    Comments about Celestion G12K-100 100W 12" Guitar Speaker:

    Everyone raves about the Vintage 30 and the G12T-75 for metal, but I bet most of those people are using those speakers in a closed back 4x12 cabinet. In a combo, I found the Vintage 30 and G12T-75 to be harsh on the high end and lack bass on the bottom. This speaker cures those ills. I know the Classic Lead 80 a/k/a Black Shadow type speakers are popular with Mesa Boogie combos, but I always thought they sounded boxy. If you like a little more scooped tone, the G12k-100 is the way to go. I think it's the best speaker for a high gain combo.

        I ilke the G12H and V30 is OK too, but this is the speaker to use if you have an open back cab and need a little extra Bass, not as toned down as Greenback. but sort of like a mixe of a G12H and Greenback.

          Love these speakers. They sound great with my marshall mode four 350W cab and provide the low end and depth of sound that i wanted. They took a few days longer for delivery as they sat in customs for a week but that isn't really at fault for musicians friend.

            Comments about Celestion G12K-100 100W 12" Guitar Speaker:

            I needed a 16 ohm,100 watt speaker for a 1X12 so I can use my Marshall JVMHJS at band practice. (A 4X12 can't fit in my car & I don't have a 2X12) The result... great tone. The audio response is basically flat as far as EQ goes. This allows the tones of the head to really shine through. Sometimes it is good to have a speaker(s) that colors tone but not in this case. By itself this one speaker can EASILY handle a 100 watt JVM at high volume! I think I may get 2 more to put in an X pattern with the G12T-75s in my 4X12. Or maybe replace all four...

              Comments about Celestion G12K-100 100W 12" Guitar Speaker:

              Holy Cow these speakers amaze me.

              I had been looking to upgrade my cab for a while (an 80's Laney 4x12). I tried a Mesa Boogie with Vintage 30s and a few other Straight Cabs designed for metal.

              In the end I decided on a whim to replace my speakers with g12k-100s because of reviews and descriptions I had read. A little scary, but it totally paid off. The speakers give me the extra power/low end/clarity that I have been searching for!!

              I play through a Musicman HD-130 head, typically with fuzz, octave down and plenty of looping. My old speakers (gM-70s) got muddy quickly and never quite delivered the sub octaves the way my heart desired. the g12k-100s certainly deliver, and MORE.

              Also, they are relatively easy to install if you do a bit of online research and practice your soldering.

                This is a wonderful sounding speaker for classic rock tones. It is slightly scooped in the mids but this can be compensated for at the tone controls. The lows are big and tight and the highs are not harsh at all. Not nearly as scooped as the Celestion G12T-75. It handles a lot of power so it is great for a 1X12 combo or cab. It does clean sounds ok but really shines with crunch and metal tones. I would recommend it with the understanding that the midrange is less pronounced than the average "full range" guitar speaker.
