RSL Speedwoofer 10S MKII
A 350 W 10-inch that hits cleanly into the low 20s — the most sub for the money before diminishing returns set in.

Subwoofers & Low Frequency
For 10–200 Hz sweeps and room-mode hunting.
Most "my sub sounds wrong" problems are placement problems. These picks can play cleanly low enough to expose them, with the controls needed to integrate with real speakers in real rooms.
From a compact sealed 12-inch to a budget option that still reaches the low 30s, every pick has honest low-frequency limits.
What to look for
- Useful output well below 40 Hz, not just on paper.
- Low distortion and no port chuffing at the levels you use.
- Adjustable crossover and phase so it integrates with your mains.
- Sealed or well-tuned ported alignment for predictable room behavior.
- Auto-on and standby that do not clip the first note.
- Size and placement options that fit the room.
