A perfectly balanced, seamlessly integrated high end 5.1 sub/sat system based on KEF’s new 4.25” Uni-Q driver array and a superlative matching subwoofer, the new E305 home theatre system outperforms the competition by filling the room with a spacious, exquisitely detailed and compellingly natural soundscape that captures all the magic of the original performance.
The E305 system is designed to deliver exceptional bass performance, with the sub seamlessly integrated within the rest of the system, so it sounds like five full-range loudspeakers. The frequency and phase response of the sub and satellites are carefully matched to smoothen the transition, so you can’t hear where the satellite stops and the sub starts.
With a large, powerful motor system driving a long throw 8-inch cone, low frequency reproduction remains composed and unerringly accurate, even at high volume. Based on a Linkwitz Transform circuit to minimise any signal group-delay that would otherwise muddy the bass, the on-board pre-amp assures noticeably cleaner and more accurate low frequency reproduction.
A closed-box design, the E-2 subwoofer delivers agile extended bass response without overhang – fast, punchy and well defined. Like the satellites, the cabinet borrows damping technologies from the LS50 to avoid resonance and secondary radiation to ensure tight, clean and immaculately controlled bass.
