Subwoofer ALPINE SWT-12S4 Bass Reflex 30cm 4Ohm 1000W

Alpine is the only company out there with a Stream Lined round 12inch Base Tube. It is the only 12" enclosure that will fit under the Bow Of My 1979 Ski Nautique Barefoot Boat. I only have 13" of Width, and only 28" in length, this tube is 12" in circumference (12"Round) and 26" in Length.....it is the only item that will Squeeze under the Bow....of my Boat, as far as the enclosures quality looks Good, although if a High Quality dual voice coil 2 ohm 12" Driver replacement is installed, The enclosure might eventually fail, But the 4ohm Alpine 12" driver the enclosure comes with will not damaged the enclosure. I am going to run it at 400 watts RMS, with a Primo Massive Audio Mono Block P2000.1 Alpine suggests 300 Watts RMS, Maxing out at 400 watts RMS. I will eventually remove the Alpine 12" driver and replace it with a Scar Audio EVL 12", Dual Voice coil, 2ohm driver, and will strengthen the Tube when the Original Alpine driver is removed, and install small pieces of Plywood glued next to the Alpine factory front tube supports, and a couple for the rear of the tube enclosure, But that is for later, I plan to run The Alpine Driver for all she is worth, until that factory Alpine driver gives up. HOW CAN YOU GO WRONG WITH THIS ENCLOSURE, USE IT TILL SHE STARTS CRACKLING, THEN REMOVE THE FACTORY DRIVER, STRENGTHEN THE INTERIOR OF THE TUBE, INSTALL A 2ohm DRIVER LATER ON. The exterior, and carpet, speaker connections, and Ported Hole all look well engineered, as far as the Chinese workmanship, and construction, only time will tell, Installing in a 1979 Ski Nautique Barefoot Boat, the Enclosure and it's Driver will not get used nearly as much as Someone's daily driver vehicle.....Hope this Helped, Nor Cal Vince.

Stor o klumpig o dåligt att basen inte skyddas av en nät annars bra .

Awesome, Little Bigger for a SUV , but performance is mind blowing

Qualità prezzo senza uguali è il top suona davvero benissimo, da aggiungere la professionalità del venditore che mi ha contattato per accertarsi che fossi a conoscenza delle reali dimensioni del prodotto spedizione celere e anche arrivato in anticipo... OTTIMO LO CONSIGLIO
