OSD Audio's BOM4.1 All-weather Bluetooth® Subwoofer brings bass to your backyard, pool or patio so you can experience immersive audio even in noise-heavy environments. This is a beefy 100W outdoor sub is designed with weather-durable components, including an IP67-rated power supply that will last for years in cold, hot and wet climates. The BOM4.1 is also Bluetooth®4.0 enabled so no digging up the lawn or stapling cables through the deck. Simply plug it into an AC outlet and then pair this sub with your tablet or phone, and you'll enjoy the low frequency sound that's missing from your outdoor audio system. This is a great outdoor sub to add on to an existing sound system but also includes stereo outputs, so you can build up your outdoor audio with satellite speakers such as OSD LS2 landscape speakers.

  • All-weather construction with IP67-rated power supply 
  • Bluetooth® 4.0-enabled with up to 75 feet line-of-sight range (may vary) 
  • Includes a 100W power rating for small, medium and large backyards or patios 
  • Green enclosure blends easily into backyard
Why Add Dedicated Outdoor Subwoofer?
The subwoofer is a dedicated bass speaker designed to handle the low frequency effects in audio systems and is the 2.1, 4.1 or higher surround sound system. Adding a subwoofer is an extremely efficient and cost-effective way to improve otherwise thin-sounding outdoor speaker setups. 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.

What Does IP67 Mean?
If you're investing in an outdoor speaker, be sure that claims of water-proof 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 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 particularly important in backyards with pools where water can damage or short out the power supply.

Excellent Bluetooth® Range:
Every environment is different, but we've tested our Bluetooth® sub 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. 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.

David Grijalva • 03/06/2020, 4:56:11 PM Does the unit also have speaker inputs?
Customer Service • 03/26/2020, 3:06:59 AM
Hi David: The BOM-4.1 Bluetooth Powered Subwoofer with built Bluetooth Receiver and a 100 Watt dedicated Sub-woofer amplifier plus two (2) channel stereo amplifiers rated down to a 4 ohm load. It is limited to a single Bluetooth source wireless connection through the internal Bluetooth Receiver. There are no signal or speaker level inputs, only the two four conductor stereo outputs. Each stereo amplifier can power a single 4/8-ohm or 2 pair of 8-ohms speakers. You even have the flexibility to run a pair of Rock speakers off one a stereo amplifier and a pair of patio speakers off the second internal stereo amplifier. This four channel Sub/sat system was created so you could connect a minimum of two pairs of stereo speakers to one Bluetooth signal. All our other Bluetooth speaker kits from OSD are limited a a single pair of speakers (the master and single satellite. I hope that answers your question. TimL; #003
Jim • 04/27/2020, 7:27:09 PM I am currently using 2 wired Bose freesoace51 speakers. Using a Sony Bluetooth receiver. The speakers are about 50 ft from receiver Would your Bluetooth sub work for this setup without wiring anything ?
Customer Service • 04/28/2020, 11:55:09 AM
Hi Jim: It would depend if your SONY can transmit as well as receive. What do you currently have your BOSE connected to? If you could send a signal to the BOM-4.1 that would give you a 100 Watt sub woofer. You could connect from two to four pairs to the two built in 60 Watt per channel stereo amplifiers. TimL/4-28-2020
