A tweak that actually worked!

Thanks!

I would have tracked it doen eventually! But I'm glad you chimmed in!

Thanks D-MAN for being the voice of reason! I believe you hit the nail on the head!

This little thread is quite interesting for me. I told D Man last week that I'd ordered slate caps to sit atop my Khorn bass bins. The top horns will be exposed and I needed something to cover the bass bins with and sit those horns on. Well those slate caps will weigh in at over 100 lbs each. Then I've got 25 lb JBL 2482 mid-range drivers to add to the mass. In all it's probably twice the weight of the standard khorn upper section.

"I hefted the bags up on to the 2 1/5 foot wide tops of my old Klipsch horn loaded Cornerwalls. I listened for tone and contrasts by alternating the bags on and off."

Cornerwall?

I think arguably better is doing what I did. I used a couple bottles of

Gorilla Glue and attached my Khorns to the corners--walls and floor.

Unless you actually need to ever move them!

Lead shot should be sealed well enough to keep curious pets and children from getting access to it. Very toxic. Sand works fine and is cheaper and safer.

Want to add mass to the speaker? Why not do what I did? I secured my Khorns to the friggin' foundation of the house with 18 lag bolts! Now they're mechanically coupled to the mass of the Earth. Can't do much better than that. [] And yes, it did make an improvement, mostly in the middle & treble registers, not the bass range like I thought it would.

would anyone mind explaining to me how bolting a khorn down would improve anything but the bass bin? i'm not seeing how the squawker horn and tweeter could benefit from this

The reduction of cabinet vibration means the squakers and tweeters are

moving less too. And any reduction ultimately results in less frequency

modulation distortion (aka doppler distortion).

Also, the "quality" of LF information dramatically affects the

percieved midrange. Think about it....we can describe a "bass shy"

speaker as sounding "harsh." It has everything to do with how the lower

frequencies modulate the higher frequencies - cut out the low end and

you are physically changing the waveform of the upper frequencies.

you're always around to give great explanations.

thanks again.

I'm helping design a new basement HT where the front wall will

incorporate false corners for the Khorns angling the Khorns to point to

the first row sweet spot.

We are planning on mass loading the false corner section by filling the

stud spaces with sand and screwing the khorns to the false

corners. The result should be somewhat simular to Art's earth

mount.
