  • QSC Powerlight 3.4 for two Sealed UM18-22

    Hi Guys,

    Got a bit of a dilemma I’m struggling to resolve. I have two UM18’s on the way and am going to have them sealed in boxes just over 5 cuft, and placed in opposed corners of my room (6m x 3.6m). 

    I was planning to get a berry NX6000 as so many recommend, however I have an option of 2nd hand QSC Powerlight amps.

    Do you think it’d be better to get one 3.4 or two 1.8’s, costs being equal? Or would one 1.8 be enough to drive two sealed UM18’s? I’m wanting to touch the low teens in freq response, but probably have relatively low listing levels compared to many of the guys on AVS. Currently running a single PB1000 with the volume at 1 o’clock.

    Currently feeling that the 3.4 is the best choice just to have gobs of headroom even if it’s the more expensive choice. Hopefully a fan mod wouldn’t be too tricky as I expect it to be a bit noisy, been run as a PA amp for prob 20 years.

    I already have a Mini DSP 2×4 HD and UMIK1.
