My prototype pipes always lacked a certain tonal depth. In the past, I laid that down by the fact that I was using 2" pipes (have a look).
The drivers I was using to that time came from a TV set. While this drivers taught me a lot and enabled some experimenting, which lead to the latter 3" design, which sits in my living room, now in a folded manner.
Strangely, the 3" drivers seem not to be of that much better quality... however, the 3" setup a much butter punch in all aspects.
Willing to further experiment with the PVC prototypes, I ordered a pair of 2" 3W drivers, similar to those.
Yep, those cost next to nothing. They sound surprisingly good when driving my folded "XXL PVC" prototypes.
The question remains if it would be worth to further fold the pipes for improved portability.
