Product Description

Powerful, Refined Bass at a Friendly Price

Low frequencies are the foundation of a full-range audio experience. 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.

Deep, Controlled Bass Without Compromise

At the core of the Caldera 10 is a 10-inch driver powered by a high-quality Class A/B amplifier with a robust toroidal transformer linear power supply. This combination ensures clean, powerful bass response, reaching down to 30Hz (-3dB) and 27Hz (-6dB). The high-aspect-ratio laminar flow slot vent eliminates chuffing, delivering smooth, distortion-free bass with every note.

Effortless Integration into Any System

The Caldera 10 is designed for maximum versatility, offering both speaker-level and line-level inputs, allowing seamless integration into any system. Adjustable gain, frequency response, and phase reversal give you full control to fine-tune the subwoofer to match your speakers and room acoustics.

Sleek, Compact, and Built for Real-World Performance

Encased in a sleek black cabinet with beveled edges and an etched finish that catches light like textured steel, the Caldera 10 blends effortlessly into any environment. Its compact footprint (13” W x 15” H x 16” D) allows for flexible placement without sacrificing performance.

Experience the Vanguard Caldera 10 and hear what real, uncompromised bass sounds like—powerful, refined, and built to perform at a realistic price.

Going from no sub to this bad boy is amazing

Going from no sub to this bad boy is amazing. Movies are next level, and I can enjoy my music on a whole other level! Also the Owner Mark is very helpful and responsive.

Very well made 10 inch subs! Buying the two Caldera 10 subs was a great decision

Very well made 10 inch subs! Buying the two Caldera 10 subs was a great decision. They really bring out space in the music and provide solid tonal support for the Scouts. They are an incredible value for the money. The design is very space efficient as at least in my house real estate on the floor is at a premium. They are small for the results you achieve.

Took some time to get here, but I am enjoying the quality of this product. It is plenty of bass for my space and I don't need much volume to make the room shake. Well worth the wait.

Great sound, shame about the auto mode

Great sound, much more musical than the DIY sub I was using before. It's just a shame that the auto mode switch isn't very well calibrated, so that it turns on and off unnecessarily during quieter parts of tracks. Also suffers from transformer hum which I'm having to do quite a lot of work to solve.

That said - for the price, still an excellent musical experience.
