Different OB designs for woofer + FR

[Nuuk]

My point was trying to _understand_ the issues involved when designing a narrow vs wide baffle and using one vs. two woofers.

I'm with you now! Well, it is an interesting subject for sure! I'm doing other things at present but may get back to OB building later in the year.

Hi Florian. As for baffle width, wide versus narrow, I think each has its merits. Wider gives better bass response, narrow better midrange.

I am not a great fan of sims, however The Edge may give you some insight. You don't have to stick with rectangles either. I ended up with this test baffle, used to tweak drivers.

The biggest problem we face is getting deep bass from a finite baffle. What we need is a high pass acoustic filter to go behind the driver.

Adding a woofer improves the situ for a number of reasons. The W/R purists frown on the idea for valid reasons. I am of the thinking that an AP enclosure for under 150 Hz or so, is the way to go, for it's transient and phase response. The W/R unit should be unfiltered, the woofer crossed over such that it fills the hole, with minimum phase shift.

Some will frown on that. It's a compromise that this W/R OB fan can accept.

Geoff.
