Can anyone provide info on selection of a driver for El Pipe-O, especially what parameters are critical, how to determine pipe size, etc.
In particular, would a 12" car subwoofer work well in this design
I see there is some (but not much) discussion in El Pipe-O is up at [url]www.passdiy.com[/URL]

Nic

Nice drivers, those lambdas -- they are not going out of business, just mutating so they can survive.
Idealy you would like a driver with 0.5<Qt<1.0. And the bigger the Vas of the driver, the bigger the pipe you will need for optimum performance (el pipo would perform better with a larger pipe than it has...)

I ordered a set of the TD15S-LE drivers before the price increase, and I wasn't impressed. I'll take a peerless XLS over them.
One was damaged in shipment and I've had a heaping helping of really bad customer service from them. I just mailed them back last week for a refund.

Hello Everyone,
I have some questions concerning drivers for use in a EL Pipe-O.I
am planning to use 4- Dayton Quatro 8's. Parts Express #295-545
in a compound push- pull set-up. I am trying to figure out the enclosure vb (.80 or .40 ), PVC pipe 8" dia. 30" long and stuffed at
.785 lbs/ft3.Does this sound right?
Sincerely,
Cambe

Even with only 1 driver per pipe, your line sounds awefully small.
Martin King has just released his 1st alignment tables. You could use these to get a more optimum el pipe-o. http://www.quarter-wave.com/

Turn off the plug-in in your browser and just download the pdf... the web server he is on may not support viewing of a pdf inside your browser.

Some of the "pdf" files are quite large. The download time can be 15 - 30 minutes depending on which file you select. If you try letting the download continue for a longer period of time and still have no luck please let me know which file you are interested in and I will e-mail it directly.
Hope that helps,
