ALPHA PRIME & ALPHA DOG HEADPHONES
High-Performance Closed-Back Headphones with 3D Printed Cups
MrSpeakers’ Alpha Dog and Alpha Prime headphones are state of the art upgrades to the classic Fostex T50RP headphone. Both headphones use our ground-breaking 3D printed cups for optimum sonic performance and isolation, without excessive weight.
As closed headphones the Alphas are particularly useful for users requiring isolation from noise, or where an open headphone might disturb others such as traveling, at the office, in a library, etc.
Historically, closed headphones have delivered a small soundstage, often with congestion in the midrange and a sense of “cup” around the ears. With their unique 3D printed double-wall construction and our attention to internal cup tuning, Alphas lead the industry in isolation while offering a sound more closely associated with open-back headphones.
The primary difference between the Alpha Dog and Alpha Prime is that Alpha Prime uses our patent-pending V-Planar technology to increase compliance of the driver. Greater compliance translates to reduced distortion and extended frequency response, for the most open and dynamic sound we could create in a closed headphone. Alpha Prime has also been re-voiced for a more linear presentation through the spectrum.
Both headphones offer very smooth, detailed and dynamic sound that works well across a broad range of musical genres. We hope that should you choose an Alpha headphone, you’ll enjoy it a lot!
NOTE: The headphone stand is no longer included with Alpha headphones.
MrSpeakers' Alpha Prime headphone is built on the award-winning Alpha Dog 3D printed baffle and cup assembly. But we don't stop there, that's where we started.
Pure and simple, Alpha Prime was about tuning and improving the driver, and changing the voicing to reflect the improvements. And no, we won't say what we've done differently, but it took a LOT of work to do it. And we truly hope you'll enjoy it.V-Planar™ Driver Processing
Simply stated, a conventional planar driver is usually assumed to move as a flat surface. In reality, this is not possible as the driver substrate is inelastic and “locked” at the boundaries. As such, the driver will move more as an arced surface then a flat plane, as conceptually illustrated in Figure 1.
In simplified form, V-Planar technology addresses nonlinear driver motion by more deeply creasing the diaphragm to increase compliance. Much as pleats allow an accordion to expand and contract without stretching the fabric, the creases in the driver "open" slightly during larger excursions as illustrated in Figure 2. When the driver is processed, the resultant peaks and troughs are deep enough to maintain more of their physical structure even after the driver has been tensioned.
Alpha Prime vs. Alpha Dog
We know you're going to ask, and here's the answer. It's better. Across the board in our opinions. Faster, more detailed and textured mids, smoother highs, a better balance, and holographic soundstage and imaging, where every sound source is not only in the right place, it occupies the right space.
The Alpha Dog is a great headphone, especially at it's price. Alpha Prime is just a great headphone, and we hope those who decide to buy one will really, really enjoy it.
