Polk Audio Reserve R100

Sources split three ways, but most of the weight hears a neutral speaker. i-fidelity's lab, its listening reviewer, StereoNET, Steve Guttenberg, cheapaudioman and ASR's napilopez all describe it as flat, natural or 'right down the middle'. Guttenberg found it more neutral than a B&W 607 S2. A second group hears it lean bright: Erin found the treble too much as he turned it up at 4 m, an ASR owner hears more treble than a Wharfedale Diamond, and likehifi missed some warmth. A third group hears it warm: ON-mag describes warm, punchy bass and sparkling highs, and Nemo Audio Project heard a warm midrange with his ears at woofer height. Nemo could make it sound brighter by aiming the tweeter at his ears, so volume, toe-in and stand height explain much of the split.

Sources split. The larger share of the weight finds the bass light for full-range listening: Erin says there's no real 'heft', Nemo Audio Project calls a subwoofer mandatory, DCinside's Nuyes agrees, likehifi missed body in the lower registers, and owners who also own the R200 call the gap in depth dramatic. The other camp finds it punchy and surprisingly full for a 5.25-inch woofer. i-fidelity was astonished by its power in a small box, cheapaudioman calls it the best all-round bass he'd heard in a speaker at the price, and ON-mag praises warm, punchy, well-controlled bass. StereoNET sits between them: deep and extended, but not the most powerful. Nearly every source suggests a subwoofer for big rooms.

The R100's clearest strength, praised by nearly every source. StereoNET calls the midband vivid and engaging. Diapason found it particularly expressive, and ON-mag calls it very open and airy. Erin was struck by midrange punch that reminded him of a good small studio monitor, and owners call its clarity and smoothness incredible. Erin's near-field data does show a resonance between 500 Hz and 1 kHz, but no source says they could hear it.

“The R100’s midband is vivid and engaging.”

Michael Darroch, StereoNET (Denon Home Amp)

“Le médium est particulièrement expressif et éloquent, les R100 sont des musiciennes généreuses et accomplies, à budget serré.”

Diapason d'Or 2021 (French: 'The midrange is especially expressive and eloquent; on a tight budget the R100s are generous, accomplished musicians')

“The midrange clarity and smoothness is incredible.”

Zaph_42, r/BudgetAudiophile (owns the R100, R200 and R700)

Mostly praised. StereoNET found it controlled, extended and accurate, likehifi ultra-detailed without being sharp, cheapaudioman and Nemo Audio Project heard no fatigue over long sessions, and an Indian listener at a dealer said it never sounded bright. The dissent comes from the same direction as the tonality split: Erin found it too much at high volume, an ASR owner hears more treble than a Wharfedale Diamond but not objectionably, and two ASR members flag the tweeter as the speaker's weak point.

“At the same time, treble sounds controlled, extended, and accurate – and duly delivers a most satisfying listening experience.”

Michael Darroch, StereoNET

“there's still great clarity but there's no fatigue and that's exactly uh what it's like with the r100”

cheapaudioman (YouTube)

“Check the Estimated In-Room Response graphic and you’ll see a +3dB rise in the high frequency relative to the trendline set by the midrange.”

Erin's Audio Corner

A consistent strength. StereoNET found the soundstage expansive even when the speakers were badly placed. i-fidelity praised the airy space around voices and instruments, and cheapaudioman heard sounds go outside the speakers in all three of his rooms. Nemo Audio Project and Diapason agree. ON-mag found it very wide with pleasant depth, if not exceptional in relief.

“The R100 provides an expansive soundstage, too, even with less-than-ideal positioning.”

Michael Darroch, StereoNET

“Da ist zum einen der Raum um Stimme und Instrumente, der ein wunderbares Maß an Luftigkeit bietet.”

Olaf Sturm, i-fidelity.net (German: 'There is the space around voice and instruments, which offers a wonderful degree of airiness')

“i will say that the soundstage and imaging in every situation was great”

cheapaudioman (YouTube; office, bedroom and living room)

Precise and stable. i-fidelity heard a singer projected 'impeccably' into the centre, likehifi found every element firmly placed, and cheapaudioman and Nemo Audio Project rank it among the best-imaging speakers at the price. ON-mag found the focus good.

“Alle Instrumente sind um diese fantastische Stimme arrangiert, welche die R100 tadellos ins Zentrum projiziert.”

Olaf Sturm, i-fidelity.net (German: 'All the instruments are arranged around this fantastic voice, which the R100 projects impeccably into the centre')

“L'image stéréophonique est très large, pas d'un relief exceptionnel, mais d'une agréable profondeur avec une focalisation réussie et une bonne différenciation des strates sonores.”

Pierre Stemmelin, ON-mag (French: 'The stereo image is very wide, not exceptional in relief, but with pleasant depth, good focus and good separation of layers')

Mostly praised as revealing. Diapason calls its level of information astonishing for the price and size, and i-fidelity and likehifi both single out its resolution. StereoNET warns that it exposes poor recordings and lossy streams. ON-mag dissents: it hears a speaker that favours charm over precision.

“Le niveau d’information et de sensibilité est renversant en regard du prix et du volume de cette petite 2 voies.”

Diapason d'Or 2021 (French: 'The level of information and sensitivity is astonishing for the price and size of this small two-way')

“This said, the little Polk is unforgiving if your source material is poor.”

Michael Darroch, StereoNET

“Elles ne cherchent pas à faire dans l'hyper transparence, préférant miser sur la séduction plutôt que sur la précision implacable.”

Pierre Stemmelin, ON-mag (French: 'They don't aim for hyper-transparency, betting on charm rather than relentless precision')

Sources split almost evenly, and the split tracks volume and room size. Erin measured heavy bass compression at high levels and heard the treble harden. Steve Guttenberg felt it strain above about 85 dB, and an ASR member who owned it says it 'crumbles' when pushed, unlike the R200. On the other side, i-fidelity was astonished by the power it found in electronic music, likehifi thought it sounded best a little louder, and cheapaudioman got all the volume he needed in his rooms. Both camps advise a subwoofer or the R200 for parties and large spaces.

Fairly forgiving, with setup-specific advice rather than a real split. i-fidelity suggests stands with the tweeters at ear level, and says the R100 can move a little closer to the back wall for bass support, as StereoNET also suggests. Nemo Audio Project found that wall distance changed the bass less than with other speakers. He preferred a slight toe-in with his ears at woofer height; with the tweeter aimed at his ears it sounded livelier. Two owners found it cleaner with some space from the wall: one says it sounds a little too warm when close to a back wall.

“Erfreulicherweise versucht die R100 keinen Bass vorzutäuschen, daher darf man sie zur Bassunterstützung bei Bedarf etwas näher vor die Rückwand stellen.”

i-fidelity.net lab report (German: 'Happily the R100 doesn't try to fake bass, so it can go a little closer to the back wall for bass support if needed')

“i found these speakers sounded best with just a little bit of toeing and my ear at the height of the mid bass driver”

Nemo Audio Project (YouTube)

“Both also seem to sound a little too warm or less clean when too close to a back wall.”

Zaph_42, r/BudgetAudiophile (R100 and R200 owner)

Moderate, and it depends on the setup. Its impedance dips to about 3.5 ohms and sensitivity is about 86 dB, so StereoNET, Steve Guttenberg and ON-mag all advise an amplifier that is happy with 4-ohm loads or has some muscle. Diapason reports that Polk recommends at least 70 W per channel. In smaller rooms it is less fussy: cheapaudioman drove it from a 6-watt tube amp and got all the volume he needed.

“However, with a minimum impedance of 3.6 ohms and a sensitivity of 86dB, you will want to make sure you have an amplifier with decent load-driving ability.”

Michael Darroch, StereoNET

“i was running this off of a tube amp a six watt tube amp and it was a fantastic pairing and i got it as loud as i needed it with off of just six watts”

cheapaudioman (YouTube)

“Il ne faut pas hésiter à les associer à un ampli un peu musclé pour les bousculer.”

Pierre Stemmelin, ON-mag (French: 'Don't hesitate to pair them with a slightly muscular amp to wake them up')

Well liked for fit and finish: StereoNET praises seamless rounded edges, solid nickel-plated binding posts and magnetic grilles, and cheapaudioman thinks it is better built than its Elac rivals. The black finish is a vinyl wrap, which ON-mag and Steve Guttenberg found well executed. Reliability reports are few but real. The ASR member who lent Erin the review unit says the pair's other tweeter developed a crackle after two months, and a 2026 buyer received a damaged cabinet.

“The rounded edges of the cabinet are bonded together seamlessly to create a fit that screams quality, and the rear nickel-plated binding posts look solid enough to support the weight of a person (disclaimer – don’t do this).”

Michael Darroch, StereoNET

“The tweeter was not DOA, but developed a crackling sound after about 2 months.”

beaRA, Audio Science Review forum (owner who lent Erin the review unit)

“This is my first pair of bookshelves, and for $800 I feel like their quality control shouldn't let this slide.”

TBoucher8, r/audiophile (pair arrived with a damaged cabinet)

Good value to most. i-fidelity says the only thing wrong with it is the price, Diapason calls so much engineering at the price unexpected, and cheapaudioman ranks it alongside anything Elac makes at the price. Two reservations recur. Erin thinks the money went into the looks rather than a better crossover, and several owners and Steve Guttenberg say the R200 is the better buy for about $100 more if it fits your space. Polk's own store and Amazon regularly sell it below the $699 list price (about $559 in October 2026).

“this speaker goes toe-to-toe with anything that elac is making in the in this price range not only does it go to toe to toe with anything that elac is making it's prettier and it's built better at the same price”

cheapaudioman (YouTube)

“I just feel like this speaker could have been an even better buy with a little bit more put into the crossover.”

Erin's Audio Corner

“Listening without a sub, the difference in bass depth between the R200 and R100 is dramatic and makes me prefer the R200.”
