Norm Cerveny is a custom speaker designer whose designs have won several national competitions, your ears will tell you why his crossovers are so acclaimed. Never had a problem with bleed thru even when I experimented with closing the ports all together the k-52 really pushes hard. Enclosure will be 3/4" smaller, haven't gotten to the tuning yet but we are getting close still working on the cabinet. Definitely will post when tuning is complete.

Came across a set of 30's for the right price so I decided to attempt a ground up re- design in an attempt to finally squeeze from this speaker the bass it SHOULD be producing. Although I currently own a pair of KLF 20's and a pair of KLF 30's, I couldn't pass these up at the price point I STOLE them at. Planning to reinforce the cabinet to the tune of 1.5" mdf ( box-in-box) with all the proper dampening, insulation, bracing, etc. Cabinet re-tune, correct those useless ports, and in all likelihood will try a non-crites crossover custom built by Norman Cerveny Pro Audio. Will refinish the outer cabinet as well with unfinished wood veneer with many coats of Hi Gloss lacquer, haven't decided on a stain color yet. Although KLF 30 mods are fairly standard these days, Norm Cerveny will be doing these from start to finish since this will be more than a simple modification.

Reinforce, how? Do you mean building a box-in-a-box? If you are wanting to do a stringer, I might suggest using a hardwood. MDF is really just sawdust and not a good material for a making a strengthening spine. Box in a box with bracing. Gonna apply new veneer as well with a couple of coats of lacquer.

Need a single K-52 driver and horn for KLF-30 rebuild. Came across a set of 30's for the right price so I decided to attempt a ground up re- design in an attempt to finally squeeze from this speaker the bass it SHOULD be producing. Although I currently own a pair of KLF 20's and a pair of KLF 30's (love these monsters) I would rather not pull a driver from either for this rebuild.

Will refinish the outer cabinet as well. Anyway one of these new old 30's as purchased contained a Selenium mid driver attached to a cracked horn. Certainly not complaining with regards to the Selenium squawker but I have a set of Ti's I would like use. Will trade the Selenium if necessary. Although a KLF 30 rebuild is fairly standard these days I am fairly anxious haven't done one in years.
