The Hsu Research CCB-8 speaker.

It's not all that small: The CCB-8 measures 15x10x12 inches and weighs a hefty 22 pounds. I didn't find the speaker's yellow driver all that attractive so I popped on the magnetically attached perforated metal grilles. The CCB-8's rear end has two bass ports and sturdy metal speaker wire connectors that accept banana plugs, bare wires, or wires fitted with spades or pins. As shipped the ports have "bung" plugs in place that seal the ports, but I used the speakers with the plugs removed. Room acoustics vary -- I recommend listening with and without the bungs and decide which sounds better for yourself. Before I forget to mention it, nominal impedance is rated at 6 ohms, and minimum impedance is 4 ohms. Hsu's warranty runs seven years, two years longer than what you get from most speaker companies nowadays.
