Hard to say astolfor. The ideal solution would be to get another s/510 and a stand alone two way crossover/room control unit like a MiniDSP.
Yes get another and stay away from bottom firing subs, unless they have a butt plate or a fixed slot that doesn't use the floor. You CANNOT decouple that type of sub.. I quit using them in the 80s.
SVS or JL or GR OB servo subs. Sell the REL and buy a pair to start with. IBs ported or passive radiators just NOT firing downward with an open bottom.. Kid stuff OP, pure kid stuff.. I been building bass enclosures for 45 years.. No one around me uses them they are the blight of the neighborhood. Makes everything vibrate.. Even the kids are decoupling their subs and mass loading the tops with springs too..
I am not a robot
Servos on subs are only necessary when you are asking drivers to do things they do not ordinarily do. It is a sign of poor or undersized drivers. Large well designed subwoofer drivers have no problem maintaining distortion levels below 0.5%. You run into higher distortion levels when you start asking drivers to take long excursions. If a driver is taking excursions greater than 1/2 X max than it is too small for the job. You can either use larger drivers or multiple drivers.
@mijostyn I want to keep everything as analog as I can, so DSP inline with everything else is not an option for me. I thought you were talking to make a crossover network among the subs.
Thank you for the suggestion
Sell the Rel?...Thats a really stupid idea!...You own the best selling subwoofer in Rels lineup and it is for a reason.Outside the reference #25 and the G2 you are there.I had the same issue with the same sub.I tweeked my room some and fix it a little...but when i bought another S510 thats when my system came alive..Yea you can go with another inferior subwoofer but at the end of the day thats exactly what you have.I would never take advise from someone who has no first hand experience with the product..cheers and happy tunes
@missioncoonery do you want it for free 🤣 no worries I will not sell the REL... 😂. I have a room with 3 G1 MK II, and another room with 4 #25s in my actual home.
In my house in the USA 2 510s will be tight that is why I was thinking something smaller and different response with the hope to help the room mode.
I am getting another 510.
