Listening devices to check out the tweeters

I've been using PVC pipes of various lengths to check out the tweeters high on the nesting planks. This is a commonly used method by many I presume.













Recently I was checking some wiring up on a ladder close to the tweeters and I find a rigid tube (the short one pictured above) rather cumbersome. Then came the idea in a bathroom - using the shower hose; not exactly an "Eureka" discovery an idea but one that is pretty neat. I took it down and attached a cut-off cone section of a milk bottle at the other end - there you see below. Still a little cumbersome in use up on a ladder, but much preferred.













Then the other day I happened to walk past this forgotten toy left on a bench and can't resist to take a photo of it. Hmmm... seem like a better tool only if the connecting tube is longer.













Too bad it is not mine, so I can't check it out! Any doctors out there has a spare one?
