Dylanl Posted September 10, 2009 Share Posted September 10, 2009 I have a pair of SVS ss 16-46 passive subs and I am driving them with a behringer EP4000 pro amp. I am using my DENON 4800 as a pre amp and sending the LFE signal to a clean box then to amp. How can I get the best out of these subs? Since I have no EQ will the LFE signal handle this? Any reccomendations on placement etc.? Quote Link to comment Share on other sites More sharing options...
EdmundGTP Posted September 10, 2009 Share Posted September 10, 2009 what is this "clean box" you speak of? Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted September 10, 2009 Share Posted September 10, 2009 what is this "clean box" you speak of? You can use it to go from pro style XLR's to RCA's. Most pro amps have XLR's and run at a different voltage than the home stuff. http://www.bhphotovideo.com/bnh/controller/home?O=cart_accessories&A=details&Q=&sku=288115&is=REG Quote Link to comment Share on other sites More sharing options...

I'm wondering if something like this would be usefull for what I'm doing over in my KSP thread. What exactly would be the benefit of using something like this instead of some simple XLR to RCA adapters like these. http://www.parts-express.com/pe/showdetl.cfm?Partnumber=240-438 Is the voltage from an RCA signal (i.e. sub signal from a receiver) significantly lower than what the amp would "like to see" coming in through the XLR inputs?

EdmundGTP Posted September 10, 2009 Share Posted September 10, 2009 Well this would go in between my receiver and my amplifier for the subs in my KSP towers. The sub output from my receiver doesn't appear to have a high enough voltage to work effectively with the amp I just got, and would also convert RCA inputs to Balanced XLR outputs. In addition, the MIC2200 would also serve as a high pass filter to avoid subsonic damage, and it can be used as a parametric EQ to aid in smoothing frequency response.

The art box. I also have the RCA to 1/4". At 1st I did not have enough gain but now I do. Also, I do have an SPL meter but I was thinking maybe more like a Behringer mic set up and some form of software. I also read where someone has a unit for 350.00 that will EQ your room and set up subs. Any idea on placement and should one sub be set 1st then the other or should both be placed at the listening position and the Sub woofer crwl begin??

Sounds like it would work but you could achieve the same results by setting your speakers to small in your receivers setup menu and using the receivers high pass filter in it's bass management. At that point all you'd have to buy would be a BFD for PEQ duties. They can be had for about a hundred dollars or so. Quote Link to comment Share on other sites More sharing options...

Dual subs can be used 2 different ways. If you co-locate them (put them next to each other) you could most likely expect 3 dB more output than you'd get if you placed them seperately around the room. Another benefit besides the additional output is that you're basically only setting up one sub and calibration is much easier due to the fact that you don't have to fight possible cancellation issues between subs. If you put the subs in different locations, you can potentially eliminate voids or nulls in your room and obtain more even bass over a larger area of the room than you could with two subs in one location. The down side is that it takes much more time and care in setting up. You have to pay a lot of attention to phase adjustment. You COULD put 2 subs in a room and have less output at your seated position than you have with just one sub. That would be a result of sub misplacement and your seated position in an area where the subs cancell each other out. I've had both set-ups in my living room and found plusses and minuses to both configurations. Quote Link to comment Share on other sites More sharing options...
Dylanl Posted September 11, 2009 Author Share Posted September 11, 2009 The art clean box I am finding needs modified to get to low fequencies. Ughhh, I need to find these caps asnd Radio shack doesnt have them. The ones I saw look more like crossover caps. Please see this link for mod then the second one for the testing. Let me know what you think http://www.subwoofer-builder.com/cleanbox/cleanbox.htm http://www.hometheatershack.com/forums/diy-subwoofers/5310-art-cleanbox-mod-thread.html Would Parts Express have these if so what would be the item # Quote Link to comment Share on other sites More sharing options...

CECAA850 Posted September 11, 2009 Share Posted September 11, 2009 Disclaimer, I don't own nor have I worked on a cleanbox. I've got 5 pro amps in my HT setup and didn't need one as my pre/pro accepts XLR's. Quote Link to comment Share on other sites More sharing options...

I'd read through the owners manual online but unfortunately their website doesnt have one available. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted September 11, 2009 Share Posted September 11, 2009 Not that I'm aware. That may eliminate the BFD as an option. I forgot you needed the extra gain on your receivers sub out signal. I keep getting you and the OP's systems mixed up. He has a Behringer amp which has a switch on the back to compensate for the pro/consumer voltage driver issue. At least my EP-2500 does.
