A speaker physics question.

Ok just to be on the same wavelength, by flat response do you mean that all the frequency's are coming out at the same volume or decibel? I understand the phase part...I think.

One pure sound a fraction of a second after the next

Sum of two waves slightly out of phase

Essentially with out of phase issues some frequencies will add, others will cancel. The result is exaggerated peaks and dips. This is why the enclosure can not exhibit smooth response over a wide band.

I'm gonna work on a drawing of an infinite baffle design, I'll post it up when I get it done, what I really want to do is get rid of the boxy sound that seems to be so common in enclosures.And have a nice clear open sound...only with thundering bass. :/

Edit, Sorry I meant Open Baffle.

I beleive the only real way to do that is with an infinite baffle....... driver mounted in wall/ceiling/floor/etc.

Abe did it and he says their wonderful sounding. Check out this link.

Maybe our definitions of thundering bass are different? Certainly an open baffle is possible, but bass response is their downfall.

I think that thread got messed up in a transfer when the forum changed. The first post or so seems to be gone.

I hope no other threads/posts got messed up or deleted when the forum changed--I really consider the info/history here to be invaluable and some of it is irreplaceable. Anyone else notice any discrepancies/deletions?

Sorry Buddy, I was thinking you were saying in general they won't sound good, Yes I understand the thunder will be down quite a bit from where they are now. But I do wish to get rid of that boxy sound. I don't know if the link I posted is messed up or not but it does still have a lot of good info in it and apparently a lot of others say that after putting the 604's in OB designs they were very pleased with the results.
