Well, I received my MJ-18 last week and I am excited. I will be using the same size enclosure that Mark used on his Sonotube sub which is 8.8 cu ft. I've used lots of mdf in the past so the main enclosure will be made out of 13ply oak plywood with mdf bracing. I'm hoping to get started this weekend on the enclosure. By the way, how do I post pics? I don't see an attachment manager.

I forgot to mention that I hooked the Bash300 amp up to the MJ-18 and let it sit on the floor. I played some music selections with heavy bass and wow. I turned the speakers down and cranked up the bass knob, the floor was shaking and the speaker was thumping away. Maybe that's why my wife doesn't want me to work on the subwoofer, she knows it's going to blow the house apart when its done!

Well, I bought a Bash300 amp because I sold me Bash500 last month. I also bought a 6" sonotube from Lowes. I have acoustic foam, rubber feet for the base, mdf, plywood and lots of glue. Hmmm what do I need? Oh yeah, I need my wife to stop pouting so I can go outside in the freezing weather and cut some braces and wood in my unheated shop! Oh well, I guess she needs some attention too (then again I spent all day yesterday with the family).

Thanks for the advice guys. 18Hz it is.

Mark, What do you think about changing the tuning frequency? Below are WinISD for 18Hz(light color) and 21Hz(darker color) tuning. Any thoughts?

Here's the WinISD and my kids holding the driver. I hope to start building on Friday!

My MJ-18 is en route and will be placed in a 8.8 cu ft enclosure made out of 13ply plywood. I am curious if the 18" proto will fit in as a replacement when it comes in?
