Frequently asked questions
Can I use the RP-600M II as a center channel speaker?
You can, but it is not ideal. The RP-600M II is a bookshelf speaker measuring 7.95 inches wide and 15.8 inches tall. A center channel like the RP-504C II is wider, at 32.1 inches, to cover a broader horizontal angle. This design ensures dialogue stays anchored to the screen rather than coming from a narrow point.
Which speaker is heavier, the RP-600M II or the RP-504C II?
The RP-504C II is significantly heavier. It weighs 36 pounds, while the RP-600M II weighs 18 pounds. The center channel is more than double the weight of the bookshelf speaker. This extra mass may provide better stability for a TV stand, whereas the lighter bookshelf unit is easier to move onto smaller shelves.
What are the physical dimensions of the RP-600M II?
The RP-600M II measures 15.8 inches in height, 7.95 inches in width, and 13 inches in length. These compact dimensions make it suitable for placement on standard bookshelves or speaker stands. Its smaller footprint allows for flexible positioning in compact rooms without dominating the visual space.
What are the physical dimensions of the RP-504C II?
The RP-504C II measures 6.87 inches in height, 32.1 inches in width, and 15.1 inches in length. Its wide width is designed to fit under most modern televisions. The low height ensures it sits flush with TV stands, providing a clean look while directing sound toward the listening position.
Are the RP-600M II and RP-504C II compatible with the same amplifiers?
Yes, both speakers share similar technical foundations. They both feature LTS titanium tweeters and Cerametallic woofers. They also both include bi-wiring options and removable magnetic grilles. This similarity means an amplifier that drives one effectively will likely handle the other without issue, provided the amp supports bi-wiring if you choose that setup.
Does the RP-600M II come in walnut finish?
Yes, the RP-600M II is available in a walnut finish. The specific model listed is the RP-600M II Walnut. This wood grain appearance suits traditional or warm-toned home theater environments. In contrast, the RP-504C II is typically finished in black to blend with most television bezels.
Which speaker is better for a wide TV setup?
The RP-504C II is better for wide TV setups. Its 32.1-inch width covers a broader horizontal dispersion pattern than the narrow RP-600M II. This design keeps dialogue centered and clear across a wider seating area. The RP-600M II is better suited for stereo pairs or surround channels where precise imaging is key.
Can I bi-wire both the RP-600M II and RP-504C II?
Yes, both speakers support bi-wiring. The product data confirms that they share bi-wiring options. This allows you to run separate speaker wires for the tweeter and woofer terminals from your amplifier. Bi-wiring can potentially reduce interference between high and low frequencies, enhancing clarity for both the bookshelf and center channel models.
