Porting the woofer chamber: Back when I was at Universal Studios, they had "Sensurround" Subwoofers with 18" woofers made by Cerwin Vega. We "found" these "W" bass-horn boxes under the stage at the Hitchcock Theater. I tested and found they were really 60hz boxes unless you extended the mouth about 9 feet!...as they did have extensions to do that. But their sealed woofer chamber was 9 cubic feet. So I modeled it and added an 8~10" round port and tuned to 25 hz. Then added a LR crossover and parametric EQ and walla, I had a pretty tight 25HZ .1 channel subwoofer for film! It was not as tight as a fully horn-loaded sub, but much better than your average bass reflex box. So ya, porting the woofer chamber works well!

Almost back to abby-normal...               

People place a high value on aesthetics. 90% of the DIY efforts I’ve seen would be relegated to the garage by the Mrs.    “Garage system” and “Man Cave” is code for “not in my living room”.

I am none of those things, but sure, I dream of having some high end gear. I've also heard some $100k+ speakers, and found my MWM/La Scala mash-up sounded better.   People today don't want plywood boxes in their. The expensive cabinets/veneers won't make speakers sound better, but good looks helps sell.   Maybe it's partly because I was around musicians and recording/broadcast studios where folks were more interested in how well something worked, not how nice it looked.  

I took an 80s vintage La Scala, replaced the t-35 tweeter diaphragms and tri-amped them. I crossed over and processed with a Carvin XD-360. I time aligned and eq'd too It made a huge difference. QSC class  A/B amps were plenty of power for this incredibly efficient system. They (flown) are now the main PA speakers in our church. Interestingly I tried a JBL 2226 for the woofer and that did not work well at all. The original paper cone (Jensen?) worked much better. This new AL6/7 really changes a bunch with the (12") woofer chamber now ported and the horn going over to a tractrix with the new driver configuration. Tri-Amping is always better than the passive and leaves much more adjustability to the system. The new active system here should bring new performance to an older design!

Yes, they dig down to 45. I found setting them at 60 in my space worked very well seamlessly handing off to the sub. A bit of noodling around and they sounded together like floor standers for music. My rears are set at 80.
