Short answer: the Bowers & Wilkins DB4S. Both are rated 3.8/5 for sound quality (#49 and #64 of 212 subwoofers), and the Bowers & Wilkins DB4S costs $2,499 against $3,456.29 for the Sigberg Audio INKOGNITO 12, so with nothing between them on sound quality, price settles it.
What the Bowers & Wilkins DB4S does well: Single forward-firing 10-inch Aerofoil drive unit powered by 1,000 watts of Class D Hypex amplification in a rigid sealed enclosure. The tradeoff: A single 10-inch sealed driver produces less deep bass headroom below 30Hz than larger ported models or dual-opposed designs like the Bowers & Wilkins DB2D and Bowers & Wilkins DB1D.
Why pick the Sigberg Audio INKOGNITO 12: Ultra-slim 12-inch sealed design (6.69” depth) with 250W RMS reaches 23Hz.
Buy the Bowers & Wilkins DB4S. Both are rated the same for sound quality, and it costs $957.29 less than the Sigberg Audio INKOGNITO 12.
