So if the box includes a passive radiator, it is technically not "sealed"? Which would make my Thiel 3.6s and Sunfire subs not acoustic suspension?
Why not acoustic suspension?
When I was young, late 60's early 70's, the sealed or acoustic suspension speakers were quite commonplace. Now bass reflex, ported speakers seem to be much more common. My understanding is that both speaker designs, assuming competent design will perform very well. Perhaps with the ported getting a slightly lower bass response and higher efficiency gives it the edge. Thinking efficiency though, amplifier watts don't cost that much more today so it doesn't seem like a deal maker. What I don't understand from a pragmatic corporate standpoint is why more acoustic suspension speakers aren't available. My understanding is that the sealed speaker box can be smaller which would be a plus from a cost standpoint, both in less material, lighter cabinet and more speakers could be shipped in a truck reducing shipping cost. Any thoughts as to why the industry has shifted so hard in the bass reflex direction?

I am concerned about insect or rodent infestation through open rear ported speakers such as the MoFi Source Point speakers. With these speakers the port is open and low enough for a rodent to climb into. I'm 73 and I remember back in the 70's many of the speakers were acoustic suspicion such as Advent and KLH. Yes, acoustic suspension speakers seem to have lost their popularity. I treasure my acoustic suspension Kirksaeter speakers.

@dynamiclinearity After this thread sparked my memory about those old speakers, which i thought, in my youth, were just white van speakers, I went googling and realized that what I actually owned were the ESS-made Cannon TLS 1030's. 😭 |
