2 REL Strata Subs and Mono amps

Wow Vladimir..

Nice idea with C1 MkII, already under consideration. I know them well, since I use to own original edition Confidence C1... In fact, I owned both Utopia Micro Be and Confidence C1 until the end of 2008, simultaneously. Two different worlds, each one impressive on his own way... I now prefer a bit the Utopia Diablo because a slight edge over Dyn C1 in mid/high clarity and detail rendition. Bass aside, this is where C1 excells, but RELs defeat that area as a serious issue. Price wise, I have a great dealer from Belgrade, Serbia, which is able to bring me a pair of Diablos including dedicated stands for the same money as pair of C1 MkII without stands at another dealer. But, price doesn't matter too much... differences between the two simply not prominent enough to have any serious impact on decision.

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.
