AudiogoN Forums: Tailoring tweeter output

Tailoring tweeter output

Many companys recommend listening with grill on, like Avalon or Dynaudio. On stereophile measurements, the grill changes direct output from the speaker significantly. I am experimenting with this, any recommendation on specific material. Does the reflected from the padding/grill sound create any issues?

THanks

Recently listening nearfield and find the ribbon tweeter too hot. trying to decrease out put from 8khz and up.

Thanks

The Ribbon tweeter has very wide dispersion so toe change will not work. The 3-5Khz region will drop before attenuation of the tweeter.

I am adverse to cable tuning to decreased 8-12khz output. Any cable that accomplish this would limits bandwidth.

I hav tried the long wall setup. It is the same with much more bass issues.

I have also moved the speakers 3' from side wall and this does not change much. The direct sound of the tweeters are measuring a little too hot, this is done by setting gating time low to minimize the side wall reflection.

Many thanks to everyone. I will update this as I try the suggested solutions in the future.

I have very rudimentary understanding of room acoustics so I have done mostly trial and error. The long wall setup resulted in a 12-15db peak at 40Hz which is insurmountable to most traps. I even plugged all the ports and treated the back and front wall.

Most of the time, less toe in should reduce high freq energy. My problem is that the midrange driver has a narrower dispersion than the ribbon tweeter.

I think the ASC is great in offering diffusion in combination with bass trapping.
