Klipsch Cornwall IV

Don Sachs,
How does the modded Cornwall now compare to the Miflex capped Spatial X5 you have?   Wait till you do more!!!!!

Yes to mods!!!!!!!!!!!!!!!!!

Other things besides changing caps and resistors that can be done that will transform the speaker:

1. Change all coils in the mids and highs to large gauge air core coils......foil sounds best. Go into the inside of the coil and out the outside for best sound. Klipsch uses all iron core coils.....not good.

2. Get rid of all connections. Hardwire the wires from the xover to the tabs on the mid and high drivers and hardwire directly to the voice coil wire on the woof. Do my binding post bypass system on the input of the speaker...see http://tweakaudio.com/EVS-2/EVS_1200_amplifier.html for large pic. Do not use the stock speaker terminal jumpers.....bi wire for best sound or use cryoed OFC wire for jumper. You always want your speaker wire to go directly to the mid high terminal for most transparent sound.

3. Damp the midrange and tweeter horns. There is a video online of someone doing this and the sonic benefits.

For those wild types.....how about time aligning.....Remove the mid and tweeter horn from the speaker.....turn the speaker upside down so the woofer is on the top and stack the mid and tweeter horns on top of the box and line up the voice coils of all three drivers.....use felt to keep the tweeter output from bouncing off the mids. The crossover was designed for non time aligning so it may have to be tweaked......this would be a big boy mod. Many of the big horn speakers time align their drivers.

Of course, there are speaker box beefing mods, adding Ground Enhancers directly to the speaker ground terminals....etc. etc. to infinity.

The most simple mod is to make sure you connect your speaker wire to the mid high terminal and make or get a serious jumper to go to the woofer terminal. The stock jumpers are crap.  Bi-wiring would be even better.  Just use some cheaper thick wire for the bass as a starter....will blow your mind.

If you stack them so the top speaker is upside down then the tweeters will be close to each other and less comb effects.....a D’appolito, if you will.  You could put some thick felt between the tweeters and that will eliminate some of the interaction between the two.
