Syzygy subs, we’ll built & have EQ, works extremely well. Out of business but still may be able to find.
Subwoofers with room correction built in?
Who has experience, good or bad or whatever, with the built-in room correction/DSP/EQ that newer subwoofers (except REL) come with these days? I’m excited to try the system built into an ELAC sub 3070 that’s coming my way soon, but I want to be realistic.
Thanks.
Thanks.

Martin-Logan X series can be used with a smartphone app that is OK. Much better results w Perfect Bass Kit. The smartphone app is good for tweaking phase and level to fully integrate with mains. In two years, the only negative is they are light and require mass atop them if they are on a compliant floor, i.e. media room above a triple garage with an unsupported ceiling. see http://www.ielogical.com/assets/Audio/SubWeight.jpg - somewhat low WAF factor |
redwood, room control is really speaker control. You are adjusting the speaker to suit room acoustics AT THE LISTENING POSITION. Everywhere else in the room the correction will be wrong. You still have to do your best to improve room acoustics. The Room control in subwoofers is extremely basic. It can only adjust frequency and phase. It can not correct group delays and most subwoofers have low pass filters only and not two way crossovers. These are two serious flaws if you are looking for the ultimate bass. Having said this a sub with room control is better than without and using two of them will be an improvement in most systems The absolute best way of going about this is to get a DSP preamp like the MiniDSP , Anthem STR or DEQX Premate. Then build a passive sub from a kit. PartsExpress has a lot of them. Then get a commercial sound reinforcement amp with a high damping factor >500 and a lot of watts. I like QSC products over Crown. With a system like this you have digital control over everything including the crossover. If electronics are so susceptible to vibration why would you want to put them inside a subwoofer? |
@mijostyn…+1, Most often folks neglect the listening position altogether when going through the time and expense of setting up subs in the corner or alongside walls. It defeats the purpose for the ideal end state. I am close to that level of tweaking “get a DSP preamp, MiniDSP, etc.” except not building a passive sub with an external amp like you did. Perhaps, you can sell your DIY kits for the masses:)😀👍 |
