Product Description
The SVS SB17-Ultra R|Evolution is the sealed-cabinet flagship of SVS's 17-Ultra R|Evolution series, built around a completely new 17-inch driver featuring the industry's first dual 8-inch voice coil design. Paired with a 55lb four-piece toroidal ferrite motor and a lightweight, rigid glass-fiber composite cone, the driver is capable of extreme excursion with exceptional linearity and control. Power comes from the Sledge STA-2800D amplifier, delivering 2800 watts RMS continuous power and over 6000 watts of peak dynamic output, governed by a 295MHz Analog Devices audio DSP with double-precision 56bit filtering for reference-level accuracy. The sealed cabinet design trades some ultimate output for tighter, more precise, more musical bass in a comparatively compact footprint, making the SB17-Ultra R|Evolution equally at home driving reference-level home theaters and demanding two-channel music systems. Full control is available through XLR and RCA stereo connections and the SVS smartphone app, with parametric EQ, adjustable phase, polarity, and multiple tuning modes.

Frequently Asked Questions (FAQs)
How is the SB17-Ultra different from the PB17-Ultra?
The SB17-Ultra uses a sealed cabinet for tighter, more precise, "musical" bass in a smaller footprint, while the PB17-Ultra uses a ported cabinet for greater maximum output and deeper low-frequency extension at the cost of a larger enclosure.
What amplifier power does the SB17-Ultra R|Evolution use?
It uses the Sledge STA-2800D amplifier, delivering 2800 watts RMS continuous power and over 6000 watts of peak dynamic power.
Does it support both music and home theater use equally well?
Yes. The sealed design and extremely accurate driver and DSP combination make it well suited to fast, articulate bass for music as well as the extension and impact needed for movies and gaming.

- After Sales Support - The only issue with Hi-Fi equipment is that you will not find local service centers in every city. Most of the brands have their service centers only in the metro cities and hence it becomes difficult for the customers who are living far away places to claim warranty. At AV Kart, we solve this problem by arranging pikcup and drop facility from the nearest service center with the help of our logistic partners.
