I was showing my boss my new Tempest and in a sudden moment of sub envy he declared he wanted one! I knew this hobby was contagious! :wink: Anyway, he's just starting out and has a box almost finished (that was originally for a cabinet, but never got finished, so for simplicity's sake I'm directing him towards a sealed Tempest. The box is in between Adire's Mid-Q and Low-Q designs at about 5.7 cu. ft. (internal). Should this be a good arrangement for a DIY newcomer? The box is made from 3/4" plywood, and will be sealed with silicone, I told him no leaks. It is: H 33" x W 20" D 18" and he wants it to be front firing as well. It will be powered by an old 2 ch. amp with about 100w per/ch... I'm assuming he can just hook one chan. to each VC (the amp will be operating in mono from a split sub-out signal from his Marantz receiver). Any input here would be great considering I just ordered the parts for him this afternoon. I'm just not too clear on how a sealed box is "tuned". It's easy with a port!
