How long untill I can really Flog them Hard

He damaged the speakers by plugging/unplugging an RCA input with the volume up.

Lets cut the guy a break (although he blamed his wife for the incident). Flog away.

I have the same question because I've got a new pair of paradigm studio 20's. I'm taking it kind of easy for 100 hours or so since I cranked my then new studio 10's on day 1 or 2, heard a pop then backed off immediately. After that, the speaker that popped would make that same popping / distorting sound that I initially heard, from both the midbass and tweeter, when turned up loud. By comparison, the speaker that didn't pop could be turned up 4 or 5 d.b.'s louder (according to the volume indicator on my pre-amp) and that extra 4 or 5 d.b.'s would have made a world of difference to me.

I heard a pair of 802 MATRIX speakers years ago playing Bruckner #9 (at an audio store), and the guy had them CRANKED!! to where the background noise (it was a remastered analog recording) was VERY noticeable. anyway, he stated to my worried face that you "couldn't blow these speakers". the Mark-2 version of these speakers had a protection circuit built in as well which was later eliminated to improve the transparency of the speaker. now, of course you "can" (blow the speakers) but as long as you have a good front end and you have some point of reference as to what the entire system is capable of doing, there is little cause for concern.
B&W speakers started out as studio monitors and had to duplicate the same SPL's as the source material. they had a reputation for being brutally honest, but not "delicate". BUT some people seem to be able to do things during a party that can be heard and felt a half a mile away. If you're one of those maniacs (We Salute You!) then get a no-fault warranty.

The speaker was blown when the missus unplugged all the RCA's and then replugged from the source direct to the pwr amp on one channel. I may have over stated how much a "flog them" as for too old, I'm 25 yrs old.
I don't crank them to a commercial listening level in a massive environment. My room is approx 2.4m high 7m long & 5m wide with hard surfaced furniture.
I like to get them to that level where the speakers sound full, bass is kind of empty until they get around 200-250 RMS behind them. about 75% bass driver excursion. "my amps are on the light side" 400RMS
when i blew them it hammered them so hard the tweeter went open circuit and the adhesive on the bass driver core had let go so the driver sunk 10mm back into the cabinet compared to the speaker that didn't clip.
I appreciate all of your input by the way, it is very handy to have access to a base of enthusiasts with a wealth of experience. in my town in Australia B&W only sells 10 pairs of 802's & 800's a year so expert know how is hard to come by.
Once again thanks. Just to confirm burn in time approx 100 hours?
P.S amps are on the list to buy. Pacifying the missus is like fighting a minotaur when it comes to rationalizing 30K wirth of electrocompaniet amps. BTW thoughts on Electro brand and pairing to B&W?
Thanks - Scott
