  1.  

     

    I cannot think of a single two or three way based upon a single eighteen inch woofer

     

    EV had the Patrician iV  using the  EV 18WK  in a corner Horn.  http://electrovoice.com/downloadfile.php?f=Patrician%20IV%20DIY%20Manual.pdf

    The Patrician iV was essentially a licensed 18 inch KLIPSCH khorn , and pretty rare to boot -   the 18 inch woofer added bass accuracy in larger rooms  -  in this case , larger is better while remaining efficient -

  2. they look just like a pair I own ,  I am not sure if you noticed but the speakers are very close to the floor and the aluminium trim will oxide as a result of being  close to a humid floor - a clear coat will not stop any oxidation as the surface underneath is not coated - 

     

    -for your info -most of these split Lascala pro speakers were not coated with a truck bedliner paint on the birch plywood veneered wood but rather fiberglassed at the factory  for commercial applications -

     

    are the pocket handles  KLIPSCH originals - small detail - otherwise - cool cabs -

  3. -the removal of the MP3 player cable damaged the diaphragms on the horns ,

     

     

    -you mention that the power was up , so my guess is that when you removed the cable , the music program stopped as well and the amp was on full power resulting in a surge in power to the horns  - that surge in power is sufficient to zap the horns for sure , the crossovers at this point delivered a power transient that was way off the power handling capabilities of the horns frying the voice coil of the horns -

     

    -you will have to open the horns and inspect the diaphragm for signs of damage - take a screwdriver - remove the screws - remove the wiring connectors -unscrew the screws holding the horn to the driver -remove the diaphragm - check for a smell of burned plastic - look at the voice coil windings for apparent damage -

  4. The HIP were made in 2 versions  = the tweeter had  the K77M square magnet - the mids -the K55V or K55M - in the woofer - there is the EVM12L musical instrument or the K42 from Eminence -

     

    -the KP 250 was an evolution of the HIP with twin ports at top instead of the lower one on the HIP -I prefer the HIP versus the KP250 - as the EVM12L , the K55V-M and the K77M combination is unbeatable and extremely  expensive high quality components -

     

    -these are a ported Heresy cabinet  versus all the home Heresy cabinets that are all non-ported - you are giving up bass but adding a lot more power handling -

     

    -the crossovers look like an AA for the scala with Zener diode tweeter protection for the precious K77M - updating the crossover to the late specs capacitors will give you an even better sound than the old caps ever did - as a matter of fact , the ESR readings of the old caps were way off even when new -

     

    -so for a win win situation- just ;like Mr Morey James said it earlier - upgrade the caps and enjoy the truly well built HIP -

  5. tx for the info - but are these available in 4 ohms as well or only 8 ohms -

    BD15: top notch quality, deep bass in right Q box, reference upper bass, high efficiency, fast and devastatingly linear!

    I preferred it over CW1526©: absolutely

     

    Beyma 15LX60V2: deep bass, high efficiency, fast, pretty linear

    I preferred it over CW1526©: Yes

     

    Faital Pro 15PR-400: deep bass with good punch, highly efficient, build quality is superb. looks humble

    I preferred it over CW1526©: Yes

  6. point well taken  , my goal was to build a cornscala with CP-1 front dimensions with the depth of a Cornwall 1

     

     

    -I have a pair of CP-1 that are using an EV18 inch woofer with no issues for several years  - the motorboard was cut for the 18 inch fit -these are not driven hard and are way better at delivering bass than a 15 inch  CP-1 K44E - the time alignment of the woofer -mid and tweeter is fantastic to say the least - with no mods to the crossover as well -

     

    -bass is tight - mids are very detailed and the tweeters with Crites titanium diaphragms are very smooth - you can feel the punch in your chest and all the sound is there with great presence -

     

    -a hybrid of the CP-1 and Cornwall 1 is what I want to build and should be even better balanced - it would result in a slightly bigger bass reflex enclosure and  could handle more power as well - TX

  7. Happy 2015 to all the forum members  -my question is something I have been thinking of for a while - basically installing an Eminence -EV-JBL 18 inch woofer in a Cornwall -cornscala cabinet - the idea here would be to improve the low end sound - 

     

    - I am wondering if that trial has already been done with sucess by another forum member -  the issue here is the fact that cutting the motherboard is irreversible once done -

  8. no wonder these did not suit your needs - you should have gone with k28 woofer of the Heresy III - 4 ohms - these really rock -klipsch parts sell the kit complete - woofer - mid driver-tweeter -crossover - now that is really nice sound - balanced - good luck
