I can get Fli Underground and Fli Acid, which are similar entry level lines. So far my only experience with Fli Underground is a 2-channel amp I used to power tweeters. It's cheap but surprisingly good quality. I'm keeping it to re-use later bridged for a center channel setup. I couldn't justify spending more money when this FU360.2 amp will do just fine. My impression of the speakers and subwoofers is they're nothing special. It's a saturated market. I like the looks of the powered subwoofer enclosures, but like with many entry level brands the peak power ratings(which are meaningless) are splashed all over the product.
