I recently purchased a set of mids and tweeters for a pair of HPM-900's to try as an upgrade I'm my HPM-100's but realised that the tweeter holes do not line up but fortunately the mids do.
I have just swapped the mids over wich to my ears is a notable improvement due to the carbon graphite cone meterial instead of paper.
Has anybody else had any experience with this upgrade? I'm thinking perhaps I could drill new holes in the cabs to make the tweeters fit but I'm still in two minds about this.
I also have a pair of HPM-150 speakers and the mids and tweeters match up better cosmetically with the 150's but HPM-150's are so rare here in the uk perhaps I should just keep them original, I don't want to devalue my speakers incase I ever get round to selling them. I will try the mids in the 150's next to see how they sound and If they are an improvement then they will probly stay there but its just a shame to have the tweeters sitting around not being used
