Dolby DSR1260 – 12-Inch Two-Way Side Surround Speaker

What is the Dolby DSR1260?

The Dolby DSR1260 is a high-powered, 12-inch two-way passive surround loudspeaker for medium and large cinema auditoriums. It belongs to Dolby's DSR immersive surround series and is typically used for side surrounds. Its patented asymmetrical waveguide covers 60° at the top and 120° at the bottom horizontally, with 60° vertical, for linear, targeted volume across the seating area.

How does the Dolby DSR1260 work?

Immersive formats place more of the story in the surround channels, so surround speakers need full bandwidth and even coverage. The DSR1260 pairs a custom high-sensitivity 12-inch low-frequency driver with a low-distortion 44.4 mm high-frequency driver on a baffle-mounted asymmetrical waveguide. The narrow top of the pattern throws to distant seats while the wide bottom covers seats close to the wall, keeping level consistent across rows.

The speaker can be mounted vertically or horizontally so it stays out of the projector light path, and the high-frequency horn rotates within the enclosure to keep the best coverage on the most seats. A passive crossover and top-of-cabinet input plate with a high-current terminal make it plug-and-play from one amplifier channel. It is rated at 525 W @ 64.8 Vrms into 8 ohms, with 127 dB continuous half-space SPL at one metre.

Processing typically comes from a Dolby CP950A, with amplification from a Dolby Multichannel Amplifier such as the DMA32301. For overhead positions Dolby offers the companion DSR1280 with a wider 80°/130° pattern.

What are the key features of the Dolby DSR1260?

• Asymmetrical waveguide — 60° top / 120° bottom horizontal coverage delivers linear, targeted volume to every row.
• Rotatable HF horn — the horn rotates in the enclosure so the cabinet can mount vertically or horizontally.
• 12-inch high-sensitivity woofer — a custom driver supports full-bandwidth surround reproduction down to 55 Hz.
• Low-distortion HF driver — a 44.4 mm polyimide dome driver gives smooth high-frequency detail.
• Passive crossover — plug-and-play performance from a single amplifier channel.
• Low-reflection Dolby design — the enclosure finish minimizes reflection of projection light.

Where is the Dolby DSR1260 typically used?

Frequently Asked Questions

Is the DSR1260 suited to Dolby Atmos rooms?

Yes. Dolby designed the DSR series for immersive content, and the DSR1260 is typically used for side surrounds in Dolby Atmos rooms driven by processors such as the CP950A or CP950.

What is the difference between the DSR1260 and DSR1280?

They share drivers, enclosure and power ratings. The DSR1260 has a 60°/120° horizontal and 60° vertical waveguide for side surrounds, while the DSR1280 has an 80°/130° horizontal and 80° vertical waveguide for overheads.

Can it be mounted horizontally?

Yes. The cabinet can be mounted vertically or horizontally, and the high-frequency horn rotates to maintain coverage. Dolby lists an M10 safety eyebolt (#6009242) as a separate accessory.

What amplifier channel does it need?

One channel per speaker into 8 ohms, rated at 525 W @ 64.8 Vrms with a 420 W measured power draw.
