Short answer: the Polk Audio Reserve R700 for better sound quality, the Emotiva Airmotiv T2+ for the lower price. The Polk Audio Reserve R700 ranks #33 of 73 floorstanding speakers, rated 4.3/5, at $2,398. The Emotiva Airmotiv T2+ ranks #35, rated 4.2/5, at $999, $1,399 cheaper.
The case for the Polk Audio Reserve R700: 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. Watch for: 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.
What the Emotiva Airmotiv T2+ does well: High-value three-way tower with strong output and unusually deep usable sealed-room bass for the price. The tradeoff: The nominal 4-ohm system approaches 3 ohms near 100Hz in Erin’s measurement, so a high-current amplifier is preferable.
Worth knowing: the Emotiva Airmotiv T2+ is discontinued, though it still ranks #35 of 73 floorstanding speakers by sound quality, so a used unit beats most of what is still sold new.
Buy the Polk Audio Reserve R700 when sound quality outweighs the price for you, and the Emotiva Airmotiv T2+ when the price outweighs sound quality instead.

Polk Audio Reserve R700: $2,398 per pair 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 $1199/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. 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.

Emotiva Airmotiv T2+: $999 per pair Discontinued Emotiva eBay
Newer model: the Emotiva Airmotiv XT2. It’s likely to perform similarly, though we don’t have measurements to confirm that yet.
Pros: High-value three-way tower with strong output and unusually deep usable sealed-room bass for the price. Erin measured F3 at 62Hz and F10 at 32Hz, with sensitivity just under 90dB/2.83V/1m. Dual 8-inch woven-fiber woofers relieve the 5.25-inch midrange, and the 32mm folded-ribbon tweeter provides broad horizontal coverage. Approximately +/-2.5dB response linearity, solid cabinet bracing and low compression allow substantial playback levels; the gradual low-frequency roll-off integrates well with either room gain or a subwoofer. Measured bass extension of 62Hz (-3dB), with a measured sensitivity of 89.5dB.
Cons: The nominal 4-ohm system approaches 3 ohms near 100Hz in Erin’s measurement, so a high-current amplifier is preferable. Horizontal and especially vertical directivity through the midrange/tweeter transition is less uniform than the best waveguided or coaxial designs; listener height and nearby reflections matter, and EQ cannot correct the narrowing mismatch. The large rear-ported cabinet needs placement clearance, and its deep F10 should not be confused with flat 30Hz output at cinema levels. Discontinued.
