Polk Audio RTI A3 Review

Table of Contents

Polk Audio RTI A3 is a mid-sized home theater speaker with 3 inch dome tweeters and 3-inch cone woofers. It includes a 10 inch subwoofer for low frequencies. The speaker’s audio response is 48-22,000 Hz and its impedance is 8 ohms.

The RTI A3’s tweeter and woofers produce a balanced sound. The speakers use a new aluminum finish and rubber surround on the back of the cones. The RTI A3 is the third RTI speaker to include this elevated support, which has been added to absorb vibration from its large drivers.
Polk Audio is an American audio electronics company which was founded in 1972 by John P. Bass. Polk Audio pioneered the development of high performance audio speakers for home, business, car and wireless applications.

The RTI A3 uses 3-inch polymer composite cones with rubber surrounds to produce deep bass and clear midrange sounds. The driver has a separate tweeter that produces high-frequency sounds. Both these features work together to create balanced sound; low-end frequencies are not too loud while the mid-frequency does not sound flat.

Directly on the back of the RTI A3 are two metal spikes. They are used to support the speakers which creates an elevated surface area to absorb vibration from the highs.

Polk Audio RTI A3 speakers will give you a clear and balanced sound that is perfect for mid-sized rooms and home theaters.

The RTI A3’s frequency response is wide and will cover up to 22,000 Hz.

Design & Structure

The Polk Audio RTI A3 is also very versatile. The earpads are quite large, providing a comfort that is rarely seen in other models. In addition to this, these headphones have been specifically designed to be comfortable to the point that you will barely notice them while wearing them. This naturally leads to increased mobility and prolonged use of headphones.

The only difference between the standard A3 and its Pro counterpart is the upgraded audio cable. This could just be an aesthetic change, but it does have a much bigger impact on the overall performance of the headphones. The upgraded cable is detachable, which means that the headphones can be comfortably stored in your bag or even backpack without any worries. This is due to how small and compact they are; you will hardly notice them during travel.

Another big difference between the A3 Pro and the standard model is their durability. One major factor that makes this model last longer than others is its hardy design.
