The all new Skar Audio TXL series spent over a year in R&D, but Skar is finally ready to release their most powerful and efficient subwoofers to date. The TXL series has a 3.5” copper voice coil encased in a massive motor assembly. Designed with an extremely effective cooling system, these subs are by far the most efficient speakers Skar has ever released. Just like all of their subwoofers, they kept sound quality and SPL as their main priorities when designing these monsters. The TXL series is conservatively rated at 2500 Watts RMS and is sure to get LOUD. For beginners and enthusiasts, one sub or twenty, this subwoofer line will blow the competition away.
