Anyone using active subwoofers? We are currently developing a line level subwoofer isolation adapter. Planning to put it in a discrete power supply chassis size. Just assembled the first test PCB now, will need to test it for results. Big improvements to move the subwoofer off the DAC outputs, that parasitic load comes at too high of a performance cost. Even with our previous gen isolators. This should see great improvements overall!
A work in progress, will post updates as we move the project along. Currently designed to connect with our current speaker lugs. This will allow banana plugs or spades to connect to your speaker or amp end of your system.
I have a subwoofer out of my Cello Audio Suite 2 The Sub-Isolator, to output on 2 Cello Duet and JL AUDIO Fathom 113 V2. Am I a good candidate I would be happy to experiment I am in the South of France.
I have a select with two power supplies and Femto 33
Would the new Sub Adapter Project be better than the Sub-Isolator?
@Erik , yes. This will have a pair of speaker cables as the incoming line, with a single XLR output to the sub. One unit will be needed for each channel if you have two subwoofers.
@Alinous , welcome to the forum! Yes, this will be a great application for your system. We will keep updates going here, but I expect it would help quite noticeably. We think this is a much better approach than our previous design. Will keep you posted.
My most challenging matter is to match sub with main speakers and adding active crossover might destroy the advance of hiend DAC. Would you recommend any possible way to xover to system which uses msb dac? I’m using premier dac and connect 2 sub to line out on integrated amp.
Thank you.
