The real overlooked sub is the Martin Logan. Sunfire subs are fine but all high power subs eventually break and repair pricing on the Sunfire's are very high. ML repairs are very reasonable having dealt with this recently. A friend recently trashed his Sunfire because it was worth less than the repair costs.
Look at the ML Grotto. Fantastic sub for the $$.
