I am going to dip my toes in a digital solution soon. I got rid of my JL subwoofers (with apologue high-pass) and ordered new subs (JTR RS1). This time around I am going to try the MiniDSP SHD for sub integration. Not sure the MiniDSP will be good enough for a long term solution for me (clean enough? Maybe?) but it will let me try different filters and what not (has its own PEQs, and Dirac too). If I like the solution I will try something more highend as money allows. The SHD is limited to two subs and I think I would like to try 4 at some point
My room is pretty large especially with the back doors open to other rooms. The room is effectively 42’ long and 26’ wide with everything open. So I don’t fight room nodes as much as others. I just like the slam of subs (no speaker can touch it) and want to digitally align them more or less.
I don’t see anyone using JTR stuff for music so it should be interesting (they have a trial period, -shipping). I just picked based on the measurements, impressive extension, overhead, and low group delay. For their measurements they were pretty “cheap”.
