That's not necessarily true. The size of the driver and the frequency range from the driver is more important since that determines the wavelength and for high/mid frequencies the wavelength is not long enough to be affected by the (large) baffle size. Low frequencies with longer wavelength behave completely differently.
narrow and wide baffles and imaging
According to all the "professional" audio reviews that I've read over the last several years, narrow baffles are crucial to creating that so-desired pin-point imaging.
However, over the last few weeks, I've had the opportunity to audition Harbeth 40.2, Spendor Classic 100, Audio Note AN-E, and Devore O/93. None of these had deficient imaging; indeed I would go so far as to say that it was good to very good.
So, what gives? I'm forced to conclude that modern designs, 95% of which espouse the narrow baffle, are driven by aesthetic/cosmetic considerations, rather than acoustical ones, and the baffle~imaging canard is just an ex post facto justification.
I can understand the desire to build speakers that fit into small rooms, are relatively unobtrusive, and might pass the SAF test, but it seems a bit much to add on the idea that they're essentially the only ones that will do imaging correctly.

"No matter how you cut the cake, big baffles aren't good if they're anything resembling flat with corners. " That's not necessarily true. The size of the driver and the frequency range from the driver is more important since that determines the wavelength and for high/mid frequencies the wavelength is not long enough to be affected by the (large) baffle size. Low frequencies with longer wavelength behave completely differently. |
josh358 The problem that I had with the imaging of the IRS Betas that my friend had was that each frequency range came from a different height. Maybe his listening seat was too close, but it used to drive me crazy. Very cool plasma tweeters, by the way!The IRS Beta system is highly adjustable, which is a double-edge sword. On the one hand, it makes it possible to achieve excellent results in rooms with very different characteristics. On the other hand, it makes them easy to setup incorrectly, and it sounds like that's what happened with your friend's system. The Beta system used planar tweeters, not plasma. It looks like your friend's system was modified. |
melbguyone Re: the IRS-Beta’s ... I don’t think the narrow wood frame of the mid/high panels was completely adequate to tame the resonance of the dual L-Emim drivers as they would ’rattle’ at high volumes.Huh? I've never detected any rattling at all with the IRS Beta system, with the exception of when the woofers need to be re-foamed. |
