Home concert theater speakers
The design was based on the curved speaker arrays used for live concerts. I wanted to make them modular so I could add them in pairs if I needed to. The only thing that would change is the port size and length. And of course the wiring.
I chose the hi-vi f5 drivers for this build. Part # 297-435.
Dayton Audio DC28FT-8 1-1/8″ Silk Dome Truncated Tweeter Part # 275-076
The enclose is designed to change the angle of 5 degrees from one speaker face to the next. Creating a curve and essentially adding more of a sweet spot whether sitting or standind.
The assembly is pretty straight forward. There is no top or bottom to the modular units. It is 3/4″ particle board. A cutting template was made to insure some consistency. After the units were assembled and glued they were assembled to each other. A top and the bottom port was attached.

Zobel network was also used.
1.5 mh inductee was also used to bring down the spike in the mid/bass frequency around 1200 hz.
Tips & Tricks:
To insure 8 ohms the speakers have to be wired 2 sets in parallel and those two parallel sets in series.
I’m very impressed with the clarity and the overall punch these have added to my system. They are the “B” speakers. I bought L-pads to control the volume of the tweeters but used them to control the volume of the mid/bass drivers instead. They are very loud.
About the Designer:
I’ve been building speakers (and hydroplanes) for more than 40 years. I love good clean immersive sound. A machinist by trade.
