Greetings all.I'm busy building a subwoofer, and I want to use the Tempest driver. Basically, I've almost finished constructing the enclosure.I want to go sealed.So I'm going to provide you with the dimensions of the enclosure that I'm going to build, and then if you would be so kind, you could tell me if its a good choice. The dimensions are : 28" H X 18" W X 32" D.I think that this is a very big subwoofer enclosure.Who do you think? Is this a good size for a single sealed Tempest subwoofer? What type of extension would I achieve in this size enclosure? Thanks. Any problems, then please let me know.
