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

"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.
Caldera 10 Duo paired with Magnat monitor supreme. They blend well, have great audio quality, nice looking & hefty build. My system sounds beautiful. I have the calderas set just over 1/4 volume and the bass is vibrating the gutters on my house.
I guess I happened to order as everyone else realized the bang for your buck deal Vera-fi is offering here. I had to try and be patient and wait for the backorder to be fulfilled. As I waited I recieved excellent communication from Mark and his crew.
I wouldnt hesitate to refer a friend.
Im super happy 🤘😁🤘
Thanks Vera-fi !!!
When I added the LNBH and SSZ to my system, I installed them together, so it’s impossible for me to separate their individual contributions. After a long run-in period, the changes became so compelling that I found myself staying up late, revisiting every song I’ve ever loved.
One of the most striking improvements was the disappearance of noise-related limitations. With these two in place, details that were previously buried in the mix became clearly audible. I could hear the subtle sounds of a vocalist taking a breath or even swallowing, which added an incredible sense of realism to the performance.
The overall imaging feels more precise, with every element in the soundstage locked in place. Music flows effortlessly, and the presentation is so engaging that it’s hard to step away from the listening chair. This pairing improved the technical side of my system while also bringing a level of musical connection that keeps me listening for hours.
I recently replaced the stock fuses in both my SSZ and Tempus PSU with the Graphene Sluggo.
Even at the start there was a sense that something had shifted, but this is not the kind of upgrade that shows everything in the first hour. In my case it really came into its own after about 300 hours. The first 50 hours the treble had a slightly tighter character and the mid-bass felt restrained. Around 150 hours the presentation started to relax, with better flow and more natural layering. By 300 hours dynamics felt settled, micro-details became more apparent, and the whole system sounded more connected.
What stood out most to me was the neutrality and transparency. It does not push the tonal balance in any direction, it simply lets the system speak for itself. Highs extend cleanly without harshness, keeping fine texture and air. The midrange has a natural presence with good retrieval of subtle detail. Bass is well controlled, evenly weighted, and separated with clarity.
On the SSZ, highs became smoother while keeping resolution, and the soundstage felt more open in both width and depth. Vocals gained more dimensionality compared to the stock fuse. On the Tempus PSU, tonal balance stayed consistent, but resolution improved across the range, making instrument separation easier to follow.
Mark at Vera-Fi has been great to talk to. Every question I asked was answered with detail and warmth, which made the whole experience more positive.
After this I plan to gradually replace all the fuses in my system with the Graphene Sluggo. For anyone using SSZ or Tempus PSU who wants more resolution and detail without altering the system character, this could be worth considering.
