General information of the Polk RTI A3

It is a fact that a speaker like the A3 is very hard to miss. It is basically the largest Polk bookshelf speaker. This is exactly why it has the performance and the sound of a floor-standing speaker. Most importantly, it features an excellent 6 ½ woofer, with Dynamic Balance.

It also has a 1-inch dynamic balance dome-tweeter providing excellent sound. If you are not amazed yet, we should mention that it can handle an incredible 150 Watts of power.

What do all these numbers mean for you as an audiophile? Well, one thing is sure – having such a powerful speaker in the comfort of your home means that you will get a professional home theatre system setup for a very affordable price.

It also means that it is perfect for discerned stereo lovers and kicking out some volume. It weighs around 16 lbs, making it a perfect fit for almost any surface, although bear in mind it’s a bit bigger in size than some of the others.

So, if you have decent space on your shelves or listening room and you are on a bit of a budget, the A3 bookshelf speaker is possibly the best way to get high-quality audio for a fraction of what you would normally pay.

Features of the Polk RTI A3

We have to start by stating a few of the most important features (that may just sweep you off your feet). The RTI A3 has a ton of features usually found only in pricey speakers. The incredible Dynamic Balance polymer composite and the silk/polymer tweeter are just some of those.

In addition to this, the Polk features PowerPort tech which increases bass response. This also prevents unwanted distortion, leaving you with just the perfect sound. Moreover, the A3 also has an 8-ohm impedance and nice, bass-reflex ported design. Its extraordinary frequency response ranges from 50 to 26,000 Hz.

Design-wise, there are a few things that you will notice. First of all, the Polk has a beautiful, real-wood veneer finish, which makes it perfect for both modern and vintage-looking interior. In addition to this, it has the perfect size to actually fit anywhere, without it looking bulky or taking up room space.

It also comes in two colors – cherry and black. In the case of the RTI A3, what you see is what you get. So, as long as you think it will be a good match, it very likely will be.

In the end, you will end up with a high-quality and modern-looking speaker for only a fraction of what you would normally expect to pay, and we think that’s pretty awesome.

Alternatives to the A3

1. Dali Zenzor 3

If you are looking for an alternative to the A3, you can purchase the Dali Zenzor 3 instead. This bookshelf speaker comes from an award-winning series by this brand. It features a soft dome tweeter, wood fiber cones, and DALI drivers which ensure low loss construction. The cabinet’s design allows it to produce a deep bass sound, but this loudspeaker is still small enough to fit in a close enclosure or cabinet.

2. Bowers & Wilkins 606

Another option is the Bowers & Wilkins 606 speaker, which has a 52 – 28k Hz frequency response and 88 dB sensitivity. Weighing at 15.2 lbs, it’s a little lighter than the A3. Its design is smaller than the A3 so you can fit it in a narrower space.

3. Sony SSCS5

Last but not least is the Sony SSCS5 speaker. These bookshelf speakers have a 3-way, 3-speaker bass-reflex system with high-resolution audio that makes it one of the best products for its price range. With super tweeters, your soundstage will feel bigger too.


We have to sum up our review of these bookshelf speakers with a few thoughts. Aside from the excellent connectivity, among other features, the A3 makes sure that even audiophiles on a budget can enjoy high-quality stereo in their home – even those with larger budgets should seriously consider this speaker.

The RTI A3 is something we definitely recommend having on your list of must-have pieces of audio gear. There may be other options you can check out for your room, but this one is already great for listening to music and relaxing. What more can you ask for? The A3 is a piece of audio equipment that has a lot of features for a very friendly price tag.
