I bought my first pair new at Pacific Stereo. I debated between the JBL100 and the HPM's. I bought the HPM's not knowing the differences other than the sound I was looking for.These are rock boxes and you I've put all 160 watts into them and can't break them. You will knock loose items off the walls or shelves. Glad I ended up with the HPM's. Didn't know about the rubberized cloth surround and carbon fiber cone. They still sound great after 38 years. Most other speakers would have required re-foaming them. You want tight bass and crystal clear highs these are for you. With front porting you can set them against the wall. They work great for running as a sub though your receiver from the AV sub out. I used a single RCA out into the aux in and set to mono.
