I like the suggestion.
Under "Other Speakers" he has the CAOW1's which -"were designed by Dennis Murphy. They are essentially the same speaker as our SongSurround I’s, but the crossover features 2nd order slopes for an extremely smooth transition between the drivers."
I have also provided a traditional fourth order Linkwitz-Riley that may prove more suitable if the speaker is used as part of a home theater system, perhaps with larger satellites (such as the 1801) that use fourth order slopes. In any event, the difference in sound is not great. But I do prefer the second order version.So, perhaps a better "SongSonnet" would be a 2nd order version of the Surround I? (CAOW1 in a Surround cab). I guess I would just like to see a dedicated mini-monitor in the Song series.
The more gentle slopes require the woofer to be surface mounted, with the upper edge of the frame overlapping the bottom of the flush mounted tweeter.
Hi Dennis,So, the 2nd order xover requires that the drivers be closer? Is that to prevent more driver interaction? Does the 4th order xover require different driver positions or simply allow it?
Hey Dennis, how bout an updated puppy picture. Your dog must be growing fast.
It's much harder to get the phase tracking lined up with 2nd order slopes, because there's more overlap between the drivers in terms of frequency response. And it's close to impossible if both drivers are flush mounted, because the acoustic center of the woofer will be much further back than the acoustic center of the tweeter--the woofer's voice coil is further back.
The vertical spacing isn't critical for a second order slope. But with the woofer surface mounted, it's possible to get the two drivers closer together, and that's always a good idea. It's much harder to get the phase tracking lined up with 2nd order slopes, because there's more overlap between the drivers in terms of frequency response. And it's close to impossible if both drivers are flush mounted, because the acoustic center of the woofer will be much further back than the acoustic center of the tweeter--the woofer's voice coil is further back. Surface mounting the woofer brings the acoustic centers closer in line and reduces the amount of electrical delay you have to build into the tweeter circuit. The alternative solution is to use a sloped from panel, but that raises costs and introduces some other problems. Is that snoring I hear out there?
