Hi, guys! Recently, I purchased a pair of speakers from Treehaus Audiolab, and I couldn’t be happier since. I’d like to share my experience with them because I really think they deserve attention from us!
When I first visited Treehaus’ showroom in CT, my plan was to check out their 300B amp—maybe their preamp too—but definitely not their speakers. Open baffles have never been my thing. Rich, the founder of Treehaus, was incredibly nice (as I’ve mentioned before). He set up an entire system with three sources—two DACs and a vinyl rig—for me to enjoy. It was an amazing afternoon, and I was already impressed with the amp and preamp just by seeing the design, materials, and craftsmanship in person.
But once the music started playing, I realized the speakers were something special. The sound was organic, relaxing, and completely immersive. The midrange was thick and full, making vocals and instruments feel dense, lifelike, and captivating. Normally, I don’t go for open baffles because they tend to sound clean and spacious, which is great, but often lack that “pop” in the vocals. These were different. Vocals and instruments stood out while still feeling expansive, intimate, emotional, and realistic.
I’d been searching for the right speakers for over a year. I love horns, but the ones I wanted were $80k and up—out of reach. The more affordable horn options had their strengths but always felt like compromises. Traditional options, like YG Acoustics, also impressed me, but a pair of Haileys costs $60k+ and requires a high-power amp—another huge expense. What I really wanted was a pair of speakers that a SET amp could drive beautifully, with balanced sound, emotional engagement, clarity, and a budget around $20k. Hearing the Treehaus speakers for the first time felt like I finally found what I was looking for.
After looking into the open baffle design, I kind of understood why I liked them so much. They use a pair of field-coil drivers (very cool ones) as the main drivers, covering everything from around 100Hz to over 10kHz. Above that, a pair of Fostex tweeters handles the upper range, while a pair of subwoofers with miniDSP takes care of the bass. This setup (I am just guessing here) brings some characteristics of full-range single-driver speakers (my previous speakers were Cube Audio F8 Neo, full-range single-driver): the imaging and tonality are very coherent—maybe thanks to the field-coil drivers covering so much of the range?! At the same time, the subwoofers and tweeters perfectly complement the lower and upper ends, making the sound balanced and well-rounded. This really extends the speakers’ versatility for different types of music. Also worth to mention that we swapped DACs (two are in similar level) just for fun, and in most unfamiliar systems, this kind of change usually doesn’t leave a huge impression to me. But here, the difference was clear and straightforward, showing just how revealing the speakers were. I indeed had concerns that these vintage style drivers are not revealing, but no, they are golden.
Another thing I really appreciate is how adjustable the speakers are. With the tweeters, miniDSP, and the voltage of the field-coil drivers, it’s easy to tweak them to fit different systems, amps, tubes, and preferences. I’ve even driven them with a budget Elekit 8800 tube amp (with EL34), and they still sounded amazing! Better amps and preamps bring out even more, but the speakers don’t fall apart with more modest gear. They deliver great dynamics, full bass, and a balanced sound on the first day it arrives.
If you’re someone who loves SET amps and is working with a similar budget, really recommend you to give these speakers a try! Visit Rich’s showroom—I’m confident you won’t regret the trip.
Lastly, the build quality deserves a mention too. Rich does an incredible job with the woodwork. He’s meticulous about details, and when you work with him, you’ll see how much he cares. You can customize almost everything—wood panel style, shape, size, finish, color—you name it. My wife even said, “If you can get ones that look like RH furniture, I’ll be happy to have them in the living room.” Rich made it happen, lol.
I am going to borrow Rich's pictures again for my speakers:
