Worth it

Just installed them and only tested since still waiting for 1 part to complete my setup. 1 did show up damaged but Marshall and the Sweetwater team rushed me out a replacement to get it all squared away. Will be more testing soon but so far I love them and don't regret buying through Sweetwater. A+ rating for Marshall and the Sweetwater team.

Eminence 18

Excellent speaker! I put one in an Acoustic 371 bass cabinet and wow! I rattled pictures off the wall! The tone is back for this cabinet! Very pleased!
Rated 5/5

Sigma pro

I recently swapped out all 8 18inch and replaced them sith some sigma pro. I was blown away by the difference in the way my cabinets sound .... subs are really deep and am playing reggae music. Reggae has to have deep bass. Am really satisfied and is saving up to replace some more cabinets.
