HERESY IV FLOORSTANDING SPEAKER
Options:
First introduced in 1957, the Heresy, a three-way design, started out as a compact center channel speaker to accompany the Klipschorn® in three-speaker stereo arrays. The Heresy IV offers unparalleled sound quality from a relatively small speaker.
Features:
- Includes New 10-Year Warranty
- All-new K-702 midrange compression driver, featuring a polyimide diaphragm, for exceptional detail
- For the first time, the Heresy IV features a rear port for the most efficient, fastest air transfer in their class, which reduces port noise for punchier low frequencies
- K-702 midrange is mated to the K-704 Tractrix® horn for a wide coverage pattern
- K-107-TI titanium diaphragm high-frequency driver with an all-new wide dispersion phase plug for providing exceptionally even high-frequency dispersion
- All-new high fidelity network for truer to life sound, best-in-class efficiency, and power handling
- Klipsch Tractrix ports have custom-designed inner flares that help reduce air turbulence entering the port. Less turbulent air helps reduce port noise for cleaner, more powerful bass
- Available in a high-quality Satin Black Ash, Natural Cherry, Distressed Oak, or American Walnut wood veneer finish
- Designed & assembled in the USA
Even if you never turn them on, they are the first thing someone notices in a room — and when you do turn them on, their clean, crisp sound can impress even the most discerning speaker aficionados.

DESIGNED & ASSEMBLED IN THE USA. MADE TO ROCK.
With cabinetry that is proudly handcrafted in Hope, Arkansas for over 50 years, the Klipsch Heresy IV speaker is a testament to the quality Klipsch demands from each and every of its audio products.
Here's to 50 more years of Heresy.
THEY SAID HE COULDN'T
BUT HE DID IT ANYWAY
"The hell I can't," Mr. Klipsch said. "And that's exactly what I'm going to call it!"
WHAT'S NEW?
A REAR PORT
For the first time in its long legacy, the Heresy now features a rear port – improving low-frequency extension by almost 10Hz, for room-filling bass.
Utilizing Tractrix geometry, the all-new Heresy IV ports allow for the most efficient, fastest air transfer in their class, which reduces port noise for punchier low frequencies. Klipsch Tractrix ports have custom designed inner flares that help reduce air turbulence entering the port. Less turbulent air helps reduce port noise for cleaner, more powerful bass.
In addition to delivering smooth, dynamic and low distortion sound, the Heresy IV is available in a high-quality Natural Cherry, Distressed Oak, American Walnut, or Satin Black Ash wood veneer finish. A slant riser base is included for floor placement that can be removed for cabinet installations.

My Dog Loved It—Until It Stopped Working
Size: Large, Color: Ball-Red
I purchased this treat-dispensing dog toy for my German Shepherd, and for the first couple of days it worked exactly as advertised. When rolled or tossed, it made an engaging sound that immediately caught my dog’s attention and encouraged him to interact with the toy to get the treats out. He absolutely loved it.
Unfortunately, after only a few days, the sound feature stopped working. Then it mysteriously started working again for a short period, so I thought the issue had resolved itself. However, it has now stopped completely. No matter how much I shake, roll, or toss the toy, it no longer makes any sound.
I went out of town and didn’t realize the return window had passed while I was gone. By the time I returned, the return deadline had already expired, which was disappointing because I would have returned it when the problem first appeared.
Based on my experience, I cannot recommend purchasing this toy. While many of the reviews seem positive, perhaps I received a defective unit. It’s disappointing that it stopped functioning properly after barely a month of use.
That said, my dog genuinely enjoyed it when it was working, and I would appreciate it if the manufacturer would stand behind their product and offer a replacement as a courtesy. I would be happy to return the defective toy. If a replacement performed as intended, I would gladly reconsider my opinion.
For now, however, I am very disappointed with the functionality and reliability of this product.

The Only Thing He Hasn't TOTALLY Destroyed
Size: Large, Color: Ball-Blue
I've spent my hard earned money on SOOOO many "indestructible " toys. This one is actually pretty good. It has a duck sound inside for when the pet rolls the ball to get the treats. I didn't use it for the treats. I gave this toy 4-stars because my dog broke the sound box while chewing it. We pulled the pieces out and he LOVES it. Great for play,and comfort. Sometimes, he sleeps with it. I guess you could say it's his favorite 😍.

Great balls of fun!
Size: Large, Color: Ball-Red
One of the best toys that was ever made! My wife likes to put little treats in there and I'll bat the ball around. The room gives their hours of entertainment. She puts little things like hands of corn i
