Monoprice SW-12 vs SVS SB-3000

What the Monoprice SW-12 gets right: 12-inch ported with 400W RMS (600W peak) on a budget at just $230. Hits hard with clean tight transient response. The tradeoff: Entry-level build quality, ported enclosure room interaction, and lower 112.3 dB output capability.

On the SVS SB-3000 side: 13-inch sealed with 800W RMS (2500W peak) delivers 118.7dB average with exceptional accuracy. The tradeoff: Ported cabinet room-mode dependency, compact 25 kg (55.1 lbs) size limits bass extension, and $1,100 investment.

SVS SB-3000: $1,099.00 Amazon eBay

SVS SB-3000 ranking card

Pros: 13-inch sealed design with 800W RMS (2500W peak) that Audioholics measured at a 118.7dB CEA-2010-A average from 40-80Hz, and rated by SVS at 18-270Hz within ±3dB. Beautifully made with pinpoint control and flawless tonal accuracy. Sweet spot performance-to-value ratio. Three-band parametric EQ with 1Hz precision adjustment.

Cons: Being sealed, it gives up deep-bass output: Audioholics measured 96.6dB at 20Hz and 101.7dB at 25Hz, about 15dB behind the ported SVS PB-3000 from the same series, so a large room or reference-level movie bass may call for a second sub.
