Sub tuned to HZ?

[Session25 10+ year member]

Hey, I just got into car audio, and I'm trying to figure everything out. haha. Anyway what does it mean to tune a sub to something HZ? i know it's like the sound, but how do people know what's the best? I'm getting 2 12" alpine type r's, and I don't know what would be the best for them. Also what does SQ, mean. Sound Quality?

SQ- Sound quality

SPL-sound pressure level

HZ- Hertz, its a tuning frequency. Higher the tuning, geared for spl. Lower the tuning, geared for SQ.

The alpines will like 4+ cubes, tuned to 34-35.

Enclosures are tuned, not subs. It refers to the point of resonance in the enclosure. The tuning point of an enclosure is not related to the subs at all but different subs work better with different enclosure specs.

For your Type Arghs go with around 5 cubic feet net tuned to 34 hz

sound pressure level just refers to how loud the subs are in terms of dB or Decibel
