for Dual Type R's
I want to be more conservative with SPL, and more twords SQ (as much as a vented can be so)

It's a second Gen Ford Probe, I can get back to you dimensions but its a pretty spacious trunk(width and depth, might be a little short)

I Listen to Techno and dance and electronic music, and also rap. and rock. What kind of bass does techno like?

I'm eventually going to need a box designed. whats the going rate around here?

4 cubes @ 32 - 36 Hz would do nicely for a pair of Type R 12"s...

Can any one make me plans for these, what is the usual cost
? Also what does a dump dump dump drum/techno beat sound like with a port. i know porteds are good for a synth-basstone, but what bout a beat where it more just like a single excursion(i think)

4.4 cuft
35 hz

i'd probably need some re enforcement allthread in there right?

how do i choose between high and tuning?

what about ports facing different ways?

will higher hz and/or smaller volume give a tighter response?

will higher hz and/or smaller volume give a tighter response?

after reading, it seems the opposite is true. can there be too much SA on the port, or is more better?

too much surface in a port will make the box peak high in the tuned region. way too big and you may get unloading issues

i remember seeing a rule for how much one should have now that you mention that, anyone know it?

try to stay around 12 to 14 sq inch per cube net volume generally

dodecahedron is the best shape for SQ :fyi:

Also what about bass drums? Do they act like a single excursion?(with no definite tone) how does consideration for this type of beat affect the design(not want them to sound like a puff of air through a tube? Does a sub sonic filter kill these considerably?

Kick drums should be the only drum heard through your subs. A sub sonic filter will not affect the reproduction of a kick drum.

Has anyone actually built a dodecahedron box? That would be a ***** to build! LOL...

While this is, as far as I know, the first 12 sided, inverted-******-diaphram speaker
