This is a hybrid design of the PLUTO loudspeaker. This an experimental design using a passive crossover with some design features of the Pluto. This is not intended to be a Pluto clone.
To minimize speaker box resonance. To preserve the “point source” feature of the Pluto design. To design a passive crossover using Jeff Bagby’s “Passive Crossover Designer”.

Closed box (tube) stuffed pipe design to minimize speaker box resonance. The unique feature of this design is the woofer is placed at a 45 degree angle. To my ears, the woofer integrates better with the tweeter compared to an upward firing woofer. My woodworking skills are at a beginner level, so I wanted to keep the enclosure design simple.
I wanted a second order Linkwitz-Riley design. After experimenting, I ended up with something close to a second order design for 7 ohms at 1400 hz.
Tips & Tricks:
After a little experience is gained; trust you ears before any graphs or theories.
I am really pleased with this project. Both speaker drivers sound better than I expected. The “point source” aspect of the design gives these speakers an imaging quality that is not in a regular box design. Minimizing speaker box resonance gives a cleaner sound to the speakers. I play these with a subwoofer which fills out the bass. When listening to the radio, they are fine without the sub. I would recommend this to anyone wanting to experiment with speaker designs. I would be very interested if someone with more experience and a better ear made improvements to this design. With less than $60.00 for speakers and an economy crossover; this is a low cost, high value design.
About the Designer:
I am retired and enjoy experimenting. I enjoy reading and researching in the diy community. I am at the beginner level of speaker building and feel ready to bring some projects to completion.
