EISA Awards: Award-Winning Product

Each year, dozens of European journalists gather to select the best electronic products of the year. Awarded by a diverse and impartial jury, the EISA (Expert Imaging and Sound Association) awards recognize exceptional products for their performance, design, or ergonomics.

Overview

The Polk Reserve R400 center speaker features two 6.5’’ Turbine cone woofers and a 1’’ Pinnacle tweeter. This high-end speaker ensemble delivers the purest and most intelligible voices for all your favorite movies, TV shows, and video games. The new patented X-Port system eliminates cabinet resonances for the ideal entertainment experience.

Better Sound

The center speaker plays a crucial role in any home theater system. The Reserve R400 utilizes the latest version of our best drivers to deliver consistently clear, detailed, and intelligible dialogue, no matter where you are seated in the room.

New X-Port Technology Integrates an Eigentone Filter (ETF)

For natural, distortion-free bass. Consisting of a set of specially optimized closed-tube absorbers designed to capture and eliminate distortions from a speaker, the X-Port system ensures that the upper bass and midrange remain free from any resonance originating from the speaker’s port and cabinet, resulting in sound that always remains smooth and ultra-detailed.

User reviews

Eric

I am delighted with this center speaker. Replacing a very good Focal CC900, it allows me to upgrade my system in line with my excellent Polk R600 towers as well.
This speaker, with its Hi-Res certification and EISA award, offers outstanding value for money.
I highly recommend them—the sound is magnificent and the vocal clarity is top-notch.

Je suis ravi de cette enceinte centrale. En remplacement d'une très bonne focal cc900, elle me permet de faire évoluer mon système en adéquation avec mes colonnes Polk R600 excellentes, elles aussi.
Cette enceinte avec la certification HiRes et le nomination EISA bénéfice d'un rapport qualité/prix excellent.
Je vous les conseille , le son est magnifique et la clarté des voix au Top.

I wasn't familiar with the brand and wanted to try something new. Coming from a Focal SIB XL as a center speaker, there is obviously a significant difference in terms of sound and size. I was a bit worried that my Yamaha RX-A2A amp would be insufficient to properly drive this speaker (which has a rather low sensitivity rating), but no issues in practice. It's lively and powerful, and the sound is much more enveloping than the Focal. Very happy with my purchase, and combined with Polk R200s, my front soundstage has been transformed.

Je ne connaissais pas la marque et je voulais tester quelques chose de nouveau. Venant d'une Focal SIB XL en centrale, forcement il y a un écart significatif au niveau du son et aussi de l'encombrement. J'avais un peu peur que mon ampli Yamaha RX-A2A soit insuffisant pour driver correctement cette enceinte (annoncé avec une sensibilité un peu faible) mais aucun souci à l'usage. C'est vif et puissant, le son est bien plus enveloppant que celui de la Focal. Très content de mon achat et combiné avec des Polk R200 ma scène frontale est métamorphosée.

Eco-contribution of €0.75 included in the sale price.
