I have a pretty hefty bandpass box with two 10"s that I'm currently using for my sub. It's a box mostly meant for car audio competitions but right now it's filling in for HT duty until I get something else built. It has two 4Ω drivers and I can wire them however I need to (they are arranged in push/pull). Anyhow, I was powering it with an A500 (source from pre-amp outputs of a Denon 2307CI). I knew this box could handle a lot more power so I grabbed an EP2500. So now the chain goes Denon -> RCA mono -> 1/4 TSR -> EP2500. It seems I had to crank the gain on the sub output to +12dB (max) to get the sub to some good output at about 12 o'clock gain on the EP2500. Probably obvious to most on here, but it doesn't sound that great.
So here goes my questions:
1. I've heard of people using a cleanbox to "step up" the pre-amp signal to pro sound levels. I've read a lot and there seems to be pros and cons (read where a lot of people got them, then removed them later). Would something like this help? Or is it no better than jacking up the gain on the receiver?
2. I've heard of people using a BFD. I've also read a lot about these, but honestly don't really understand what it does. Does it also step up the gain? If I was to get one, what exactly would I do with it straight out of the box?
3. I've heard of people using an EQ (with several different models given). Without hooking up a mic and graphing everything (which I've never done before) I can definitely tell there are gaps in the curve. I.e. I loaded up the star wars II opening scene with the big chrome B2-bomber-looking ship coming down and one part would be booming to the point of bringing down the house (as it should be :twisted: ) but another part would be pretty disappointing. Would an EQ help me level this out, and solve the gain problems from the consumer -> pro equipment? Would an EQ also replace the BFD or cleanbox (kind of an all in one)?
4. Is there some other box I should be aware of that I didn't list?
5. Should I wire the subs a certain way for better performance? As said they are two 4Ω 10"s in a push/pull config in a bandpass box (box is here if you want to see it). I suppose my options are:
a. One driver straight to each channel on the amp and run in parallel mode.
b. Parallel the drivers for a 2Ω load and just run off one amp channel (read that 2Ω -> bridged mono is a big nono on this amp)
6. I can set my sub crossover frequency in my Denon, should I just set that as high as possible and let one of these boxes do the rest, or what should I set it at?
Sorry if any of these questions are just rehashes of old threads. I did read through a lot of them, and being extremely new to these three pieces of equipment, there was lots of stuff over my head in those threads. Plus I figured for some newbie who comes along after me he'll have all three in the same thread .
