Thanks for the info, will be handy as I jump into my upgrade to a more SQ-like setup.

I don't have any additional info on SQ setups in particular, I'm just now at the point where I can really go SQ

This is gonna be a really long post, but here is a lot of what I use.

All of A. Neville Thiele and Richard Small's research papers:

Fecupe2001's thread from here on his SPL gains and testing:

http://www.stevemeadedesigns.com/board/topic/98191-spl-gains-updates-page-30-routing-the-port/

Covers the basics of almost anything audio.

Flaring PVC ports and a lot more info on it.

For calculating port area and length these are some great formulas:

If you want to get into the real "nitty gritty" parts of it check out this, any further look into the sources he sites:


JBL's system design reference manual. Not car audio based, but it directly relates to car audio.

MY FAVORITE:
Sound physics The man who wrote this is not too computer "savvy", but was an engineer for NASA's Jet Propulsion Labs for 35 years. He has two "Table of Contents".
