Summit HiFi Pretium 15" Series Subwoofer

Built to Shake. Tuned to Perfection.
When Bass Becomes an Experience.

Not just deep.
Seriously powerful.

The Pretium 15 Series is Summit HiFi’s high-performance 15-inch subwoofer, engineered to deliver massive impact, room-shaking authority, and clean precision—without the big-league price tag.

One massive 15-inch long-stroke driver.
Relentless power.
Precision that hits hard and stays clean.

This is the kind of performance you expect from subwoofers that cost way more—then you see the price and think:
“Wait… are you serious?”

Press play, and the room responds. Bass slams with confidence, digs deep with control, and fills your space with pressure you don’t just hear—you feel. Tight when it needs to be. Brutal when you want it.

And here’s the truth:
These are expensive-level specs at a shockingly affordable price. Because at Summit HiFi, we don’t believe great bass should be out of reach.

Come on… what else do you want?
Power. Control. Precision. Value.

This is Summit HiFi. Truly amazing bass—done right.

Why Pretium?

Pretium is Latin for price, value, worth, and reward—a reminder that real performance isn’t measured by specs alone, but by what it delivers.

Most subwoofers excel at one. Very few deliver both.

Summit HiFi engineered Pretium from the ground up—combining a massive driver, intelligent DSP, professional connectivity, and real-world tuning flexibility—to deliver bass that adapts to you, your room, and your system.

No gimmicks. No inflated numbers. Just honest performance.

Pretium isn’t about louder bass. It’s about bass that’s worth it.
