Bose 901 Series ii

i have 4 901's. i have 2 for the front and 2 for the sides. this is what was called the "super bose system" back in the 70's.

Stack enough of them and you'll have a version of the typical live concert line array.  Insanely loud, and capable of accepting more power than your home wiring can handle.  Can break any lease that any fool would let you sign.  Would bring the local PD to your door not long after you turned the knob past 5.

Probably would funny as hell to try Once.  It would take awhile for your ears to recover and to repair all the cracked plaster and/or rippled sheetrock.

Let me know when you plan to try this.  I'll come with a chair, cooler, and umbrella to watch from a safe distance...;)

i was told by a mcintosh dealer that allthough the 901's are rated to handle 270 watts, if you have 4, 2 per chanell, that does'nt mean it will handle 540 watts. this would apply to the original and series 2.

No. You'll have nothing like a modern line array no matter how many you stack up. A line array is a hell of a lot more that stacking a bunch of crap speakers in top of each other. Line array cabs and drivers are specifically designed for that purpose because the drivers need to be properly aligned from one cabinet to the next. If that proper alignment isn't achieved, you don't have a line array. You have a tall pile of garbage that's going to exhibit severe vertical comb filtering due to the source behaving in an incoherent way. 

kosst, granted....given the 901's design and intent, a stack of them would not be a 'perfect' line array.  It would be louder 'n hell but would exhibit all sorts of warts doing so....

Noting that a concert venue's arrays typically have a curvature, no doubt to minimize if not eliminate combing.  That, and they're meant for coverage and penetration of a large area, much larger than that of a 'typical' suburban listening space.  One might try that with a stack of 901's, but I've got my own predilections to play with and don't really have the desire to follow up on that...;) 

Given your comment, I'd suppose the bulk of 'line arrays' on the market (the tall, thin units with multiple small drivers) could be considered feces.  It would seem that combing would be impossible to avoid with them, which would really appall their owners.  Those who find them attractive no doubt like what they hear. *shrug*

Sets up an interesting conundrum, don'tcha think?  You either like it or you can't stand it.  Starts to sound like a lot of the equipment 'discussions' that become superheated on these pages, IMHO...

...as 'wrongheaded' as they may be...

Not trying to pick a fight with you, BTW.  Just observation and response...
