In Reply to: RE: Tilt or raise horn system posted by kyle on March 02, 2015 at 12:14:38
I had Heresy lll on the floor pretty much on axis to the mid now up on stands directly at my ear now looking down the throat of the mid horn and I prefer it up on the stand. as always YMMV. Have done the same experiment with a number of other mid horns and I always prefer them parallel to the floor and at my ear level. Best regards Moray James.

James,
Mh problem with raising my HIIs vs tilting using Bob Crites' riser I just got a bit ago is the loss of bass. I actually like the bass output of the HIIs as I listen to classical and jazz, neither which dig deep below 50hz and have no desire to add any auxiliary woofer system. My HII had neither Klipsch riser so, Bob's made sense for me. My setup has me looking down the throat of the mid and tweeter using the riser. At your suggestion I did raise them, just put them on an idle speaker with the woofers facing away from the seating position and covered to minimize as much sympathetic effect as possible. The idle speakers are coupled room the floor and there is no isolation between it and the HII.

Here is a picture of one of my Heresy lll sets up on 21 inch Skylan four post stands. As you can see the factory riser has been removed. The stands are on Teflon glides to make for easy positioning and they also sound better than on spikes on the concrete pad that they are on. I have done numerous modifications to both the cabinet and the drivers to these Heresy lll and they make considerably more bass than a stock pair of Heresy do mounted on the floor. Best regards Moray James.

Thanks James. Is it my eyes or do the drivers on the III mount from the inside? Could just be the grill and lighting but it looks more.like tje original than what I see through the grills on my IIs.

The drivers on the H3 all mount from the front (outside the cabinet) the rear panel is fixed. You are seeing a 1/8" layer of F-11 Acoustical Felt around each of the horn mouths and over all of the woofer. Around the horns the F-11 is catching diffraction while over the woofer it is acting as an acoustical filter and as an acoustic load. I have also included a link so you can see the extensive solid white oak brace work inside the cabinets. The cabinets are internally damped with high density fiberglass ((about 90% totally stuffed) which is positioned such that only cut edges face the woofer this makes it much more absorbent, how the fiberglass is oriented when installed makes or breaks its use in this situation. There are also extensive modifications to the drivers and horns. Hope this is of interest. Best regards MOray James.
