Running Two REL Subs off One Amp - Possible?

If your amp has bi-wire outputs you could run the right sub from the right outputs, (connect the two positive and one negative) and the other from the left output. I don not believe that using the line level output is going to let you adjust the crossover for integration into your two channel setup. If you are using these only for HT, the processor would obviously set the crossover. I currenlty an only using one Rel but down the road would like to add another.

Howard: I have the McCormack RLD-1 preamplifier also, just like you (with the DNA225 Power Amplifier, both of them recently upgraded to Platinum Edition by Steve McCormack) and I am also thinking on Dual Subwoofer. Why are you running your subwoofer from your amplifier instead of using the RCA at the back of the RLD-1 preamplifier ? is there any acoustic advantage plugging the subwoofer at the back of the amplifier instead of going from the preamplifier ? you could use the right chanel for one subwoofer, left channel for the other subwoofer. By the way, I am considering Dual SVSound PB12 Plus/+2 or a single PB12 Ultra + 2, what do you think is the best option ? My speakers are Ambience Superslim 1800se Ribbon speakers and the rest of my system includes Metronome Signature Transport and d.a.c., Acoustic Signature Final Tool Turntable, Magnum Dynalab MD100TR Analog Triode Tubes FM Tuner, with high-end power cords, interconnects and speaker cables. Looking forward your comments. Best, Antonio Machado.

I use a REL and have been thinking of perhaps adding another, not so much for bass as for balance. I am using the Neutrik connector (I think this is called high-level connection?) in which the SW draws nothing but the faintest signal from the amp.

I would think doubling up the connections (ie the second sub) should be fine. But have not tried it.

Regarding position, this is one reason I have not gone to two subs yet. I am on a suspended wooden floor (basement below) and have noticed, when this down-firing sub is away from the walls it excites the floor more - simple physics, as there is more flex to the floor the farther you get from the anchor point, ie the wall). Of course, this would indicate that a corner would do best in that regard, but that excited too many room nodes, and I ended up with it a few inches from the left wall, and about 3 ft from the left speakerm, more or less in a plane with the speaker baffles.

Am concerned that bringing the sub too close to the speaker would cause some 'bounce' in the speaker (mine are not too heavy - only 60 lbs) and smear the sound from the mains.

I just recently added a second Rel Storm III to my Pass Labs X-350 Two channel amp. I put both the positive (+) leads from the high level connection (yellow & red) to my positive post on my speaker, then the single black negative (-) lead to the negative post. I did this for both channels (Speaker to Sub). It is cleaner looking than having all those wires running to your Amp.
I have Audio Physic Virgo II speakers. It is absolutely the best sound I have managed in my cavernous listing room. Positioning your subs is all about your room and your wife. I put my Rels right behind my Virgos, not as close to the corners as I should...(a man needs to know his limitations, wife factor not in the setup instructions from Rel). The Cherry finish of both Manufacturers match well... so I'm also a good boy!
