I just thought you guys would like to see "backup" for when the power goes out this summer. If I really want some "punch" I have another horn I can use with a crane about 48" long and 21" in diameter. Best listening position is on a ladder approximately 6 feet up. A side note is that the recordings sound almost identical on my 4412's with the exception that I hear the rumble much better on my JBL's! LOL Try it for yourself...
