NHT


The NHT SW2P subwoofer system, paired with the NHT MA-1 mono amplifier, represents one of the most distinctive modular subwoofer designs of the early 1990s. Created by the American loudspeaker company Now Hear This (NHT), the system was designed to provide accurate, musical bass extension while offering flexible integration with both stereo and home-theater systems. Rather than building the amplifier directly into the subwoofer cabinet, NHT opted for a separate subwoofer and external amplifier/crossover, allowing greater placement flexibility and improved heat management.
The SW2P system centers on the SW2 subwoofer, a compact 10-inch driver housed in a vented 16-inch cube enclosure finished in NHT’s signature gloss-black laminate. Despite its relatively small size, the design was engineered to extend low-frequency performance into the low-20 Hz range, enabling it to reproduce deep bass notes that smaller bookshelf speakers cannot handle on their own.
NHT originally developed the SW2 series to complement its popular satellite speakers such as the SuperZero and SuperOne. When paired with those speakers, the subwoofer helped create a full-range system capable of delivering powerful low frequencies while preserving the clarity and imaging of compact monitors. According to technical descriptions, the SW2 could extend the low-frequency response of compatible NHT speakers to –3 dB at roughly 21 Hz, an impressive figure for a relatively small enclosure.
Driving the subwoofer is the MA-1 amplifier, a dedicated single-channel power amplifier and electronic crossover specifically designed for the SW2. The amplifier was engineered by NHT designer Ken Kantor, who focused on achieving accurate crossover integration and stable power delivery for the subwoofer system. The MA-1 provides 80 watts of continuous power into 8 ohms, with dynamic peaks up to about 120 watts into lower impedance loads.
One of the MA-1’s defining features is its flexible crossover system. The amplifier can route signals to the main speakers while simultaneously sending low-frequency information to the subwoofer, making it possible to integrate the SW2P into systems without a dedicated subwoofer output. The crossover can be set to several frequencies—including 50, 80, or 110 Hz—allowing users to tailor the blend between the subwoofer and their main speakers for optimal room response.
The MA-1 also includes both speaker-level and line-level inputs, making the SW2P compatible with a wide range of amplifiers and receivers. This versatility was particularly useful in the early days of home theater, when many systems lacked modern bass-management features.
Review coverage of NHT’s SW2 system highlighted its compact size and strong bass performance relative to its footprint. In an evaluation of NHT’s satellite/subwoofer systems, Stereophile noted that the SW2 was a “true subwoofer with response down in the low twenties,” emphasizing that the small 16-inch cube could deliver deep bass without visually dominating a room.
Another technical review noted that the amplifier and subwoofer combination could produce “levels exceeding 108 dB SPL,” more than enough output for typical domestic listening environments and movie soundtracks.
Today, the SW2P with MA-1 remains a respected vintage subwoofer system among enthusiasts. Its modular design, compact footprint, and musical bass response make it a practical companion for classic NHT loudspeakers and other compact audiophile monitors.

There’s something undeniably magnetic about vintage audio gear. The tactile weight of milled aluminum knobs, the warm glow of dial lamps, and—above all—the rich, analog sound that today’s sterile streaming boxes can’t quite replicate. But time is merciless: capacitors dry out, switches oxidize, and those gorgeous walnut cabinets lose their sheen. That’s where the art (and science) of our vintage audio refurbishment comes in.
Why Vintage Audio Still Matters
In the golden era of hi-fi—roughly the mid-1960s through the early 1980s—companies like Marantz, McIntosh, Pioneer, Sansui, and Technics were engaged in an arms race of build quality. This was before cost-cutting plastics and disposable designs; amplifiers were over-engineered, receivers were works of art, and turntables were precision instruments.
Owning one wasn’t just about sound; it was about status and permanence. These machines were built to last a lifetime—or two. The irony? Decades later, they often do, provided they’re given the care they deserve.
The Philosophy of Refurbishment
Refurbishment is not just about fixing; it’s about preserving authenticity while ensuring reliability. The goal is to keep that lush, analog character alive without compromising safety or sound quality.
Some enthusiasts chase museum-level originality—keeping every factory component in place. Others opt for sympathetic modernization, upgrading parts that never existed in the ’70s to improve performance. Both approaches can be valid; it depends on your vision.
The Turntable Store refurbishing process.. step by step
Step 1: The Initial Encounter
When we first meet a 40-year-old amplifier, we resist the urge to plug it in right away. That dusty Marantz 2270 might look gorgeous, but old electrolytics and brittle insulation can short instantly under full voltage.
Instead:
Tip: A faint musty smell? That’s often the scent of old phenolic boards, not trouble. But a burnt smell? That’s trouble.
Step 2: Deep Cleaning & Control Detox
Dust is the enemy of good sound, that is why we clean the interior carefully with compressed air and a soft brush.
The real magic comes with switches and potentiometers. Over decades, oxidation builds up, causing scratchy controls and dropouts. A deep contact clean in each pot and switch, followed by vigorous cycling, often restores silky-smooth operation.
Step 3: Electrical Resurrection
This is where science meets art:
Step 4: Cosmetic Glory
Refinishing the walnut cabinet can transform a unit. We do use real wood oil or Danish oil, not polyurethane. We clean the glass dial carefully; those silkscreened letters are fragile.
Knobs? We polish with metal cleaner, but never use abrasives on anodized aluminum.
Faceplate lettering? We avoid harsh chemicals—just mild soap and a microfiber cloth.
Step 5: Calibration & Sonic Check
After the repair and cleaning, it’s time to dial in the performance:
When done right, the result is astonishing: a sound that breathes—liquid mids, velvet highs, and bass with a tactile presence that modern gear rarely matches.

Why It’s Worth It
The payoff isn’t just sonic—it’s emotional. Restoring a 1970s Marantz or Sansui is like bringing a classic car back to life. Every glowing dial lamp, every smooth rotation of a volume knob, connects you to an era when music mattered enough to build machines like this.
And when you drop the needle on your favorite record and hear that warm, enveloping sound, you’ll know: this wasn’t just a repair. It was a resurrection.
