I've been lurking around this site now for a couple of months and have decided to enter the DIY speaker building world. I have built a couple of enclosures for automotive applications but never for home use. I have a JL Audio 12w6 laying around from a previous automotive system that I would like to use for my first project. The woofer has dual 6 ohm voice coils and I need an amp that can handle the 3 ohm load. I see the behringer amps are highly recommened on this site and was looking at purchasing one for this build. I will eventually replace this subwoofer and would like to have an amplifier that can be used for the upgrade. I guess what I'm asking is, will these two components work together? Can the seperate channels from the amp be connected to the seperate voice coils so the amp is seeing a 6 ohm load on each channel? Or, can the amp be bridged and handle the 3 ohm load? Any advice would be much appreciated.

I have Just acquired the same speaker...
and was thinking of using it too.
I tried to model it in WinSD(I am New to it).
but it stated it would do 19.44hz in a ported enclosure around 7 sq.ft.
I have a 150w plate amp though, not the Ep2500
so I look forward to hearing what you end up doing.- Bottom

After thinking it through some more, I think I will purchase the ep1500 and bridge the amp. However, I think running the voice coils in series for a total of 12 ohms would probably work best. I am unsure about running seperate channels to each voice coil.- Bottom

I have been looking at a subsonic filter for this build as well. I checked out the ed eq.2 as well as the Behringer feedback destroyers. Will the behringer units act as a subsonic filter and if so which one would be the best option. If there are better option, please advise......- Bottom

well, i have decided to go with the BEHRINGER EP1500 and the Elemental Designs eQ.2. The eonclosure is well on its way to being completed. I am just waiting for the Jasper router jig and a few parts. I understand that subwoofers in a ported enclosure will unload if it sees frequencies below the tuned level. How do I accurately set the subsonic filter to the lowest htz safe for this subwoofer? The dial on the eQ.2 doesn't have small increments to go by.- Bottom

The sub is done and it ROCKS!!!!!!
Well, I finally finished the project and tweaked it until it sounds awesome. I originally purchased this speaker 7 years ago and used it in a car audio set-up. It sounded great in a selaed enclosure but it just didn't give me the output that I wanted. It sat around for a couple of years until I got the itch to start upgrading my home theater system. I modeled this speaker with Winisd and started buidling. The enclosure has internal dimensions of 24 x 24 x 22.5 for a total of 7.5 ft3. Less the woofer and port displacement comes out just over the 7 ft3 recommended by Winisd. It is tuned to 19 hz. When I first hooked everything up it sounded like crap.... But, after tinkering with it for awhile, all I can say is WOW! I actually find myself being startled during action scenes due to the impact that is felt. Music also sounds very good with this sub, too. All I can say now is that the fever has overtaken me and I will be building center, mains, and surrounds as soon as I can decide on one design.- Bottom
