than the Mk Is, but I would take that Diablo bargain from your dealer in two seconds flat!

By the way, I used a Storm III for many years with several speakers, including B&W Matrix 805s, 805s and 804s. One thing most people don't know about RELs is that they can improve the bass of almost any speaker, but that's not their main advantage; it is the way they improve the soundstage and the general sound of the main speakers because of the ambient clues hidden in the low frequencies and the way they 'come from underneath' the main speakers.

Enjoy the music!

Yes, I've just checked the Gibraltar G1 manual, and they indeed give on the p. 12 the same advice Al gave to me above (if power amp is balanced ie differential).

What they don't say is what to do in case of having two subs (stereo sub system) and balanced amplifier, as I have... Following strictly their user guide (bottom half of the p. 12), an average audiophile in my position will normally connect even fully balanced amp with two subs, the way REL suggests, and probably damage the amp.

Good that you say that, I thought about it but at the end didn't write anything. I used my REL Storms with mono and stereo amps at different times. The example on pag. 12 (top) of the REL manual is of course for a stereo amplifier; for mono amplifiers, use the pag. 12 (bottom) example and just imagine the gray amplifier divided by a vertical line through the center, so that you have two separate mono amplifiers, a left one and a right one. The potential grounding problem still stands, so it's better to ask Krell or get your dealer to do it.

Zormi, I forgot to add that you should copy the grounding scheme of the pag. 12 (top) example for the (bottom) example, of course. I think the chassis screw grounding will work for Krells, but ask them first just to make sure.

Very insightful thread, for me at least.. Grateful to all of you.

Happy New Year to all, lots of music!
