Hi everyone hope you're well. Just checking if anyone used the new sublime acoustics K 231 active crossover.

I have been using my Oppo 105d for bass management in a very audiophile 2.1 system but the bass is really not that great.

So I'm looking for something new, if anyone's a real master in the bass category maybe share what's working for you, Iam interested.
 
Bass quality is almost always limited by room acoustics, or the quality of the subwoofers. Before you spend $600 on a new crossover solution let us see measurements of your current system. If you don't have a measurement mic that should be your first purchase, best $80 you will spend on audio.

Yes I have acoustic testing gear with ANSI and ISO certified filters with a class 2 mic.

I'll put some measurements up but more importantly the crossover filters between the oppo and the subwoofer don't work, it's very audible.

A better investment world be Oppo 105D->Optical->miniDSP 2x4HD/DDRC-24/Flex->Power Amp and subwoofer.

A digital crossover enables more precise, easier to implement sub integration.
