Project Description:
My new 192 Watt DIY DML panel build (Bertha)! At 20in x 22in each 1/4″ thick plexiglass panel is running at 4 ohm’s @ 96 Watts, exciters wired in a series-parallel configuration for each panel and powered by a HiFi 100W x 2 (200W) Bluetooth 5 amp with a 24V 10a power supply. A total of 8 Dayton Audio DAEX25FHE-4 Framed High Efficiency 25mm Exciters each 24W 4 Ohm were used for this DML build.
Design Goals:
My design goals were to create a powerful and loud HiFi system from a pair of DML panels made of 1/4″ thick plexiglass.
Driver Selection:
Part# 295-224
Enclosure Design:
Plexiglass
Enclosure Assembly:
Plexiglass
Crossover Design:
none
Tips & Tricks:
Providing the full power of a 24V 10a (240V total) power supply to a 200W HiFi amp with treble and bass regulation really took this project to the next level, along with placement of the exciters on the proper panel material. I found this great resource from Dayton Audio’s site that helped me with this particular build here: https://www.daytonaudio.com/topic/excitersbuyerguide#installation
Conclusion:
Using multiple exciters configured and powered correctly on thick plexiglass produces unbelievably beautiful sound imaging- The best DML speakers I’ve ever heard for my third and most powerful DML panel build- Bertha!
