That's for sure they ruled the motion picture sound for half a century.Unfortunately they didn't know how to run a business.Because in my opinion they made the best.Western Electric invented most of the drivers,Altec Lansing perfected them,and Jbl's are just copies of Altec's but Altec management sucked,if they were any good I would still be buying Altec Gear and not on eBay. Robert did you get those plans I posted on the model 19 cabinet plans.Regards ~ AB
