Perlisten R4s THX Ultra Surround Speaker

The R4s angled on-wall surround is the final piece to any great system with the same R-series DPC array to offer real timbre matching on every part of your Perlisten Home Theater. We take Timbre matching to another level and no sacrifices are made just because it’s a surround, we care, and know you do too. Not only are the same materials used but the same response targets for on and off axis response that the R-series and S-series speakers uphold are used because you deserve it. Flush mount on wall bracket is included and optional tilt and swivel bracket is available.

As with all Perlisten loudspeakers, the R4s is centred around the DPC array (read more here), comprising of three 26mm soft domes in a vertical array. The centre dome is the HF unit, covering frequencies above 4.4kHz. The output from this unit is controlled on the horizontal plane to reduce dispersion to focus on the listening position, reducing HF reflection from side walls. Vertically, its output is highly controlled, vastly reducing floor and ceiling reflections.

The flanking 26mm midrange domes cover between 1.25kHz and 4.4kHz, producing a more responsive midrange that is far less coloured by what would conventionally be a larger driver.

As the R4s is primarily designed as a wall-mounted effects speaker, the DPC array sits below a 6.5" bass driver covering from 1.25kHz downwards, acting in a sealed cabinet making them very room friendly. They're flexible enough to also be used as all five loudspeakers in a wall-mounted 5.1 surround system, for example, for those wanting a non in-wall, but discrete high performance system.

The R4s will cover 300Hz-20kHz within only a very narrow +/-1.5dB deviation, with typical against-wall placement providing a bass response down to 48Hz at -10dB, and produce a peak output of 109.5dB.

All of this tech helps the R4s achieve a THX Ultra rating, capable of effortlessly filling large rooms with cinema levels of sound quality.
