I ordered one HT-110 extension cab for my HT-5 Combo. The question is: can i later change 1x10 speaker with some 1x12? i have one V30 speaker at home, waiting to be put somewhere... once again this is only extension 1x10 cab... :roll:

I'm sure that could be made to work.

Hi, first post and all :D

It should be no problem to install a 12" instead of a 10", after all they do it in the newer cabs. I did a similar thing with my old Marshall MG15 and went from a 8" to a 10".

This is what I was going to change:
Here is the old speaker in position in the new cutout.
I removed the staples and set aside the logo and tolex for reuse. I screwed the baffle to a piece of wood in the workshop, and screwed a scrap of 18mm ply in the old speaker cut out to find the centre of the hole. The cut out for the 8" was 7", and 9" for the 10". Once I had found the centre I drew lines at 45 degrees to mark the alignment of the fixings, then sat the 10" on top to check it would fit. All was OK, so I used the router with a centre pin guide to open up the hole. I left some of the original baffle in place as this was where the Marshall logo sat. I reused the T bolts, ran them up finger tight + 1/2 a turn then dotted them with Loctite.

When I bought the Blackstar cab I swapped the stock Celestion for the Tayden, and fitted it into a dead MG cab that I had, and this is how it turned out.

Not a tricky job, take your time and measure many times and you'll be fine 8)

Interesting! I do own a HT-110 cab (with a HT5 head) and I am considering to change the 10" speaker for a 12" V30.

Any tips and ideas are very welcome.
