Gain level on a REL sub

How do you have the REL connected? Maybe change the way you have it connected. Also, this appears to be a used sub, so make sure that it is actually working properly. 

Thanks for the responses. @soix I have not tried that crawl method but would be hard to do in my room. According to REL, the slope is rolloff a little to high. Rhythmik was one my option for a sub for some time.

@gkelly I have used high and low level connection and the gain is still the same level.

Hello @highend64 ,  something doesn’t sound right to me. I am a REL fan with a pair IN two systems. But even with one, it will easily play too loud. First thing, are you sure you have the phase correct?  I’m sure you know, but that is the first thing to adjust. You should easily be able to hear the bass go away and come in strong when the phase adjustment is correct.  If your REL  sub doesn’t have the ability to play too loud, then something must be wrong.

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.

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?).
