JBL L26 - 3-way

Hello Mr Gravesen,
Last November I finally finished the crossover that you designed for the JBL L26 3-Way.  It took me just shy of 3 years to finally get the job done but at last I did!!!!!!   
I cannot tell you how happy I am with the final product.  Now my speakers sound FANTASTIC.  I love them.  
I started off with a pair of L36 speakers, so I didn't have to fabricate a cabinet, I am not that handy.  I also left the cabinet ported.  
When I first go the L36's I did not ever turn them up loud because they were so forward and aggressive, they were unpleasant on so many levels.  After I got your crossovers installed the speakers sounded so good I finally stretched their feet out.  I cranked the music a bit!!  Everything sounded very good.  That is until I drover a voice coil rub into one of the woofers.  The previous owner had refoamed the woofers and did not do a good job.  I found a man in my home town that happened to know incredible amounts of information about JBL drivers.  He told me to bring them in for an inspection.  When he looked at them he said that the foams weren't correct for that driver.  It was much too stiff and did not have the appropriate roll on it.  He suggested a recone on both woofers.  I aggreed.  His turnaround time was fast and within a week I had the drivers back in for another listen.  What a difference.  I was astonished at how much better the woofers performed.  Astonished.  After a few weeks of break in and listening I may like these speakers as well as any I've owned.  
I thank you for your hard work with developing these crossovers.  What a pleasure you have brought to my L36's
I wish you a fine rest of your weekend,
Dan Trefz
