Driver
1″ Aluminum Dome Tweeter:
- Vertically aligned tweeter and midrange improves horizontal axis polar response, with reduced lobing and comb filtering
- FEA-optimized diffuser for airy and unveiled presentation
- Aluminum dome delivers exceptional transient response and exceptional stiffness/mass ratio
4″ Midrange Drivers:
- Composite glass-fiber cone with excellent stiffness/mass ratio for high sensitivity and pistonic behavior beyond pass band
- Aluminum shorting ring to reduce gap inductance, lower distortion, and enhance high frequency response
- Cast aluminum basket to ensure precise alignment of critical components and additional heat-sinking capacity
- Vented voice coil former to minimize air compression artifacts at high drive levels
6.5″ Woofers:
- Composite glass-fiber cone with excellent stiffness/mass ratio for high sensitivity and pistonic behavior beyond pass band
- Aluminum shorting rings to reduce gap inductance and lower distortion
- Cast aluminum basket to ensure precise alignment of critical components and additional heat-sinking capacity
- Vented voice coil formers to minimize air compression artifacts at high drive levels
Crossover
- 3-way crossover with premium-grade capacitors, air-core inductors and heavy-trace printed circuit boards
- Midrange-to-tweeter crossover: 2.2 kHz
- Midrange-to-woofer crossover: 500 Hz
Cabinet
- Acoustically transparent and FEA optimized grilles, wedge-shaped front baffle and flush-mounted drivers all contribute to reduced edge diffraction and improved on-axis high frequency response
- FEA-optimized bracing reduces cabinet resonances
HiresAudioCentral.com Review: “Without question the Ultra is a monster speaker overall; in fact, it’s one of the most muscular centers I’ve heard…It delivers clean dialogue and vocals, has super-fast dynamics and enough midbass muscle to keep up with a THX-level theater system.”
