[QUOTE="Vinny D'Agostino, post: 19074, member: 112"] Re: Need SUB help... A few things, First I have NO DSP, so setting a delay for the tops is not possible. I don't have any fancy metering things, I just have my ears. But, I did go play with the QRX subs a little bit with what I have. I took just (1) QRX218 and I ran the RMX4050HD in bridge mode for power, this on paper should be 4000w @ 4ohms. I know this is way to much power for this sub so I depended on what is left of my hearing to listen for signs of stress from the sub. It made a big improvement on the performance from what my ears tell me. The sub certainly had more output and hit harder, as it should seeing how it was beeing powered with 2500w more then it was used to. Here is the thing, I don't really want to sell what I have, it's all paid for and makes me some nice money. I do want better performance from the QRX subs, and I want the best way to achieve this. I have been looking at replacing the amplifiers with something more effecient and higher output. Should I look for (too me) big dollar amps like the QSC PL380 & Crown MA-I series, this way I would not have to bridge any amplifiers into my cabs....or, is it worth while to go with something like the new Crown Drive core series or Peavey IPR series running them bridged and finaly getting a DSP. I am thinking an amplifier in the 2500w @ 4ohm range would be about right for the subs, as that is there program rating. And, I probably should move out of the stone age and get a DSP either in the amps or a seperate unit. [/QUOTE]
