BOREA BR04 1
The new BR04 was crafted to enhance the BR03,
offering superior performance while maintaining a
compact, affordable design.
These efforts provide, upgraded performance
especially in the bass, while retaining the qualities that
made the BOREA range successful.
The BR04 integrates the EFS silk-dome tweeter and a
cellulose pulp midrange/bass driver, ensuring clear vocals
and natural warmth.
Additional improvements include a redesigned front
bass-reflex port and an expanded cabinet, optimizing
airflow for deeper, more controlled bass. The addition
of double binding posts, combined with an upgraded
crossover, enables bi-wiring and bi-amplification for
enhanced sound precision.
With a frequency range from 44 to 22,000 Hz and a
sensitivity of 90 dB, the BR04 is perfect for rooms from
10 to 40 m². It offers rich, detailed sound for both HiFi and home theater setups, ensuring a versatile and
immersive listening experience.

These are fantastic speakers, and I highly recommend them. I've had them for just over a month which has given me time to break them in, get the placement right, and to blend in my subwoofer properly. All that took some work, as it should. They sound good on their own, and AMAZING with a properly calibrated and blended-in subwoofer. I am using a 45-WPC 1977 vintage receiver with these which provides plenty of power. Yeah, I bought that from Skylabs, too!
With the BRO4s speakers, I am hearing clarity and nuances that I have never heard before - including with some music I've been listening to over the last 40 years! Notably, a baritone male voice is clear as can be with no muddling, and the report of a drumstick when the sound turned up is something to behold. They sound great at low volume, and come alive like a sports car they are producing +75 decibels with Fresh Aire or Pink Floyd. These are very open, clear, and accurate speakers.
The best part of buying the speakers was being able to go to the Skylabs store in person, and to be helped by the technicians and sales staff. I wanted to listen to the speakers again before I bought them, and Jon helped me compare them to two other speakers which were on display. One pair was about $150 more expensive than the BRO4s and the other was priced about the same. I shut my eyes and asked him to rotate between them so I could hear which sounded the best without knowing which speaker was which. He made sure to adjust the volume to compensate for efficiency differences. The Triangles were the clear winner for me, so I bought the light oak with the blue face and charcoal grilles. They look great.
Kevin has a fantastic YouTube video entitled Nobody Wants Big Speakers, and he nailed it. I wish I had seen this before I bought the speakers, but it served as a great confirmation of my choice afterwards. There is an excellent section about front and rear ports, and how to position speakers. The front-ported BRO4s are featured in this video in various places, and are specifically mentioned at the 7:11 and 12:21 timepoints.
Finally, the speakers are securely packed in a heavy cardboard double box with internal spacing which makes them very well protected. If you need these shipped to you from Skylabs (hopefully) there should be no worries about having them shipped. The pricing is about the same on these wherever they are bought.
By the way, they are not paying me for this review - this is simply my way of saying thanks to Kevin and all the guys at Skylabs for having such great products and service.
