Short answer: the Monoprice Monolith M-10 V2 for deep bass in a smaller box, the SW-15 for a large room. The M-10 V2 is a 10-inch THX-certified ported sub reaching 17-20Hz on 500W RMS, and it costs $378.98 more. The SW-15 is a 15-inch ported design with 600W RMS (800W peak) and a Large-room Bassaholic rating, though it is budget-tier with ported room gain dependency, a 30 kg (66.1 lbs) frame and limited dynamic headroom.
On the Monoprice Monolith M-10 V2 side: 10-inch THX-certified ported with 500W RMS reaches 17-20Hz.
The case for the Monoprice SW-15: 15-inch ported with 600W RMS (800W peak) delivers Large-room Bassaholic rating. Set against that: Budget-tier design, ported room gain dependency, 30 kg (66.1 lbs) mid-size, and limited dynamic headroom.
