Напольная акустика — Klipsch R-605FA

Klipsch's R-605FA, part of the Reference range, combines a two-way tower with a built-in up-firing Dolby Atmos speaker in its top. It is sold as a standalone model and also forms the front pair of Klipsch's R-605FA 5.1.4 and 7.1.4 home theater packages. Its MDF cabinet carries a black wood grain vinyl wrap. Each tower adds a Dolby Atmos height channel without a separate speaker in the ceiling.

Key specs that matter

The main section uses a 1 inch aluminum LTS tweeter with Kapton suspension in a 90 x 90 degree square Tractrix horn, crossing at 1,440 Hz to two 6.5 inch spun-copper TCP woofers. It is rated at 38 Hz to 21 kHz within 3 dB, 96 dB in-room sensitivity, 100 W continuous and 400 W peak, and an 8 ohm compatible nominal impedance. The height module has its own 1 inch aluminum LTS tweeter on a matching Tractrix horn plus a 5.25 inch spun-copper IMG woofer in an acoustic suspension enclosure, handles 75 W continuous and 150 W peak, and is specified to conform to Dolby Atmos requirements for response and sensitivity. The tower is 1017 mm tall, 240 mm wide and 463 mm deep and weighs 22.7 kg.

Engineering and use context

The main section vents through rear-firing Tractrix ports, while the sealed height unit works independently of that bass reflex chamber. Klipsch says the larger outer horn dimensions extend the range of controlled directivity, and the woofers use trickle-down technology from the Reference Premiere series, with steeper cone angles and extra ribbing to reduce breakup. Cabinets are made of reinforced 19 mm MDF, braced with a new layout and wrapped in scratch-resistant vinyl. Fasteners are concealed, the horn runs to the cabinet edges and the magnetic grilles sit low on the baffle, and injection molded feet with screws are included. Compared with the R-600F, the tower is 77 mm deeper and 4.1 kg heavier, while height and width stay the same. In the 5.1.4 and 7.1.4 packages the pair of R-605FA towers supplies two of the four height channels.

Pairing

Each tower has two independent inputs, both single gold plated binding posts, one for the main section and one for the height module. That means an AV receiver needs a front channel plus a height channel per speaker, so a pair uses four amplifier channels in a Dolby Atmos layout.

Alternatives

The Klipsch R-600F is the same Reference tower without the elevation module, with hidden rear connections for adding Atmos speakers later.
