Speaker Design

Polk has made sure that the Polk S30 and the Polk S35 have both style and sound quality. They have a curved design, giving them a softer look to others. The grilles are anti-diffraction and have magnets so that you can easily remove them.

Power Port Technology

Power port technology is a patterned technology that comes with both the Polk S30 and the Polk S35. There are small ports at the back of the speakers that allow for enhanced bass.

The Tweeter

The tweeters of the Polk S30 and the Polk S35 are the standard 1-inch size. They are high-resolution terylene tweeters.

Crossover

The crossover is a crucial part of a speaker as it divides the unfiltered audio signals into high and low frequencies. The Polk S30 and the Polk S35 have precision crossovers with a crossover frequency of 2.5KHz.

Nominal Impedance

Most speakers have a nominal impedance of 6 ohms or 8 ohms, some will have 4 ohms. Though many feel this doesn’t reflect the quality of the sound, it does determine how efficiently they use power. The Polk S30 and the Polk S35 use 8 ohms.

Binding Posts

The connectors of the Polk S30 and the Polk S35 are single gold-plated 5-way binding posts. This ensures that both the sound information and the power can effectively pass to the speakers.

Warranty

The Polk S30 and the Polk S35 come with a 5-year limited warranty, which is actually quite impressive compared with many speakers.
