Prime Towers: Pillars of Performance—Stereo to Cinema
As the primary source of full spectrum sound, the Prime Towers anchor the listening experience. Their combination of both accuracy and dynamics elevate the experience of your movies and the nuances of your music. The voicing of the towers’ multiple drivers match and seamlessly meld with the other Prime or Ultra speakers in your system. The result: they transport you to the center of the action—be it mosh pit or jet fighter cockpit. Dialogue and vocals are clear and true. Bass grooves and bomb blasts will rock the room. With Prime towers’ twin 6.5 inch woofers in each tower, you don’t need a stand-alone subwoofer if space won’t allow. (Should you have the room—and want the additional depth and dimension a dedicated subwoofer provides—Prime towers pair well with several SVS subwoofers, like the award-winning SB-1000.)
SVS Sweats The Details - You Hear Perfect Sound
With a smooth aluminum dome tweeter, dedicated midrange driver and dual long-throw woofers, the Prime Tower effortlessly cranks out clean, dynamic and powerful sound.
The innovative and sophisticated 3.5-way crossover has different crossover points for each woofer to eliminate lobing in the vertical axis and improve total radiated sound power. Translation – awesome bass response and a smooth, seamless transition to the midrange.
SVS took the 3.5-way crossover concept a step further – each woofer has a dedicated and completely separate internal compartment with its own custom port tuning frequency. The result is bass you need to hear in person to fully appreciate.
Similarly, the 4.5” midrange driver is mounted in its own dedicated and completely sealed compartment to ensure a smooth, precise and clear midrange free from standing wave coloration.
All this tech is packed into a handsome and sleek cabinet available in premium-grade piano gloss black or handsome black ash finish. And for that touch of class – the Prime Tower has the same upscale metal spiked screw-in feet as our flagship Ultra Tower.

Driver Array and Technical Highlights::
1" aluminum dome tweeter: FEA-optimized diffuser delivers airy and unveiled presentation. Aluminum dome for exceptional transient response. 4.5" midrange driver: Polypropylene cone for excellent stiffness/mass ratio and pistonic behavior. Aluminum shorting ring to reduce gap inductance, lower distortion, and enhance high frequency response. Cast ABS-fiberglass composite basket ensures precision component alignment and excellent thermal transfer. Vented voice coil former minimizes air compression artifacts. Dual 6.5" woofers: Long stroke motor ans suspension for high output. Polypropylene cone for excellent stiffness/mass ratio and pistonic behavior. Aluminum shorting ring to reduce gap inductance, lower distortion, and enhance high frequency response. Cast ABS-fiberglass composite basket ensures precision component alignment and excellent thermal transfer. Vented voice coil former minimizes air compression artifacts.
SoundMatch Crossover Network::
3.5-way crossover with premium-grade capacitors, air-core inductors and heavy-trace printed circuit boards. Tapered woofer array optimizes the transition to the midrange driver and reduces vertical axis lobing. Midrange-to-tweeter crossover: 2.1 kHz (12 dB/octave slopes). Top woofer (Combined Woofer) to midrange crossover frequency: 350 Hz (12 dB/octave slopes). Bottom woofer low pass frequency: 165 Hz (customized filter Q and slope).
Cabinet Construction Technical Highlights::
Separate sealed midrange enclosure shifts standing waves beyond the driver pass band, improving sound quality. Separate woofer enclosures with optimized port tuning frequencies for smooth and accurate bass response. Acoustically transparent and FEA optimized grilles minimize diffraction. Chamfered front baffle and flush-mounted drivers reduce edge diffraction and improved on-axis high frequency response. FEA-optimized cabinet and bracing eliminates resonances.
Frequency Response and Electro-Acoustic Data::
Rated bandwidth: 30 Hz-25 kHz (+/-3 dB). Nominal impedance: 8 ohms. Sensitivity: 87 dB (2.83V @ 1 meter full-space, 300-3kHz). Recommended amplifier power: 20-250 watts.
