I recently purchased a pair of Kenwood KVS400 speakers and I'm quite satisfied with their performance. They offer good value for the price. With dual woofers, they can produce decent bass without the need for a subwoofer. Though vintage, they have a simplistic design and decent aesthetics. I'm currently using them with my 100W Ch DIY amplifier, but I feel that these speakers could benefit from more power to reach their maximum potential. While I believe the original crossover is functioning properly, I'm unsure about its age or the production year of these speakers.
