Your next outdoor BBQ will rock the block with our BOM4.12 4.1 Bluetooth®-enabled outdoor subwoofer/satellite system that goes beyond bass. This flexible audio system includes a 4.1 digital amplifier to connect additional outdoor speakers for a true, acoustically balanced outdoor audio experience. The 8” subwoofer enclosure includes a 360-degree omni directional design for easy placement, and the BOM4.1.2 is Bluetooth®-enabled so you don’t need to run wire from your audio source to the subwoofer. Simply pair it with your tablet or cellphone for wireless control of your music library or streaming services. Two stereo outputs and a separate digital amplifier allow you to connect two pairs of landscape speakers or satellite speakers for full coverage and maximum volume. Designed with all-weather components including an IP67-rated power supply that is guarded against cold, hot and wet climates, this durable outdoor subwoofer includes an antique bronze cabinet that blends effortlessly into backyards and eco-friendly landscapes. 

Beyond Bass and Bluetooth®
The BOM4.12 does more than just add rich bass and outdoor subwoofer and includes a 4.1 amplifier to add additional speakers. Building your system around a dedicated powered subwoofer can pump up an outdoor sound system to surprising levels because the subwoofer creates the foundation for a complete outdoor audio experience. A subwoofer is a dedicated bass speaker designed to handle the low frequency effects in audio systems and is the .1 in a 2.1, 4.1, 5.1 or higher surround sound system. In addition to delivering those spine-tingling bass notes, a subwoofer allows other speakers in your configuration to produce the frequency ranges they were designed to produce more efficiently. The result is less frequency roll off and more balanced and rich sound so the next time you’re in the hot tub, backyard or pool, the music will conquer the ambient noise.

What Is IP67 Rated? 
If you’re investing in an outdoor speaker, be sure that claims of waterproof or water resistance are backed up with an IP rating. IP67 is an International Protection Rating given to products that meet certain criteria. The BOM4.1.2 includes an IP67 rated power supply that is 100% protected against solid objects like dirt, dust and sand and has been tested to work for at least 30 minutes after being immersed in water. This is important in backyards with pools and sprinklers where splashes can damage or short out the power supply.

Bluetooth® Flexibility
Every environment is different, but we've tested our outdoor Bluetooth® subwoofer unobstructed up to 75 feet and receive a clear audio signal. Your environment may have trees and other factors that can inhibit Bluetooth® transmission but line-of-sight transmission is generally between 35 and 75 feet, and pairing takes only a few minutes. Be sure the Bluetooth®  device and the speakers are turned on and fully powered or fully charged. Bluetooth® controls are typically found in the device's Setting or Connections menu. The speakers will output a Bluetooth® Sync code that will be received by the Bluetooth® device and settings such as volume, mute, etc., are controlled directly from your phone, tablet or other Bluetooth®-enabled device.

What's on your mind?

Brian D Fulton • 04/30/2021, 9:04:57 AM I have two OSD rock speakers and was thinking to add this wireless sub. I currently have the rock speakers hooked up to a Sonos amp and I'm concerned the two different technologies (wifi Sonos amp and bluetooth speaker) won't mix well. Can you advise?
Customer Service • 05/03/2021, 12:12:26 PM
Hi Brian: Unless SONOS has an option to transmit with Bluetooth, they will not work together. The ALEXA Echo Dot has an option to become a Bluetooth Transmitter and will sync up with the 4.0.2 or any of our Bluetooth speakers. Are you connected to the newest SONOS series amplifier (125Watt)? Both the new amp and older SONOS Connect Amp will play two pairs of speakers, plus they have a dedicated subwoofer output, so you could add our SMP200 Sub Amp and our FORZA8 to duplicate the Subwoofer setup of the BOM4.1.2.

Marcin • 05/10/2021, 9:37:49 PM The manual does NOT say anything about burying the BOM4.1.2 in the ground. Please provide clear instructions on how deep should the sub be in the ground. Thank you

Hi Marcin: Since the BOM 4.1.2 features a down-firing 8.0 woofer design, you can bury the enclosure right up to the bottom of the output vent. I personally would leave about an inch below. You want to be able to stabilize as much of the enclosure as you can. TL/5-14
Colleen Ryan • 05/15/2021, 9:25:11 PM I have 4 pair LS2's 8 speakers total already installed. I had a problem last year with the older model bluetooth sub stopped working. you gave me a full refund. I received this last week, is there going to be any problem connecting this to the 8 speakers I already have in place?
Customer Service • 05/18/2021, 3:11:31 PM
Hi Colleen: The BOM 4.1.2 has the same sub amp and two stereo amps (each to drive two pairs of LS2). The new enclosure features a down-firing 8" sub that no longer is a debris collector, so there is no heavy mesh grille cover needed like the previous BOM4.1. TL/5-18-21
desiree • 05/25/2021, 10:05:34 PM We are looking to add a bluetooth/wireless receiver, yard and patio speakers to our back yard. We want to be able to have zones and hear the tv through these speakers. Is this an option?
Customer Service • 06/07/2021, 1:22:01 AM
Hi Desiree: I believe it depends on your TV; it must broadcast a Bluetooth signal to the BOM4.1.2 internal Bluetooth receiver. Check the owner's manual of your TV. Otherwise, it will sync up with your phone to play music. It has an 8.0" down-firing Subwoofer enclosure with a Bluetooth receiver built-in plus a 100Watt Subwoofer amplifier and two 60 Watt stereo amplifiers that both hardwire to a pair of 4-ohm speakers or Two pairs of 8-ohm speakers for each amplifier (potentially 4 pairs connected to the Enclosure with an 8" subwoofer. It works best with our RX550 rock speakers or LS3 Pendant Landscape speakers. Good luck, TimL/6-6-21
