Hello,
Would it be recommended to run the 4.5 in parallel mode to power 2 EV QRx218s's? Does anybody have positive/negative experiences using the pld series on sub duty?

Thanks,

Corey

Be patient. Mac will unlock your other thread eventually.
Short answer: They work fine.

I'd highly recommend getting two of the PLD4.5s and using 3 channels for each sub and 1 channel for each top. This is how I power my system. I have different speakers but they have similar power ratings. If one amp dies, you can use the other to power the whole system to get you by.

Sorry, I thought that thread would be dead for not following the rules. Initially I was thinking about running a plx3102 bridged to each sub, then a 3602 stereo to the tops. Most of what I have been reading suggests bridging the plx amps to 4 ohms for sub work is not suggested. That got me looking at the pld line of amps and wondering if they are better suited to subs. I really like the flexibility of the pld 4.5. I would probably start with using 1 in parallel to power the subs and use my existing rmx2450 to power the tops until I found another 4.5. I also like that I could power all 4 speakers at 1200 wpc from the 4.5 in a pinch.

Thanks

Who's recommending against bridging the PLX amps for sub duty?

We run PL380s in stereo for mains, and currently have 3 PLX3602s, each one bridged, running a total of six EAW SB180R subs (4-ohms per amp, 2-subs per amp) at our bigger/outdoor shows and things work great. The PLX3602s have been totally reliable and hit well. I'll eventually upgrade to a another PL380, but only when I make the shift to some TH-118s or Orbit Shifters.

I just acquired a PLD4.5 for monitor duty as well. Probably overkill... but, I like the ability of having it as a back-up as well.
