Now, it’s time to discuss the differences in a deep manner so that you can understand both of the speakers well. 

A Detailed Comparison of Common Features 

Ultimately, understanding the differences between speakers helps you make a decision based on your personal sound preferences, room size, power considerations, and bass response preferences. 

Choosing the right speaker will result in a more satisfying audio experience, which is also applicable when choosing between KEF Q750 vs LS50 meta. Let’s jump onto the detailed discussion of the common features at this point. 

Feature 1: Dimensions 

The Klipsch Heresy IV has a height of 63.01 cm, a width of 39.37 cm at its maximum and a depth of 33.66 cm. Then, the weight of this speaker is 45 lbs. These dimensions indicate that the Heresy IV is relatively compact and designed to fit well in small spaces.

On the other hand, the KLH Model 5 measures 87.0 cm (with a riser base), 66.0 cm (without a riser base) in height, then 35.0 cm in width, 33.0cm including a riser base, and 29.0 cm without a riser base in depth. Additionally, it has a weight of 52 lbs considering the without base the weight is 44 lbs. 

The differences in dimensions suggest that the Model 5 is larger and taller compared to the Heresy IV, making it more suitable for larger rooms.  

So, it’s important to consider the room size and the size of the speaker. Because setting a small speaker in a big room won’t be effective enough and vice versa. A big room needs a larger speaker and a smaller speaker is effective in a small room. 

So, the dimensions of Klipsch Hersey iv make it particularly suitable for smaller rooms. Due to its dimensions and acoustic characteristics, it delivers impactful sound in confined areas.
On the other hand, the KLH Model 5’s larger size and powerful performance make it better suited for larger rooms. The total space of the room is also an important factor when picking between REL T5x vs T7x.

Go for KLH model 5 if your space is larger and Hersey iv for a smaller space. 

Feature 2: Frequency Response 

Frequency response refers to a speaker’s ability to accurately reproduce a range of frequencies. It is measured in hertz (Hz) and indicates the range of frequencies that a speaker can reproduce with a certain level of precision. 

The Klipsch Heresy IV offers a frequency response of 48-20000 Hz with a deviation of ±4dB. It can reproduce frequencies from 48 Hz on the lower end to 20000 Hz on the higher end with a slight variation in accuracy within a 4dB range.

The human ear can detect frequencies between 20 Hz and 20 kHz. So, choosing speakers with a flat frequency response is crucial to ensure clear and balanced reproduction of all frequencies in music.

In contrast, the KLH Model 5 has a wider frequency response of 42-20000 Hz with a deviation of ±3dB. In this range, the Model 5 is able to reproduce frequencies ranging from 42 Hz at the low end to 20000 Hz at the high end with greater accuracy within a 3dB range.

Compared to the Klipsch Heresy IV and the KLH Model 5, the difference is actually quite subtle, with only a 6dB difference.

Feature 4: Sound Signature

The Klipsch Heresy IV blows your mind with its lively and original sound signature. With an emphasis on energy and liveliness, it is known for its dynamic and engaging presentation. 

To understand the sound signature deeply, let’s look at the FR graph of this speaker.

The Klipsch Heresy IV leans towards a U-shaped sound signature. So, it has an emphasis on the bass and treble section, with a slight dip in the midrange. 

Conversely, the KLH Model 5 has a clear, transparent, and clean sound signature. So, you’ll be able to listen to more clear music. Now, let’s look at this speaker’s FR graph.

The KLH Model 5 speaker is known for having a relatively neutral or “flat” sound signature. A “flat” sound signature means that the speaker aims to reproduce audio without emphasizing or de-emphasizing any particular frequency range. 

This can result in a more balanced and accurate representation of the original audio signal, allowing for more natural and uncolored sound reproduction.

For audiophiles and people in the music production business, KLH Model 5 is ideal. Conversely, People who love a bump in the bass, and who prefer Electronic and Pop music will definitely appreciate the Klipsch Heresy IV.

Feature 5: Sensitivity 

In terms of sensitivity, the Klipsch Heresy IV exhibits higher sensitivity with a rating of 99 dB. On the other hand, the KLH Model 5 has a slightly lower sensitivity rating of 87.5 dB.

A higher sensitivity rating means that the speaker will be louder for a given amount of power. For example, a speaker with a sensitivity of 90 dB will be twice as loud as a speaker with a sensitivity of 80 dB when both are driven with the same amount of power.

To get the most out of your speakers, choose speakers with a high sensitivity rating. Your electric bill will be reduced as a result, as you will use less power to reach the desired listening level.

So, with the same power output, Heresy IV will produce a slightly louder sound and cost less to operate than Model 5.

Feature 6: Impedance

The impedance rating of Klipsch Heresy iv is 8 ohms which is higher than KLH model 5.  The higher impedance presents a slightly more resistant load to the amplifier. So, you need to match this one with an amplifier that can handle 8 ohms of resistance.

On the other hand, the KLH Model 5 has a slightly lower impedance, which indicates a less resistive load for the amplifier. In this way, the amplifier may have an easier time driving the speakers, increasing the volume levels, and transferring power more efficiently. 

So, getting an amplifier or receiver that generates more than 4 ohms will create distortion and also put pressure on this particular speaker system.

So, always try to match the impedance of the speaker with the amplifier and receiver. Regardless of impedance, both of the speakers will perform amazingly with the Klipsch Cinema 600.

Feature 7: Power Handling 

Klipsch Heresy IV and KLH Model 5 power handling capabilities differ significantly. Klipsch Heresy IV’s power handling specifications are 100W (continuous) /400W (peak), which indicates that it can handle moderate levels of power effectively. So 

On the other hand, KLH Model 5 offers a higher power handling specification of 200W (continuous)/800W (peak). That actually goes to prove that it can handle stronger power levels.

A speaker’s power handling indicates how much power it can handle before it is damaged. Matching your speakers’ power handling with your amplifier’s power output is important. 

Speakers with low-power handling may be damaged by an amplifier with too much power. Subsequently, You may not be able to hear enough sound if your speakers have a high power handling and your amplifier isn’t powerful enough.

So, in terms of power handling specifications, to run KLH model 5, you need twice the power source of Klipsch IV. Do remember that, a high energy power output will cost you more electricity bill 

Feature 8: Finish Availability

Klipsch Heresy IV is available in a variety of color finishes to suit a variety of aesthetic preferences. The available finishes are Satin Black Ash, Natural Cherry, Distressed Oak, and American Walnut. Various finishes are available to suit your interior design or personal taste.

On the other hand, the KLH Model 5 comes in different color finishes. The Model 5 is available in English Walnut, West African Mahogany, and Nordic Noir finishes. So, you are free to choose from a variety of elegant and stylish finishes depending on your desired aesthetic. 

Feature 9: Pricing

The price of Klipsch Hersey IV is a bit pricy. The slightly higher cost will be worth it if you want a premium audio experience. Alternatively, the KLH Model 5 offers an attractive option at a relatively low price. 

Those looking for affordable high-quality sound reproduction will find this product appealing. 

So, Which One is Better, Klipsch Heresy IV or KLH Model 5?
