...so can you get more efficient airflow by ADDING baffles between a driver and the port in a ported design? would anyone like to explain an acoustic labrynth--

i THINK this would only work for 1 single tone...

this also came up when fighting over the most free flowing exhaust and how Flowmaster's baffled design can actually have greater flow than the straight through pipes-- but.. uh.. i need enlightening.

Only would work for a single tone. Though In car audio it is really not worth the trouble.

The idea behind the baffles is to create higher air pressure, which in turn will act as a spring.
By the way, Yamaha motorcycle division had quite abit of input to Yamaha's patented "YST" technology in their sub-woofers(home audio). The principals are the same, avoid air turbulance in the chamber. (round off any corners)

Well, Dukk has his "ports" of call and I have my Transmission-"line" of duty *LOL*.
But I'll keep my mouth "sealed" about the issue.
