need help with a waterproof subwoofer box

[TXwakesurfer]

I want to put some new subs in my mastercraft because the ones in it now are falling apart. (well the wood/carpet box is rotting and coming apart...subs are fine)

 

Anyways I found this company that makes solid clear acrylic sub boxes.

 

invisible-enclosures.com

 

Has anyone ever used an acrylic sub box?

- How do they sound?

- How durable are they?

Nautiques came with fiberglass woofer enclosures. Occasionally see them for sale on EvilPay.

TRUST me on this I did car audio for years: Get Waxed concrete tube from Home Depot/Lowes etc that will fit your sub +2" all the way around. Use the tube to trace a plywood end plate to mount your speaker and to section it in the middle if you use one on each end of one large tube. Paint end peices after fit to speaker. Silicon glue them in place and shoot dry wall screws in from the outside. Then use construction adhesive caulk to glue high grade marine carpet to cover the tube and make some wooden feet to keep it from rolling if it is to be placed horizontally. Run your wires and mount your speakers. Be sure to port tube to speaker manufacturers specs some don't port. THUNDER BASS in little space.....

I used the same 15" sub in a professionally built 3/4" thick plexi enclousure in two boats. Worked great!

The Nautique enclosure is terrible unless you spend some time modifying it. It's essentially an unsealed box. We've fiberglassed MDF floors in them to create a sealed enclosure and THEN they sound decent with that Polk Momo 12 sub.
