Any advantage with MDF is offset by the fact that as the box ages , you start having issues with the meterial itself reacting to the elements - when it is new , MDF is litterally perfect -edges -corners etc - the veneer bonds on with perfection - -the labour required to make a perfect MDF veneered cab takes less man hours to produce versus the plywood veneered version - - humidity on the other hand can play havoc with MDF as it deforms it - plywood cabinets will always have the advantage of being made from several plys instead of fibreboard -

these speakers will be gone in a heartbeat - simply building birch cabinets alone can cost a bundle - then adding 2 woofers -2 mids and horns - 2 tweeters -2 crossovers - yep not cheap at all -

- indeed the Atlas sound PD-5VH Klipsch outsourced midrange driver - and the Phillipines made K77 F tweeter for the Lascala II - both diaphragms are constructed of cloth-based phenolic - my error - my mind was wondering at the same time with a cornwall III upgrade that I was doing -

Since you are having a fan issue -dont forget to look for the direction of the airflow to find the correct unit - the airflow direction is usually indicated on the fan itself - -until you get the replacement - first takeout your fan - remove the paper gasket over the bearing and lubricate the bearing with oil - sewing machine oil or even better synthetic oil used for power tools - - if the fan quiets down - great - that means that the fan was on the way out - -I would call Behringer to see if they have a 24 volts replacement or if your part is under warranty - noisy fans means a worn out bearing section or motor assembly - maybe they were having some quality issues with their OEM supplier -getting a factory replacement that was tested is important - Digikey - NMB - are OEM manufacturers - - I have a lot of good luck with BGW replacement amplifier fans , as long as the airflow is the same - BGW X2500 amplifier fans units are front to rear airflow to cool heatsinks - the bonus is that they last for ever as they are truly very well designed -- take care

Decorator series Cornwalls are super -looking - they have this eternal look that will never pass - if you see the current Cornscala fad - it is just that in a more modern version of a Decorator - the cabinet is the same size overall - - being from the seventies - and if they are mint - their sound is unique so - no I would not touch them at all - if the drivers are working correctly - you have the exact same drivers than a K-HORN so it cant be made any better , this sound is unique - for us purists a rare find - Crossovers are very cheap to upgrade - -50$ with Bob Crites SoniCaps will bring back the specifications of the Crossover , SoniCaps are also a more modern Capacitor so the sound will be clearer that seventies gear were -40 years of evolution in capacitor technology - - all you have to do is unsolder and solder 4 wires - 2 capacitors per speaker crossover - or again if you can find NOS capacitors , that could be even cheaper as long as the ESR readings are low - -some capacitors when they get older have higher ESR readings , and that throws off the specs of the crossover - however if the ESR readings are ok -there is no need to change any original component - - some GE cans are still out here , a recent restoration of 4 NOS caps cost 12$ - I really like the sound that is generated from the GE cans - a perfect fit for older out of specs oil cans - - take your time and listen to the speaker - with recordings that you like -the decorators and the newer Heritage series are phenomenal speakers made to last a lifetime - take care

Hy Mike - since you have 3 amplifiers - 1) I would suggest that you try hooking the kLIPSCH CORNWALLS to the 2 other amplifiers - and test to see if the BUZZ is still there - the Cornwalls dont need a lot of power - 2) swap the speakers wiring as well in order to check the Cornwall's with regular speaker wire and the Huge monster cables you have feeding in the AVR - Klipsch ran regular speaker wire for years in the Heritage series with no issues at all - so any speaker wire will do for the testing - 3) do not over test with the BUZZZZZ to avoid possible damage to the Cornwall speakers - 4) if you can listen carefully - try to determine from where the BUZZZZZ is coming from - WOOFER -MID -OR TWEETER - regards -

if I were you , with a new pair of Cornwall III - I would call klipsch and ask them the question - take your time - the guys will most definitely help you - but you have to ask them - maybe you can send an email to Trey Cannon on this forum - as he is part of the factory - good luck -

nope - gone - the kids tossed it out - too late when I got there - they worked hard and found a woofer on ebay - I wouldn't have know if it wansn't for the missing grill -

I am searching for a single Heresy 1 grill with logo - black with copper logo if possible - after an accident , a rocking chair went through the grill and woofer - - the woofer has been replaced - I am missing a grill to restore the pair -

yes , still interested in these boxes

this thread sounds a bit like shakespeare - to be or not to be -that is the question -

now that is the best answer I ever heard - there is no subtitute for experience -

the lascala design is OK the way it was designed - you forget the experience that Klipsch had undertaken while designing the lascala speaker -and even more considering the industrial lascala setup - -the factory had divised a setup where one could add a second lower bass bin - or even a second tweeter mid section on top - you could go as high as you wanted as long as the bass bins were at the bottom stacked and the same for the mid-tweeter sections - -the separate crossover section for the LF and HF used in the lascala II - is the other improvement ala KHORN - -the first error of your design is to mess with the tweeter position - as the sound dispersion will be off - you will be searching for the sound caracteristics like a mad man - -the new lascala II have a seperate components bass bin and mid-tweeter section design - even Volti designs had a lascala section reversed ala Khorn which according to the creater was very good sounding - - you design is very interesting in the choice of higher quality components - but in order to properly create a superior sounding speaker versus the original Paul Klipsch Lascala design - you would need an anechoic chamber to measure what you are really achieving as an improvement if any - -purchasing the newer klipsch made components - crossovers -midrange-tweeter is a sure way to realise your goals - These alone will make you not want to modify the current lascala setup for years to come - and the whole improvements were tested in an anachoic chamber - this factor alone is how sound engineers work today - you can spend a lot of money and be back at square 1 - we have all tried but only a few have succeeded in creating a better lascala speaker since investing in an anachoic chamber is prohibitive- microphones alone can cost 50k - good luck with your project -please send us pics of your creations - as we are all drooling to see more - take care

the original round K77 are a much better sounding tweeter than the later K77M or F to my own humble opinion - they do not screech as much as the newer K77 square as these do hit higher levels - sometimes a less efficient tweeter can be that much more pleasant to the ear - -the newer gear is definitely more powerful , dont let anyone tell you otherwise - once you will have 2 exact pairs - you will be able to judge the difference on your own - take care

I dont know much about your HK amplifier - it looks like it is a very well built on the inside - but if the amp is bad , it may damage your speakers , from what you are indicating - this hum is like very high feedback going straight into the woofer -midrange and tweeter magnets and rezonating as a hum - 1) -check your wiring as a first step - from the amplifier to the speakers , are you properly connected in the positive and negative terminals -go through the basics of the hookup to make sure that you are wired correctly - I would also check for grounds - if ok go to step no 2- -2) check your crossovers in the Cornwall - any loose or unsoldered wires -this a long shot as crossovers rarely can create such an issue -but check them anyway - if ok then - the amp is next - -3)the amplifier looks too high tech to be the issue - but unless a technician gets a look at it - you will not know - do a google search for similar problems - 4) I would call HK ASAP and ask if they have heard of similar problems - they usually log into their databases - lookup the different issues - so they definitely can be of help here - by the way -that amp looks like a gem on the inside - what a beauty - take care - -by putting the amp away - the feedback is reduced - that is normal - similar to some turntables being close to amps or speakers - I would avoid using the amplifier before getting it checked if the wiring and hookup is ok - blown diaphragms can be your next problems - so be careful- -

I would most definitely wait to have an exact pair - and verify which crossover you have for your HERESY I - E or E2 - the round k77 uses an alnico magnet - the square k77 uses a ceramic magnet - the round K77 reaches I believe 14-15khz - the square up to 17khz - -either one will give you great sound -but only a pair will result in a balanced sound - if you can post pictures of the tweeters with a DCR reading - we can give you even more details as to what you have in your hands -

I need to refinish the scala cabs - that's not cheap - but the internals are in mint condition - I have cornwalls and I love the sound - especially playing 70 's sound - building a pristine pair of cornwalls cabs is hey not a bad alternative - and I can always take my time to fix my scalas - a few screws and they can be retrofitted - I am not scrapping my scala cabs - in any case - tx

Gentlemen- I am looking for drwings to make a cornwall type cabinet - I have 3 old scalas that I can use as donor units - I would appreciate any help from a forum member - most obliged -

Sir - are the cabinets sold - if they are , what a great and beautiful pair -- do you have the drawings of the cabinets - I would love to make 2 cabinets - I have old scalas that could be donor units - most obliged -

I am doing a follow up on this thread in regards to K28 woofers in Heresy and Heresy II - Klipsch's own Trey Cannon had mentionned that the K28 also worked well in a Heresy II - - after 2 years , can you please give us an update on how the k28 is behaving - thank you

I would take the chance - if they were well packed - but you made them and they are super looking cabs - take care -

if they are still available , I'll take them - PM sent - tx

I wanted to thank HudsonValleyNoah , for giving us such a cool essay on the K52H, K53, K-57, K-61 and K-55 motors - thank you for taking the time to answer our questions - regards

very interesting do you have pictures of these black formica scalas -were there any vibrations from the added formica tx
