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.

Driver Technology

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.

Enclosure Design

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.

Connections

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 Options

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.

i love bose [ denise  Jun 23, 2018 ]
A
I chose the 251 due to their unique physical form factor. While this is surely not how to choose audio equipment, other models I was considering sounded similar. In fact, the 251s sounded better than most, but I had a unique location where they would be mounted. I found the 251 mounting brackets to be more usable than the others and the vertical orientation was perfect. Great design, and the great sound is included. [ Richard  Jun 16, 2018 ]

Q
How do I power these? I am connecting lights through a 12v transformer. Can these draw enough amps from that current or do they require 110v?
[ Laura  Sep 07, 2018 ]
1 answer
A
No AC or DC power required. You just plug nbyour speaker wire that connects with a normal audio amplifier.
[ Scott  Sep 08, 2018 ]

I put 4 in a 20 x 25 pool house patio. They sound awesome. You won't be disappointed.
[ STEVEN  Feb 19, 2018 ]
A
Two would be plenty. I have two mounted on my shop which 40 foot wide when you turn the volume up. You can hear them over 100 feet away.
[ travis  Feb 19, 2018 ]
A
Two will work, but four will work better, assuming your receiver can do a true 4 speaker. They sound fantastic (2) in our metal building used as a weight room. 60 x 40
[ Rheynard  Feb 19, 2018 ]
A
2 is more than enough. They are wide angled sound proj
[ ROGER  Feb 19, 2018 ]
A
Should be fine with 2 provided you have a decent enough receiver driving them. I have 2 for a 30 by 30 pool deck and they are more than sufficient to lay a good beat down
[ daryl  Feb 19, 2018 ]
A
I only have two!

My backyard is almost 1/2 an acre and it fills my yard with sound.

Q
How many 251 speakers would I need for a 40' by 60' area?
[ JFloy  Nov 13, 2017 ]
3 answers
A
Depends on how loud you want I guess. They have no bass sound to them. But are excellent out speakers. I have 4 on my shop. Two facing the driveway and two facing the backyard. They can be heard from over 100 feet away at 3/4 volume.
[ travis  Nov 14, 2017 ]
A
4 - it would give you great sound in entire area.
[ Kim  Nov 14, 2017 ]
A
You need only four speakers to provide an optimal sound.
[ chris  Nov 14, 2017 ]

No. You can only connect them with speaker wires.

Q
live in the northeast - should i take these in during the winter? thanks
[ thomas  Dec 25, 2015 ]

A
I live in Tennessee where the temperature can be 105 or -5. I have had a set of 251 exposed to this climate for 10 years without any issue. Love these speakers.
[ Kim  Nov 14, 2017 ]
A
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 ]
A
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 ]
Q
will these work for the front of a sailboat exposed to heavy weather? are they that weather resistant?
[ Sanjay  Apr 04, 2017 ]
1 answer
A
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 ]
Q
Do they need a power source, or run off speaker wire?
[ Joe  Jul 14, 2016 ]
5 answers
A
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 ]
A
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 ]
A
They run off of whatever wattage your receiver is sending them through the speaker wire.
[ Eric  Jul 15, 2016 ]
A
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 ]
A
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 ]
Q
Do I need an amplifier with these speakers or can I connect my iPod to them directly?
[ Lori  May 06, 2016 ]

A
You definitely need an amplifier.
[ John  May 07, 2016 ]
A
You definitely need an amplifier.
[ SCOTT A  May 06, 2016 ]
A
They require an ampliier or receiver. Yes
[ Jon  May 06, 2016 ]
A
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 ]
Q
What dimensions per speaker?
[ Raymond  Nov 21, 2015 ]

A
It gives you the dimensions right on their website 4 & 9/16 inches tall 12 & 5/16 inches wide 6 & 1/16 inches deep
