Short answer: the Polk Reserve R700 is the value-focused tower with excellent bass and smoothness, while the SVS Ultra Evolution Pinnacle is the larger flagship built for more extension and scale. The Polk reaches 40Hz at -3dB and remains close to ±2dB on-axis; the SVS reaches an exceptional 27Hz with four force-balanced 8-inch woofers.
SVS also offers broader roughly ±75-degree horizontal coverage and higher sensitivity, but its complex driver transitions do not produce class-leading response smoothness, and each cabinet weighs nearly 97 lbs (44 kg). The Polk needs a capable amplifier because it is effectively a 4-ohm load, and its treble can compress at extreme output.
Buy the Polk Audio Reserve R700 for remarkably deep, smooth three-way performance without flagship cost or flagship weight.
Buy the SVS Ultra Evolution Pinnacle for maximum full-range extension, broad coverage, and large-room output.

The Two Speakers In Full
Polk Audio Reserve R700: $2,398 per pair Amazon eBay
Same family: the Polk Reserve R100 (smaller bookshelf, rated 3.4/5), the Polk R200 (larger bookshelf, rated 3.2/5), the Polk Reserve R500 (smaller floorstanding, ranked lower, rated 4.2/5), the Polk Reserve R600 (smaller floorstanding, ranked lower, estimated 4.2/5), the Polk Audio Reserve R300 (smallest center, estimated 3.6/5), the Polk Audio Reserve R350 (center, rated 3.7/5) and the Polk Audio Reserve R400 (largest center, estimated 3.8/5).
Pros: Three-way design with a 1” ring radiator tweeter, 6.5” mid-range, and dual 8” mid-bass drivers in a ported, down-firing cabinet. On-axis frequency response holds within about ±2dB across most of its range, with genuinely deep bass extension (F3 40Hz) reaching into the mid-30s Hz in-room. Wide horizontal radiation of about ±70°, giving a strong, enveloping stereo width and stage-extension effect on well-recorded tracks. Good low-level dynamics: solid bass thump at quiet listening volumes without over-accentuation. Strong distortion and compression control through the bass and midrange. Real nominal impedance closer to 4 ohms than the marketed 8 ohms, so with the right amplifier it can be driven hard: a $3,000 two-channel integrated brought out significantly more life than a budget $300 unit could. Excellent value at its roughly $1199/pair, ranking among the reviewer’s top picks under $2,500; outperforms the similarly-priced Klipsch RP-8000F II in bass extension and overall smoothness. Measured bass extension of 40Hz (-3dB), with a measured sensitivity of 87.5dB.
Cons: Compression in the high frequencies rises sharply between 96dB and 102dB output: a real limitation only at very high volumes (around 100dB at 3 meters), but a clear step down from pricier ($5,000+) towers. Horizontal directivity mismatch around 4-5kHz, where the tweeter flares wider than the midrange, can sound a bit forward, especially noticeable when toed out further into the room; sidewall absorption or curtains help tame it. Harmonic distortion crosses the reviewer’s 3% threshold around 7kHz at 96dB output, possibly contributing to that same forward quality at high volume. Narrow vertical sweet spot (about ±15° from the tweeter axis), typical of non-coaxial tower designs: more of a consideration for multi-row home theater seating than single-row listening. The ring-radiator tweeter narrows noticeably above about 7-8kHz, and toeing the speaker out more than about 20° causes the top end to fall off quickly. Needs at least 2 feet of clearance from the rear wall to avoid boomy, exaggerated bass, since it lacks the bass-shelf tuning some rivals use to allow closer wall placement. Compared to the pricier KEF R5 Meta, has narrower horizontal (and much narrower vertical) directivity, so seating flexibility is more limited.

SVS Ultra Evolution Pinnacle: $2,499.00 per pair Amazon SVS eBay
Same family: the SVS Ultra Evolution Nano (smaller bookshelf, estimated 3.9/5), the SVS Ultra Evolution Bookshelf (larger bookshelf, estimated 4/5), the SVS Ultra Evolution Tower (smaller floorstanding, ranked higher, estimated 4.1/5), the SVS Ultra Evolution Titan (smaller floorstanding, ranked higher, estimated 4.2/5) and the SVS Ultra Evolution Center (center, estimated 4.1/5).
Pros: Flagship three-way tower with a diamond-coated tweeter, dual midranges and four force-balanced 8-inch woofers. Erin measured exceptional 27Hz extension, broad roughly +/-75-degree horizontal coverage, an 88.1dB sensitivity and a 4.91 preference score even without a subwoofer. Measured bass extension of 41.0Hz (-3dB).
Cons: The 5.25-to-8-inch transitions and complex array do not produce class-leading smoothness: 0.184 on-axis, 0.226 predicted in-room and 3.64 directivity-index consistency. At 96.7 pounds each, these are difficult to position, and their Q of 1.25 indicates some bass emphasis. A dip in the upper midrange followed closely by a peak around 2 to 3kHz gives vocals a shouty, forward quality that toe-out alone does not resolve.
