Hi @fastfreight I do have the phase corrected on the sub using a software from Rational Acoustics. The pros use this for phase and time alignment but for this is probably overkill. Honestly, if done properly you will hear it louder around the crossover point usually because of summation and that is what is great about this software. You can see the changes in real-time and not as a screenshot.
Gain level on a REL sub
Hi. I have purchase a REL R 218 sub to compliment my system and as far as sounding musical, I am happy. However, the gain is almost all the way up and I don feel that punch and slam I am looking for. Musically I am impressed with it but I still dont feel that level of impression overall. When I had the HSU STF-2, it was in a different league with in terms of impact and punch but for detail, the REL was better. My question now, Do you think I should try getting a another REL with the same model for a stereo pair or go with a different sub? My room is pretty small but it is treated with acoustic panels.

Thanks @highend64 . Well I am stumped. While I wholeheartedly agree one sub is not as good as two, you still should get good volume and punch out of one. For High level, you are tapping out of the amplifier outputs? How are you connecting this as you have one sub and four amplifier outputs? Have you tried just connecting to L and R outputs of one channel or one amp? (using the Speakon connector and Red / Black wires?). |
My REL r305 is very similar and I’m running it speaker level from a 40 watt Integrated amp and I only have the volume 5 clicks up from zero and a low crossover and it is plenty loud and keeps up with a pair of 88dB sens speakers easily. Just a few clicks up and it is way too loud. 12x 14 room , well treated it almost sounds like it’s not getting enough signal from the amp For troubleshooting purposes I would strip it down to its most basic elements, no EQ Just the amp, speakers, sub , and a good line level source

@OP. I know you say the situation was different with a previous sub, but perhaps you are expecting too much of the Rel. There's only so much a sub can do when the main speakers are limited in frequency extension. But even given that, there is no way that any Rel sub should sound insufficiently loud - even well below its maximum gain setting. If you connect using the low level input you can use a set of test tones and an SPL meter to get an objective measure of the subs output. That will be of use to you in moving the sub around in case it is on a null point in the room. |
