Preliminary plans - Opti1232d

I know nothing about them and couldn't nail them down with a quick google search

Can you link me a 5"D 31"L aero port?

I like the idea of slotted because -

- easy to incorporate with the enclosure

- free (my 4x8 will leave me alot of scrap)

Problems - wouldn't be able to put it on plane with the woofer w/o a bend

4" port should work fine.

use the calculator on www.psp-inc.com to get length.

according to winISD the port area of a 4" port would result in pretty significant port noise. The aero may have worked fine, but I decided to go with what I'm familiar with.

I went with a 9x2 slot which gives me 33% more port area than a 4" round.

So far I've only tested it with my $75 pyramid (eminence) sub. Once on my 100w home receiver/amp which surprisingly didn't sound 1/2 bad, and once on my wife's Vibe 430 on a pair of bridged channels.

With the vibe at around 300w this sub/enclosure seriously pounds.

It should be interesting once I get it installed in my 'Tour with the opti1000.1D at 400w.

Assuming that all comes together I'll be ordering the Opti1232D as a Christmas gift, and dropping the 1000.1 to 1 ohm for 1000w rms.

I hope my trunk holds together.

Nice. With aeros, you can cut down on approx 50% of required port area because of the flare.
