Celestion PulseXL 10.20

10" steel-chassis bass guitar speaker. Great by itself and even better in a 4×10, the PULSE XL 10.20 provides more bass than you’d ever imagine from a 10" speaker, along with the speed of response that makes small diameter drivers so popular with bass players that want to cut through the mix. A fabric dust dome contributes to a particularly articulate treble response.
