I first brought Infinity Kappas for My car afew years back - they were simply astounding. Anyone whos ever heard them would agree - and for that reason - I sourced a Pair of 363s (imported them to Aussie ) and coupled them up with 2 pairs of 163s, an Infinity Centre Speaker, and a Yamaha Powered sub. Its correct to say that they lack some bottom-end bass punch - but then, Im not into THUMP - Im more focused on clarity. The 363s are to My ears - exceptional. They are the last pair of speakers I will ever buy. I dont care if Youre a Professional reviewer, I dont care if You quote graphs - I know what I like and what pleases My ears. If Youre a Metaler - theyre not for You - however, if You want a sound that is crisp, sharp, defined and will carry a clean punch at volume - You cant beat them. Simply outstanding Speakers and amazing value. Enough said.
