I was looking to upgrade my measly 8" subwoofer, that although had served me well, felt a bit lacking for my music enjoyment. I had heard whispers of a killer 10" sub from a brand I hadn't really heard of before, but was getting glowing reviews by respected people in the audiophile community. So I figured why not give it a chance and ended up ordering one of the 10" Vanguard Calderas. I was a bit concerned since I ordered whilst they were experiencing some shipment hurdles and unfortunately my order seemed to be affected. Alas, Mark and the wonderful guys at Vera-Fi were able to organize a way to upgrade me to their flagship 12" Caldera instead at no extra cost.
So, I finally got the 12" Caldera with its beautiful cherry wood finish and massive driver into my setup. Yes, the reviews don't lie. This sub hits deep and rumbles your space for pure satisfaction. I tested it with my electronic and hip-hop music catalog as well as some great movies such as 1917, Top Gun Maverick, and Heat to recreate that theater experience and it delivered. I'm not the most knowledgeable about the audio science behind a good sub, but this gets my full approval considering I'm not even running it at more than 50% gain. This is truly a superb deal in this audio hobby that seems to have no ceiling for how much gear can be priced for. In any case, I am 100% willing to get another if I could; at the very least I am all for supporting some of the coolest people at Vera-Fi!
I was not disappointed. This took a little longer to get than my bookshelf speakers. But once it finally arrived, I was pleasantly surprised with the perfect match. Great low end bass. Beautiful wood work, strong sturdy cabinet. They knocked it out of the park. Very happy customer.
It's hard to believe that a speaker this beautiful, sounding this spectacular is less than $500. I am impressed.
I've recently replaced my B&W 705 S2 standmount and B&W ASW608 sub by a new B&W 704 S3 floorstander. Incredibly good speakers, especially considering the price. The dual woofers reach down to 48Hz, but I still missed that last octave. I was looking for a suitable REL sub but after seeing so many good reviews about the Vanguard Caldera 12" Active Subwoofer I decided to give it a try. I thought it would be difficult to get one in the Netherlands. However thanks to Ace from Vera-Fi, he managed to do that; my sub arrived on location in 11 days. The price-performance ratio is out of this world. I thank Ace for all his efforts and Vera-Fi for an incredible deal.
I have had some excellent subwoofers in my time, and for music the Vanguard Caldera 12 is one of them. A small amount of the 'feel not hear it' bass is missing (when it is even present in the soundtrack) in some movies when compared to my current living room 500-watt RMS ported 12" sub (both compared when setup with Yamaha YPAO room correction at the same listening position in my bedroom). However that sub is 2.75 times the price of the Vanguard Caldera 12. That is a lot to pay for a small amount of bass not even present in all soundtracks. In music however, it is almost impossible to hear a difference in lowest frequency response. Plus, one is a black, cloth-covered tube that is ~40" tall, and the other is beautifully finished in real Rosewood veneer. Looks count, too in my book ;)
Excellent built quality, a ported sub that sounds closer to sealed sub and for only 348 euros? Insane but true, the Caldera 12 will sound just as good in my room for music or home theater, i cant recommend this sub enough! Go dual for bombastic room filling low notes imo. The only gripe i have is the auto on off which turns the sub off after only 10 seconds, i would recommend at least 1+ minute of inactivity to turn off so lets hope they boys in the lab will sort this out on the next batches! Excellent job Vera Fi team!
Great system -- purchased 5 scouts (one for center channel) and 12" sub. Scouts sound is clear and natural. Scouts and sub blend wonderfully. For music, the sub reproduces musical notes, not simply some deep thump other subs might offer. Work fine for home theater as well. Tight, concise sound,
Absolutely mind blowing bass! The timing and accuracy of this sub can be compared to REL Very musical but also packs a punch in a surround set up.
Is a great subwoofer looks very nice finishes great sounds excellent for the price. YouIs a great subwoofer looks very nice finishes great sounds excellent for the price. You cannot go wrong. It’s a must purchase. Thank you Mark.
These are very musical subs for audiophiles at a fraction of the price than the competition. Vera-fi customer support (Mark Schifter) is top notch. I do not believe there is any subwoofer pair in the approximately 800 dollar price range that can beat these subs for your hifi system.

Good Company… they deliver
Let me start out by saying I'm not an audiophile, just an old guy who had the chance to buy some decent speakers. I shopped around watched hours of YouTube evaluations and made my choice. These are very solid speakers that look good anywhere.
As I said, I'm not audiophile but these things blew me away with the room filling sound from a compact size. I also added the Bluetooth amps so I can put them in any room by just plugging them in.
I would recommend these to anyone looking for great sound at a great price.
Fantastic: Mark is the Boss
It took a while to get them, but it was definitely worth the wait. For the price, these were way better sounding than I was expecting. Beautiful heavy wood cabinets, excellent range, tone and quality construction. I don’t think you’d need to, but a nice addition that I purchased was the Vanguard Caldera 12 inch subwoofer. It certainly complimented the system well. I didn’t want to spend a fortune and these fit the bill perfectly.
The customer service response was outstanding and prompt. I haven’t seen this level of personal customer attention in a long time. Highly recommend.
I have mine for a week or so; I have more on order, including the Snubway. But just this one unit has made an impact for the positive, so I am hoping to build on this. It is outlet d, and depending on which outlet it is plugged into, the results can vary, depending on the outlet position in the room. I put my in the Garage by the 1st AC outlet n to the fuse box after reading on that would be a good place for one unit, and they were right, right away the TV Sound bar and the 3 subwoofers connect sounded more dynamic, and the sound was more natural and with more body, what surprised me was on the 2nd level where my Stereo is it made a positive impact there also, I went down and unplugged it and went up and listened again and there was a drop off in presence, body and weight to the music as well as lacking the detail, piano is what I used with a stand up bass, to keep it simple, all sound more real with the one unit plugged into the outlet by the fuse box, so one is staying when I get the others I will built from there and see the extra ones impact, Mark is going to send me a package that he feels will work best for my system, Mark been great even took the time to call me to answer some questions on his products and which would be best for my needs. So try different outlets, let the unit burn-in for a week or so, the only time it hurt the sound was when I put it in the outlet before the Core balanced line conditioner; those two did not play nice together at all, lost mid-bass and bass, sound was thin, but that was the only time, I will try a Snubway there when I receive it. A good product, give it a try.
Really good uplift in soundstage, tonality and dynamics! No doubt about it or placebo!
The sound feels more pure!
At around 300 hrs like clarified by mark , the effect becomes very obvious!
I will probably go one for amp and one for streamer .
Bravo!

I bought these because I have been in love with Rosewood veneer since I first saw it as an extra cost option for some $5000 speakers in the '90s. Never expected to be able to afford a pair of Rosewood veneered speakers, but then found these for under $300. I pulled the trigger, ASAP.
When they arrived, I gave them >50 hours of 85dB in room playback of the radio with them facing each other under a comforter and wired out of phase to damp down the noise. After this, I gave them a listen. Beautiful, and they sound spectacular for their price point. I felt like I won the lottery; a scratcher, not the PowerBall, but still :) I was used to a bookshelf pair w/ lite mid-bass response and slightly "crisp" highs, and these (in direct comparison) had excellent mid-bass response and are just a bit laid-back in the very highest registers to my ears. I use them with a 500-watt RMS ported 12" subwoofer crossed over at 100Hz and get good output from them with an 80-watt per channel RMS amp. Like easy, no strain, >90dB at the listening position 12' away kind of "good output". For movies, tv, and music. Plenty for me.
If you like beautiful speakers, good sound (though not detail monsters like the AMT-tweeter based speakers I have in the bedroom), and spectacular value don't be afraid to pull the trigger on these Vanguard Scouts. Just please don't expect "giant killing" sound quality for under $300, and I promise you'll be happy with your purchase.
I’ve never had good speakers to listen to music on, so this was a big leap for me. I bought the Vera link combo and the 10” caldera to go with them. Mark has answered every question of mine personally and he advised that I connect the vera-link to the high pass input and then out put with some cables to the speaker and it works like a charm! Even though I am listening to music through my bluetooth on my iPhone, it sounds absolutely amazing!!
Excellent built quality, a ported sub that sounds closer to sealed sub and for only 348 euros? Insane but true, the Caldera 12 will sound just as good in my room for music or home theater, i cant recommend this sub enough! Go dual for bombastic room filling low notes imo. The only gripe i have is the auto on off which turns the sub off after only 10 seconds, i would recommend at least 1+ minute of inactivity to turn off so lets hope they boys in the lab will sort this out on the next batches!
