Can a baffle diffraction do this to an OW1

[harvardian]

Here is a waveform from my OWI . The cabinet has no edge recess and the driver is not flush.

In a worst case scenario +/- 5dB or so is possible from edge diffraction :-(

Ain´t life a b_tch!

So is it really THAT important to flush-mount tweeters on a relatively narrow baffle (7") ?

I want to make sure my Seas H537-06 tweeters sound great.

Yes, if you are talking about the suckout at 3.5k. Would be associated with a distance of about 4 1/8" or half that.

If I flush-mount my tweeter, do I need to also flush-mount my woofers?

My other question: What's causing that huge -10 dip right in the middle of the response curve?

Hi Guys,

Thanks,

Seem like I have two problems.

1) Tweeter is not flush mounted - causing 8.5KHz (1.6")
2) Baffle is 9" wide and not rounded - causing 3.5Khz

Time for new cabinets. These were hand-me-downs and already cutout for larger tweets.

BAM

It´s the tweeter response meeting the low fr. noise in the room.
