Hello,
After having been a rather silent reader or only built speakers, now I would like to try my hand at a small project. I have built myself and share the progress with you guys, I would be very happy to receive feedback and help welcome
The adenture to build a new loudspeaker began with a clear targets:
1. Based on SMJ's Modula design for the MW19P and DA25TX, the cabinet was redesigned into a rectangular box, primarily to reduce the speaker's depth to better fit my family's living room.
2. I've always felt the front panel of the DA25TX is flimsy and not very sturdy, so I plan to modify it. The goal is to reduce the diameter while maintaining the front panel shape; and increase the thickness of the screw mounting area.
3. Creating a rigid, resonance-free cabinet that would let the drivers perform at their best. The initial concept centered on using Phenonlic for the enclosure walls, chosen specifically for its exceptional stiffness and inherent damping properties to significantly reduce unwanted cabinet vibrations and coloration.
Inside the enclosure, an elaborate network of strategically placed internal partitions and braces was designed to improve the dynamic performance while maintaining proper volume for the bass alignment.
Below are pictures of the speaker cabinet design. One detail not shown in the drawing is the placement of the port. Since my living room isn't ideal, it's small. To solve that problem, I need to reduce the distance between the speakers and the back wall while still having good bass. So my idea for the speaker enclosure is a reflex type with the port located at the bottom.
I admit that I referenced the idea from the Purifi SPK16 DIY Kits. The drawings were created for a local CNC service provider to execute. The phenolic panels have been purchased; I will update the progress in the next few days.
