Roland Cube 80XL Pine Cabinet Conversion

After building pine cabs for my Vox VT50 and my Peavey Bandit Red-Stripe I have decided to do the same for my Cube 80xl.
I try to build the combo cabs exact or close to stock so I can use all corners and parts of the stock amps plus the stock amp covers will fit.
Now the stock cube 80xl uses 1/2 or 9/16 inch particle board plus tolex which makes the sides about 5/8 thick. For this project I will be using 3/4 pine. I will make the inside of the cab the same dimensions as stock so the amp will be about 1/4" larger than stock in height and width.
I have cut the top, bottom and sides glued and screwed , let dry remove the screws, drill out then glue wooden dowels in their place.
Pics show the completed Vox , Peavey and Roland progress so far!

 

While I am working on Roland cube 80xl. I am wondering if anyone has converted one to an open backed cab or done a speaker swap.
I plan on opening the back or installing a removable panel.
But I may upgrade the speaker if anyone has done so ,I am open for suggestions.

 

Finally had some time to continue.
Framed out the face with some poplar which tends to take the stain a little lighter than pine.
Cut a plywood speaker baffle using 3/8 ply was planning on using 1/2" ply but I am not concerned with strength cause it's such a small area 14 3/4" x 15 1/4".
Still deciding on open or closed back and whether to change the stock speaker.

 

Roland Cube 80XL pine cab finally finished. Be so busy haven't time post as it was happening.
I couldn't use the roland's corner protectors cause the wood I used was only 9 1/4" wide the roland's are about 3/16" longer. So used aftermarket corners. Made it open backed and sounds good but need to use it on a gig to really judge but Lord knows when that will be.
Probably 5-7 lbs lighter.

 

Thanks, removing the screws and drilling out and glueing in wooden dowels is actually very strong and allows the rounding of edges without hitting screw heads. One of these days I'll get a dovetail jig though.
