SQ H-15
 From StereoTimes Most Wanted Components of 2009: This was the first time that I've had a horn speaker in my system for an extended period of time and it certainly opened my eyes. The SQ-H15 was one of the biggest sounding speakers I've heard thanks in large part to its 15" woofers and space-filling horn tweeter. Couple them with a good tube amp like the Sound Quest SQ-88 tube integrated and prepare to be swept off your feet. The woofers controlled the bass like nothing I've heard while allowing the system to maintain top-to-bottom balance and musicality that is spacious, spacious, spacious. [Dave Thomas]

The Bass driver unit is a British-made coated paper cone driver featuring low distortion, superb sound quality and high endurance to humidity, assuring superb sonic performance even in wet and humid weather. Employing special technique in wiring coils helps increase reliability of the driver unit even under tough or at prolonged peak driving conditions. Power handling of this 7.7Kg in weight driver unit can reach as high as 400W.
The Tweeter is fitted with an over-sized magnet of diameter 170mm wide and is mounted with a titanium membrane. The Tweeter is embedded in an elongated horn structure of pyramid in shape helps derive a smooth response curve at the low end of highs, attaining a balance for the high frequency range. Both the tweeter and the bass unit are in a state of absolute phase accuracy.
Crossovers are of separate entities in design for handling highs and bass. Each of them is individually shielded in a separate enclosure inside the cabinet that can further enhance reduction in interference arising from moving current when the speaker is working. This crossover is designed to be of -18dB rollover so as to achieve minimal interference between highs and lows. Attention to details and more delicacy in design of crossover help getting rid of differential phasing, which helps gain a success in securing continuity over the entire frequency range. Internal connecting wires are of high grade OFC. Most of the capacitors used are selected high current flow CBB coaxial capacitors.
Manufactured with components of unsurpassed quality and high standard of craftsmanship, natural vocal, pure sound and exquisiteness in timbre in sound reproduction can be assured. Designed for critical audiophile, H-15 is truly amazing in its outstanding performance that nobody would disagree when brass instrument starts to play in an orchestral performance.
