Quick questions
Which subwoofer is better for movies, PB-1000 Pro or SB-1000 Pro?
The PB-1000 Pro is generally better for movies due to its ported design, which produces deeper bass extension (down to 17 Hz) and higher output. It delivers the rumbling, tactile effects that make action scenes and explosions feel immersive. The SB-1000 Pro can still perform well in smaller rooms, but it lacks the same low-end authority.
Can the SB-1000 Pro work in a large room?
It can, but it may struggle to pressurize a large space compared to the PB-1000 Pro. The sealed design has lower maximum output and less deep extension. For rooms over 2,000 cubic feet, the PB-1000 Pro is usually recommended. However, using two SB-1000 Pros can help overcome size limitations.
Is the PB-1000 Pro too boomy for music?
Not necessarily. The PB-1000 Pro has a well-tuned port that avoids excessive boominess, and its DSP allows fine-tuning. However, some purists prefer the sealed SB-1000 Pro for music because its transient response is faster and tighter, making it sound more articulate. For most listeners, the PB-1000 Pro still performs admirably with music, especially in larger rooms.
