Shrink Totem 1's?

Hello 

New here. I have a pair of Totem 1's which have been in storage for a few years, in order to get them to fit on my bookshelf I plan to cut them with table saw and take about 4" of depth away. These are rears and space is limited.  I have low expectations on the outcome but I'll keep this post updated as what materializes with this project.  PS these are about 5/10 condition so not too worried about the outcome. Also fronts and center are all Totem (in better condition). Wish me luck. Thanks
