@hilde45 I have two (2) REL T5i's in my system. They are more than enough for my small room. I believe that two 8" drivers ( in the two T5i) are more surface area than one 10" driver. IME, the room size is the real factor as to how many subs and the size of each...not 10" driver or bigger, etc.
How to connect monoblocks to a single REL sub with ONE RCA input
I just purchased two Quicksilver 60w Monoblock amplifiers and a LineStage Preamp by QS.
To connect this REL 328, normally one uses connect their Speakon cable (Red, Yellow, Black ends that connect to Right+, Left+, and Ground) or a SINGLE "low-level" RCA in. But this preamp doesn’t have a single sub out.
REL’s advice is to buy a second sub and attach one sub to each monoblock. Well, maybe I’ll do that, but in the meantime, I’d like to be able to hook up what I have.
Should I orient the amps so that the speaker terminals are close enough together to attach the strands of the Speakon cables? I have been warned by REL not to hook up high level to monoblocks because it will create a ground problem.
An alternative is that I get a Y cable that will bring two RCA outputs from my Preamp into the single RCA input on the REL?
Or is there another alternative?
Advice appreciated. (But please try not to tell me to just buy a second sub.)

@ hilde45 you should NEVER use the high level output. Especially on a tube amp. Their use is strictly lofi. No professional installation uses anything like them. No matter what anyone says, they cannot produce accurate bass. Especially on a REL328 with no phase control. It's actually a polarity control. See http://ielogical.com/assets/SubTerrBlues/TubeAmpSpkrV.png and read http://www.ielogical.com/Audio/SubTerrBlues.php and https://www.soundoctor.com/whitepapers/subs.htm What you plan to do will be H U G E compromise over what is correct. |
@ieales I appreciate your input and will look at the links. There are now a lot of different opinions out there. The amp mfr says it’s fine. REL prefers high level to their own sub if there are two subs. Otherwise, they say low level but have no answer as to how to sum the stereo signal to mono. Others on this thread say both. Can you clarify what you meant by "Their" when you said: you should NEVER use the high level output. Especially on a tube amp. Their use is strictly lofi.Thanks. |
