Hi all ok for sometime now i have been having issues with my Eden 212 XLT box just cant get a sound that cuts through. Anyway i also have a Trace Elliott 150w combo which has 1 10 in a bin type enclosure like a BLX80 anyway i suddenly though hmm 10's good, own power source why not slave the amps together use the GK to power the 212 as a sub and run the combo as a mid range? So both are running at 8 ohms GK=180 watts and combo about 100 So after some advice on here ran a cable from Effect send to input of Trace and plugged bass into the GK switch on both and hope it works. Oh baby! it works great used this setup on a gig the other night and cut like a knife lovely thick punchy sound with plenty of lows and the tweeter in 12's makes up for the slightly boxy sound of the combo i'm sure i could get this same sound using no doubt a smaller portable setup but since i already have it all for the mo it will do just fine. looks a bit kooky but it works!
