I found that it works well.. But can't say direct comparison wise, because fact is the only reason I have had to move them out of the cabinet was physically if your gonna use the Best parts available they are literaly 5 times the size of a cheap computer grade board and parts in most of these designs... For example, I did a pair for a friend, they had about 5" X 3.5" x 1.5" boards that maybe weighed 1 lb or so.. Well the EXACT same values of caps, Inductors, Resistors etc.. Of the highest quality we could get our hands on took up a minimum board of 12"(1 ft) X 9", and had to take up about 5" Height on top of it.. So we had to move them to a dedicated cabinet that with those parts weighed about 12 lbs... They were decent sized Cubes for sure.
Even if you have the space to fit such a huge difference in size you could probably knock the speaker out of Volume specs for the drivers if they share a chamber with it. Just a point to make, but I keep it safe if your gonna do an actual upgrade then build them outside for ease of everything, and yes maybe vibration control will be an added benefit, but just pulling them out for fun, I don't know, I would probably not mess with it.
