does anyone know if jbl actually offered an upgrade on the L150's that replaced the 12"PR with another woofer ,on ebay there is a set ,this is the second set i have seen with double woofers, it is definitely not the same pair because the first set had 033's for tweeters ,this set has 044's . so i wonder if they were sets that someone just put in another woofer and wired as they saw fit ,or is there some kind of crossover upgrade also etc. or was it an upgrade that was offered at the certain dealers.
thanks
