Sub Question. One higher quality sub or two lesser quality? (Rythmik vs HSU)

I have narrowed my choices to one Rythmik Audio G22 Dual 12" subwoofer or two HSU Research ULS-15 II. I am trying to keep my budget to under 2K. I like the fact that the Rythmik is servo controlled and seems to be of higher quality. But I also like the thought of two subs vs one.

What say ye, Audiogoners?

As I read it the two outputs are already in parallel and connecting two subs to each directly would result in 4 in parallel which would could result in loads 2 ohms or less with nominal 8 ohm subs. Two in series to each would seem like a better idea?

Cornwalls are super efficient, so what Brian said makes sense.  I've never felt like they tried to upsell me when I've talked to them.  Did he make a recommendation for your situation?  I'd reach out to the guys at SVS and see what they suggest also.

Sorry I didn't go into detail.  

With one amp and four 4-ohm subs, the connection configuration is series/parallel, resulting in a 4 ohm load.  

With two amps there are several possibilities, but we never ask the amps to drive a load they're not rated for.

Duke, that makes sense. Thanks.

If Rythmik still offers a 10% discount on multiples, you should just be able to get a pair of the E15 subs for $2000. The only difference between the E15 and F15 is the size of the enclosure, and therefore a minute difference in output.

Whether or not the F12 would provide enough output for you is also partially determined by how loud you listen. The F12 standard uses the Rythmik aluminum cone woofer, the F12G the GR Research paper cone woofer. There is no F15G.
