Fifteen inch guitar speakers are less common than amps with 8, 10, or 12 inches in diameter. This goes for both combo amps and amp head with cabinet formations. But aside from these standards, you’ll also find some pretty “unconventional” choices—such as, as we’ve mentioned, 15-inch speakers.

Although you don’t see them that often, they come with some advantages. The most prominent one is the power and clarity in the bottom end of the audible spectrum. Since they’re bigger, they have more potential to reproduce those lower frequencies better with all the nuances. And even if you hit your guitar strings harder through a tube amp, you won’t get that “muddiness” in there.

Therefore, these are something that those bottom-end lovers would prefer. However, it’s not exactly the easiest task to find these speakers out there. This is why we did some research and so, without any further ado, let’s dive right in.

Here are our recommendations for the 4 best 15 inch guitar speakers on the market:

Eminence Legend 1518 15 Inch Guitar Speaker

We can’t help but stop at Eminence and their Legend 1518 15-inch speaker. Specially designed for the lovers of deeper guitar tone, this one’s capable of blasting up to 150 watts of output power. The most exciting part is that you’d get a lot of clarity with it, even with that fuzzy high-gain tone that’s popular among psychedelic rock or doom metal musicians.

At the same time, they still manage to reproduce a part of the higher end of the spectrum, which is a very unusual trait for these kinds of speakers. The item has solid durability and is capable of sustaining high volume, as well as a few shakes and light punches. We find this interesting as the price tag is fairly affordable, so definitely a plus there. These are among the best 15 inch guitar speakers for the money.

Eminence EPS-15C 15 Inch Guitar Speaker

Another one by Eminence, the EPS-15C is a bit of a different deal compared to the Legend 1518. These speakers are specially designed for lap steel and pedal steel guitars. Thanks to its aluminum steel caps, we can get even more of those higher ends in the equation.

To put it simply, these speakers cover a lot of areas. And although designed for lap steel and pedal steel guitars, it still does a great job for regular electric guitars. It’s a great choice for those who love heavier bluesy music. It’s also worth noting that EPS-15C handles up to 300 watts of output power, which is pretty impressive.

If you’re a rock or a metal guitar player that likes to rock out loud and crank it up to 11, this might be your ideal pick. They have a reputation of being solid as a rock too, so keep that in mind if you travel frequently with your amplifier.

Celestion G15V-100 Fullback 15 Inch Guitar Speaker

Celestion is a company that needs no further introduction. If you’re at least somewhat familiar with electric guitars, you’ll know how popular their guitar amp speakers are. For this purpose, we’re bringing in their amazing G15V-100 Fullback 15-inch speaker.

Compared to the previous two examples, this one handles lower output power levels, up to 100 watts. It can handle frequencies from 65 Hz and up to 4,000 Hz. Playing those clean tones brings a lot of warmth in the mix. At the same time, distorted tones come with very harmonically rich content, especially in the mid-level frequency parts. So if it’s clarity that you’re after, you should consider this one.

The speaker utilizes and eight hole chassis, allowing additional tonal depth to enter the mix. Another notable point is that the price tag is quite fair and affordable—hands down, one of the best 15 inch guitar speakers around.

Eminence American Standard Beta-15A 15 Inch Guitar Speaker

Finally, we’re bringing another Eminence, the American Standard Beta-15A to the list. Yes, this is a pro audio speaker for hi-fi amps. However, it can also do wonders for all those who prefer to play regular guitar with some additional bottom end in there.

This one can handle up to 300 watts of power, which is a true feast for doom metal enthusiasts. We’d recommend it to anyone who’s willing to experiment with unconventional equipment. This is also the cheapest product on the list, so if the sonic description suits you, you’re in for a top deal. Note that the speaker comes with an optimized frequency response, as well as power handling, which is what allows it to be used as a replacement speaker for a variety of sound systems, including guitar, bass, and keyboard amps.

In most cases, 15-inch speakers are a very popular choice for those who are only guitar players in the band. Of, if one of the guitar players in the band prefers to play with these kinds of speakers, they should be the only one. The problem is that things can get pretty muddy with two or more guitars implement them. This is especially the case if you’ve got a loud bass guitar in the band as well. While we’re at it, these speakers also come in handy if you’re playing in a band that only features guitars and no bass, as they would fill up all the “holes” in the lower end.

Any of these speakers that we mentioned above can do well if you love that bottom-end heavy tone. Of course, you’ll also need to consider the right type of cabinet for your needs. It’s worth noting that getting an additional 15-inch speaker can be quite beneficial and add an additional layer of tone regardless of the style you’re trying to pursue.

But whatever may be your choice, just take care of the wattage and how well these speakers will deal with your desired equipment. We hope that this guide was of use to you, that you’ve learned something, and that you feel more confident about making the purchase. Stay safe and rock on!
