spl and sq system

what does spl mean michael12

sound pressure level, really loud systems are spl systems

SPL stands for Sound Pressure Level. It's usually measured in decibles (db's). When someone says they have an "Spl setup" it means that their equipment is just geared toward being really loud or producing high sound pressure levels. The Alpine Type R is a great sub (one of my favorites in that price range). It produces very good sound quality and still gets pretty damn loud when put in the correct box and is paired with a well matched amp. If you choose to upgrade to a Type R, I would definitely suggest also upgrading to a higher quality amp, and either building a custom box to Alpine's specs or having one made at a local shop.
