Default What Type Of Enclousure For Dual 15" Earthquakes?

Hi there,

I was looking forward for some suggestions on what kind of enclosure should I build for a pair of 15" earthquake balls for home use, any suggestions welcome.


Thanx,

Tony

I take it your previous post didn't help much?http://www.diyaudio.com/forums/showt...threadid=22802

Could you maybe provide a link to these drivers, or the specs on them? Iíve never heard of them and an Internet search doesnít turn much up.

*edit*
I've turned up a little.

Might try at the source for your box needs.

Also don't underestimate the easy and usefulness of winISD Especially for a sub box.

I did an enclousure according to their website but it does'nt seem to be as good as it should be. i don't mind trying out transmission line or any other suggestions.


Thanx,

Tony.

Default 5" diameter 13" long port

Tony,

The Earthquake looks like it was designed for very high SPLs at 40Hz. THe 2.5 cu ft "lowest frequency" design on the webpage looks like the best for music. You may want to try a 5" diameter, 13" long port to tune down a few Hz.

You can also consider sealing the box and building a Linkwitz transform to create a controlled Q lower frequency bass boost. This configuration should yield lower and "tighter" bass, but it requires 2x more power.

Music 15" woofers often have lower Mms(100-150 grams), a low Fs near 20 Hz, Qts near 0.35, and are put into much larger cabinets to efficiently reach low freq with good transients.
