One nice thing about this approach is the smaller capacitor that is used to keep the lows out of the midrange (as opposed to a lower crossover frequency). The smaller cap will be more transparent.
Using a 15 inch woofer to do mid range
I have noticed that Tyler Acoustics are using a 15 inch to do midrange down on their Pro- Dynamics speakers PD30 & PD 15. Isn't this pushing the 15 inch to far?
