RE: Two Scott 299s to one pair
Posted by PakProtector on January 5, 2017 at 07:06:27:
If you're going to bridge instead of parallel connect, you will need a phase splitter to feed each existing channel signals that are 180-degrees out of phase. A small transformer like the UTC A-18 does a fair job of this, and can run step up or step down.
They will tolerate signal level well below 20 cps at levels quite adequate for the application. Then you hook your 8R speaker between left and right 4R output taps, and ignore the ground.
cheers,
