New ASS scoops. was created by tony.a.s.s.
Today's been a good day. We completed the first of the new size scoop, which, unlike the S118 and the RX18, has a deep chamber. Tomorrow, we complete the upper bass cab to go with it. These cabs are deeper than existing models, so I'm looking forward to seeing what difference everything has made. The upper bass cab has the same footprint as the scoop, so the horn, which is folded, is a reasonable length.
I know there's not so much going on here regarding scoops, but, regarding shallow and large chambers, does anyone have an opinion as to how deep a deep chamber should be. I'm just interested in other peoples' view points.

Peace and goodwill to all speaker builders

usually the general rule of thumb is larger the chamber deeper the bass. But from what I understand about horns is that the back pressure must equal the front pressure in order for the horn to work properly. If you are familiar with Bill Fitzmaurice's Tuba 36 and Titan 48 the rear chambers are completely different. According to his spl charts the Tuba is better in the 40hz and lower range than the Titan do to the larger rear chamber. I guess you can make rear chambers larger to get lower bass but at some point the box justs gets to big for use or portablilty.
