Polk Audio Reserve R700 vs Magnepan LRS+

Last updated: August 15, 2026

Short answer: the Polk Audio Reserve R700. It ranks #22 of 54 floorstanding speakers by sound quality at $1199; the Magnepan LRS+ ranks #48 and costs $1300, so there is not much of a tradeoff to weigh.

What the Polk Audio Reserve R700 offers: 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 Magnepan LRS+ offers: Thin, two-way planar-magnetic open-baffle/dipole panel design (about 48” tall, just 1” deep). Watch for: Extremely current-hungry and power-hungry: even a pair of 600W Macintosh monoblock amplifiers only averaged about 90dB output - a robust, high-power amplifier is essentially mandatory, and budget amps won’t cut it.

Buy the Polk Audio Reserve R700. It ranks higher for sound quality than the Magnepan LRS+ and costs less, so there is no real case for the other one.

If sound quality matters at all to you, skip the Magnepan LRS+. It ranks near the bottom of the 54 floorstanding speakers, so look higher up the list instead.

Polk Audio Reserve R700 ranking card

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.

Magnepan LRS+: $1300 Magnepan

Magnepan LRS+ ranking card

Pros: Thin, two-way planar-magnetic open-baffle/dipole panel design (about 48” tall, just 1” deep). Delivers a uniquely dramatic and enveloping soundstage with genuinely three-dimensional depth effects that work across all music genres, not just classical or orchestral material as commonly assumed. Extremely tight, locked-in center-phantom imaging when set up correctly. Open-baffle design avoids the “boxy” enclosure coloration of conventional cabinet speakers. Multitone distortion is remarkably consistent from low to high frequency, a characteristic the reviewer hasn’t observed in conventional cone-and-dome speakers. Compression at high output stays modest (about 0.5-1dB) through the midrange and treble, giving roughly 20-26dB of usable dynamic range in that region. At its price, a strong contender for a dedicated secondary listening room, even if not a main-system replacement.

Cons: Extremely current-hungry and power-hungry: even a pair of 600W Macintosh monoblock amplifiers only averaged about 90dB output - a robust, high-power amplifier is essentially mandatory, and budget amps won’t cut it. Bass rolls off very quickly (F3 74Hz, F10 67Hz, described as falling off “like a rock”), making a subwoofer an absolute requirement for any low-end content. A roughly 3dB dip in the mid-bass (100-300Hz) region thins out vocal body and fullness compared to a conventional bookshelf speaker. A resonance/bump around 400Hz adds a mild boxy quality, though it responds well to about 2dB of EQ correction. Extraordinarily fussy about exact positioning - both seating height (must align with the acoustic reference point between the panel’s lower tie-down points) and horizontal aiming are unusually critical; moving just a couple of inches can cause treble content above roughly 500-600Hz to nearly vanish. Distinct off-axis cancellation zones exist directly to the sides of the panel, where very little sound is audible at all. Fails badly under extreme dynamic-transient testing in the bass, and the reviewer blew fuses pushing the speaker during testing - not built for high-volume or highly dynamic playback. A genuinely different category from conventional hi-fi speakers, requiring more setup patience and experimentation than a typical monopole design.
