Indyjeep Posted December 23, 2006 Share Posted December 23, 2006 Ok, this is an xmas gift to me from my parents. Spending max of $300. Need ideas. Its a dual 4-ohm sub. Max of 500 watts I believe. Looked at Behringer, Crown, QSC.....ideas?? Ordering tonight. Parents just told me. Haha... Quote Link to comment Share on other sites More sharing options...
Indyjeep Posted December 24, 2006 Author Share Posted December 24, 2006 Nevermind, lol Got the Behringer EP1500.....hmmm this is gonna be nice[] Quote Link to comment Share on other sites More sharing options...
DrWho Posted December 24, 2006 Share Posted December 24, 2006 What kind of cabinet are you putting it in? Quote Link to comment Share on other sites More sharing options...
Indyjeep Posted December 24, 2006 Author Share Posted December 24, 2006 8 cu. ft enclosure, tuned to about 19-20 hz......... Quote Link to comment Share on other sites More sharing options...
DrWho Posted December 24, 2006 Share Posted December 24, 2006 Ah, a real sub [Y] Seems I'm a bit late to the party, but you should seriously consider implementing amplification with some filtering (at the very least a high pass filter to control the excursion below the tuning point). Seeing as you're going with a pro amp, your best option would be some kind of processing to go in between the amp and the receiver - which should also work well in converting impedance (unless the Behringer already has line-level inputs). When you crank the system, you'll realize some peakiness in the 40Hz region - hopefully your room will have a null in this region. An alternative would be to implement a slight amount of EQ reducing the output in that region. Anyways, I think this amplifier would be a perfect match for your situation:http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=300-808 But I guess I mention it for anyone else considering a similar application. So how important is the signal processing? I just got finished running a subwoofer workshop and we did a side-by-side comparison with a pair of Assassin 12" drivers powered by 1000W of pro-amp versus a single Assassin 12" powered with a plate amp with EQ. The single system without a doubt had much lower distortion at all output levels - simply because subharmonic information wasn't causing the driver to bottom out (on notes you would never hear or feel anyway). Without EQ your configuration should yield a clean 107 dB, but with EQ should yield a clean 118dB...that's quite a bit of difference [] Quote Link to comment Share on other sites More sharing options...
Indyjeep Posted December 24, 2006 Author Share Posted December 24, 2006 Well with the money I get for xmas I was going to invest in one of the FeedbackDestroyers....what yathink? Quote Link to comment Share on other sites More sharing options...
DrWho Posted December 24, 2006 Share Posted December 24, 2006 Never used one before, but a lot of people seem to really enjoy it: http://www.hometheatershack.com/forums/bfd-rew-forum/ Quote Link to comment Share on other sites More sharing options...
Indyjeep Posted December 24, 2006 Author Share Posted December 24, 2006 So one of the BFD from Behringer would act as a Parametric EQ? From reading thats what I gather from it. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted December 24, 2006 Share Posted December 24, 2006 Yes, a BFD will give you 12 individual bands of PEQ. Quote Link to comment Share on other sites More sharing options...
Indyjeep Posted December 26, 2006 Author Share Posted December 26, 2006 Awesome, got $50 for Christmas. And once payday hits I'll order the Behringer. Any certain model thats better than others? Quote Link to comment Share on other sites More sharing options...

Indyjeep Posted December 27, 2006 Author Share Posted December 27, 2006 So the EP1500 came in today.....it is a beast, Ill post pics later of the insides when I get home from work. Can't wait til I get home to play with it. Heheh [] Quote Link to comment Share on other sites More sharing options...
Indyjeep Posted December 27, 2006 Author Share Posted December 27, 2006 Just curious, since Im using an AV Reciever, Yamaha HTR-5750 to be exact, How would I hook up the DSP 1124 in the the Behringer EP1500 with the AV receiver? Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted December 28, 2006 Share Posted December 28, 2006 Go from the receivers sub out connection to the BFD's input. Then run an RCA from the BFD to the amp. I believe you'll need an adapter to hook the cable to the amp like this: http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=091-1010 Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted December 28, 2006 Share Posted December 28, 2006 Pay close attention to the dip switches on the back of the amp. Use the diagram in the owners manual to set the switches and disregard the verbage on the amp itself. Quote Link to comment Share on other sites More sharing options...
Indyjeep Posted December 28, 2006 Author Share Posted December 28, 2006 One more question, would it be better if I ran a Y-cable out of the Yamaha and into than basically a stereo signal into the DSP and Amp? Quote Link to comment Share on other sites More sharing options...
brennyE Posted December 29, 2006 Share Posted December 29, 2006 I saw this topics and thought I had to chime in because about 2 weeks ago I purchased the same amp you are going to use for subwoofer duty also [H] Trust me you are going to love the EP1500! even though I blew up my old 15" sub with it, I still love the thing (it was my fault) Both the behringer Euro power Amps have in built high passes, selectable at 30hz and 60hz (or turned off) but I suppose this is useless for you because of how low you are porting it......... A bit of fore warning though.....you will probably have to run the behringer with the gain pretty high to be able to squeeze out all the power......from my understanding most home audio brands (like your Yamaha and my HK) have lower voltage outputs than Pro Audio sources.....I have heard of people using Onkyo receivers with some pro audio gear and getting very lousy performance, supposedly because of the very low powered out put signal. I think you are going to have a very nice subwoofer system indeed [] Quote Link to comment Share on other sites More sharing options...
DrWho Posted December 29, 2006 Share Posted December 29, 2006 You will get a 6dB gain in output from your reciever going that route - which is arguably a good thing considering your impedance mismatch. Quote Link to comment Share on other sites More sharing options...
Indyjeep Posted December 29, 2006 Author Share Posted December 29, 2006 You will get a 6dB gain in output from your reciever going that route - which is arguably a good thing considering your impedance mismatch. That is if I use a Y-cable correct? So that might make up for the low input signal..... Quote Link to comment Share on other sites More sharing options...
