Help identifying a loudspeaker

jmmartins · 19th April 2009, 07:00 PM

A few days ago i listened to a pair of DIY loudspeakers that look like the attached drawing.
Can someone help me identify those? They were playing very well, I was impressed.
They were about 40” high.

Thanks

It is difficult to identify them from the drawing. They may be simple sealed boxes on a stand. But if the rear view shows a hole at the base they may be tranmission lines. Can you post a photo of them? That would be the most helpful thing to do.

Hi Jonathan

Thanks for your reply.

Unfortunately i live far away from the place where I heard them, besides I don’t know the guy, and the drawing is by memory only.
They were not sealed box. In fact I remember they had in the back a square port that was vertical (strange for me), it seems that the port (as large as the box, and firing down) was made with a piece of wood that was internal but paralleled with the back cover of the box. I remember also the guy telling me the middle range and tweeter share the same (small) inner space. And the bottom of the box was filled with sand (lowest 10”) and allocates the XO.

Visualy the main caracteristic was that the front wood panel that allocates the drivers was larger than the box itself and i don't know if this detail was for esthetical reason or other reason.
