Deep And Powerful Bass – Citronic CASA-15B 15" Passive Subwoofer.

The Citronic CASA-15B is a 15" passive subwoofer designed to deliver strong low-frequency reinforcement for PA systems. With a maximum SPL of 123.5dB and 500W RMS power handling, this subwoofer provides the punch and warmth needed for live music, DJ events, theatres, and corporate installations.

Constructed from 15mm MDF with a durable textured polyurea finish, the CASA-15B is built for reliability and portability. Its front-mounted steel grille protects the high-flex sub driver while side handles and a 35mm pole socket allow for easy stacking with top cabinets or standalone deployment.

Connectivity And Operation

The CASA-15B features dual rear Speakon sockets for secure amplifier connections. Users can choose between low-pass filtered output or direct input, allowing flexible integration with stereo or mono PA setups. The included phase switch helps align multiple subwoofers to avoid cancellation and maintain tight bass response.

Durable And Portable Design

Weighing just 21kg, the CASA-15B combines impressive power with portability. Side carry handles and a compact cabinet design make it simple to transport between gigs or events, while the robust MDF construction ensures long-term durability for professional audio use.
