Crescendo – Evolution 7S3 Active

The 3 way speaker of choice for championship cars with budget limit. Even though, it is the winning speaker of EMMA Asia 2017 an 2018 Master Unlimited Class.
Each driver is dedicated for its working range. The woofer is pure, not mid-woofer (mid-bass). Narrower bandwidth makes it more powerful to deliver the kick bass.
