Bose® 251® environmental speakers
Our take on the Bose® 251® environmental speakers
Take sturdy, weather-resistant outdoor speakers. Provide them with angled drivers in a unique Articulated Array® design that reproduces sound over a larger listening area. Then add top-notch Bose audio technology, with patented multi-chamber bass enclosures for deep bass without audible distortion. The result? Bose 251® environmental speakers and a whole lot of outdoor music enjoyment.
These innovative speakers can withstand temperature extremes from 158º F to -40º F, and passed the rigorous salt fog test 66% longer than required by the Marine Industry Standard. That means they can handle direct exposure to the elements so they make just as much sense for your dock or boat as they do for your patio. And with weather-resistant mounting brackets and hardware included, and a 5-year warranty, you can count on years of groovin' in the great outdoors.

Drivers: The Bose 251 environmental speaker features a 5-1/4" woofer and two 2-1/2" Twiddler drivers with ultra-durable, polymer fiber composite cones built to withstand temperatures from a blistering 158° F to a frigid -40° F. Additionally, the speaker can withstand salt fog, sun, high humidity (100% RH), vibrations and mechanical shock.
Articulated Array Speaker Design: By precisely positioning the drivers inside the speaker cabinet, an Articulated Array speaker design can provide a large, consistent sound field. This allows for a more even sound coverage with these outdoor speakers.
Water-Resistant Cabinet: Engineered with a water-resistant, weather-tight polypropylene housing, these speakers provide extra durability through extreme weather conditions and still deliver great high-fidelity sound. For additional protection, the speaker uses a galvanized, powder coated steel grille.
Multi-Chambered Bass Enclosure: Uniquely structured, the chambers within this patented design filter out unwanted audible distortion in the low-frequency range. They also improve speaker efficiency, resulting in deeper bass from a small enclosure.
5-Way Binding Posts: The nickel-plated brass 5-way binding posts will accept bare wire, pin connectors, spade connectors, banana plugs, and dual banana plugs.
Mounting: Weather-resistant mounting brackets are also included to allow for easy installation. The speakers can be moved up and down in the mounting brackets, allowing you to position them for optimum imaging.

6 questions already asked
No. Hard wired. [ Joe Jun 13, 2016 ]
No they require wire [ DAN Jun 13, 2016 ]
No. You can only connect them with speaker wires. [ CHARLES S Jun 13, 2016 ]
I live in Rockland County. NY where the temperature gets below freezing in the winter. These speakers can withstand cold temperatures so I do leave these Bose speakers outside all year long. [ CHARLES S Dec 26, 2015 ]
I did take them down. I didn't see any need for them to suffer through the weather. Mine were in an easy place to get to. I'm in northern NY. [ Alan Dec 26, 2015 ]
I really don't know. My Bose-251 speakers are mounted outside on my deck exposed to the weather and do fine. I had a previous set of Bose-251 speakers outside on my deck for over 15 years with no problems. They started experiencing issues last year so I bought a new set. I am not sure about the effects of the marine environment salt water etc. [ David Apr 04, 2017 ]
Speaker wire. They will not connect directly to a phone or mp3 player. They must be hooked to an amplifier via speaker wire. [ John Jul 18, 2016 ]
The don't need a Bose amp - just regular speaker wire hooked up to a receiver or external amp for a second zone. Powerful speakers that disappear on a house with white trim boards. [ CHRISTOPHER Jul 15, 2016 ]
They run off of whatever wattage your receiver is sending them through the speaker wire. [ Eric Jul 15, 2016 ]
I actually returned these speakers as I decided to get Rock speakers instead. I am not sure I understand your question. These would be connected via speaker wire, but would need some sort of power source, ie Sonos Connect Amp, or to be hooked up to your receiver. They are not self powered if that is what you were asking. [ Andrew Jul 15, 2016 ]
Just 18/2 speaker wire to a basic Onkyo amp. They're on my friends huge house facing the water. The sound is unreal, you will not be disappointed. [ jamie Jul 15, 2016 ]
You definitely need an amplifier. [ John May 07, 2016 ]
You definitely need an amplifier. [ SCOTT A May 06, 2016 ]
They require an ampliier or receiver. Yes [ Jon May 06, 2016 ]
Yes, The bigger the better, I'm throwing 140W per channel at them. FYI, you might want to pick up a subwoofer as well, they don't have much base. Look at the JBL Xtreme speaker on here if your looking for iPod outdoor'ish speakers. [ Eric May 06, 2016 ]
It gives you the dimensions right on their website 4 & 9/16 inches tall 12 & 5/16 inches wide 6 & 1/16 inches deep [ Bagel Works, Jul 25, 2016 ]
not sure i understand the question, the size is shown , i have 3 sets . 2 on porches and one set hung off my roof over hang . they work great and cover large areas [ Jon Nov 23, 2015 ]
