Short answer: the Arendal 1961 Monitor if sound quality matters most, the Polk T15 if price matters most. The Arendal 1961 Monitor ranks #8 of 168 bookshelf speakers, rated 4.3/5, at $1,150. The Polk T15 ranks #153, rated 1.9/5, at $149, $1,001 cheaper.
The Arendal 1961 Monitor is the more accurate pick. A physically robust build the reviewer calls “a little bit of a tank,” delivering low compression, low distortion, and overall really good neutrality: one of the reviewer’s top 10 picks under $1,500 across roughly 250 speakers tested. Its measured preference score, a predictor of how neutral it sounds, is 3.38 against 0.34 for the Polk T15. The tradeoff: Bass rolls off around 70-80Hz, so it cannot be used as full-range mains for music without a subwoofer, and a sub is recommended for home theater use as well.
Why pick the Polk T15: Extremely affordable 2-way design that actually measured better at +/-20 degrees vertical off-axis than directly on-axis. The catch: Spinorama analysis reveals what Amir called a “horrific drop in upper mids/lower treble region of 3 to 6 kHz,” likely from tweeter-woofer phase cancellation directly on-axis.

The Two Speakers In Full
Arendal 1961 Monitor: $1150 per pair Arendal Sound eBay
Same family: the Arendal Sound 1961 Bookshelf (smaller bookshelf, ranked lower, rated 4.2/5), the Arendal 1961 Tower (floorstanding, rated 4.4/5) and the Arendal Sound 1961 Center (center, rated 3.6/5).
Pros: A physically robust build the reviewer calls “a little bit of a tank,” delivering low compression, low distortion, and overall really good neutrality: one of the reviewer’s top 10 picks under $1,500 across roughly 250 speakers tested. Works well both as home theater mains and as surrounds. Independent ASR Klippel measurements corroborate the low-distortion finding: THD at 86dB SPL/1m stays well below the reviewer’s audibility threshold, and even at 96dB SPL/1m it stays “far better than most bookshelves” thanks to the built-in high-pass filter that protects the woofers. Measured bass extension of 84Hz (-3dB), with a measured sensitivity of 85.9dB.
Cons: Bass rolls off around 70-80Hz, so it cannot be used as full-range mains for music without a subwoofer, and a sub is recommended for home theater use as well. Vertical radiation window is narrow, typical of MTM (mid-tweeter-mid) layouts (tighter than a standard two-way’s roughly ±20°) so a second home theater row sitting above or below the tweeter axis will hear a noticeably different tonal balance. ASR’s CEA2034 measurements show the response is elevated above 2kHz with resonant peaks around 3kHz and 9kHz, leading the reviewer to predict it will “likely sound bright.” Those same resonances show up as lingering ridges in the cumulative spectral decay (waterfall) at 96dB SPL/1m.

Polk T15: $149.00 per pair Amazon eBay
Same family: the Polk T50 (floorstanding, rated 3.8/5).
Pros: Extremely affordable 2-way design that actually measured better at +/-20 degrees vertical off-axis than directly on-axis. In near-field desktop use, the reviewer found the T15 “didn’t sound that horrible,” partly because nearby desk reflections mask the frequency response dip. Measured bass extension of 88.6Hz (-3dB), with a measured sensitivity of 89dB.
Cons: Spinorama analysis reveals what Amir called a “horrific drop in upper mids/lower treble region of 3 to 6 kHz,” likely from tweeter-woofer phase cancellation directly on-axis. Measured impedance ranges from 4-8 ohms, contradicting the specified 6-8 ohm range, and there’s a distortion peak around 400Hz. On- and off-axis response “vary a ton,” making listening position unusually important. The reviewer recommends saving up for the Pioneer SP-BS22-LR instead: “I can’t justify recommending the Polk T15 even though subjective performance was not horrible.”
