If you love hi-fi, this is the fun stuff.
In this video, we are comparing four speakers that all live right around the $3,500 per pair range, which is where you start stepping into real high-end audio. At this level, speakers are not just another part of the system. They are the foundation. Whether you are upgrading an older pair or building your first serious setup from scratch, your speaker choice will shape almost everything you hear.
But this comparison is not just about four boxes that make sound. These speakers come from some of the most important design philosophies in hi-fi history. We are talking about names like Paul W. Klipsch, Henry Kloss, Dr. Paul Mills, and Andrew Jones. Each one approaches speaker design differently, and you can hear those choices in the way these speakers present music.
First up is the Klipsch Heresy IV, one of the most recognizable speakers in American hi-fi. It is a three-way design with a horn-loaded tweeter, horn-loaded midrange, and a 12-inch woofer. It is also the most efficient speaker in the group at 99 dB, which makes it a great match for lower-powered amplifiers, especially tube amps. The Heresy has been around in one form or another since the late 1940s, and there is a reason it has lasted. It has punch, speed, energy, and a midrange that brings vocals and instruments forward in a way that feels alive.
Then we look at the KLH Model Five, a modern return of a classic Henry Kloss design. This is a three-way acoustic suspension speaker, which means it uses a sealed cabinet instead of a ported one. That gives the Model Five a tighter, more controlled approach to bass. It does not try to fake big bass with a bump at the bottom. Instead, it gives you a more natural, gradual roll-off that can sound clean, accurate, and balanced in the right room. With its paper woofer, paper midrange, aluminum dome tweeter, and included tilted stand, it has a vintage soul with modern execution.
Next is the Fyne Audio F502SP, a tower speaker from Dr. Paul Mills and the team behind Fyne Audio. This one brings a lot of the concentric driver magic that made classic British speaker design so beloved, but with Fyne’s own modern twist. The tweeter sits in the center of the upper 8-inch driver, helping the speaker act more like a point source. That gives it strong imaging, a cohesive presentation, and a sound that stays consistent as you move around the room. It also has serious low-end authority thanks to its dual 8-inch drivers and Fyne’s bass diffuser system, which helps reinforce the bass without making placement a nightmare.
Finally, we get into the MoFi SourcePoint 10 Master Edition, designed by Andrew Jones. This is a big standmount speaker with a 10-inch paper cone and a 1.25-inch soft dome tweeter placed in the center. Like the Fyne, it is a concentric design, but it has its own personality. The Master Edition adds an improved crossover and user-adjustable treble settings, giving listeners more control over how the speaker works in their room. It images beautifully, throws a wide and deep soundstage, and has the kind of bass foundation that makes the midrange feel rich and grounded.
What makes this comparison interesting is that all four speakers are trying to solve the same problem in different ways. The Klipsch Heresy IV gives you efficiency, impact, and horn-loaded excitement. The KLH Model Five gives you sealed-box accuracy and classic American balance. The Fyne Audio F502SP gives you a full-range tower experience with great coherence and room-friendly bass. The MoFi SourcePoint 10 Master Edition gives you Andrew Jones’ concentric design work in a bold, modern standmount speaker.
In the video, we talk through how each speaker sounds, what kind of room it may work best in, how much amplifier power you might want, and what makes each design special. At around $3,500, these speakers can become the anchor of a serious hi-fi system, so choosing the right one matters.
And because we like to keep things fun, there is a contest at the end of the video. Tell us in the comments who your favorite speaker designer is and why. We will pick a winner from the first 10 comments. The winner can choose either a $50 Upscale Audio gift code or two Upscale Audio T-shirts.
If you are trying to figure out which speaker could be the heart of your next system, this is a good place to start.
Thanks for watching Upscale Audio. We are going to treat your system like it is ours.
