Phase Technology PL150surr On-Wall Surround Speaker / 6.5in Woofer / 1.125in Tweeter / 87dB / 4 Ohm

Description

The Phase Technology PL150surr is an on-wall surround speaker engineered to deliver clear midrange and defined bass in a compact profile. It combines a 6.5in RPF flat-piston woofer and a 1.125in synthetic soft dome tweeter to reproduce a wide portion of the audible band with low distortion. The enclosure is finished in high gloss MDF to provide a refined visual aesthetic that integrates with modern AV systems.

Key acoustic components include the 6.5in fiberglass and Kevlar composite woofer and the 1.125in soft dome tweeter which provide improved transient response and controlled dispersion. The speaker is specified at 87dB sensitivity and a 4 Ohm nominal impedance, offering reliable compatibility with most AV receivers and amplifiers. Recommended amplifier power ranges from 10W to 150W to accommodate both gentle listening and higher-output playback.

Performance is tuned for a frequency response of 80Hz – 22kHz (±3dB), delivering balanced midrange clarity and extended high-frequency detail. The sealed enclosure topology yields tight, controlled bass extension and predictable low-frequency roll-off. These attributes make the PL150surr suitable for surround channels where consistent timbre and controlled room interaction are important.

Connectivity is handled via gold-plated 5-way binding posts for secure wire termination and low-resistance contact. The 4 Ohm nominal impedance requires considering amplifier drive capability during system design to ensure full dynamic headroom. The speaker’s sensitivity and power range allow it to pair with a wide range of AV receivers, dedicated stereo amps, and multichannel processors.

Common installations include discrete home theater surround channels, multiroom music rooms, and dedicated listening spaces where on-wall mounting conserves floor space. The slim depth and elegant finish help the speaker blend into wall-mounted layouts while contributing spatial imaging to immersive mixes. Multiple units can be used to create cohesive surround arrays with matching voicing.

Build quality emphasizes long-term reliability with an MDF enclosure finished in high gloss and robust internal components. The unit ships backed by a 10-Year Limited Manufacturer’s Warranty which supports long-term installations. Installation is straightforward using standard wall-mounting hardware and the speaker’s compact footprint simplifies placement and concealment of cabling.
