Overpriced and overrated speaker. I’ve had the 100W and 200W version simultaneously. I completely dismantled both to compare the drivers, crossovers, and cabinets. There’s absolutely no difference. I read somewhere that the reason Pioneer came out with the 200W version was because they felt the low 100W rating was hurting sales. I’m convinced that’s why because everything is identical in both models. Even the crossover component values. So don’t pay the premium for a 200W version just so that the terminal can read “200W” and to get the silver port ring. I hooked up both models to my 450W per channel pro amp just to test spl output and they both handled all the power. Although I would expect a higher sensitivity rating for a 12” 4-way speaker, the HPM-100 can surely play at ear splitting levels. I had a pair hitting 126dB at my 12’ listening distance. When testing for sound quality I used my Sony CDP-CE335 via toslink to my Yamaha DSP-A3090 in order to utilize the Yamaha’s superior DAC. At first listen the speakers sound good but after a while they sound fatiguing. Not surprised due to the 4-way not vertically aligned drivers. That means 3 crossover points where frequencies can overlap. I also expected the bass to sound deeper because they supposedly extend down to 25Hz. No way. My Klipsch KG3.5 with a single 8” woofer had much better quality bass. I didn’t say more bass. I said better quality bass. The HPM-100 are definitely not audiophile quality speakers. They are rock music speakers or party speakers. Many owners try re-capping them but if you look at the crossover points they’re just wrong for sound quality. Everything is set too high. Bart Locanthi should have just designed it as a 3-way. Sometimes less is more especially in audio. The only decent thing about the HPM-100 is the woofer and maybe the cabinets although the wood veneer is super thin so be careful if you plan on sanding them down to refinish them. I did it but it was so much work that in the end it wasn’t worth the labor I put in. I ended up selling them. After owning the 100s, the 60s and the 40s I now know what they’re really worth. I can’t believe how much people pay for them. Other speaker brands I’ve owned are Klipsch, ADS, MB Quart, Magnepan, Dynaudio, Boston Acoustics, Tannoy, Realistic, Technics, Sony, JBL, Dynaco, Ramsa, EPI, and Cerwin Vega. I’ve installed commercial and residential systems for over 20 years.

Very good sounding speakers....pretty blown away.
I am about to modify them a little bit though, to make them into a 10 rating. I'm going to take the tweeters from the Pioneer S910's and Mids from the HPM 900 and switch them out. Of course i'll be keeping the originals stored away.

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.

Pay less for the 100W version and get the exact same speaker.
