Hifi jim Posted February 23, 2010 Share Posted February 23, 2010 I agree with stormin. It's your amp, not your speakers. If you want that kind of bass and SPL, maybe look at something like a QSC amp. An amp with a high damping factor to control those twin woofers would help too. Quote Link to comment Share on other sites More sharing options...
SWL Posted February 23, 2010 Share Posted February 23, 2010 I agree as well but a 300 watt amp shouldn't make RF-7's snap from not enough power. Unless there is something wrong with the Emotiva or it's just a 300 watt amp with no balls? Quote Link to comment Share on other sites More sharing options...

Rlbol Posted February 24, 2010 Author Share Posted February 24, 2010 So if it is the amp What would be a better amp and why? Quote Link to comment Share on other sites More sharing options...
TxEvo8 Posted February 24, 2010 Share Posted February 24, 2010 I run an Anthem MCA2 by Sonic Frontiers for my RF7s, I crank it up all the way a lot and never had an issues whatsoever. Very nice, clean ss amp. I am actually looking for another one.. Quote Link to comment Share on other sites More sharing options...
SWL Posted February 24, 2010 Share Posted February 24, 2010 So if it is the amp What would be a better amp and why?The choices are endless as long as the amp is stable down to 2 ohms. From what I've heard about the Emotiva's they are supposed to work well with RF-7's.......which is making me wonder if something is wrong with that particular amp or something else in the chain isn't right. They shouldn't "snap" with a 300 watt amp if everything is functioning properly. Quote Link to comment Share on other sites More sharing options...
Southern Posted February 24, 2010 Share Posted February 24, 2010 Based on your signature of your equipment, I would recommend a minimum of a dedicated 20A breaker feeding your amps. If you don't have enough power feeding your amps may explain a 300 watt amp with no balls. Quote Link to comment Share on other sites More sharing options...

If you don't have enough power feeding your amps may explain a 300 watt amp with no balls. I have thought about that... I can drop a dedicated line easily. I have a buddy with glow rods, it's easy to do. I have everything on one 15 amp circuit. Maybe that's the problem. I know I have seen tests showing the XPA-2 making a clean 315 or 320 watts a channel by someone on one of these forums. Quote Link to comment Share on other sites More sharing options...
Fish Posted February 26, 2010 Share Posted February 26, 2010 There's nothing wrong with your amps,it sure as hell ain't runnin out of gas.I've had ATI,BK,Outlaw,Adcom etc......none with any more volume capability than the Emo's and none sounded any better,some much worse.

Coytee Posted February 26, 2010 Share Posted February 26, 2010 Having what seems to be 32,506 different plugs coming out of my single outlet, I'm installing four 20A circuits downstairs. I have had my breaker trip when the wife uses the vacume cleaner. (I realize that is a high drain) I was originally wanting to put two 20A circuits downstairs and add in a SurgeX protector but, they only have a single circuit 20A protector or a four circuit 20A protector so I'm sort of 'stuck' with the 4!! http://surgex.com/products/powerframe420.html It will be interesting to see if I notice anything different. Since I hope to have amps on one side of room, electronics on the other side of room I also have a mix of switched/unswitched outlets (switched on top, live on bottom).

stormin Posted February 26, 2010 Share Posted February 26, 2010 The popping his woofers are making at high volumes is clipping plain and simple. Its not the wall, light switch, breaker box, brand of amp or speakers. He is trying to get more than the amp is willing to give. Amplifier 101. You want more power buy a bigger amp!

SWL Posted February 26, 2010 Share Posted February 26, 2010 My Marantz 1070 integrated amp does the same thing on my KLF-20's. The 30watt amp sounds awesome until I turn it up past 10 o'clock and then it will start snapping. Horrible sounding, I might add. 30 watts of old school muscle can only go so far. As far as the Emotiva.....aren't these supposed to be high current workhorses with plenty of muscle? I've read nothing but good things about these amps and heard one with Cornwalls a couple weeks ago and it sounded great. Although it was only at medium volumes. Got a loose wire somewhere or something? Oh, and by the way RF-7's can handle 800 watts. Don't ask me how I know. [A] Quote Link to comment Share on other sites More sharing options...
Southern Posted February 28, 2010 Share Posted February 28, 2010 It could be the settings in your pre/pro. Did you increase the gain to the main speakers? Are you playing music from an MP3 player? Quote Link to comment Share on other sites More sharing options...
Vital Posted February 28, 2010 Share Posted February 28, 2010 I don't think it's the XPA-2. Here are the tests that were done on the amp. Could it be the Harman Kardon receiever I'm using as a pre-amp possibly? http://www.audioholics.com/reviews/amplifiers/emotiva-xpa-2/xpa-2-measurements Quote Link to comment Share on other sites More sharing options...

wstrickland1 Posted March 1, 2010 Share Posted March 1, 2010 The 7's are not good speakers for hip hop without a sub and bass management,maybe Cerwin Vega.Onkyo on 7's? Yikes,maybe HK in a pinch. Yikes is an understatement. I'm doing it right now with a tx-sr 805 temporarily and it is excruciating. Quote Link to comment Share on other sites More sharing options...
