Plumbing the Depths of Subterranean Bass with Vera-Fi Audio's Vanguard Caldera 12 Subwoofers


Early this year, I flim-flammed Vera-Fi Audio main man Mark Schifter into sending me one of his new Vanguard Caldera 10 subwoofers. I was desperately in need of ultra-low bass following the untimely demise of my beloved REL T9, which had been a true and faithful servant for a dozen years. I honestly had no... Read More »

A Follow-up on the Vanguard Caldera 10 Subwoofer: Dual Subs Now Equals Double the Fun!


My original review of the Vanguard Caldera 10 subwoofer earlier this year was nothing short of an all out rave, and deservedly so! I know this is beginning to sound like the proverbial broken record, but how Vera-Fi Audio's Mark Schifter and his partner Viet Nguyen can design and manufacture a superb unit like this...

Vera-Fi Audio's Vanguard Caldera 10 Subwoofer


Back in 1984, before all the cool old independent hi-fi shops started vanishing into oblivion, there was a nice older dealer in northwest Atlanta called High Fidelity SSS. The shop had McIntosh amps, JBL Hartsfields, and all kinds of vintage gear scattered about, along with one room that was stocked with more modern gear. The... Read More »

Definition from Oxford Languages coup de main /ˌko͞o də ˈman/ noun: a military attack that relies on surprise, speed, and concentrated strength to attain its objectives. Introduction There are brands that many consider the very foundation of the high end industry. In my opinion, REL is one of those brands. They have a long and impressive... Read More »


SVS SB-3000 Subwoofer Follow-up


Back in July 2019, after completing the original review of the SVS SB-3000 subwoofer (HERE), I took the subs out of my system. It took just minutes to determine there was no way I was going to send them back to the SVS folks in Ohio. They transformed my system into something special, and I... Read More »

The SVS SB-3000 Subwoofer


It seems like every conversation I've had with audiophiles about subwoofers the last few years included 3 letters: SVS. No doubt subs from this company were gaining some real respect among the high end community. When I met Nick Brown (VP Marketing) and Dan Marks and (VP Operations) from SVS at AXPONA 2019, they were... Read More »


A Simple Subwoofer Setup: Get Rid of the Guessing and Bring in the Music


Happy Little Accidents Bob Ross (1942-1995) was the loving host of the 1980's TV show The Joy of Painting. He enjoyed the peace, serenity, and most importantly; the process of creating a beautiful painting on a blank canvas. Many of our listening spaces are blank canvasses. But, despite the usual claims that great low-frequency reproduction... Read More »


SVS SB-4000 Subwoofer


Time was (and largely still is) when the use of subwoofers in a two channel, high end audio system was considered at the very least controversial, and heresy to the more vehement opponents of the idea. Having subscribed to this purist view myself, I didn't bother much with them over the years and as a... Read More »

SVS SB16-Ultra Subwoofer


You know the phrase "size matters", I'm sure you've heard it before. Does it matter with a speaker? If you're attempting to reproduce low frequencies, you bet it does. Most of the time I've had subwoofers not larger than 10". I was always under the impression that if you go too large, that you would... Read More »


The GoldenEar Technology SuperSub XXL Subwoofer


Over the last twenty-five years of system building, external subwoofers have never been part of the equation for me. Despite my love of deep bass, my love for the seamless continuity between drivers has always won out over the prospect of deep but poorly integrated bass. Bolstering this attitude has been the several systems I... Read More »


SVS SB-2000 Subwoofer


I value ground trembling sensation of well-executed extreme low frequency as much as any audio nut. For the majority of my listening, though, extreme low frequency is not essential to musical satisfaction. However, lately I have developed a latent appreciation for electronic dance/ambient influenced music. Needless to say, my KEF LS50 speakers, overachievers that they... Read More »
