Whether you're extending the low-end performance of your stand-mount speakers, adding punch and clarity to your tower setup, or bringing cinematic bass to your home theater, the Vanguard Caldera 10 delivers real-world high-fidelity performance at a price that won’t break the bank.

The Vanguard Caldera 10 is a self-powered, vented alignment subwoofer with a 10-inch driver, featuring a high-quality Class A/B amplifier and a robust toroidal transformer linear power supply. Designed for both performance and versatility, it accepts speaker-level and line-level inputs, with adjustable gain, frequency response, and phase reversal to integrate seamlessly into any audio setup.

  • Customizable Sound: Adjust gain and frequency to match your speakers with ease. High-level speaker inputs provide sensitivity starting at 71dB at 1m (2.83v RMS) with gain set at 12 o’clock, scaling up to match sensitivities as high as 95dB.
  • Extended Frequency Range: With a bass extension reaching 30Hz at -3dB and 27Hz at -6dB, and an adjustable upper range from 60Hz to 200Hz, the Caldera 10 is tuned to complement the dominant kick drum pulse at 52Hz for natural, impactful sound.

Stylish Design for Any Space

Housed in a sleek black cabinet with beveled edges and an etched finish that reflects light like textured steel, the Caldera 10 is as stylish as it is powerful. Its non-descript design integrates seamlessly into any room without drawing attention—letting your sound take center stage.

The Vanguard Caldera 10 is literally the giant killer

This little box put out impressively large-scale sound.

You’ll be impressed with how much this little sub can truly offer in terms of total system musicality.

This sub is quite musical, far from a boom-boom box; it renders with a musical heart.

The Caldera 10 actually increased the soundstage, giving the deep resonance that accompanies a massive hall.

Excellent

Nothing better at this price and I agree, you’d have to pay way more to get better or equal performance. Just prior to this I had demoed a JL Audio Dominion at five times the price and there was no contest between the two, the Vanguard was demonstrably better.
I use this for music only and paired it with some Gallo A’diva SE’s. IMPORTANT: this sub requires extensive break-in and didn’t sound its best until after about 100 hours and the change was dramatic.
The reason why the sub is so good for music is because it excels in medium and upper bass(where most music is played) yet still goes deep and clean providing a nice visceral and “chesty” feel that you expect with better subwoofers.
The sub is well-made, is not overly heavy and is easy to move around.

Incredible Performance on a budget

I got this subwoofer right off their site and am really impressed with the sound. I have it paired with two KEF bookshelf speakers and a Denon Home Theatre Receiver. Works super well in my setup.

Blown away.

At this price point, I doubt if you'll ever find another subwoofer that can compete with it. The base is clear sharp and full not muddy.

Surprisingly good for a low price!

I'm happy with how I could integrate a pair of these into my stereo system, so that they make a contribution the overall sound, but don't call attention to themselves. Bass got tighter, with more "texture" - as I had hoped. I used the high level hookup method.
