How to check for an air leak?

[Mr. Mom]

Hey there! Did a search but came up empty-handed.

Just finished a Jack 15 w/out tweets. Coupla questions:
--How do I know if I have an air leak?
--How does one go about checking for an air leak?

I can't believe I'd have one after the over use of adhesive and use of gasket material. But just thought I'd check to be sure.

Thanks in advance!!

30hz at low power. Listen for a chuffing noise. It will be readily apparent if you have one.

Don't have the technology to produce a 30hz frequency. Something a little less....Ummm, a little less....primitive I could do??

Run this on your computer. Take the headphone output to just about anything that will provide some amplification, an old stereo for instance. Free!

Never thought to check on-line for a download!

Thanks!

BTW, Leland: I'm the guy that bought the Jack 15 flat pack from you recently. If this cab does well this weekend then I'll be getting another (with the speaker).
