Differences between Pioneer HPM 1500 and HPM 150 speakers.

[Dawid Ratal]

Hi,

I am looking for a person who had contact with the columns:
1. HPM 1500
2. HPM 150
I would like to ask having HPM 1500 (borrowed). What is the difference between these models? Do they really differ in real listening?
Have any of you had the opportunity to listen to these speakers in the same room and the same amplifier?
Have you felt any difference?
I'm currently listening on the HPM 1500, but would also like to buy the HPM 150 - because I have to give away the 1500.
I will be grateful for every answer.

All teh best!

I doubt there would be much of a difference in terms of sonic performance between them, their specs are identical except for tone controls placement:

My understanding is that they are intended to be the same. There were shipping challenges with the HPM-150 so they took the HPM-150s, broke each speaker into 2 parts to make them easier to ship and called them HPM-1500s.

I had the HPM 1500's but never heard the 150's. The highs were fatiguing but I'm sure the caps needed replaced. I was surprised how well they imaged for their size. Cool speakers for sure though!
