Repair or Replace my JM Labs Micron Carats

If your looking for more bass or fuller sounding speakers, you might as well fix the woofer, and get a subwoofer. That's what a lot of people with bookshelf speakers do. I am personally not a great advocate of subwoofers, thus I leave it to others who use them to guide you.
The best and most legit way to select a different speaker is to audition them. If your local store has these choices in stock, why not try them? I might have misunderstood your post.

Thanks Mechans. He typically carries higher end components and wouldn't have most of those in stock. Last time I was in the store to buy the DAC I only saw a couple of bookshelf speakers on display (I don't know what).

Before going to audition what he does have, I was looking for guidance on which of those might be ones that I should ask him to also bring in so that I could audition them.

Sorry for not being more clear to begin with.

I used to build speakers in the 90s using focal, seas, audax, etc... I remember the focal as being dry sounding, not much upper-bass when compared to seas drivers in the same box.
Therefore, my vote would go for the psb...
or maybe someone like zalytron can get you the driver for far less than $200.
I would definetely keep the boxes, keep the tweeters, and have zalytron design a nice x-over with new woofers... worth checking into it imho; you could update your micron with a super kit for less money than if you would buy a new pair.

Thanks Chrisr. I hadn't thought about going the modify route but that's an excellent suggestion. I'll send zylatron an email. My only concern there would be not being able to audition.
Based on what I've been reading in my review search, I'm also going to add the Focal Chorus 807V to the list of considerations although it will mean I have to travel a bit to find them; unless my dealer decides he wants to get them for me as he doesn't normally carry Focal.

Now I had a whole other idea - fix the one woofer and buy a new Arcam FMJ P38 Amp that I can connect to the Creek to give me a much more powerful amp which might draw better performance out of the Micron Carats and also afford more options for speakers in the future.

What do you all think of this idea?
