OK, heres the story.
I received my tempest last week and will build a sonotube for it soon. However, I just sold my old sub and did not have anything to run the low end. So I decided to build a "temporary" sealed box for my tempest until I can get the sonotube project going(hey, I at least need something for bass). The design was 2 ft^3(yeah I know, my F3 is like 35 Hz) but I didn't want a huge box in my living room. Anyway, I was doing some testing with it last night with my stryke disc and noticed the tempest is still audible up to 800Hz(quiet though), and audible at the driver @ 1KHz. This is at my "Loud"(-30 on my receiver) listening level, still well below reference though(-16 on my receiver). Has anyone else noticed this with their tempest? I have a Yamaha receiver doing the crossover. All speakers are small and sub is on SWFR. I didn't have this problem with my previous sub(def tech prosub200TL) due to it having a 24db/octave slope. Does this mean I need an external x-over to get a sharper slope cascaded with my receiver's x-over?
Overall, I'm pretty impressed with the sub so far. Even with the small sealed box, I get louder readings down low than I did with my def tech sub.
