Björn Fröberg Posted December 30, 2004 Share Posted December 30, 2004 We all know you can buy a hifi subwoofer amp to attach to your home-built sub to make it an active subwoofer. What I've been looking for, but haven't found, is an amp-module like that but for full-range speakers. Basically a 2 channel amp with an active (adjustable) crossover that you can attach to your home-buildt monitors, thus making them active monitors. Do you guys know if there are amps like this on the market, and where I could get some information about them? - Bob Freebird A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools. -Douglas Adams Link to comment Share on other sites More sharing options...
philbo_Tangent Posted December 31, 2004 Share Posted December 31, 2004 If I understand you correctly - what you what is a stereo power amp. The world is full of them... Crown, Hafler, QSC, lots of people make them. Phil Tangent Studios http://artists.iuma.com/IUMA/Bands/Tangent2/ Link to comment Share on other sites More sharing options...
John Sayers Posted December 31, 2004 Share Posted December 31, 2004 I think he means an amp with an electronic crossover in it. cheers john Studio Design Forum Studios Under Construction Home Page Link to comment Share on other sites More sharing options...
philbo_Tangent Posted December 31, 2004 Share Posted December 31, 2004 Ah, I see. Well, add a cross-over unit to the stereo amp, and you've got it. (One extra rack space)... But no, I don't know of any all-in-one unit that would do the job. Maybe you could order it as a replacement part (for example, ask Mackie to sell you the electronic guts from an HR824 speaker).

offramp Posted December 31, 2004 Share Posted December 31, 2004 try www.partsexpress.com I've upped my standards; now, up yours. Link to comment Share on other sites More sharing options...
dj jud Posted December 31, 2004 Share Posted December 31, 2004 What you're gonna need is a two way, stereo electronic crossover, plus a small (25-100) watt stereo amp for the tweeters, and a larger (75-200) watt stereo amp for the woofers. This is exactly what live sound people have been doing for years, i.e. biamping. It won't be cheap. Try Carvin, they've got everything you need. Parts express might have stuff like that, but I think they come in a little high on the price. You must really love your speakers, because you could buy a whole active monitoring system for what it's gonna cost you to do this. And, you get an engineered product that you know is consistent. You may need to do some RTA analysis in a proper test room to get that thing balanced right. Link to comment Share on other sites More sharing options...

Two stereo amps and a crossover indeed isn't cheap, and I wouldn't go that far. I like the speakers, (they could need a bit of tweaking though) but they aren't that good that I would spend more money on them than I could get a pair of Genelec 1030's or 1031's for. Actually I did some analysing with SIA Smaart, and compared one of my speakers to a Genelec 1030A (in a normal room), and if you believe the results (which I'm not sure I can) is that my speakers had a flatter response than the Genelec. - Bob Freebird A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools. -Douglas Adams Link to comment Share on other sites More sharing options...

But the problem with ordering a replacement part is that they are made for the speakers in question, so they don't have an adjustable crossover. BTW, I checked with partsexpress, but didn't find what I was looking for. I knew this was gonna be a long shot, but I thought I'd ask anyway, 'cause you never know these days. - Bob Freebird A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools. -Douglas Adams Link to comment Share on other sites More sharing options...
