Use the SIRA SLA-1 to upgrade a system with even more punch. Even though this model has all of the power of big subwoofers, it is small in size. It can either stand pretty or lie down and be hidden away under a couch, shelf, etc. Like every other speaker model, it’s totally wireless. That way, you can feel and hear the added bass drums, but not even see them.
Adding one (or even more) subwoofers to a system lets you play deeper, louder, and tighter. The system automatically recognises it, and will adjust all speakers to match perfectly. That lets those play your tones cleaner, and lets this unit take care of the heavy lifting.
