That is impressive. For $10, you can't go wrong.

Somebody should clue MCM in about their website. I was getting catalogs from both Parts Express and MCM years ago, and considered them pretty much equal. Parts Express website kills MCM's website though-heck, you can barely even see pictures of the speakers. All I saw was a listing with order numbers.
Excessive parameters

I have the opposite problem:

I bought these Selenium 15" woofers and am working with them in WinISD but the program wants a parameter: Le

The manufacturer lists:
Le at Fs
Le @ 1 khz
Le @ 20 kz

These are in mH if that helps . So since Win ISD only wants one Le which one do I use?
