Thanks for the links john. Looks like the consensus is that adding stuffing to a ported enclosure lowers frequency extension but decreases efficiency. Judging from other people's experience, I think I'm going to try lining the walls with foam and just listen for the effects. Thanks for...
bryan, the dust cap is carbon fiber. Thomas, what type of acoustic foam worked best? Any links? I am seeing different types of densities and thicknesses and not sure which one to use. Also, what types of improvements can I expect from using acoustic foam?
Started my own thread, felt bad hijacking kurts. Any other avalanche/atlas owners feel free to post your pics here. If you don't have the means, I can host them for you. Each avalanche 15" sub is approx 150L tuned to 19hz. One has 2 18" PR's. The other has 3 15" pr's. I will probably fill...
I feel bad hijacking kurts thread... didn't mean to. I'll start my own. Geoff, I'll answer your questions in that thread. http://www.hometheaterforum.com/htfo...hreadid=223335
Hey mark... Thanks for all the info. I always learn something new here. I had chad model them out on Leap and it seems that the tuning is at 19hz. I'll try out my test tones and look for the minimal point of excursion to verify. The finish is a birch veneer with ebony stain and lacquer...
thanks jack, The box itself is a 24" cube (1.5 inch thick enclosure) so around 6.5 cubic feet internally. One sub has 2 18" passive radiators, the other has 3 15" radiators. I initially had AV15's in there but swapped them out for some avalanche 15's. They were initially tuned for 19hz, but I...
Nice to see some others using atlas/avalanche drivers. I just finished 2 avalanche 15" subs. Nice clean output. take a look Kurt, I'd like to see your sub. Send me the pictures over email and I'll host them for you. [email protected]
I have 2 15" drivers for sale. They are the TC Sounds TC2+ model. These are identical to the Stryke AV15 MK1's. I'll be honest and say these were the batch w/ the progessive spider. Stephen from TC sounds treated the spider with extra phenolic to increase lateral stability. But during the...
The subs are finally done. I was able to sand off the finish with a belt and orbital sander. There are some small spaces where I went through the veneer but are tough to see. I ended up using a pre-conditioner, then ebony stain, topped with several coats of lacquer. Overall, I'm very happy with...
