Has anyone bysides me removed the screens from there tweeters like 034, 035ti or 044ti's and noticed the big sound improvement. There is alot less smearing of the HF. I know there is a big danger of damaged , but the sound improvement is worth it to me.

I removed them and heard no difference.

The ear has a poor memory. The only way to do really this objectively would be an instantaneous A/B. (Perhaps two tweeters in the same cabinet that could be switched between instantly).

What I did was pulled the rubber rings out set the screens back in they stay in just fine. Then play a song then jump up and pull the screens out and play the same song again. If only take about 5 seconds to do a A-B test that way.

If the screens were not clogged I would think very little difference if at all!

Just my 2 cents worth!

I haven't taken the time to manually push all the wires in a screen together to see just how much solid area it creates, but I think we'd be surprised at how much solid material there is. The fact that it's a mesh means it has a different impact than a solid blank of metal placed in front of a tweeter, but I wonder what the engineering decison was that placed those screens in front instead of something else.

The decision was based on all the caved in 066 domes JBL fixed under the "goodwill gesture" clause. You have to remember, most people are retarded and have to push every "button" they see. A 1" dome resembles a button to alot of people. Some people have a real problem with that and put screens and such in front of those "buttons" to keep them from getting caved in.

That reminds me when my daughter tried shoving a peanut and jelly sandwich into my cd player. She had it in the disc tray and when I woke up she was trying to push the tray into the player!!!:baby:

I believe that why JBL used bigger screen on the 046ti and the 093it.

I am just guessing that why. Do you know why they really change to the bigger srceen?

5 seconds is about 4.9 seconds too long.;)

I've thought about it with my 035ti's, but haven't tried it yet. Not sure if the potential sonic improvement justifies the risk of dome damage.

Goofed-up cones/domes = vewy angwy JBL listener :bash:

This improves dampening of that really high sound:blink:

I thought they were there to keep out nesting bugs/spiders and the like in outdoor instalations... maybe my basement too !

In the interest of presvervation I'm willing to give up a bit of fidelity to maintain structural integrity of the tweeter domes on my 044s and 035TIs.:nanana:
