My New Audio Nirvana Drivers - Page 83

we look at the response curves that show the sensitivity of the speaker (not the driver alone, but the speaker as a whole) at each frequency.

we saw that the best bass response (most sensitive) is when the cab is naked, with no acoustic padding

but that doesn't mean it will sound better without padding, because the entire cab will be resonating due to standing waves n ****.

to see how the acustic padding improves the speaker (if it does) we need you to do impulse response measurement.

OK. Yeah I can do that.

Testing a new kind of acoustic dampening material.

Do the eyes flash in time with the music?

Can you get your video camera out, set it up on a tripod, then run 10000Hz at 1 Watt, then upload the video to youtube

Just want to make sure that stuff works well

I've never had any truly flat, wide BW, power response speakers, so never gave it much thought, but if Tom says his Synergy concepts work best overall toe'd in as I suggested earlier, then the way we hear pretty much dictates it regardless of the speaker's polar response.

WRT beaming speakers 'splashing' behind the listening position, it's always a good idea for this area to be diffuse in nature, so bookcases, heavy drapes, etc. is a good plan.

Maybe brain cavitation is a better description then.

brain open baffle?

I am trying to think of something really dumb to say but that requires the operation of far to many brain cells.

I am in brain cell conservation mode.
