Folks, who would you recommend as a good 6th order designer? I have had a couple of 4th orders before, but never tried a 6th order and my understanding is if the design isnít right these things donít perform well at all. I am looking at the MCM 8Ē subs and want to do 4 subs in an isobaric 6th order. I would be giving them about 700/800rms from an older Rockford 800a2. Again, who would you recommend for this?

BTW, here are the subs Iím looking at.
MCM Audio Select 8'' High Excursion Woofer - 120W RMS 4ohm | 55-2421 (552421) | MCM Audio Select (http://www.mcmelectronics.com/product/MCM-AUDIO-SELECT-55-2421-/55-2421#reviews)

Nobody does or knows anyone that does good 6th order designs?

What are your goals with this box and why the idea of running isobaric?

I'd imagine Buck could design one. But off topic: I ran one of those bad boys in an Autotuba design for over a year and it's a hell of a little sub.

A guy on another forum said the same thing about the autotuba. I had never heard of it and googled the design. How many watts did you run to your Autotuba? I get the impression that most people arent running more than 2 or 3 hundred watts based on the sub they pick.

Couple of the reasons for the isobaric. With 4 I basically can end up with a 4ohm load which is way better for my amp(old school and doesnt really do 2 ohm with my electrical). I also had a isobaric sealed back in the day and loved it. I also am trying to cut as much space as possible and the MCM isnt really a high motor force sub so iso should work well.

That makes sense. I can model a parallel tuned sixth for you but I don't do cut sheets. So if you can take volumes and port dimensions and make your own box I'll gladly model it for you.

I was running around 150W RMS to it, but I feel like it could handle more. My amp I had hooked to it would only output 150W RMS @ 4 Ohm. Honestly for what it is it gets down and gets pretty loud. I mean it's a $30 8" Sub.
