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.
Gear Patrol
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.

zelda‘s “indoor” ⚽️ ball!
Color: Squeaky Green, Size: Medium Size 2 (6")
zelda loves her soccer ball - because of the fabric “tabs”, and the way she treats her toys, we keep it inside. she loves to place all of her toys and bones on our bed, after they’ve been cleaned. this ball is perfect and soft enough to throw it down our steps, where she will run down, retrieve it, and bring it back to the bed.
it arrives deflated and comes with the pump and two needles - the pump is not the sturdiest and felt like it was not inflating, but after only having to reflate it once with a bit of air since receiving it ~5-6 months ago, it still holds up!

Small for a medium
Color: Red-Blue, Size: Medium Size 2 (6"), Color: Red-Blue, Size: Medium Size 2 (6")
I got medium.. and it does not look like a medium ball.. it’s rather small. It’s pretty sturdy and my dogs went crazy for it but it’s definitely not the size I thought it was going to be 😂 my dogs chewed one strap within 5 minutes of having it but they’re dogs and that’s what they do lol. I bought this to be an outside ball for them! It’s pretty light but that’s probably because it’s small. Not soft? But feels like a soccer ball. It also had no smell coming out of the box. Also comes with a pump and an extra thing to put in the ball to pump in case you lose one. I like these balls, I expect them to be chewed up because that’s what I bought them for! Fun for my dogs and they are! But the size… it is not medium and that’s the only reason for 3 stars 😂😂😂 Other then that I recommend, your dog will definitely love this! Inside or outside playing! Alone or with another dog!

Great toy for a GSD
Color: Blue Gray, Size: Extra Large Size 5 (9")
My GSD loves to grab the flaps and shake her head with the ball bouncing of the side of her head. This is her favorite toy. I thought she would puncture it but it has held up great since she likes to grab the flaps rather than biting the ball.

Energy burn
This interactive dog ball is a total game changer! The automatic rolling and bouncing keeps my dog entertained for long stretches, and the lights make it even more exciting, in the evening. I love that it’s rechargeable and waterproof, so we can use it both indoors and outside without worry. It feels durable and well-made, perfect for medium to large dogs. Also works great with toddlers.
