I am having major issues finding an affordable pipe to use as a port for my sub!

The dimensions are 6" x 22".
Obviously I would buy 6" x 2' if someone can find it relatively cheap.

Thanks!

6" diameter sonotube would do the job, check local building supply and hardware stores.

Would a 6" Precision Port Tube work in this application? 6" tube that opens up to 8". This is probable more expensive than buying a sonotube from the hardware store.

my neighbor is a plumber so i just asked him and he gave me a piece for free

Okay I will start looking for that Mike.

Also, what would be some really cheap, but efficient, methods of lining the inside of the box? 23x36 inches on the inside of the cabinet.

 

[Mike P.]

Egg crate foam from Walmart, it's sold as a mattress pad.

Will do. Been looking nonstop for 6" form tube. Its next to impossible to find. I have found tons of 8" and up tube, but no 6" =/ , Lowes and Home Depot only carry 8"+.

What if I changed my sub from a 6" diameter port tube to an 8"... would that increase performance and quality?

 

[Mike P.]

An 8" diameter tube would need to be 41" long. Another option is two 4 " diameter ports 20.5" long each.

Gotcha. I think I am going to stick to 6", going to check some plumbing companies around town.

I found mine at a local piping distribution company, that is also a client of mine. Search the yellow pages in your area.

Also search the dumbster at your local mechanical contractors. You might find a section to meet your needs for free.

Mike, or anyone else, I am now figuring out the best type of wood for my subwoofer. I really don't want to use MDF because of the weight issue.

What kind of alternatives would Cherry, Oak, and Maple wood provide? Thanks

 

[Mike P.]

Whatever kind of plywood you get make sure it's "void free". Birch is a popular void free type.

 

[Shicks18]

Gotcha. I heard that those types of wood resonate n such. The workshop thats going to be used building the subwoofer has tons of that wood laying around. Would I need to add another piece of bracing in the cabinet if I use Oak,Maple, or Cherry plywood?

 

[Mike P.]

Your bracing is fine, just make sure whatever you use is void free.

Mike -- I know I have been hammering you with questions lately, but I have yet another question... this time about an amp.

I did some searching and found an MCM Electronics 300 Watt Plate Amp for $110 shipped with coupons. I was wondering if it was any good and do just as well as the Bash? If not, I will be more than happy spending another $40 on the Bash 300.

There is also a link with the schematics posted.

As long as it has a HPF around 18 hz or so it would be fine. You'll have to contact MCM to verify it has a HPF and at what frequency.
