Sub Classification: Transitional Sub
Transitional Subwoofer
Bay Audio classifies three types of subwoofers:
Rumble Subs Designed for bass from 15Hz through 30Hz in theaters. Impact Subs Designed for maximum pressure in the impact zone of 40Hz through 100Hz. Transitional Subs Designed for bass reinforcement from 50Hz and above, specifically for smaller rooms, or used in a transitional capacity with Impact subs.

What’s Loud Enough?
We like subwoofers to produce at least 96dB continuous (100dB for high-impact theaters) throughout their range at the listening position.
For background music systems, performance to 85dB is appropriate.
Determining Room Volume
Room volume is Width x Length x Height of the primary listening room, plus a portion of the volume of any rooms that are connected. When placing a subwoofer in position 1, add 25% of the volume of Room B. In position 2, add 50%. In position 3 add 100% of room B.

Determining Output
Corner Loaded SPL
Placing the SPK-OSUB low in a corner will yield the greatest bass output. Adding a second Sub adds 3 to 6dB of output, depending upon how close the subwoofers are to each other. The chart assumes the first subwoofer is placed in the corner, and the second is alongside a side wall.
Volume First Sub Second Sub
1,500 ft3 98dB 103dB 3,000 ft3 96dB 101dB 5,000 ft3 94dB 99dB 7,000 ft3 92dB 97dB
Wall Loaded SPL
Use these SPL charts when placing the SPK-OSUB at least 4 feet from the floor or an adjoining wall. This chart assumes both subwoofers are placed at least 4’ from the floor and adjoining walls.
Volume First Sub Second Sub
1,500 ft3 93dB 98dB 3,000 ft3 91dB 96dB 5,000 ft3 89dB 94dB 7,000 ft3 87dB 92dB
