Polk Audio Reserve R600 Floorstanding Speaker - White - Each

Larger Turbine Cone Woofers, a Deeper Reach

The Polk Audio Reserve R600 is a 2-way floorstanding tower and the flagship of the Reserve line, built around a 1-inch Pinnacle Ring Radiator tweeter and two 6.5-inch Turbine Cone woofers, crossing over at 2,700 Hz.

Polk rates sensitivity at 87.5 dB, and the cabinet accepts 8-ohm, 6-ohm, or 4-ohm amplifiers (4.0 ohms minimum) rated between 25 and 200 watts — an easy load for most integrated amps and receivers.

The cabinet is available in Black, Brown, or White, and each tower is sold on its own, so a stereo pair means ordering two, one for each channel of a stereo system.

Where the Larger Woofers Earn Their Keep

A Ring Radiator Tweeter Above Twin Turbine Cone Woofers

The 1-inch Pinnacle Ring Radiator tweeter uses the same ring-shaped diaphragm design found throughout Polk's Reserve line, extending high-frequency detail while keeping distortion low even at much higher output levels.

Below 2,700 Hz, two 6.5-inch Turbine Cone woofers take over, larger than the woofers in Polk's entry Reserve tower, moving more air for deeper, more effortless bass in a larger cabinet.

The Numbers, and What They Ask of Your Amplifier

Polk quotes a frequency response of 32 Hz to 50 kHz overall, with -3dB points at 43 Hz and 38 kHz. Sensitivity is 87.5 dB, and the cabinet accepts 8-ohm, 6-ohm, or 4-ohm amplifiers, with a 4.0-ohm minimum impedance.

The cabinet is rear-ported using Polk's Power Port 2.0 with X-Port design, shaped to smooth airflow and reduce chuffing as output climbs, even at the top of its recommended amplifier range.

Who Is This Floorstanding Speaker Best For?

• You want Polk's flagship Reserve tower, not just their entry model — larger 6.5-inch Turbine Cone woofers move more air for deeper, more effortless bass
• You want genuine high-frequency clarity from a ring tweeter — the same Pinnacle Ring Radiator technology used throughout the Reserve line
• You want a real choice of finishes — Black, Brown, or White, all ready to match a real room
• Your amplifier delivers a modest, easy-to-drive amount of power — 87.5 dB sensitivity and an 8/6/4-ohm compatible load suit amplifiers between 25 and 200 watts
• You want real floorstanding bass without a separate subwoofer — the R600 reaches to 32 Hz on its own. For the deepest home-theater effects, add one of our subwoofers and let the towers do what they do best

How Does It Connect to Your System?

Connect each tower to an amplifier or receiver's speaker outputs using the single pair of binding posts on the rear panel. An 8-ohm, 6-ohm, or 4-ohm amplifier all work, with a 4.0-ohm minimum impedance to plan around.

Since the cabinet is rear-ported, leave a few inches of clearance behind each tower before settling on a final position.

At just over 47 pounds each, plan for a firm, level floor and enough clearance to move each tower into final position before connecting cables.

Pairs Well With

What finishes the system around a pair of Reserve R600 towers:

• Integrated amplifiers — an easy 8-ohm load most integrated amps drive comfortably
• AV receivers — anchor a home theater front stage compatible with IMAX Enhanced content
• Speaker cables — connect to the rear binding posts
• Audio racks — house the electronics driving Polk's flagship Reserve tower

Frequently Asked Questions

How much amplifier power do I need?

Polk recommends amplifiers between 25 and 200 watts, compatible with 8-ohm, 6-ohm, or 4-ohm loads. At 87.5 dB sensitivity, most integrated amps and receivers in that range drive it comfortably.

Is the R600 IMAX Enhanced certified?

Polk lists the R600 as compatible with IMAX Enhanced content, alongside Dolby Atmos and DTS:X — a broad home-theater format list, though Polk's own materials describe this as compatibility rather than a separate formal certification.

How far from the wall should I place them?

Since the cabinet is rear-ported, give each tower some room behind it. Moving it closer to the wall adds bass warmth; pulling it out tightens and tames the low end.

What finishes are available?

Black, Brown, or White, all ready to match a real room.

What's the warranty?

Polk covers the Reserve R600 for five years against manufacturing defects, its standard warranty for passive tower speakers.

Do I need a subwoofer with these speakers?

Not necessarily. The R600 reaches to 32 Hz on its own, though a subwoofer can still add reach for home theater use.
