Vandersteen Question

The really strong and ambitious can also spin those fives around and bounce everything off that rear wall !!!!! Don’t try that after a libation or three!!!

have fun

And what is super cool is that in addition to everything Johnny said above - there are some dry studio and even live recordings where ambieint / spatial information is deficient / missing that the added cost of the rear tweeter ( which is not peanuts $$ ) is very justified.
since it’s there. A wise audiophile would take that opportunity to discern differences and experiment, just as all the posters / owners are doing :-)))
