    Comments about Eminence Commonwealth 12" 225W Guitar Speaker:

    I put one of these in a 2x12 cab and I was not disapointed. I had been shopping for a JBL but I didn't want to pay a lot of money for a used speaker so after doing some research and reading Emminence's website I decided to try the Commonwealth. It sounds so good I forgot all about wanting a JBL. If you've ever heard JBL's this speaker is as close as you'll ever get. If you read Emminence's description of this speaker it is spot on: Loud,great presence,punchy and warm with good clear highs. It weighs a lot but it's worth the sound.

    Excellent Speaker

    By Mckyhart

    from Miami, FL

    Comments about Eminence Commonwealth 12" 225W Guitar Speaker:

    I love it. It's pretty heavy, so anyone considering it for a 2x12 ought to have a young, strong back, and anyone considering it for a 4x12 ought to consider selling the 4x12 cab and buying a couple 2x12s. Unless you have roadies, that is. Even in a 1x12, it's good and heavy. But the sound is worth it; you can't get alnicos to sound like this. It's a magnificent speaker (far better than the Emi Red White and Blue that it replaced -- the RWB sounds like a cheap knock off compared to this), and I recommend it strongly to anyone looking for a well-rounded, versatile tone machine.
    Features are everything they should be -- aluminum dustcap for those beautiful, ringing highs, a big ol' ceramic magnet for warmth and a well-designed cone for a well-balanced sound.
    Construction quality is solid, the packaging that Eminence speakers come in is plenty protective, the leads felt like they could have been a bit sturdier, but they didn't feel flimsy, either.

    The sound, though. That's where this baby really shines. As I wrote in the "Features" section, the warmth in the mids and bass (a warmth that never crosses into unpleasant boominess or lack of clarity), the shining, bell-like ring from the aluminum dustcap, and a pleasant balance of sound are all wonderful. It sounds very nice at low volumes, and it just sings at high volumes. It's at its best when a good deal of air is being moved by it, but it's still a lot better than any other guitar speaker (compared to other vintage JBL or Fender-style speakers) that I've played through even at lower volumes, and that includes the JBLs in an all-original 1967 Fender Super Reverb and an all-original '61 Fender Concert.

    If you're thinking of getting a JBL for a Jerry sound or other vintage sound, this is a speaker worth seriously considering. For country players, psychedelic rock players, and anyone who wants a perfectly balanced, beautiful-sounding driver, this is a speaker worth seriously considering. Not gonna tell you what to buy, since it's all subjective, but if I could bring you to my house and let you play through this speaker, I would. It just sounds so good.
    Considering that an original or original recone kit JBL will run you around twice this price (and considering that this is a new speaker that, while not as exclusively treble-heavy as the JBL, has all the sparkle and clarity of it and more versatility in its mid and bass reproduction), this easily rates a "10".

    The Finest Replacement Speaker

    By TKHIGGS

    from Center Point, AL

    Comments about Eminence Commonwealth 12" 225W Guitar Speaker:

    In all my years of playing guitar, I've never been more pleased with a new speaker. Yes, this monster is heavy... but it's worth the load. The tone is deep, firm, and wide. The lows go below 50k, the highs past 5,oook. The highs are clear and pure. This is the IDEAL speaker for a modeling amp like a Line-6 or Vox Valvetronix. This speaker does everything. With its outrageous power rating, I'm not even afraid to plug my bass into it. It's worth the price. I love this speaker.

    Looking for JBLD120 , here you go.

    By Anonymous

    from Undisclosed

    Comments about Eminence Commonwealth 12" 225W Guitar Speaker:

    If your looking for a JBLD120 and don't want to spend a fortune, here you go. I love skynyrd and southern rock alike, and wanted the sound of it. I went out and bought a peavey mace and a matching 2x12 cab. I replaced the speakers with these, oh my god! I also play a peavey classic 100 head through them. Oh my god these are great for southern rock/rock. Buy them now before something bad happens and you can't get them again. Thanks.

    Absolutely INSANE

    By IbanezRGuy

    from New Kensington, PA

    Comments about Eminence Commonwealth 12" 225W Guitar Speaker:

    I've always been disappointed with guitar speakers, small voice coils, small magnets, and low power handling...UNTIL NOW!!These things are absolutely ridiculous. 4" Voice Coils, HUGE magnet, 225w RMS Power Handling. Almost a subwoofer but with sweet midrange and so-so highs. I loaded two of these in my 4x12 Mesa Cab with 2 stock speakers. INSANE bottom end! I wouldn't want only these speakers, just because the tone isn't all there from what I can hear, but the bottom is. The way I run my setup anyway is I have these on the bottom of my cab, and on one channel of my power amp, and the other two on the top and another channel.
