Members twostone Posted October 1, 2011 Members Share Posted October 1, 2011 Need to know since Peavey released their new IPR4500 amp. How it would match up to a pair of Yorkville LS608 subs ? 1 sub per side @ 8 ohms Also can the subs handle crowd of 200-400 ppl. Christian rock band. My ex drummer looking to add passive subs that won't break his back or bank account.Figured I ask here first before I tell him. Thanks Link to comment Share on other sites More sharing options...
Members RoadRanger Posted October 1, 2011 Members Share Posted October 1, 2011 An IPR3000 is safe for them subs - the IPR4500 not-so-much. One pair of those subs are good for 150+. I'd not try to cover more than 250 with a single pair. Link to comment Share on other sites More sharing options...

The IRP4500 puts out 775 wpc into 8 ohms. If you're trying to cover 400 with one pair you'll be driving the snot out of them and you could get away with that with an IPR3000 but the IPR4500 would be a bit much. OTOH if you get two pairs the IPR4500 would probably be OK. Link to comment Share on other sites More sharing options...
Members Vinny D Posted October 1, 2011 Members Share Posted October 1, 2011 I ran LS608's for a few years powering them with a RMX4050hd, either (1) per channel or (2) per channel depending on the system.Never had a single issue with that much power going to them (800w @ 8ohms), and IMO the driver in the 608 can take a ton of abuse without failing.The biggest issue with the 608 is getting them to stay still on the floor, they are a very light box and also not very well braced internally so you get a lot of box flexing.This causes drinks that get placed on top of them to vibrate off with ease and also will make you chase them across the floor from them vibrating away....unless you put a heavy cabinet on top of them....(2) subs will be maxed out to do a 200 person room, they also take a bit of EQ'ing to get a decent thump out of them.....a nice 6db boost around 60hz helps that box out alot.I always crossed them over with my high packs at 90hz.(RCF ART325i).If there are 50hz limiters in the IPR amps I would not have a problem driving them with a 4500, if there isn't any limiters in those amps spend the money on a amp that has them.

Members agedhorse Posted October 1, 2011 Members Share Posted October 1, 2011 Depends on how lucky your friend feels. IMO, the 4500 is too big for the average user. Link to comment Share on other sites More sharing options...
Members jlb Posted October 1, 2011 Members Share Posted October 1, 2011 No HPF's on these amps is a little disappointing. On the other hand it will be good for the recone business. Just think of all the people getting ready to buy the 4500 or even better the 6000 so they can bridge them into their pair of 718's. Link to comment Share on other sites More sharing options...

Members RoadRanger Posted October 1, 2011 Members Share Posted October 1, 2011 Really? I have new found respect for Peavey. Is this a new step towards idiot proofing passive systems?Mostly it saves them the cost of the switch. If you ask on their forum they'll still tell you how to bridge them . If they gave a @#$% about idiot proofing them they'd have HPF's for subs or left out the crappy 100hz "crossover" . OTOH the 100Hz HPF's are handy for monitors .

Members stangconv Posted October 1, 2011 Members Share Posted October 1, 2011 Hmmm same question as OP, but with Yorkville LS1004's instead. Currently using a 3000.... But have dsp and have then set to 80hz to 35hz Link to comment Share on other sites More sharing options...

Members twostone Posted October 1, 2011 Author Members Share Posted October 1, 2011 Okay the IPR don't have limiters and basically to much amp for the subs.So which QSC GX5 or GX7 ? and keep in mind it's a church band no collapse a lung. Lots of blue hair not sleeves of tattoos and body piercing type of crowd. Link to comment Share on other sites More sharing options...

Members stangconv Posted October 1, 2011 Members Share Posted October 1, 2011 So, what's the "issue" you're seeing that needs fixing? Just want to have them properly matched. Running dual 15 tops with a 3000 but I think the subs could take a little more. Link to comment Share on other sites More sharing options...

Members agedhorse Posted October 2, 2011 Members Share Posted October 2, 2011 Aged can you explain a little how the DDT limiting works in these amps. Basic process of most amp clip limiters is that the output is compared with the input and when the output stops increasing relative to the input, a corrective error signal is sent to a gain reduction cell that momentatily reduces the amp's gain. There are 2 or 3 common ways to do the detection but the basic concept is the same. Link to comment Share on other sites More sharing options...
