Description
Description
An X-traordinary Leap in Sound. Meet the Magnepan 3.7x.
When it comes to sound reproduction, the Magnepan 3.7x doesn’t just raise the bar—it redefines it. Born from the legacy of the revered 3.7i and meticulously re-engineered as part of the exclusive X-Series, this speaker is what happens when Magnepan asks, "What if we didn’t compromise at all?"
The result? A speaker that turns every listening session into a front-row experience. With enhanced components, refined crossovers, and obsessive attention to driver balance, the 3.7x offers jaw-dropping clarity, tighter control, and sound so vivid you’ll wonder if your favorite band set up in your living room.
If you're looking for a speaker that embodies excellence, precision, passion, and that just-right mix of scientific obsession and musical soul, the 3.7x is your match.

X-treme Engineering: What Makes the 3.7x Different than the 3.7i?
Magnepan's 3.7x is a bold evolution from the 3.7i, and you’ll hear it the moment the music begins. The X-Series treatment overhauls the crossover network, capacitors, and resistors for improved energy flow and more precise driver integration. This isn't just a small upgrade—it's a meticulous overhaul.
Better Capacitors (Yes, It Matters!)
Capacitors are the unsung heroes of sound quality, and the 3.7x doesn’t mess around. Every capacitor in the crossover network is made from copper-rich polypropylene and individually tested to within a fraction of a percent. Each capacitor bank is built, tested, and re-tested until Magnepan’s engineers are 100% confident they’ll match perfectly between the left and right channels. The result? Flawless imaging, precise detail, and a smooth frequency response from top to bottom.
Better Coils (Inductors, But Cooler)
The 3.7x’s crossover uses air-core, bobbin-wound copper coils made in-house at Magnepan. Unlike the generic "off-the-shelf" inductors you’ll find in other speakers, these coils are tested for inductance, resistance, and “Q value” (that’s coil-speak for "how good it is") to absurdly tight tolerances. Once they’re soldered onto the crossover board, they’re tested again to ensure the left and right channels are perfectly balanced. More precision means less distortion, better energy flow, and pinpoint instrument placement.
Better Resistors (Why Resistors Matter)
Not all Magnepan models use resistors, but for the 3.7x, they’re a necessity. Instead of using one large resistor, Magnepan splits it into two smaller, parallel resistors. This allows for tighter control, more stability, and less heat buildup. Each pair of resistors is tested and matched to within five-thousandths of a percent (yes, thousandths). The result? Every 3.7x sounds identical, whether you’re in New York, Tokyo, or Paris.
Better Wiring (Shorter, Cleaner, Copper-ier)
Here’s something you’ll love if you’re a purist. All internal wiring on the 3.7x is 15-gauge solid copper—no flimsy, mass-market wire here. The crossover layout has been redesigned to reduce excess wire, shorten signal paths, and remove unnecessary connections. Less wire = less resistance = better sound. Every connection (except for the terminal screw) is silver-soldered, giving the signal a clean, uninterrupted path from source to speaker. Translation? Pure, uncolored sound.
Better Connections (This is Love)
Every connection point in the 3.7x is built to be as solid as possible. No loose, crimped connections here. From the crossover to the driver, everything is locked, soldered, and secured.
Better Materials (It’s What’s Inside That Counts)
From the nameplate components to the capacitors, coils, and wiring, only three metals are allowed inside the 3.7x: copper, silver, and gold. Why? Because they conduct electricity better, last longer, and sound cleaner. No shortcuts, no cheap materials, no compromises.
The Listening X-perience
You know that feeling you get when a live performance hits you right in the chest? That's the 3.7x. The hallmark of planar magnetic technology is its ability to create a wide, open soundstage where every instrument has its place. But with the 3.7x, you get laser-sharp imaging, richer textures, and lifelike presence. Close your eyes, and you’re at the concert.
What makes it different from the 3.7i? The 3.7x delivers even more clarity, especially in the high-end detail, thanks to tighter tolerances and superior crossover components. Subtle musical details—like the scrape of a bowstring or the shimmer of a cymbal—are clearer and more distinct. Bass hits harder but never gets muddy, while midrange warmth feels like a cozy, well-worn blanket.
Tailor Your Look: Trim Options
The Magnepan 3.7x offers a variety of trim options to complement your existing décor. Choose from a classic black, off-white or classic white grille cloth, or a more contemporary neutral grey.

Customer Reviews
I just replaced my 3.7i Maggies with the 3.7X. I was completely suprised at the level of overall improvement I got over an already great speaker. The dynamics are so much better and every voice and instrument is more defined in it's own space. A more balanced tone and greater stage depth are easily noticable. Mike has once again pointed me in the right direction. It's impossible to say enough about the service from The Listening Room. You just Can't go wrong.
