kg4guy Posted September 15, 2011 Share Posted September 15, 2011 I'm planning to build another pair of MWM's and was wondering how to run these as they will be under 2 ohms per channel ? Quote Link to comment Share on other sites More sharing options...
djk Posted September 16, 2011 Share Posted September 16, 2011 How many drivers per channel are you planning on? Is it for hi-fi or PA? Quote Link to comment Share on other sites More sharing options...
kg4guy Posted September 17, 2011 Author Share Posted September 17, 2011 Two per channel maybe use it for PA. I'm running it with 3 Crown. xti 1000 amps now with one driver per channel on the LF also have a new Peavey IPR 1600. Quote Link to comment Share on other sites More sharing options...
djk Posted September 17, 2011 Share Posted September 17, 2011 Maybe a QSC RMX1850HD would be what you want, I bought an almost new one recently for less than $400 (including shipping). The RMX1850HD has the same heatsink, fans, and number of outputs as the RMX2450, but is optimized for 900W/2Ω continuous. How is that Peavey IPR 1600 when you slam it?

kg4guy Posted September 17, 2011 Author Share Posted September 17, 2011 The Peavey I just hooked up in place of the Crown xti 1000 on the LF haven't had a chance to hit it hard yet but at moderate levels has more than the xti . I'll push it tomorrow or the next day I've been converting all the 1/4 jacks to speakons on the Peavey stack I just got the FH-1's the MB-2's and the MF1-X's.

Guest " " Posted September 18, 2011 Share Posted September 18, 2011 Multi driver MWM's and MCM's use k-46's instead of k-43's. K-46's are 8 ohms per driver and k-43's are 4 ohms. Quote Link to comment Share on other sites More sharing options...
kg4guy Posted September 18, 2011 Author Share Posted September 18, 2011 Is that on the new models as the older MWM's had K-43's Quote Link to comment Share on other sites More sharing options...

Well I pushed the Peavey today and man for a 7 lbs this is a great amp and at $269. a great deal at 800 watts per channel at 2 ohms I pushed it to the point that the XTi's fans would have come on it stayed cool even though the Peaveys amps fan is on all the time but wasn't warm to the touch at all the Crown Xti gets warm to the touch when running the MWM's.

mark1101 Posted September 19, 2011 Share Posted September 19, 2011 I have been happy running my MWMs with a QSC PLX2 1104. I have a PLX2 1804 for my subs...........and I really like these amps. Clean and quiet. Plenty of power. I had a pair of Crown XTI-1000.........and we run the 2000s at church. They hiss like a mother! Sorry, those are just not very good cheap amps. I couldn't live with them at all and got rid of them. If you are not using the DSP, then there is much better out there used for the same money.

Guest " " Posted September 19, 2011 Share Posted September 19, 2011 Is that on the new models as the older MWM's had K-43's Go to your pdf under impedeance, go to MWM, go to each driver.....it says 8 ohms. A k-46 is an 8 ohm version of the cast frame k-43. Quote Link to comment Share on other sites More sharing options...

You are correct they do hiss I have ben checking all my cables and connections thinking something was wrong. I think I will look into the QSC amps.

mark1101 Posted September 20, 2011 Share Posted September 20, 2011 Crown XTI..........It's the A/D & D/A.............it's poorly done and causes the unit to amplify a lot noise. I know a lot of people use these (a lot), because they are cost effective, have built-in DSP, and say CROWN on them. So I don't mean to piss people off..............but they are not up to the snuff of the Crown name. When I go to church I can hear the hiss all the way at the back of the church (I run the board). There is nothing I can do..........Frankly it sucks and is embarassing. It's disruptive to the service as well. It's that audible. They'll be on the shelf as soon as our next music donation comes in. We will be going to QSC amps. Audible noise in a system has always been my pet peave. I know it doesn't bother some folks. I'm just too picky I guess.

ClaudeJ1 Posted September 20, 2011 Share Posted September 20, 2011 OK, I can't resist this one: Do you throw a "hissy fit" when your hear it? LOL. Quote Link to comment Share on other sites More sharing options...

Sure wish I knew this about the Crown Xti's before I purchased them. Quote Link to comment Share on other sites More sharing options...
Panacea Engineering Posted September 20, 2011 Share Posted September 20, 2011 I'm sorry....I must be missing out on something. I have five XTI 1000's (all bought at the same time and what a deal it was.....!) They have driven MCM 1900's four way with HISM's and also three sets of KP 362/682 (2 over1) active through two DriveRack 260's. I'm just not hearing this Hiss....................maybe I'm deaf after spending 15 years as a starter at a drag strip, but on my systems the Hiss isn't there. Granted, they are cheap but they have done the job for me. They have driven these systems for the last three years, without a problem. Come to Woodruff, SC next May and you can certainly hear them......[] YOUR milage may vary............................. W. C. Quote Link to comment Share on other sites More sharing options...
kg4guy Posted September 20, 2011 Author Share Posted September 20, 2011 The hiss is there but the system is still amazing I really enjoy it and it's great for sides in my garage theater . I am going to order Canare cables to see if that helps also. Quote Link to comment Share on other sites More sharing options...
Panacea Engineering Posted September 20, 2011 Share Posted September 20, 2011 I certainly don't think the cables are the issue.....If it was me, I would look further into the source of the material you are playing. JMO, W. C. Quote Link to comment Share on other sites More sharing options...
kg4guy Posted September 20, 2011 Author Share Posted September 20, 2011 I was going to get Canare cables anyway just between all my amps and crossover and EQ and I guess the hiss isn't a really big deal would be nice if it wasn't there I'll work it out[] Quote Link to comment Share on other sites More sharing options...
