How do I know which subwoofer is right for me?

The Sub1 and Sub2 powered bass modules are both designed to give you optimal bass performance no matter what your application is. However, singer-songwriters with acoustic guitars find the Sub1 to be the best fit for them, and it is smaller and more portable. DJs or keyboard players may benefit more from the additional bass performance of the Sub2, which is larger, but plays lower and louder. If you are playing content with very low frequencies, such as electronic dance music, you will probably want a Sub2. 

How do I connect my Subwoofers?

The Sub1 and Sub2 powered bass modules have identical user interfaces and function in the same way. You can connect them with a SubMatch cable directly to your L1 Pro system or use a balanced 1/4" audio cable. They are both powered subwoofers, and the benefit of the SubMatch cable is that it delivers both audio and power, so you don’t have to plug the Sub1 or Sub2 into a wall outlet. A SubMatch cable is included in the box with the L1 Pro32 for connecting to your Sub1 or Sub2. If you are using a balanced 1/4" audio cable, you will need to plug the Sub1 or Sub2 into wall power.

How many subwoofers can I connect to my system?

We recommend a maximum of two subwoofers per L1 Pro system. This is to ensure optimal tonal balance.
