Nice sound, but...

No, I would not recommend this to a friend.

I like the sound but frequently when I change channels it starts a high pitched hum and won't stop until I either keep switching channels or turn it off and back on. Not real convenient.

Great Sound

Purchased this to go with our LG tv. Sounds great and I can use the tv remote to control the sound. No need for 2 remotes. It sounds like a true surround sound system without all the speakers and wires around the room.

Great purchase

Bought lg sound bar to provide sound for lg Oled 55 tv thru Bluetooth connection sounds great and like that it all connects together. Was disappointed that front speakers sold separately but would recommend purchasing this lg sound bar

Fantastic sound and feel. I love to just play the DTS title at the beginning of the 4K blurays, it's like sitting on top of the speakers in a movie theater. The air around the room literally vibrates when I crank up the volume. I have already turned on several friends and family to this great experience. If you love movies and the sounds in them, you'll love this soundbar.

Good sounds

Knie Price Match Policy

Low Price Guarantee

Found a lower price? No problem! We match all local competitors’ prices, just give us a call or email with what you’ve found

(815) 626-5631

Price Match Policy

We’ll match any local competitor’s price on an identical item. We’ll need to verify the price. Any store within 30 miles we consider “local” competitor.

Why just match the price, why not beat it?

In addition to our price match policy you get the advantage or highly trained sales staff, and our professional and experienced delivery team.  We won’t ask you to pay more, but we can’t  provide our advanced level of service and always beat our competitor’s pricing.

Why don’t you match ALL web prices?

There’s little risk in buying books and shoes online. Not so with furniture, appliances and electronics. We’ll match any local store (whether they offer Knie’s level of expertise or not), but there’s going to be a modest price difference between local and web-only stores. If you find a difference you feel is excessive, bring it to our attention; we want your business!

Our well trained sales professionals are also here to provide you with the information you need to make an informed decision on your appliance, electronics or furniture purchase.

How can Knie’s compete with national retailers?

We belong to the Nationwide Marketing Group, a collective of thousands of retailers like Knie’s across the country. Together we have more buying power than a top-ten national retailer, and we negotiate accordingly.

Give me the complete details.

    •    If you find a lower price on an identical item at a local competitor’s store or website, we’ll match it
    •    Pricing not listed on websites must be verified via phone, print advertisement or written quote
    •    May not be combined with other special offers not available at the competitor
    •    “Local” competitors are those in the same city or within 30 miles of a Knie location
    •    Limited quantity specials, closeouts, and damaged/as-is items are excluded
    •    We reserve the right to limit quantities


Knie's offers great quality Furniture, Appliances, Electronics and Mattresses at a low price to the Sterling and Polo cities and the surrounding areas.
