It's debatable how necessary 45's are needed for daily use but all in all it doesn't hurt.

 

As long as your 45's aren't gigantic they don't take up much space at all, if you're worried you can calculate it using  you can use this website to calculate bracing you can also use this to calculate the brace volume http://www.hometheatershack.com/forums/enclosure-volume-calculator/

A 45 degree triangle has exactly half the area (and therefore volume) as a square of the same size.  Square area is Length x Width (volume then multiply it all by Height)...to convert to a 45 triangle cut it in half.

45s were a big thing not too long ago but lately I haven't seen to many enclosures built with them.

I havent seen an enclosure gain from 45's in years.  Pointless and a waste of time imho. If your competing, i would test without and with,...... but, i have never seen a gain using them. Ever.  Bracing, ... im a fan of. 45's, i wouldnt even put a second thought in them, if it was me.
