Backstory (feel free to skip): After dabbling in headphones (Valhalla 2 + modded HD650/HD800), my previous 2-channel rig was a Schiit Yggdrasil A2 > Goldpoint SA2X> PranaFidelity Purna/Ma (NCore NC1200 module) > PranaFidelity Bhava (MTM bookshelves w/6.5” woofers).* I enjoyed this Schiit and PranaFidelity setup for a few years, but the Big Woofer bug was first planted by attending small meets of other 2-channel people around NYC (many of them SBAF members). The scale and dynamics of systems like PureAudioProject Trio15 clones, Augspurger setup (18” bass, 10” mids, Beryllium horn) and Spatial Audio X3 made me realize that while I enjoyed the beautifully tuned Bhavas, they just didn’t slap. I picked up a used HSU Research sealed 15” sub, and while I had issues integrating it with the Bhavas, I enjoyed the physicality that the subwoofer was giving me in the bottom octaves. I would have loved if this weight and tactility extended throughout the frequency range. In the spring of 2020, a few big changes to my living situation (newborn in the apartment and COVID lockdown) made me look at the current state of headphones again. I ended up getting open-box Focal Utopias and a used ECP Audio DSHA3F. I was floored by a lot of what this combination did. Resolving power, transient speed, dynamics, bass quality, and more. I just needed to rein it in with some light EQ and a Rockna Wavelight to really match my preferences. My headphone rig was so good I wasn’t listening to my speakers as much, so I decided to try to replicate what I was hearing through the Utopias with a new 2-channel rig. I wanted a speaker setup that dug more into the recordings. I’d been casually reading about Troels Gravesen’s new designs over the years, and became especially interested when he posted about his reasonably affordable Faital 3WC (12” bass, 6” mid, Beryllium tweeter option) design and, later, the 3WC-15 (15” bass, 8” mid, Be tweeter option). On paper, this looked like exactly what I wanted to get my 2-channel rig closer to my Utopia headphone experience. 96dB efficient, 15” and 8” woofers for proper bass and mids, a Beryllium tweeter, and a crossover that wasn’t overly complicated. I’d be putting it in the quite small room that I work in (11’x9’) and was worried about a few things like it being too big for the room, not being able to get far enough back for all the drivers to properly sum and, the biggest thing, not having heard the design before before (let alone any of Troels’ others). I’d been liking the recent things Troels had been writing when it came to speaker design, so I decided to just go for it and bought the crossover kit he sells for the 3WC-15. I commissioned a local woodworker that seemed to really know his shit when it came to loudspeakers (having designed some of his own from scratch) to build them. He built them with Baltic Birch and painted them in a beautiful medium black that I’m quite happy with. They were delivered almost 2 weeks ago, and two things immediately popped out at me when I hooked them up to two Aegirs. Holy shit, they’re crazy dynamic/intense, but thank God they work with my room. I might be wrong, but I have a feeling these large cabinets react even less to the room and where they’re placed in it compared to my old bookshelves. That was a surprising little plus, but I wanted to solve this issue of unrelenting energy. I bought a Radial J-ISO 1:1 transformer to see what the speakers would sound like with a single Aegir, and it helped calm the speakers down. Transients were more rounded rounded, the speakers seemed less hyper, a bit sweeter, but the single Aegir seemed to have little in the way of grip on the 15” woofers. For shits and giggles, I plugged in the speakers to my PranFidelity class D amp and immediately thought I was listening to my Bhava bookshelves, only a larger version of them. There was a kind of laidback gloss over them, and it made me realize that the speakers might just be good at reflecting whatever I put upstream of them. I missed the sheer technicalities of dual Aegirs, so I plugged them back in, decided to play around with speaker positioning some more, and moved them closer to the front wall away from me. This, plus a gentle EQ lowering high frequencies (plus hours and hours of burn-in, I’m sure), seems to have done it. It feels like the speaker version of my DSHA3F and Utopias. My chain: Rockna Wavelight > Dual Aegir > 3WC-15 What I like: The immediacy and physicality of an efficient big woofer design. Rimshots and handclaps slap. Kicks knock. The speaker feels alive, and I can better distinguish and imagine the specific materials of each instrument. Not only is the bass fast, but mids seem to be really fast as well. I wonder how much the mids are helped by the supporting low end. Sense of scale. Everything sounds bigger on these than with my old bookshelves. Crowds seem more like crowds, upright bass and cellos seem properly sized on the soundstage. If the Wavelight has ever been criticized of not being as textured as some other DACs, these speakers make up for it. I knew they were what I was looking for on day one, but it seems to be getting more refined/nuanced with play time. What can go either way: Dual Aegirs and 3WC-15 don’t seem to intrinsically sugar-coat anything like my PranaFidelity setup did, so great recordings and mixes sound really really great, shit recordings/mixes sound quite bad. I don’t think the speaker is designed to homogenize all music into something easy and agreeable, so you’ll have to tune to your liking with DAC/preamp/amp. Edit 02/08/2021 - After about 15 straight days of play-time, they seem to have developed a smooth delicateness that shines through when the music calls for it. This hyper character trait that was fatiguing, in the beginning, seems to be gone. What I don’t like: This is kind of minor in the grand scheme of things, but while bass quality is really great, I’ve heard harder punch/impact before. I’m not sure how much of it is that the woofers are also at home in open-baffle designs and aren’t meant for thunder, and how much of it is that I’m not throwing dump trucks of watts at them. Like the Beryllium drivers in my Utopias, they require a light touch of EQ to get it in the pocket. I’m using digital EQ (in Roon) for now but might put a resistor behind the tweeter to do it the old-fashioned way. While it might be a little annoying to have to adjust for this in both my setups, I think the trade-off of improved technicalities compared to more traditional driver materials is totally worth it. I’m a big fan of the material when implemented properly. Focal speakers do not do this right, IMO. Edit 02/08/2021 - After more burn-in, preferred amount of EQ has gone from -3dB to -1dB. I feel that treble has relaxed and smoothed out over time. The heat that two Aegirs will be radiating come summer. I have to walk into my room sideways and have to be careful opening the door to not bang into the left speaker cabinet. What surprised me: Imaging precision. I’d read that larger front baffles don’t image as precisely, but I think the Aegir and 3WC-15 combo might image even better than my previous setup. After some comparisons this week, I think a lot of it is the class D amp’s fault. My bookshelves with 6.5” woofers measure down to about 40hz, and so do the 3WC-15s with 15s. The quality of 40hz is completely different, though. I can hear transients and textures down there, now. Kick drums aren’t mushy anymore. Things to note: Don’t position the speakers in a near-field configuration. The speakers need some distance to breathe or else the wall of sound will pummel you. For a few days I was looking for used EAR amps and preamps wondering what kind of sweeteners I’d need to dial in the sound to my liking. Drivers seem to become truly cohesive at about 6”. If my room was any smaller, I might not have been able to listen 6ft away. When I asked Troels about distance to integration, he respond in an email that he’s had good moments from as little as 2 meters distance (6.5”). I’ve reconnected my budget subwoofer to fill in the foundational bottom octave for the bass I can feel, while letting the 3WC-15 handle the musical section of it. It seems much easier to integrate than with my bookshelves. All in all, I am impressed with this larger speaker design from Troels and would definitely recommend it to others that are curious. With the way speaker pricing can be in the HiFi ORFAS industry, I think this could be one of the more affordable ways to get this level of sound reproduction. Even more affordable if you can build it yourself and don’t need to hire someone like I did. *Before that, I’d had Adam Audio A7X’s before moving into the passive speaker world. I had Philharmonic BMRs powered by a Van Alstine amp, but I’d rather not talk about that.
