Whats the best tuning and Vol and shape. Vented Box Design

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?

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

 

[phemps 10+ year member]

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

 

[y2kbugger 10+ year member]

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

 

[phemps 10+ year member]

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

dodecahedron is the best shape for SQ //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

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...
