Hunty 0 Posted July 14, 2005 Report Share Posted July 14, 2005 Hello Hope you can help as I am confused! I am thinking of buying these Carlsboro Speakers: 250W RMS (continuous) 500W (program) each 8 Ohm Frequency response 60Hz - 20kHz What amp will I need ? Thanks Andrew Link to post Share on other sites
DJ Marky Marc 0 Posted July 14, 2005 Report Share Posted July 14, 2005 In an ideal world a amp that can put out 500watts rms into 8ohms.... however any amp thats rated above 250watts into 8 ohms is ok.... think about the future get a quality amp and/or one that will handle your system expanding ..... <a href="http://www.djassociates.org"><img src="http://www.djassociates.org/anims/compres_banner.gif" alt="Join the DJ Associates Disc Jockey Association" border="0" width="468" height="60"></a> Link to post Share on other sites
DiscoStudio 0 Posted July 15, 2005 Report Share Posted July 15, 2005 Personally I would go for one of the Numark Dimension Series: Numark Dimension Amplifiers <a href="http://www.djassociates.org"><img src="http://www.djassociates.org/anims/compres_banner.gif" alt="Join the DJ Associates Disc Jockey Association" border="0" width="468" height="60"></a> Link to post Share on other sites
stevie 0 Posted July 30, 2005 Report Share Posted July 30, 2005 http://www.dj-forum.co.uk/html//emoticons/042.gif get the best amp you can afford dont buy the cheep big output 1's as they dont cut it! i have a 500 watt rms each side drivin 250 watts rms speakers and it sounds sweet,the speakers work hard at times but with the amp havin the power all works well. tight bass and a clear top end. not sayin brands as dont think we is allowed,but you gets what you pay for.

DJ Marky Marc 0 Posted July 30, 2005 Report Share Posted July 30, 2005 QUOTE Just to clarify,that is for the whole amp and not per channel.Correct? Nope thats per channel in stereo.... My speakers are 500RMS each, I use an amp that puts out 960watts RMS per Channel, as you can see the 960w RMS is as close to the "IDEAL WORLD" 1000w RMS.... Also the Damping Factor on larger AMP tends to be a lot better and they give better sound quality... <a href="http://www.djassociates.org"><img src="http://www.djassociates.org/anims/compres_banner.gif" alt="Join the DJ Associates Disc Jockey Association" border="0" width="468" height="60"></a> Link to post Share on other sites
norty303 0 Posted July 30, 2005 Report Share Posted July 30, 2005 We're going to go through this whole thing again i can see but i'll also chime in and say you should be looking at an amp that can supply 1.5 to 2 times the rms rating of the speaker at the stated impedance DIY plans and pro audio related technical discussions www.speakerplans.com/forum Link to post Share on other sites

A 500watt amp would delivery 500watts (ish) but it would be thrashing itself and just waiting to send some nasty DC bits into your speakers. Safer therefore to use say a 900watts rms amp, which will simply be "doing just nicely thanks" when being asked to deliver 500watts rms. (again, attentuators down, and compressor/limiter in-line too). What I think is crazy is when someone slaps a 1000watt amp, UNattenuated, onto a 500watt speaker, with their mixer outputing off into the red and wondering why their speaker cones ended up 40ft away, sunny-side down in the blue cheese dip on the buffet table:D then doing the Monday morning phone'round for re-coning services.

High Fidelity 0 Posted July 30, 2005 Report Share Posted July 30, 2005 (edited) QUOTE I'm lost.So you are putting 960w rms@8 ohm into 500w rms speakers No!! http://www.dj-forum.co.uk/html//emoticons/fear.gif You have an amp that is capable of supplying more than the speakers rating, but you don't give the speakers more than they can handle. The idea is that you never have to run the amp flat out. Obviously you have to use common sense and don't try to push what the amp is capable of supplying into the speakers or it's bye bye speakers. I normally work on the principle of having an amp that can deliver about 1 third more power than the speakers, so the amp never gets turned up above 2 thirds of it's power, thus keeping it well within it's range so it never has to work too hard, which in turn means no distortion.

Digital discos 0 Posted July 30, 2005 Report Share Posted July 30, 2005 The RMS testing is not done with a musical signal. I believe it's done with something similar to a sine wave, which is an intense wave. Most cabs can handle more with recorded music. a 500w speaker should easily handle 700w long term, it's when you start being stupid like 1200w etc etc. Also a bigger amp gives you headroom.

cookiecat 0 Posted July 30, 2005 Report Share Posted July 30, 2005 I still think you could get in trouble pushing 960w into 500 Something witty goes here.. Link to post Share on other sites
DJ Marky Marc 0 Posted July 30, 2005 Report Share Posted July 30, 2005 the speakers will handle 500 rms all day long.. 1000w program and 2000w short term peak.. I never want to be putting 2k into them but i also never want to get to 500w rms and see my amp clip, clipping is the cause of 98% of speaker damage... basicly when your amp clips you get a square wave rather than the ups and downs of a normal signal... the flat bits at the top equate to pure DC voltage from your amp, this heats up the voice coils and then they cook... so if you see a clip light then you run the risk of doing damage. now my amp can give me all 500w with out going near to clipping.. it also can give me near to the 1000w program power if lets say a recording has an extra loud bit.. this head room works in two ways... first i never see a clip light so no cooked coils.. second, it sounds better becuase the amp is not over worked, and it has the Damping factor needed to controll the speakers... so as i said before in an ideal world you would have this head room in your amp. so when i put together any sound system for any event I always go for as close to twice the RMS power of the speaker as possible and then add compressor/limmitor to the setup to make sure its all under control... the problem is big amps with good quality parts and decent output figures are not cheep... <a href="http://www.djassociates.org"><img src="http://www.djassociates.org/anims/compres_banner.gif" alt="Join the DJ Associates Disc Jockey Association" border="0" width="468" height="60"></a> Link to post Share on other sites
