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.
There are a couple of qualities of these subwoofers that I would like to comment on favorably. First, the coverage of the midbass frequencies, and in fact the musicality of the subwoofers, is remarkable for the price. In my room, the frequencies between 65 and 125 are suppressed by the room. The Caldara subwoofers compensate for this very nicely. Second, the visual appearance of the units is very nice.
Wow, I miss the ultra low frequencies that my old but no longer functional REL subwoofers provided, my music room does not really allow for reproduction of the frequencies between 20 and 40 Hz. The trade-off of musicality is therefore significant compensation.
I appreciated Mark’s generous offer to substitute the Caldera for the smaller model which was out of stock. If I can make one suggestion for future Caldera models, it would be to have speaker level inputs in addition to the RCA inputs.
Wonderful purchase. My system sounds great.
Wow - I honestly wasn't sure if I was even a "bass guy" before purchasing 2x Caldera 12"s, and my Wharfedale Linton's even had already solid bass response, but in the endless quest for the "wow" factor, I was pointed towards Vera-Fi's subwoofer offerings.
Let me just say, I am absolutely blown away. I can't stop listening to my system -- it just sounds too good. I also have not experienced such remarkably good customer service from a company in quite some time. Thank you to Mark and the team for making such a reasonably priced product that punches far into much higher price points.
Is very good. Excelent.

A pair of them easily surpassed the much more expensive sub, and with relative ease

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!!

"First, I'd like to thank **Mr. Ace**. He was a great help with the delivery.
The **SnubWay - Noise Defender** has enhanced the audio system. A new level of sophistication has been added to the system, which was previously a straightforward 'Main Stream' setup.
Firstly, I feel like the **soundstage is wider**.
And I feel like it has captured the **subtle vibrations and noise**.
Frankly, I had been briefly tempted by Chinese-made products due to their price advantage.
However, **vera-fi-audiollc** clearly demonstrated the **technical gap** between those products and this one.
Thank you."
This is my first Hi-fi set of speakers I have ever bought. Before this, I listened to BOSE speakers.
WOW.... what an upgrade these Vanguard scout speakers are!!
I had to wait a couple months to get my order (because of tariffs), but Mark and his team were really amazing at answering all of my questions and updating me with the progress of my order.
I ordered the Caldera 10 sub, vera-link amps, and the scouts and Mark helped me to understand how to plug the vera-links bluetooth amps into the subwoofer through the high-pass input and output through the high-pass directly to the right scout speaker and it works like a charm! I couldn't be happier!
You will see two pics in my review of the back of the right vanguard scout speaker, because I wanted to show you that if you have to peel the velcro off of your speaker and place it elsewhere, it doesn't leave any residue to clean up! It's not a huge deal, but it certainly made my life easier.
I am a fan for life and will be ordering some of the new things they are working on in the future!
I purchased three Caldera 10's to go with my three pairs of Scouts. I love them, so I purchased 4 more to get small rooms 2.1 & large rooms a 2.2. I love speaker systems but I haven't had a good set up for years. I looked into this for months. I didn't know what my sound system was missing till I got the lower end filled in.
Great speakers, right in my budget. I purchased one pair, broke them in, loved them, and then purchased 2 more pairs. I had the option of ceiling speakers but bookshelf sound so much better. The Scouts allowed me to get great sound and budget. I have them in several rooms now. 2.2 in the main rooms and 2.1 in the small rooms. When connecting a Caldera 10 it was suggested to put a HPF 70h on the Scouts. I haven’t been able to find a good low cost 70h, closest so far is 80h $25. I purchased (3) pairs of Scouts and (7) Caldera 10. So HPF is important to focus more on the mid and high’s. Really really like Vera-Fi Scouts and Caldera’s!!!
Great product , great prices and good follow up when required.
Good price, looks great, well made -suits the scouts perfectly
I had my eyes on a Caldera 10 subwoofer for quite a while before I decided to take the plunge, but I'm really glad that I did. I initially had reservations for how low the price was for what it claimed it could do, but eventually a sale came along that was a little too good to resist and I purchased it for $149.
I imagine myself and quite a few other people ended up ordering around this time and it took some time before my order was fulfilled. Additionally, there were significant delays in shipments due in part to ongoing changes to US import policies, but Vera-Fi diligently kept me updated throughout the process, even responding to my emails I sent with questions. In hindsight, I am glad I was patient and waited to receive mine.
Though it took some time, in the end, I received a cute little compact subwoofer to pair with my budget living room setup and have been very pleased with how musical and quick it is, as well as how much it filled out and enriched the music for a pair of smaller bookshelf speakers. I don't think there is a better budget sub for a 2.1 stereo setup for this price. The Caldera 10 is a product that knows what it is and does it damn well.
Highly Recommended.
