Project Cost:
$100 – $500

Project Description:
I started with a vibrant 12×24″ metal print of fireworks over the Madison, Wis. city skyline — the “Shake the Lake” show over Lake Monona. This is my own photo, in a high-resolution professional print directly on a sheet of polished aluminum with1.5″ inset metal frame on the back. I installed a Dayton audio 15w/ch amp and 2 Dayton exciters behind the panel. Power switch, volume control, and aux audio input mounted discreetly on the side.

Design Goals:
I wanted to conceal a stereo inside a piece of art. As a photographer and speaker builder, this is the convergence of my two hobbies!

Driver Selection:
Dayton Audio DAEX32EP-4 Thruster 32mm Exciter 40W 4 Ohm Model: DAEX32EP-4|Part # 295-230

Enclosure Design:
The Exciters are mounted directly to the back of the flat aluminum panel

Enclosure Assembly:
Exciters, amp bracket, and all wires glued or taped to the backside of the panel, concealed by the inset metal frame.

Crossover Design:

Tips & Tricks:
Start with a really good photograph that people want to hang on the wall.

This is more of a conversation piece than anything else. It’s a great photo with a party trick hidden inside.

      Bobby: the midrange is nice and clear, but the high highs in the low low’s are muted. But what can you expect from a sheet of aluminum with two transducers glued to the back?? Sound is surprisingly good for what it is. Certainly not an audiophile solution. More of a party trick, conversation starter, etc.
