More info
The T252-S 5.25" is an alternative component system to the T1 with a major difference being a Billet aluminum phase plug to enhance cooling. The woofer features the same VAST surround having up to 25% increased cone area and a Flex Fit Basket for easy mounting. Another difference is the Aluminum Dome Neo-Tweeter for Fanatics who prefer this type of tonal quality over the T1. The same external audiophile crossover is used, configurable for single or bi-amp configurations.
