Years ago, I was inspired by the look of the Focal Grand Utopia speakers. I wanted to make my own and had a plan to build a 3 box, 3 driver version. I soon found out that I couldn’t cover the low end properly with one driver and so the design became 4 boxes. The plan was one box each year and I nearly hit it but finalizing the crossover design took a lot of time. In that time, I noticed an area in the mids that needed some reinforcing, so I added the 8” driver in its own sealed chamber. The 15” driver is powered by its own class D amp which is why I show the crossover with and without it connected. In the last 2 months I made a big push to finalize them and 7 years after I started them, they are finally finished.
How do they sound? Incredible. Unless I’m standing 3 feet in front of one of the speakers they sonically disappear and stereo image up there with the best of them. I finally got them in the listening room and now it’s time for some music and something else…
The pictures were not taken in the listening room I just needed some sun light.

Hello, I am the legal counsel for Focal, could you please PM me regarding trade dress infringement?
Ha ha just kidding, though feel free to send me money! It looks really amazing! I think I will blow up those picture to show my wife, and scare the hell out of her, so she won't complain about my towers.
Very nice, but a question:
Were the near field measuremennts the basis of your developement of the crossover?
Kind regards
Michael

Impressive result.
One question...... What do you use to drive these?
Must be kind of a stable amplifier, considered the impedance reaches down to around 2 ohms at 100 Hz??
Again, congrats with an impressive build

....after virtual baffle step compensation.thats the whole point of a nearfield acoustic test
