Great little woofer
I built a pair of small bookshelf speakers with these woofers mated with HiVi's T20-8 tweeter, using the recommend sealed enclosure size. I crossed them over at 5Khz, 12db/octave. The speakers came out great, vocals (and everything) sound very natural and lifelike. these woofers sound clean and tight.
