How many subs?
I got my room analysed by an acoustic engineer.
3 subs - 2 with delays.
Maybe I did not have the gain set right for each sub?
The pressure in the room was overwhelming. Opening the door was a relief.
One sub - front left - the one with no delay in the design seemed really good.
But I got hungry for more - so I tried 2 subs.
Does anyone have experience with using a multi-sub setup using delays?
@jayctoy any number of subs is good - I just got the 3 sub system going with some outrageous hardware. It sounds fantastic. Not the lowest bass - I don't want that (yet). Delays with a Drive Rack. Low pass filter for the right subs with a CR1 - nothing spared. I need some tweaks to get it right. When you hear a Tyrannosaurus Rex on S/510s - you will run. |
Everyone will be pleased that the experimentation with delays for subs 2 and 3 is done and it is a fail. It takes a few sessions and many tweaks of levels to hear what is happening. To get the sound so subs 2 and 3 don't noticeably interfere with the main speakers is a very low level. I turn off output 1 on my amp and listen to only output 2 which feeds the 2 delayed subs. Really not a lot happening. Not worth it. |
@bilateral Just a thought. Saturday January 11, I filled in on Bass at a benefit held in a medium sized hall. After the sound check I noticed the front of house equipment rack included a 1U spaced component called DBX Drive Rack (something). The tech had left after the check. He was still working after I left that evening so I was unable to question. I think it might be a more recent Auto EQ system for both stage and / or front of house EQ. Just how this would function using REL's preferred speaker/high level connection without also affecting the mains? Front of house or FOA sound is a whole other world of audio. You might want to get clarification as to what the intended use of this DBX Drive Rack model is designed to control. Don't give up on your low frequency reinforcement. |
@m-db the drive rack was not used for purpose, it was what it could do. I wanted a balanced product that could give delays up to 10 ms (not including latency). When the Acoustic Engineer said 3 ms delay there and 9 ms I got someone else to program it because we could not work it out. I cannot use Rel's preferred method of connection for sub 2 and 3 due to the delays so it is the 0.1 input or whatever it is called. Then the problems with the 120 Hz 4th order low pass filter on the subs - it is worth mentioning again - this is not the filter for hi-fi. Too much higher frequencies. I have the JL CR-1 to fix that. Is today today? Good it is. 3 days for suggestions for testing. |
