"""The Pioneer HPM-100s were built by former JBL engineers to do one thing, and that was to be a better sounding speaker than the JBL L100. I think they admirably did their job, as the HPM 100s are one of the best sounding speakers ever built. I know this is saying a lot, but this is the general consensus among many people in the Hi-Fi Industry. These speakers have just the right balance and warm tones. These are amazing sounding speakers.
These particular Pioneers work 100% and sound remarkable! The depth of the sound of these speakers is incredible. Breathtaking sounding speakers."""
