Short answer: the Ascend Acoustics Luna V2 Mini-Monitor Titan on measured sound quality, the Polk T15 on price. The Ascend Acoustics Luna V2 Mini-Monitor Titan ranks #10 of 87 bookshelf speakers at $898. The Polk T15 ranks #78 at $149, $749 cheaper.
What the Polk T15 offers: 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. Watch for: 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.”
What the Ascend Acoustics Luna V2 Mini-Monitor Titan offers: A Klippel NFS optimized crossover and proprietary 4.5 inch long throw glass fiber woofer give this compact mini-monitor a large soundstage for its size, at Ascend’s most accessible price point. Backed by the same 7 year parts and labor warranty and hand matched pairs as Ascend’s larger models, with each unit shipped with its own production line frequency response printout. Watch for: On axis deviation measures 0.599dB average, the roughest figure of any speaker added to this catalog from spinorama.org’s current measurement set, so a listener sitting dead center is more likely to notice unevenness than with the RAAL ribbon version of this same cabinet. Bass extension is limited by the small 4.5 inch woofer to a measured 74.7Hz at -3dB, so it needs a subwoofer for full range listening. Ascend sells direct only, with no dealer network for an in person audition.
Buy the Polk T15 if the price is the priority over sound quality, or the Ascend Acoustics Luna V2 Mini-Monitor Titan if sound quality is the priority over the price.
The Polk T15 is not a sound-quality pick. It sits near the bottom of the 87 bookshelf speakers; there are better options higher up.
