I have two pair that are in a covered outdoor room that is 16 x 20 in size. The 251's use of two tweeters angled provides a wide sound field creating a great result for outdoor use. The sound is excellent even at low volume making it easy for my guests to both enjoy it and not have to talk over the music. One pair is installed high in the corner surrounded by wood which amplifies the bass. The other pair is surrounded by just air. Where they are installed makes a big difference as my two pairs sound very different when isolated offering an obvious lesson in acoustics. I use a pair of outdoor volume switches to balance them. I previously had them in another house where one pair were installed high covering a back yard and flooded a large area with sound. These speakers can play loud if need be. My experience with them in three different locations gives me a unique perspective in recommending them and attesting to there versatility . Few outdoor speakers will provide satisfying bass but if you have a choice of where to install, using acoustic common sense can aid in improving the bass. Mounted on wood vs. brick will change the sound, in corners vs open air.....etc. This is true with all speaker installations. Speaker reviews are subjective based on personal preference and expectations. These speakers are not bass monsters and their indirect tweeter array provides a wide sound that produces little fatigue. Auditioning any outdoor speaker outside of its actual installation is nearly a useless exercise. This model has now been around at least 15 years and obviously has been a good seller for Bose. I can say over the 13 years I have owned them, these speakers are durable, versatile and lived up to expectations at the premium price.

Quality Sound and Durable
I have had a pair of 251's on my deck mounted under the overhang of the roof for 12 years now and they still rock. They see -20 degree F up to 100 degree F temps over the course of a year. I think the trick is to minimize the direct sunlight and moisture that hits them and they will last a long long time.

Tried and Tested, and Still Sounding Great!
We bought a pair of these speakers 16 years ago, attached them to the back of our house under the soffits, and they still look and sound just as great as they did when they were new! We listen to a wide variety of music while out on our deck and in our yard, and we can enjoy it without distortion throughout the yard, but without being too loud and bothering our neighbours, because the clarity of sound is fabulous. We live in southern Ontario, so these speakers have endured sun, rain, freezing rain, hail, high winds, snow, and ice storms. We have done nothing to them except occasionally wash off the grills in the spring. Highly recommend these.

The best speakers for boats!
The sound from these are 251"s are amazing, I recently installed them. I plan on buying more now! My brother has these aboard his Alaskan gillnetter in ice, snow, pounding rain, sea water spray, and serious cold weather. They always sound great, and have never failed. I strongly recommend them.

Quality throughout!
I bought 2 pairs of these speakers about 10 years ago.... bottom line they are bomb proof and sound as good today as they did on first install. I have them mounted externally on my rear garden house wall. Only thing I've ever had to do was clean out a few spiders but they sit there come rain, snow, wind or sun and pump out the music... Fantastic product.

Simply Amazing!
Bought these speakers 4 months ago. I have always bought bose products, so when the time came when I needed outdoor speakers, of course I looked at Bose. As I researched the 251 and came across a few negative reviews. These made me doubt a little and started researching other speakers. After a while, I came back to the Bose 251 and the Bose amplifier and finally made the purchase. I installed them with the included brackets outside my house, and downloaded the Bose app.Played some music and the moment the sound came from those speakers I asked my self how I could ever have doubted Bose. The sound is absolutely incredible. I have no idea what any reviewer could have found at fault with these speakers other than perhaps the price. What I say is you are paying for quality and that's exactly what you get. Their size is perfect. The sound and the base are crisp and rich. Everyone that comes to my house marbles at the sound that comes out of these speakers. So glad I went with my heart. Thanks Bose for another great product.

These speakers are the TRUTH!
bought these from the Bose store in Williamsburg. Ive always had Bose speakers throughout my life due to a family with musical backgrounds and the need for precise sounds. I was skeptical at first. I didn't think these would sound great outside. I gambled and it paid off. I installed them about 10' apart just underneath the soffit to help protect against rain. These speakers sound absolutely AMAZING!. I hooked them up to a old Kenwood receiver. Our backyard is 165' long and 85' wide. Turning the volume to 2 and you can have crisp clear sound and hold a conversation with someone 50' away. I turned it to 4 and it was even more amazing of the sound all the way to the back of our property. I then tried 6 and I feel like im at a rock show. I think where they are mounted helps as well. Thinking the sound bounces off the siding and reflects towards me helps . I thought I was going to need 2 pair but this 1 pair is plenty. Bose knows they have a great product. This is why the design hasn't changed in years. Trust me, as a 30 year musician , these are what you need for your backyard.
