Hello all, new to this forum. Was hoping for some USEFUL input on my project.
Here's the scoop,
I have 4 pairs of Pioneer DSS-9's that I will be combining into one gigantic pair this spring.
This will be a dedicated music system. I usually listen to rock.
My stereo includes:
DBX DX5 cd player, going into a cx-3 receiver.
The receiver's effects loop feeds a 400XG program route selector.
In the route selector, signal goes through a 3BX-DS, a 5BX-DS, then into a 14/10 EQ.
The outputs from the CX-3 get split, then run into a 120X-DS subharmonic synth/subwoofer crossover.
The 120X has it's own outputs to a subwoofer amp, and the other outputs feed a bank of BX-3 amps.
My original intention was to use one of the BX-3's to power my DIY subs, and power my DIY mains with two of the others.
The subs.... this is where I'm really looking for input.
I have 2 JL Audio 12W7's that I'm looking to use for this project.
I've browsed a lot of older threads, and would appreciate if everyone would stay on topic and not try to point me to any other subs of their preference. I also appreciate you not bashing JL.
Hate all you want, but the W7 is a pretty BA sub driver. I've had many, many systems of many brands, my ears tend to come back to JL. They sound more musical than most others to my ear.
My original intention was to go with 13W6v2s, but as luck would have it, I ended up with the pair of 12s for cheaper.
Ok, so now that we have it out of the way that I already HAVE (and am using) this pair of subs....
I originally wanted to power with the BX-3. When I hooked it up to them, they just don't have enough balls to power these power hungry subs. The amp is rated at 300-400W RMS depending on the literature you're looking at, and 900W "dynamic" power output.
This got me looking into other amps. The dayton audio 1000w got some bad press, and claims of it only putting out around 500w worried me, when a BASH 500w is cheaper.
I have bash 500w's built into my infinity IL-60's in my HT system, and they've been very potent performers.
The JL's are very power hungry though.... much more than the infinity subs.
So, I kept looking around. What I ended up with is a pair of sunfire true plate amps.
Not sure I'm going to go with these, the boards are anemic looking, and have the input sensing signal issue.
If you get them to come out of standby, they do seem to push the w7's pretty authoritatively.
Anyhow, my mains.... there will be 8 graphite 12's playing from 30-600hz.
My intent with the subs was to crossover low, and try to get essentially flat down to 20hz.
I have WinISD for a design program.
I was looking at around a 4.5 cube box, ported at 22hz, shows a pretty flat response.
This would be for EACH sub, as I'm intending on doing them as a stereo pair.
I called JL. They said don't do it, and kept trying to push me back into a small, sealed box.
Sealed boxes don't plot very flat very low. They kept trying to push me into the "gains" I'd get from a smaller box tuned higher, I think they totally didn't get the "I'm trying to get flat, down to 20hz" thru their heads.
Or the "size isn't really an issue for me", when it came to talking port length.
Has anyone experience with these in larger boxes, at home?
Does the driver have trouble playing in a box this big?
Maybe WinISD isn't telling me right? It shows the ideal curve I was hoping for, with the specs I listed.
Again, I'm not looking for alternative subs. ONLY BOX SUGGESTIONS.
I don't want to do sonotubes, these will end up needing to be aesthetically pleasing, but can be on the large side. I've had several W7s, many other JL subs, and many other brands. I'm happy with the performance I've seen from these subs.
I am open to alternative amp suggestions, however.
Wishing O audio still offered their 500w BASH plate, as the parametric EQ would be oh so nice (my infinities have it, and it can make a huge difference), but again, think the W7 needs more power.
Anyone have any useful input for me?
What about the sunfire plates/12w7 combo?
Would be greatly appreciated.
Thanks for reading!
