Linkwitz W-Frame OB woofer design question:
- Am I correct in understanding that in this design the two woofer voice coils are closer to each other than any other configuration, and the overall distance of the woofer voice coils from that of the mid/tweeter is low because of the low profile? This enables the woofer to be crosses much higher in comparison and also makes for a better point source in a multi-way configuration?
- How high can such a design go? Eg: can 3 inch mids also be productively used in this configuration?
- If the polarity is reversed, the "FRONT" and "BACK" will swap places and it now operates similar to Nelson Pass's slot loaded woofer. Which of these configurations is preferable?
- What are the disadvantages of this design in comparison to other OB designs like the H-frame or U-frame or the I-frame flat baffle?
- What are the the general design guidelines/rules of thumbs for such designs? I understand the quarter wavelength rule but I'm also interested in the area of cross-section, volume, depth width etc. of the front and rear slots
