Hi,
As I was designing a new speaker, I decided to use the narrowest baffle I could use. In fact, the edges of the 7" woofers are flush with the baffle walls, without a round-over. I used the FRD Baffle Diffraction Simulator, and everything looked fine.
Then, as I was investigating more on narrow baffles, I found this:
And...
So far, I haven't found anything on the web that indicates narrow baffles are better, except for some comments regarding better imaging.
Is this correct? Are narrow baffles not recommended?

Well...
Narrow baffle and deep cabinets are prone to "boxy" sound if they're not done carefully. Depending what you mean by "narrow"
So, more specific parameters would be helpful in pointing you one way or another.

Q: In your VTL box design, why is the JX92S fitted in the wide face when it is common knowledge that the box should be as narrow as possible?
A: 'Common knowledge' and scientific fact are often very different. The narrow front face is a fashion concept supported by some very questionable marketing rational. The indisputable scientific fact is that the ideal mounting for a loudspeaker is an infinitely large flat baffle and this is the concept used for all loudspeaker analyses. A wide baffle always sounds better.(emphasis mine)

Only very briefly. Narrow baffles make the sound comparably thin EVEN IF you apply baffle loss correction due to poor wavelaunch and altering directivity throughout the format range. In addition, any diffraction problems by narrow baffles fall outside the HAAS window and are comparably much higher in level, meaning imaging is very much damaged and made un-natural.
A wide baffle moves the diffraction problems more to within the HAAS window (after mor ethan 1mS) and due to a larger distance to the edge the level of diffracted sound is lower. A wide baffle will support "wavelaunch" (remember, waves are spherical) to a much lower frequency and give better support to lower formants.
Acoustically speaking the modern narrow frotn tall tower speakers are about as bad as it gets, unless you build a linesource. (again, emphasis mine).
