660R Double 18″ Vented Sub – Permanent Install Version

Category:

Description

This vented double 18” sub woofer was designed with an emphasis on low height to fit under platforms and stages. The 660R uses two upgraded 18” woofers with 4.5” voice coils. Very tight & punchy with a good combination of low-end frequency range qualities. It is similar in response to the tour version, but has no need for transport hardware.
