	So........what we're going to do is building a separate 
	speaker cab specifically for breaking in speakers.  
	I think that we'll throw the new speakers in and keep 
	a load on them for X amount of time.  
	I have since heard that if you break in the reissue Jensens, 
	that they'll sound identical to the old Jensens we all know
 	and love in our old vintage Fenders and such.
	Has anyone else here experienced what I'm talking about?
   	If so..........I'd love to hear your input.

I made a cabinet with 4 x 10" 8ohm speakers wired series and parallel
to get back to 8 ohms. The speakers are all identical and new and don't 
give the response I'd hoped. They are rated 450W each (should be enough ;),
What's the best way to "break them in"? 
What frequency (-ies), constant or varying? 
What wattage and How long ?
(I do have neighbours, and a short-fused wife, bless her!)

Thanks for any advice, Geoff Atkins
