Here is my latest sub project.
Dual 294 liter ported enclosures using a 6 inch port , an Acoustic Elegance AV15X and tuned to @ 15.5 hz.
These are being powered by a Behringer EP2500 in stereo mode and filtering is being handled by the Reckhorn B1.
The posted graph is taken from the listening position.

Hi Rightbrained.
I have a Reckhorn B1 too. To achieve that graph, are you boosting anywhere down low?

I am boosting 12 db at 40 or 50 Hz. I have the cut filter set at 16 Hz or so. I don't have a sound level meter and my response curve is not likely flat. So far my goal is loud lows and avoiding X mechanical. :hsd:

Very nice, what was the end cost for those beauties?

The drivers are $249.00 each at AE Speakers . With all the building materials and supplies I would estimate somehwhere around $725 or so , i really didnt keep up with it. Thankfully my wife likes to be immersed in the Theater experience so I get no grief from having big boxes in the living room.

In the graph above I have the B1 boosting around 50hz where I had a null at the listening postition.
That is very interesting. I wonder if that boost is raising the levels from say 35 to 70? That would explain why I can hear such an increase when turning it. In other words the boost could be affecting a relatively wide range of bass frequencies as opposed to a "narrow notch"?

Rightbrained,

I'm thinking I need a high pass filter for the AV15X project that I am starting, I read in one thread that you started with a mic2200 and then moved to a reckhorn b1. I have the EP2500 and haven't got the BFD yet, Is there any reason you chose to stick with the reckhorn unit instead of the mic2220. both have input gain and HPF so I'm not sure what the deciding factor should be if I want to order one.

Hi chrisg411 ,
I decided to give the Reckhorn unit a try because I sold the MIC2200 to my brother along with another sub and amp combo I built. I just wanted to try something different. The MIC2200 worked great and is a bit cheaper ,I would go with it unless you just want something with a small footprint.
On a different note , I just purchased a new Face Audio F1200TS and let me tell you something , that amp really woke up these AV15X's.

No not yet, I'm kinda procrasting/lurking and put up the typical newb questions and trying to soak it all up. I've started on my box, got the amp, new to all this I'll probably get the thread started once I make it a little further on my box and get motivated. I might just start it tonight. It's going to be a Max Easy Button Design by someone who's never done any of this before, never even touched a saw or router :dumbcrazy:

Well , if you find my first thread here it was one of NeoDan's easy buttons with a mal-x. That was my first DIY venture and it turned out pretty good.
Do yourself a favor if you are new to routers , buy yourself the jasper jig from parts express or something similar .It will pay for itself when you start cutting all those big holes,
