I purchased this along with two flexus subs-100 and flexus surr-100. The system was easy to set-up with the included USB dongle, which gave it a solid connection without any drop out. After setting up the system, and using Dirac Live for room correction, I streamed some movies and watched some Blu-ray movies, I was completely blown away. The system brought out clear details in all the scenes, whether it's footsteps, bullets, door squeaking, deep breathing, sword clashing, fire cracking, and bass! having two subs makes such a huge difference, you could really feel the low end and the subs hit h

I wanted to get 2 soundbars to replace a 5.1 system in my family room and a 3.1 my home office. I was able to afford what was presented some of the best out there. Every product get some bad reviews so I did my best to pick the right product. I thought the Sennheiser Ambeo Max got OK reviews, but nothing negative about the sound. The product that shipped from the Amazon 3rd party seller was delivered used in a beat up box, poorly repacked, and obviously returned by the previous purchaser as defective. I returned it.For my larger family room I ordered the Nakamechi Dragon. A full system with 2
I want to start by saying that I have been a huge Klipsch fan for many years. I first fell in love with their ProMedia 2.1 PC speakers over 10 years ago that absolutely blew me away with their sound and bass quality! Since then I've referred many happy friends to those speakers and continue to do so, even though sadly, they are only available used on eBay now. I later purchased multiple Klipsch speakers and subwoofers and continue to use them to this day.Many years later they all still perform like the day I bought them and are absolutely the best speakers I've ever owned, and I've owned plent
Listen, you’ll see a lot of reviews that start with, “I never leave reviews…”, but you can check me out, I think I’ve left 5 reviews in the past 10 years. If I like it, I leave a review.This soundbar is amazing. I used to sell electronics and I went in with very low expectations knowing the soundbar market, but I’ve had nothing but admiration and success with Klipsch products. So, I decided we finally needed the upgrade for family movie night.The soundbar is heavy. Solid build quality. I had no doubts from Klipsch. I decided to go with the grey/walnut color scheme and it is gorgeous. I totally
SUMMARY - Soundbars struggle to satisfy your craving for good stereo music AND dramatic cinema sound. The Flexus Core 300 takes a shot at this and comes as close as possible within the physical limitations of a soundbar. But this requires the assist of an external subwoofer and surround speakers for enhancing bass and spatial separation. Once you have such a package in place, I believe the Flexus Core 300 is perhaps the best option available for an all-round sound system in a soundbar format. Now for the essential details that matter to most folks.THE SYSTEM - Klipsch sells the soundbar, subwo
What a disappointment. Klipsch speakers always seemed a little bright to me with a very slight level of distortion in the high frequencies that was actually a little annoying, and low frequencies were always not that great. This was the main reason I never purchased any of their products. I recently decided to purchased the Klipsch Detroit Bluetooth speaker, as I could return it if I did not like it and it was a great price. It still has the signature high frequency issues, but they do not occur that often, and overall that speaker, at the right volume, with the right source material, can soun
Purchased 2 of these.The good- Overall great sound. Solid & noticeable bass from the little woofers. If you want some bass and don't have space for a sub this can totally work and you'd be happy. Great flexibility as you can run the wireless subwoofer from Klipsch and any wired version of your choice. This is overall the reason why I choose the unit.The bad- Dolby Atmos no where near on par with some of the big names. The first soundbar's wired connection went bad within a few months. I should have contacted Klipsch but I didn't. That's 100% on me, I just decided to use the unit in a room wher
I’ve been looking for a soundbar that delivers real surround, not just wide stereo. My search started with the Nakamichi Dragon 11.4.6 — an incredible system on paper. But after checking my room layout, I realized it wouldn’t work. I have no left‑side wall for reflections, and my media furniture has tall sides that would block the Dragon’s side‑firing drivers. I didn’t want to rearrange the entire room just to fit a soundbar.So I kept researching and eventually chose the Klipsch Flexus 200. I skipped the Flexus 300 specifically because the 200 has no side‑firing speakers, which makes it ideal
