If I just added another cab and powered 2 810's with 1 svt classic it would make everything louder? Figured it would just split the 300 watts it puts out between the 2 cabs. like not making anything louder really just making things stereo. And yeah I'm def gonna stay with the tubes now
It will convert your available power to sound more efficiently than your current 8 speakers.
Correction 2X the signal is 3DB.
However, the SVT and the 4PRO do not make enough power to WHOMP a pair of 810's to the level you think it needs to be whomped. You will actually sound better with just 1 cab.
When I refer to whomped is the sound it makes when its pushed, what makes up the AMPEG SOUND and stuff like that.
When hooking up a pair of 810's to my 4PRO; One. the power needs to be turned way too far up to drive the speakers, and, two, the speakers are unable to be driven hard enough to get the tone gotten by one cab per head.
If you look at all the BIG GUYS touring with more than 1 cab, they drive each cab with an amplifier.
This is also confirmed by Dino from AMPEG and this isn't just to sell more amps / cab, its reality.
When the cabs used 50 watt speakers, you'd drive two cabs, but not with 100 watt speakers.
But IF you are still determined to drive a pair, USE YOUR CL. Don't waste your time with a 4PRO, in the 2 channel mode it really doesn't make enough power @ 4 OHMS.
