Landon,

Hmmm...I think yours is a different series.

My 310 HO model I have has a single side-firing 10" woofer, two 5 1/4" mids and a 1" soft-dome tweeter. All of the HO (High Output) models have the soft-dome tweeters. This line was 'updated' with titanium tweeters but I don't recall any of them having two woofers.

Does this one look similar to yours?
