Glad there is at least one other speakerbuilder on here whose audio system is bigger than their video!
Thanks, it is my favorite winter time hobby.
I have made well over 50 different speakers...although I have to admit most of them have been subs of one sort or another. I even made a bluetooth speaker for my cousin for Christmas one year (we give homemade gifts). It cost me under $30 in materials and would blow any other bluetooth speaker out of the water. It actually had real bass!
Anyways, here is a shot of that bluetooth speaker as well as a better shot of the line arrays before they got stuffed in the man-cave.
Is the PVC pipe for looks or does it serve a purpose? I noticed you have PVC pipes in your living room speakers as well.
The PVC for the large subs in my listening room serves as tuned vents for the enclosure. Those are basically down firing "ported" enclosures. There is a balance between the volume of the enclosure, the diameter and number of vents, as well as the length. The vents serve to extend the low frequency capabilities of the speaker at the expense of faster roll-off below the tuning frequency.
The PVC for the BT project was the actual enclosure itself. It served as the speaker cabinet. You can see there is actually a port built into the cap in the bottom. Again, the diameter and length were carefully selected to best enhance the low end of the speakers in that enclosure.
It is a fun hobby, and CAN be pretty in-expensive if you keep it sane. Speaker enclosures can be made from most anything, and most of the software to aid in the design is free! Partsexpress.com is a great place to go for decent drivers at low prices to play with.
