Short answer: the Palmer Orbit 11 if sound quality matters most, the ADAM Audio T8V if price matters most. The Palmer Orbit 11 ranks #61 of 119 powered bookshelf speakers, rated 4.2/5, at $1,532. The ADAM Audio T8V ranks #94, rated 3.9/5, at $719.98, $812.02 cheaper.
What the ADAM Audio T8V does well: Measured -3dB extension of 39.6Hz gives useful bass depth for an affordable large monitor. The tradeoff: The 6.31 ideal-subwoofer score and 3.0dB response span from 300Hz to 5kHz show less even tonal balance than stronger budget alternatives.
The Palmer Orbit 11 is the more accurate, deeper-bass option. A 27.8Hz measured -3dB point provides genuinely deep standalone bass. Its measured preference score, a predictor of how neutral it sounds, is 6.20 against 4.65 for the ADAM Audio T8V. Its bass reaches about 27.8Hz before falling 3dB, against 39.6Hz for the ADAM Audio T8V. The tradeoff: Its 7.10 ideal-subwoofer score is more modest than the narrow midrange span alone suggests; response outside that band and off-axis behavior also matter.
Buy the ADAM Audio T8V if the price matters more than sound quality. Buy the Palmer Orbit 11 if sound quality matters more than the price.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.
