What’s inside the packaging?
Winner: Bose 151
The first thing that you’ll notice when you unwrap both the boxes of the outdoor speakers is that they come with a lot of mounting apparatus.
Inside the box for the Bose 151 SE, you will find things such as mounting brackets, lock washers, wall anchors, screws, and so on. The packaging includes two mounting brackets; two-bracket locking screws; six lock washers; four bracket-to-speaker mounting screws; four wood screws; four wall anchors for concrete mounting and lastly, one owner’s guide to help you fix the outdoor speaker.

5 Best Bose Speaker
How is the design?
Winner: Bose 151
Both the Bose 151 and Bose 251 outdoor speakers come in the classic color options- black and white.
The Bose 151 has a sleek and modern design, with the Bose logo positioned in the middle whereas the Bose 251 takes more a traditional speaker approach in terms of design, with the volume control at the side in the back and the logo positioned near the bottom in the front.
Although design is much of a matter of perspective, I think we can all agree that the elegant and contemporary exterior of the Bose 151 catches all eyes in the room without an effort.

What about the build quality?
Winner: Bose 151
The Bose 151 SE weighs heavier than the Bose 251, but is smaller in comparison. It has a height of 12.5 inches, a width of 4.5 inches, and a depth of 6 inches. It consists of three woofer drivers, which are composed of glass-filled polypropylene. The three woofer drivers have a size of 2.5 inches.
On the contrary, the Bose 251 which is lighter in size has a height of 13.5 inches, a width of 5.8 inches, and a depth of 8 inches. It has two woofer drivers which are around 5.25 inches in size. The woofer drivers are built of polymer fiber composite.
The disadvantage with the Bose 251 outdoor speakers is that it can only be mounted vertically to the wall. The Bose 151 is more versatile and convenient as an outdoor speaker since it allows for both vertical and horizontal wall mounting. Although it’s a bit heavier than its competitor, I’d say that the Bose 151 is better in terms of build quality since it is convenient to use.
What is the audio performance like?
Winner: Bose 251
Bose is known for its high-quality speakers but is the Bose 151 and Bose 251 worth it?
Both the Bose 151 and Bose 251 outdoor speakers have their exclusive technology incorporated in them. The speakers have what is called an Articulated Array design which works especially well for outdoor music. This special feature allows the woofer drivers of the speakers to be positioned in such a way that it emits clear and crisp sound for an outdoor setting. This means that your audio experience will be made much more pleasurable with exceptional surround sound.
Both speakers have the same impedance and sensitivity rating. Usually, a sensitivity rating of 88 dB is considered to be average for speaker sound quality. The difference, however, lies in the frequency range. The frequency response of Bose 151 is at 40 hertz to 80 kilohertz but the Bose 251 surely puts a lasting impression with a wide range of 10 hertz to 200 kilohertz. The Bose 251 also has a larger power handling capacity than that its competitor, Bose 151.
The biggest difference lies in the woofers of the outdoor speakers. Whilst the Bose 151 has three drivers attached to its woofers, the Bose 251 has two. Nevertheless, the woofers in Bose 251 are much larger which means that they have better base output.
When compared, the Bose 151 has the advantage of more drivers but the Bose 251 has a higher frequency range, power handling capacity, and larger-sized drivers. This ultimately goes on to show that in terms of audio quality, the Bose 251 is the winner.

Outdoor speaker buying guide
Here are some things that you should know before getting yourself the perfect outdoor speakers:
Types of Outdoor speakers
There are different styles of outdoor speakers available.
- Traditional outdoor speakers are the ones that are designed to include a weatherproof casing, corrosion-free wire connections, and rust-proof grilles, enclosed in a waterproof casing. These speakers are similar to indoor bookshelf speakers and are most commonly used.
- Landscape speakers are outdoor speakers that are built to hide in plain sight. These include teardrop satellite, simulated rock, mushroom, and bollard design outdoor speakers.
- Outdoor architectural speakers are those that are more visually appealing and offer a great sound experience.
- Line array speakers include multiple speakers that are mounted in a vertical line on a slight curve, a design that allows sound to be dispersed over a wide area.
How do you know which type of speaker to choose from? The line array speaker would be best if your outdoor space is large. If you have a large patio or a pool area, satellite speakers should be a good choice. However, if you have limited outdoor space, traditional speakers are the way to go.
Sound quality
The most important thing to consider before getting that outdoor speaker you’ve been looking for is how well it sounds. Because without a good functioning speaker, your outdoor party might not be fun.
First of all, if you are looking for the best sound possible you should determine the right cone size and wattage for space where you will install the speaker. Also look at the these Best Audiophile Speakers if you want have a knack for audio.
Usually, the more bass, the better an outdoor speaker sounds. If your backyard has plenty of space, you should choose an outdoor speaker that has a low-frequency response. This technically means speakers with larger cones, i.e. 6.5 or 8-inch cones, since the larger the size of the cone- the more bass it can offer. Find out more about some of the best bass speakers in Best vibration speaker.
Usually, the range of power for outdoor speakers is between 60 watts to 300 watts but the rating mainly depends on the power of the output of the receiver or amplifier that is used with the speakers. A greater wattage rating has the advantage of not only the speaker sounding louder but also covering a lot of distance for sound.
Setting up the outdoor speaker
It is very important that you know precisely about the environment in which you will set up your outdoor speakers. You have to clearly identify the position in which you will mount or place your outdoor speakers so that when buying them, you will know which size to go for and the number of speakers you’ll be needing. Here you can find some Outdoor Projectors also.
If you’re going for a wired speaker, you will need to make sure that the length of the wire is correct for the perfect placement of the speakers. Since the speakers are to be placed outdoor, wireless speakers will be a better option.
Lastly, make sure you have all the things you need to set up the speaker. Mounting hardware such as anchors, screws, knobs, and brackets are absolute necessities.
