#26 Polk Audio Reserve R700: $1,199.00 Amazon eBay

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 $2,200/pair MSRP, ranking among the reviewer’s top picks under $2,500; outperforms the similarly-priced Klipsch RP-8000F II in bass extension and overall smoothness.

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.

How it compares: Just above it: Morel Avyra 633 - $801 more, 1Hz lower bass extension (-3dB). Just below it: Q Acoustics 5040 - $37 more, 4Hz higher bass extension (-3dB).
