Another piped driver speaker design.

I did my 3rd speaker design last Saturday. It is of Piping composition concept only, but this time acoustic behavior was similar to Pluto but drivers were completely different. Drivers were passive crossed over too with a simple capacitor (as it came with a Panasonic DVD player's speakers).

Because of the damping inside pipe and 180 degree horizontal sound wave direction and placing the speaker at least 3 feet away from both front and side wall, imaging was wonderful, sound clear, true to its content.
I compared it with my Tube and Cabasse set where the former one came out clearer. It does not have the heavy weight bass Cabasse brings out. It rather brings out distinct flavours, timbre sounds of individual instruments.

I believe I need to pack it more, and will be sealing it once they are properly packed. I need to steel base plates too, present baseplate is not heavy enough. It needs to be wide too.

I am happy listening it. I do not or intend to use instruments to measure sounds coming out of it as I will be listening it. My measurements are by my ear and other speakers only. These speakers are mostly made for my understanding of sound and pleasure of music only. I although feel these design is simple, effective, compact, can accommodate various drivers and can be played in rooms of various shapes and sizes. We only need to keep them 3 feet away from front and side walls while listening sound through it.

Here are some photos.

Piped driver, a 3 inch full ranger from a surround cabinet

Actually it is not a day effort if you consider mental calculations, reading, assembly processes that went through my mind, ut otherwise, it got finished in one day.
On last to last Saturday I supplied food to my gear acquisition syndrome, bought a used Panasonic 5 DVD player with 4 speaker set because I liked looks of the drivers there in.
Last Saturday I opened those surround speakers. Tried to fit them on PVC pipes.
It seemed working by physical and dimensional similarities. Gaps and mismatches seemed manageable.
Then I took one of the driver to a hardware shop, and found out that an elbow actually is holding the driver nicely. 
Bought two of those elbows and two pipe piece.
Then I took some plywood plates to a nearby wood shaping shop to get required holes in them. 
Later I placed those drivers on the elobow with MSeal.

And ran earthing wires to connect. I put some synthetic cottons inside and mass loaded them at the end too.
Here is the result.




Here is the latest version with increase in line length for more lower bass augmentation.
