    Finally got around to finishing this. A few months back I bought a headless MG250DFX to refurbish and convert into a 1x12 speaker cab. I bought it to use with my DSL40C since there aren't a lot of options for 1x12 cabs that are as wide as the DSL. I put a G12T-75 in the cab and have the G12M-65 Creamback in the amp. I like how to two speakers compliment each other.

    All in I spent $135 USD:
    - $30 for the cab
    - $40 for a used UK G12T-75
    - $25 for the Birch plywood (new baffle)
    - $40 for grill cloth, piping, speaker jack & plate, etc.

    Side story - after I bought the cab and got it home I opened the back expecting to find low end MG speakers. To my surprise it had two V30's in it. My excitement was short lived, however, as one had voice coil rub and the other measures 7.3 ohms for 16 ohm speaker. I don't like V30's so I was hoping to sell them and pay for the cost of my project. Oh well.

    Here's what I started with - definitely has some miles on it.

    Cleaned up, Tolex repaired, and holes to mount the head plugged

    MG's don't have piping so I added it to match my DSL

    T-nuts glued and pounded in, logo and mounting holes drilled. Ready for sanding and painting.

    Thanks! The mix of the two speakers is definitely it’s own sound - for the better on my opinion. I’ve always liked the T75 so when I saw it on LetGo I jumped on it. The Creamback is a little warmer, more mids while the T75 brings out the low end. I’m not hearing the highs that some people dislike. I used to keep the DSL on a stand but now that the cab is on the floor I can feel the low end at much lower volumes.

    Next time I’m home alone I’m going to try and do some recordings. The only problem is I don’t have an SM57, rather a Samson Go mic. It’s surprisingly good for the cost but not the audio quality of the SM57 so we’ll see how it turns out.

    Here's an audio clip comparing the speakers. It's recorded with a Samson Go Mic so it's not the most accurate replication of the tone, but I think it captures the differences well enough. Also, I could only record the OD with the volume at 1 so the amp isn't really breathing at this point. There's a lot of detail in the description on YouTube.

    Is there a logic behind the off-centre speaker placement?

    Or were you leaving space to possibly turn it back into a combo at a later date?

    The speaker is centered left to right, but on the lower half of the baffle to make room for the logo. I bought it without the head as the guy was using it as a 2x12 extension cab.

    I keep threatening to convert my DSL into a head, and if I do I’ll make a new 2x12 baffle. I can’t use the 2x12 baffle from the amp as it doesn’t cover the entire front because of where the head used to be.
