Hi Craigslist,

Polk Audio Monitor RTi 28 Series Bookshelf speakers.

We Upgraded our home cinema surround system so this is your chance to get a steal on our lightly used Polk Monitors.

These Bookshelf speakers are more clear and powerful than the Bose Cube Speakers, Boston Acoustics Monitors and that is why we went this route and you will love this system as much as we did.

We compared all of the other manufacturers including Polk, JBL, Definitive Technologies, Sony and Bose but these just made the most sense to pay a heap of money for.

The Magnolia sales Person at Best Buy recommended these as speakers for my office and man was he right!!!

We bought these at Best Buy and paid just over $400 for the pair. They are still selling on eBay for $200+
I’m selling them this low as we got our new system in place and just don’t need these anymore.


Width 7 in
Depth 9 in
Height 12 in
Weight 14 lbs

So this is a great deal.

I’m selling some things to free up space in my garage so that we can park our car in it.
I am not currently interested in any trades and am firm on my price. I hope you can understand and appreciate that 🙂
If you see the ad it is still available, I am really good at removing my posts after I have sold something right away.
You will have to pick them up at Blue Diamond and Durango, I may be able to meet you at Flamingo and 215 in the late afternoons if that works out.

Send me a text or a call at show contact info
when you are ready to come pick them up

Have a Beautiful Day Craigslist.

Here are some more details on them:

Polk’s Monitor Series has been the gold standard of speakers since the 1970’s. This current generation features clear, accurate sound with strong bass and exception aural imaging. Polk made the enclosures out of MDF to be of a uniform density and not resonate. They’ve also included ¾” thick baffles to help produce clear lifelike sound.

The two 5.25″ cones are made from a bi-laminate composite for an optimal balance of weight and rigidity. The small driver delivers a wide open sound and exceptional responsiveness. The 1″ tweeter is a fabric/polymer composite the responds swiftly to the high efficiency Neodymium magnet. The crossovers between the drivers use Mylar bypass capacitors to let all of the details in the higher frequencies shine through.

No matter how good they sound, they have to look good too. Their contemporary look complements today’s flat panel televisions and modern decorating styles.
