B2 instead of F1 Subwoofer
Your B2 bass modules are passive (no built-in amplifier). The L1 Model II Power Stand provides
- A crossover so the B2 receives frequencies from 40-200 Hz
- EQualization to fine-tune the sound to optimize the features of the B2
- Power: 250 watts RMS
In order to use the B2 without the L1 Model II Power Stand you need to provide the three features above. You can use a Bose PackLite A1 amplifier to provide the power, but you would have to use a third-party device to replace the crossover and EQ.
The F1 Subwoofer has the same three features built-in except that
- The crossover is set lower (closer to 40-100 Hz)
- EQualization emphasizes the frequencies below 100 Hz
- Power: 1000 watts RMS
Two B2s weigh approximately 80 pounds. A single F1 Subwoofer weighs 55 pounds.
