Throw Over Distance
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?
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.
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.

Model 1S and Model II
Power Stands
Model 1S Model II Cylindrical Radiators
Top Section
Top sections are physically identical (same dimensions).
Note: The actual model designation is on the label on the back channel.
- Top array 39.63” H x 4.15” W x 4.13” D (100.6 cm x 10.6 cm x 10.5 cm)
- Model 1S has silver background
- Model II has black background
Lower Section
Lower sections are physically different (Model 1S is 3.9" shorter).
- Model 1S is approximately 39.63” H x 4.15” W x 4.13” D (100.6 cm x 10.6 cm x 10.5 cm)
- Model II is approximately 43.5” H x 4.15” W x 4.13” D (111.0 mm x 9.0 cm x 10.5 cm)
- Close up view of the ends (Model 1S on top, Model II below)
- Top caps are identical
Questions
Q: Can I use the Model 1S lower extension (no drivers) in the Model II with the Model II Cylindrical Radiator® top section?
- A: No. No sound will come out from the top section.

What Can I Use with What?
Cylindrical Radiator®s
Cylindrical Radiator®s are not interchangeable across models
Specifically (and without exception)
- The Cylindrical Radiator speaker sections of the L1 Classic, the L1 Model I and L1 Model 1S and the L1 Model II are not compatible with each other.
- The Cylindrical Radiator speaker sections of the L1 Classic can only be used with the Classic PS1 power stand (no orange markings on the input/output panel).
- The Cylindrical Radiator speaker sections of the L1 Model I (orange markings on the back of both sections) can only be used with the Model I PS1 power stand (orange markings on the input/output panel).
- The Cylindrical Radiator speaker sections of the L1 Model II can only be used with the L1 Model II power stand.
- The Cylindrical Radiator speaker sections of the L1 Model 1S can only be used with the L1 Model 1S power stand.
