Rockville SPG88 vs Biamp Community V2-28

Last updated: October 11, 2026

Short answer: the Rockville SPG88, though neither ranks well in its class. It ranks #41 of 44 8-inch pa speakers by sound quality, rated 2.5/5, at $64.95; the Biamp Community V2-28 ranks #42, rated 2.4/5, and costs $851, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 44 8-inch pa speakers, and the QSC K8.2, ranked #1 at $749.99, is a better place to start if sound quality matters.

Rockville SPG88 vs Biamp Community V2-28

The Rockville SPG88 is the more accurate choice. A budget passive PA speaker with an 8” woofer in an ABS cabinet. Its measured preference score, a predictor of how neutral it sounds, is -0.89 against -1.60 for the Biamp Community V2-28. The tradeoff: Bass is limited and the on-axis response is uneven (1.75 average deviation), and that data is low quality.

The Biamp Community V2-28 is the deeper-bass choice. Two 8-inch woofers and 94dB sensitivity give more output than the single-woofer Biamp Community V2-8, with bass to about 59Hz at -10dB in vendor measurements. Its bass reaches about 90Hz before falling 3dB, against 111.5Hz for the Rockville SPG88. The tradeoff: Preference scores of -1.6 standalone and 1.65 with an ideal subwoofer are among the lowest here, because the listening window spreads across a 9.9dB band.

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. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.
