Superb bass for 3-way high-end designs

This one is a close cousin of my earlier favourite SB29NRX75-6. This has a slightly higher impedance, which makes for a less expensive crossover if a passive crossover is being used. But a high quality woofer like this one is best used with an active line-level crossover with equalisation in a sealed enclosure.
