A Portable Powerhouse Subwoofer!

Add some serious bottom end to your portable PA system with the Bose Sub1 bass module from Sweetwater. With a slim profile and a 480W Class D amplifier design, the Sub1 churns out serious low-end performance — all the way down to a bone-rattling 40Hz! How does the Sub1 deliver the low-end goods while remaining compact? The answer is its 7-inch by 13-inch Racetrack driver. Often found in small audio systems, Racetrack drivers use an elongated cone shape to match the performance of traditional circular speaker cones in a slimmer format. Bose has enlarged the typical Racetrack driver design to deliver solid, room-filling low end from a slim, travel-friendly footprint. The Bose Sub1 can complement nearly any portable PA, but thanks to optimized EQ setting, it pairs perfectly with the Bose S1 Pro system. And, if you want to elevate it, the Sub1 includes an M20 threaded insert for mounting to Bose’s adjustable speaker pole accessory.

Bose Sub1 Bass Module for L1 Pro Portable PA Systems Features:

  • Compact subwoofer for portable PA systems
  • 480W Class D amplifier delivers low-end down to 40Hz
  • Slim 7-inch x 13-inch Racetrack driver matches the performance of larger traditional speakers
  • Optimized EQ setting for S1 Pro makes dialing in your PA a piece of cake
  • Connects to Bose L1 Pro32 system with SubMatch cable (sold separately)
  • M20 threaded insert for mounting to an optional Bose adjustable speaker pole

It Rocks.
I am a solo acoustic music performer.
I purchased the Sub 1 to add to 2 S1 Pro's.
Although the S1 Pros provided excellent sound, the Sub 1 makes for a complete PA system. Highly recommend the Sub 1.
This sud is the most and the best sound out there I've a portable size!
I got the sub when it came out to go with 2 s1pros and Wow!it really brought them to life. I did some out door events that people came up to me and said ( Is that all that sound coming out of those little speakers? ) before I could say anything someone said ( well it is Bose. After that I had seen reviews of the sub 2 with 2 s1pros so I thought maybe i needed another one? So I ordered another one

Using the system for vocals and Yamaha N1X Piano. Excellent sound, very portable, and extremely fast to set up. I do recommend getting the Bose T4S (or T8S) Mixer to optimize the system. Without the mixer the standard adjustments are not flexible enough to achieve a studio sound during live performances. With the mixer the system is absolutely phenomenal!

Needed this
In my opinion, pianos just don't sound good when played in mono. They sonically sound fine but lifeless. So I always play in stereo. I'd been using my Bose L1 system but you know that's mono, so I've been using a pair of Bose S1pros. The piano sounds great in stereo. I created some basic drum and bass backing tracks to support my solo performances so I can at least sound like a trio, but those were lacking low end with just the S1pros. Adding this little sub fixed that, it was just what I needed. Josh Kattner at Sweetwater made it happen, he is my go to guy for all my gear needs. A true pro
