I tried the upper enclosed horn modification and the lower one that you are showing - both work but nothing to really brag about - it adds some bass effect -- but this aint like a Cornwall - I find it alters the quality sound out of the Original LasCala setup - - the real improvement is done by adding a subwoofer - setup - like the SW-15 series from Klipsch http://www.klipsch.com/sw-15 - http://www.klipsch.com/sw-15-ii - these subs alone bring out the low frequencies that the Lascala cannot reach - a single is sufficient - as it also carries a passive radiator - -Klipsch had another solution which was the way the original design was made to work - simply adding a second Lascala bass bin - -good luck -

I understand that your advice is to move the mids and HF up a tap, basically raising the spl by 3db and change the mid cap - to what value should I change the mid cap to - thank you

I was wonderIng what is the DCR average reading for the K42KP pro 12 nch woofer - thank you -

Neil - Thank you very much for the HERESY II grille frames - they got here in excellent condition -and I will put them to use very soon -

Gentlemen - Can anyone tell me what is the NORMAL - DCR reading of a Klipsch k42kp 12 inch woofer - thank you very much - '

check the woofer or the bass bin panel /door -

Gentlemen - I just bought a couple of k42 KP woofers - I was wondering if these can work in a Heresy I or Heresy II cab while using the original crossovers - being 8 ohm woofers alike the k22 and k24 - can one expect a better sound - more detailed tones - or is it back to square one - the k42 kp can handle more power so can I expect to being able to have the speakers go louder before the woofer reaches the distortion levels - -finally - is the original HIP crossover that uses the EVM12L Compatible with a K42kp - I understand that this is very similar to the AA netword - tx - your input would be appreciated - very much obliged -randy -

I would definitely need these - pm sent - tx

thank you Mr Crites for showing the pictures of the 2 - - -I had 3 of these OEM diaphragms made by EV - with the copper-beryllium flat leads - I recently installed them - no comparison at all with the k77F or aftermarket diaphragms - they have this consistent tone reproduction of sound in the high frequencies - even at low power - this type of copper -alloy is also very highly conductive - -the aftermarket and K77F tweeters on the other hand are less clear in sound reproduction - one needs to raise the power to hear the detail of the melodies - hence , as they are always pushed to their limits - they will fail prematurely -

let's bump it

love the bump

lets bump it again bump

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 -
