I was quite surprised at how much output the EP400 had compared to the EP350.

No doubt you can get a lot more output with a properly designed 15" driver, but my guess is that the EP400 has a long throw 10" driver in it. The long and short of it is that it depends entirely on the driver design.

Nope, it's an 8".

Interesting. I thought it was a 10.

I always exaggerate too.

Sooner or later, someone will figure out that it's a toilet paper tube. THEN what will you have to say for yourself? Hmmmm?

It's biodegradeable?

I wasn't exaggerating, I was stretching. Its part of my new exercise routine.

Then your weight plates have twine through 'em?
