My experience adding subwoofers to 2 channel

My Kappa 9 speakers are rated to 29hz and they sound pretty good in my 18x24 room...powered by McIntosh mc1.25 amps...l was looking for another layer of bass to enhance the sound..my first experiment l took my SVS pb16 ultras from my theater room and tried them first...it sounded terrible,didn't blend well..couldn't hear a difference until you turned in up then it rattled the room apart........my final experiment worked..l used 4 Velodyne minivee subwoofers(1000 watt rms class D sealed 8 in.) and after hours of calibration l hit it......lve got the bass response that exeeded my expectations. ....l should have done this along time ago....can anybody tell me of another subwoofer that may work even better?

I want to add my subwoofer to my stereo system, I run the DAC directly into my amplifier. The Dac has a volume control, and the amplifier is balanced with DB25 connectors with pass-through.

Has anyone had experience here with an output decoupling transformer and summing two channels?

Oh and if you really want to clean up your sub sound, put springs under it.
Yes for real, it stops the vibrations going into the substrate and back up into everything you don't want to vibrate, including the sub woofer that created the vibration.
Townshend Audio in the UK have plenty of scientific style videos showing the benefits of seismic isolation.
