Vanguard Caldera 10 Duality

Once this unit is hooked up and balanced, its tough to beat for value. It makes cheap speakers sound better and better speakers punch way above their weight class. Very solid and versatile piece of kit. Glad to own it.

I purchased the this little subwoofer after watching several YouTube videos where the reviewers were impressed by the build quality and sound. With a 3 year warranty, I felt I had nothing to lose, so I bought it. When I hooked it up, something wasn’t right, so I called Veri-Fi Audio customer service and left a message. The owner of the company soon returned my call and walked me through some steps which had the sub working perfectly. I am very happy with the sound of this unit and plan to keep it. I am even more impressed with the service I received. Dedication to customer satisfaction is rare these days, and Mark from Veri-Fi Audio has made me a life-long fan! I will be buying more products from them soon.

Unbelievable for the price!

This is an excellent purchase for the price. It added the additional bass I was looking for and has its own volume and bass dials to adjust to your taste.

Over the years, I have put the majority of my audiophile / videophile time and money into the audio side of things. On the video side, I have a great LG TV / Monitor with a decent amp and speaker combo for sound. On a lark, I decided to pull the trigger on a Vanguard Caldera 10 sub, figuring that for the price and with Vera-Fi’s generous return policy, I couldn’t go wrong. Frankly, and in spite of the many favorable reviews, I really expected nothing more than thumpy, one note bass.

Surprise! The VC10 is tight and tuneful and highly adjustable. I was able to dial in the sub quite easily to add the bottom octave / octave+ to my video system, without overblown low-end out of sync with the rest of the frequency spectrum. It’s a remarkable phenomenon, but as I have experienced with a much more expensive sub in my audio system, adding the bottom octave or two somehow brings a greater clarity to mid and high frequencies. Part of this I suppose is the fact that I can eliminate the bass boost on my main speakers I had dialed in an attempt to get more satisfying sound. The mains are not working as hard now with the sub in place, greater clarity is the result, or so it seems subjectively.

Anyway, this sub is a winner. Can’t go wrong in my humble opinion…

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.

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.

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.

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.
