Summary

These are projections and estimates based on previously published data from Bose.
Assumptions:

  • All values are calculated at 2 kHz
  • S1 Pro, L1 Compact, L1 Pro8, F1 Model 812 have a critical distance[1] of 0 meters/feet[2]
  • L1 Model 1S and L1 Pro16 have a critical distance[1] of approximately 3 meters (10 feet)[2]
  • L1 Model II and L1 Pro32 have a critical distance[1] of approximately 10 meters (33 feet)[2]

L1 Pro Throw Over Distance

This is the chart used to estimate critical distance and drop-off over distance. The source is 13:25 Which L1 Pro Portable System is Right for You?

Throw Over Distance

L1 Pro Compared to L1 Legacy

Assuming that all systems are run at their rated maximum outputs:

  • L1 Pro8 will be +6 dB SPL higher than the L1 Compact at any distance
  • L1 Model 1S will be +3 dB SPL higher than the L1 Pro8 at any distance
  • L1 Pro16 will be +6 dB SPL higher than the L1 Model 1S (beyond 2 meters)
  • L1 Model II will be +3 dB SPL higher than the L1 Pro16 (beyond 4 meters)
  • L1 Pro32 will be +7 to +10 dB SPL higher than the L1 Pro16 (beyond 4 meters)
  • L1 Pro32 will be +7 dB SPL higher than the L1 Model II at any distance

The table below is adapted from the chart from Bose[2] and previously published data.

Throw Over Distance L1 Pro vs. L1 Legacy


All Models

Assuming that all systems are run at their rated maximum outputs:

  • L1 Compact will be +6 dB SPL higher than the S1 Pro at any distance
  • L1 Pro8 will be +6 dB SPL higher than the L1 Compact at any distance
  • L1 Model 1S will be +3 dB SPL higher than the L1 Pro8 at any distance
  • L1 Pro16 will be +6 dB SPL higher than the L1 Model 1S (beyond 2 meters)
  • L1 Model II will be +3 dB SPL higher than the L1 Pro16 (beyond 4 meters)
  • L1 Pro32 will be +7 dB SPL higher than the L1 Model II at any distance
  • F1 812 is +4 dB SPL higher than the L1 Pro32 but the drop-off over distance is greater. The result: Beyond 6 meters (20 feet) the L1 Pro32 has higher SPL.

The table below is adapted from the chart from Bose[2] and previously published data.
