A lot of guitar players out there don’t always think about how each and every piece of their gear creates their amplified sound.

Everything from the pick you hold to the mic you put in front of your amp is part of what you sound like and are each pretty important.

One of the most important parts of your rig is the speaker or speakers in your cabinet. Everything before the speaker is colored by the speaker you choose and changing your speakers can drastically alter the sound of a combo amp or speaker cab.

In this article, we are going to take a look at some popular choices of replacement guitar amp speakers that you might like the sound of better than what you now have. We will focus on 12-inch speakers, as those are the most common for guitarists to use.

It’s important to understand a few basics about speakers before we start shopping, however.

First, impedance matters. Run an 8 Ohm head into an 8 Ohm cabinet. Some people like mismatching impedances but this can lead to disaster for your output transformer. Learn about Ohm’s Law to get all the gory details. This graphic will help, too:

It is also good to have an idea how much speaker distortion you’re after when buying new ones.

Old school Marshall cabs had 4 25-watt 12-inch speakers, which made for a lot of speaker breakup. Some people like that, some don’t. Use higher-wattage speakers with a lower-powered amp to get a tighter and more focused sound, especially in low registers. Pipe a fifty-watt head into a 75-watt speaker and that speaker will take all that power and beg for more.

Beyond this info, it all becomes a matter of personal choice and application. In other words, you’re on your own!

Jensen is the king when it comes to all things Fender, 60’s, and blues-related.

The Jensen sound is heavy in the mid frequencies, which makes it THE choice for many blues and jazz players. Rock and metal players tend not to dig these but, if you have a cool old Fender or another vintage amp that needs new speakers, these are the natural pick.

  1. Great article and I own a vintage 30, a Jensen 10″. old classic Celestion GH 30’s and many others but I think we need to make mention of another classic. No guitarist has heard it all until he has played through a single Altec-Lansing 15″ in a large cabinet (preferably with several open ports). Remember that this was standard for the old blackface Showman before the “dual” cabinets came along. Just my two cents….it’s a completely different animal….
