These are the most sensitive speakers, loudest on the market, so these speakers will allow you to have more volume, ideal for those who have low wattage guitar amplifiers.

Increasing the volume of the amplifier:

If you have a low wattage amplifier, for example less than 20 watts, this guide is ideal for you. This is a list of the 10 most efficient good quality 12 ″ guitar speakers, giving you more volume at the same wattage level as your amp. Even with a speaker change, you could make your amp sound as loud as a rig with twice the power. It sounds incredible, but it is.

How do you measure the sensitivity or efficiency of a speaker?

The measure to express the efficiency or sensitivity of a speaker is in decibels, thus expressing the ability to translate power into Sound Pressure Level -SPL-. The higher the dB rating, the louder the guitar speaker will be able to deliver. For reference, 12 “speakers typically range from 96 dB to 103 dB.

Volume: amplifier wattage and speaker sensitivity

The efficiency factor of your speaker indicates the ability to transform the amplifier’s power into sound pressure. Thus, a speaker with higher sensitivity or efficiency will give you more decibels or volume with the same amplifier than if you use a less efficient one.

When you have a low power amplifier, using a more efficient speaker will allow you to have more volume. You can also get cleaner audios, as you will need to demand less from the amplifier to achieve the same volume or sound pressure level.

Thus, putting a speaker with 3 more decibels has the same effect as doubling the power of the amplifier. So, if you have a 10 watt device with a 97 dB efficiency speaker, if you change the speaker for a 100 dB one you will have the same effect as if you double the wattage, and if you put a 102.8 dB speaker, which is the most efficient from the list, the effect would be to almost quadruple the power of the amp.

The more sensitive speakers, the more volume they have.

Amplifier Power Equivalences and Speaker Sensitivity

For reference, each of these groups generate similar sound pressure levels -SLP-:

Equivalences between amplifier power and speaker or speaker sensitivity / efficiency.

Thus, with a 25 watt amplifier with a 103 dB speaker sensitivity you can sound as loud as a 100 watt amplifier with 97 dB speakers, which is the sensitivity of the Celestion Creamback G12M 65 or G12T-75.

As a reference, a team with low efficiency are the Celestion Creamback G12M 65 and G12T-75 with 97 dB or the Greenback G12M or the V-Type with 98 dB.

About this list of guitar speakers

The list has been determined by checking the specifications on the websites of each of the brands, reviewing each of the models. It is ordered in descending order, that is, from most efficient to least.

All the speakers are Eminence as this company builds speakers very efficiently. However, as our idea is to provide a wide range of options, beyond which are the highest volume, at the end we indicate which are the most efficient from Celestion and WGS, in case you like those brands more.

Top-10 of the most efficient guitar speakers

Eminence Wizard – 102.8 dB

Eminence Wizard, the most efficient speaker, with more volume.

This is the loudest volume guitar speaker we’ve found from our survey. The Wizard is an English speaking speaker and is part of the Red Coat range.

The Wizard has sweet tones in the low frequencies, but also has good highs. The Eminence Wizard is a great option for someone looking to add a bit of treble to their sound. 

The Wizard works well on amps like the Blues Junior, Hot Rod Deluxe, Peavey Studio Pro 112, Marshall Valvestate amps, and many others.

Eminence The Governor – 102.3 dB

Eminence The Governor, one of the most efficient speakers, with more volume.

The Eminence Governor speaker features sweet but punchy bass. This means that the low frequency response is more focused on the lower mids than that super low-end sound.

Although the Eminence Governor speaker is very efficient, it also saturates early. If you like the distortion of the speakers a bit in the character of your audio, this is a great pick.

Although it is part of the Red Coat series, its tonal character will suit those looking for a great speaker without the excessive treble or bass frequencies. This is really a great powerful speaker that will suit anything from blues to rock.

Eminence Hempdog – 102.3 dB

Eminence Hempdog, one of the most efficient speakers, with more volume.

The Eminence Hempdog was produced for guitarist Pete Anderson. Designed to be a combination of Pete’s two favorite speakers. It has a warm Cannabis Rex character while also having a fairly balanced frequency curve, providing a neutral and clean tone like the Legend EM12.

This is a very nice and well balanced speaker for someone who wants to keep their amp character intact. The Hempdog accommodates both Fender and Marshall tones, and will also be a great way to tame the high end of a Vox.

Eminence CV-75 – 102.2 dB

Eminence CV-75, one of the most efficient speakers, with more volume.

The 75-watt Eminence CV-75 speaker boasts an unmistakable British tone. It has a complete tonal balance: strong in the lows, warm mids and pleasant, clear and open highs.

The Eminence Swamp Thang is a speaker from the Eminence Patriot series. Designed for heavy guitarists looking for full-bodied audio. Provides a thick and sustain tone. The bass responds well to 7-string guitars.

Another feature of the Eminence Swamp Thang is that it will keep its top end nice, clear and bright. 

Eminence Cannabis Rex – 101.8 dB

Eminence Cannabis Rex

The Patriot Series Cannabis Rex has an American character, which makes it an excellent choice for use in Fender amps such as the Blues Junior or Super-Sonic 22.

Eminence Tonker – 101.5 dB

Eminence Tonker

The Tonker speaker is powerful, it has 150 watts. An outstanding feature of this speaker is the large headroom it has. What this means is that your amp will stay cleaner at higher volumes. The Tonker has more rounded bass than the Texas Heat or Wizard, and it defines well through its high frequencies.

It features top mids that cut well into the mix. If you want something sure to sound strong, this is an option to consider.

Something to keep in mind is both the weight and the size of the speaker. The Eminence Tonker is very heavy and its magnet is huge. Make sure you have enough free space for this speaker on your amp.
