3.5-Way Driver Design: The SVS Ultra Tower speaker utilizes
a 3-way driver design with a 1" aluminum dome tweeter, two 6.5" composite
glass-fiber midrange drivers, and dual 8" cone woofers for a powerful and
convincing audio experience from the highest frequencies to the lowest bass
- 1" Dome Tweeter: The 1" aluminum dome tweeter's excellent
stiffness-to-mass ratio and integrated FEA-optimized diffuser create an
exceptional transient response with an airy and unveiled presentation.
You'll hear incredible resolution, absolute transparency, and crisp,
- Two 6.5" Midrange Drivers: The two 6.5" midrange drivers feature
a composite glass-fiber cone with excellent stiffness/mass ratio for high
sensitivity and excellent pistonic behavior. Aluminum shorting rings are
used to reduce gap inductance, lower distortion, and enhance high frequency
response. The cast aluminum baskets ensure precise alignment of critical
components and additional heat-sinking capacity. The vented voice coil
formers minimize air compression artifacts at high output levels.
- Dual 8" Cone Woofers: Dual-opposing 8" woofers
housed in a bass reflex enclosure at the base of the speaker deliver deep,
articulate base. The sweeping side panels of the tower speaker are also
non-parallel, so each of the 8" woofers fire in different directions to fill
the room with bass. The dual 8" cone woofers utilize a long stroke motor and
suspension for high output. Aluminum shorting rings are used to reduce gap
inductance and lower distortion. The vented voice coil formers minimize are
compression artifacts at high output levels.
Note: The dual-opposing 8" woofers may result in a phase warning during
an AV receiver auto-setup process; this is normal. Simply double-check to make
sure the speaker wire is connected correctly.
SoundMatch Crossover Design: The SVS Ultra Tower speaker features a
3.5-way SoundMatch crossover with premium-grade capacitors, air-core inductors, and
heavy-trace printed circuit boards. The top-midrange-to-tweeter crossover is set
at 2kHz, the bottom midrange taper frequency is set a 950Hz, while the dual
midrange-to-woofer crossover is set at 160Hz. The precise tuning of the
SoundMatch Crossover also ensures balanced output throughout the frequency
Performance Driven Cabinet Design: Every feature of the
Ultra Tower loudspeaker's cabinet was designed with a sonic purpose in mind.
- FEA-Optimized: The SVS Ultra Tower speaker uses non-parallel
cabinet panels to reduce axial standing waves within the cabinet, reducing
frequency response coloration. FEA-optimized bracing, 1" thick midrange/tweeter
baffles and 1.5" thick woofer baffles eliminate structural resonances and
ensures the cabinet remains acoustically inert for uncolored response even at
the highest output levels. In addition, acoustically transparent and FEA-optimized
grilles, a wedge-shaped front baffle, and flush-mounted drivers all contribute
to reduced edge diffraction and improved on-axis high frequency response.
- Divided Chambers: The SVS Ultra Tower speaker's enclosure is
divided into two sections. The top half of the cabinet which contains the tweeter
and midrange drivers is sealed for crisp, accurate, and detailed high and
midrange frequencies. The bottom half of the cabinet which houses the two
opposing woofers features a rear-firing 3.5" (diameter) wide-flared port for greater
efficiency, as well as bigger and deeper bass response. A foam bass port is
included to "tame" the bass output if its too "boomy" due to room placement.
Dual Gold-Plated Binding Posts: The SVS Ultra Tower speaker
has two sets of gold-plated binding posts connected by jumper-straps. The gold-plated
binding posts will accept bare wire (up to 10AWG), pin connectors, spade
connectors, & banana plugs (single only). Using the dual posts, you can bi-wire
or bi-amp the speaker. Bi-wiring or bi-amping the speaker provides improved bass
& treble performance.
- Bi-Wiring: Bi-wiring can provide noticeable
improvements in the overall transparency of your loudspeakers. Run separate
speaker wires to the low & high frequency drivers from a single amplifier
(the upper set of binding posts are for the high frequency drivers; the
lower set of binding posts are for the low frequency drivers).
- Bi-Amping: Bi-amping allows you to use separate
amplifiers for the high & low frequency sections of your loudspeaker for
greater dynamic range & lower distortion. We recommend that your separate
amplifiers have identical gain to preserve the speaker's voicing balance.
Note: If you decide to bi-wire or bi-amp, you must remove the
jumper-straps between the terminal posts (failure to do this could result in damage to
your amplifier and loudspeakers).
Elastomer & Spike Feet: The Ultra Tower speaker comes
packaged with two sets of feet options that allow optimal placement on a variety
of floor substrates. The elastomer isolation feet that come pre-installed on the
Ultra Tower are perfect for hardwood, tile, laminate, and vinyl flooring. The
elastomer isolation feet can be removed and replaced with the included threaded
metal spikes that are designed for carpeted floors. If you want to use the metal
spikes on hardwood, tile, laminate, or vinyl flooring, then use the included
protective discs under the spike feet to protect your floors. Both sets of feet
are threaded to allow easy leveling of the Ultra Tower if it should stand on an

- Dimensions w/ Spikes & Discs: 13.9375" (w) x

Note: The Ultra Tower speaker should not be used without one type of
Placement: A pair of SVS Ultra Tower speakers should be placed 30° off-axis, relative to the primary
seating position. Toeing-in the loudspeakers 5-10°
may improve imaging. Placing the loudspeakers closer to room boundaries will
increase the bass response, while moving the loudspeakers away from boundaries
and corners will reduce the bass response.
Note: Dedicated room treatments like
absorbers, diffusers, and bass traps (sold separately - see Accessories tab) can
greatly improve the sound quality of any listening environment.
Ultra Series: Whether playing a multi-layered soundtrack of
a movie or a 2ch soundtrack of a music file, the SVS Ultra Series loudspeakers
deliver a powerful and convincing audio experience. From the drivers to the
crossover and cabinet, each component is painstakingly engineered and tested to
achieve breathtaking realism. Countless design innovations and world-class build
materials result in reference sound quality and stunning dynamics. The SVS Ultra
Series consists of a floorstanding speaker (Ultra
Tower), bookshelf speaker (Ultra
Bookshelf), center speaker (Ultra
Center), and surround speaker (Ultra
Surround) - all sold separately.
Optional Powered Sub: A
SVS powered sub (sold separately) makes a great addition to the Ultra series
