Logic 7 Question

Skylinemotorsports · 09-18-2018, 03:33 PM

I am trading out my hifi system and bought 2 logic 7 speakers off ebay. I did not notice but these appear to be the front, not the rear speakers, as the magnets are tiny compared to the others.

Is there going to be a big difference in sound quality between these two? IE would it be worth it to sell these and buy the other logic 7 speakers with the larger magnets?

Ctuna,

thanks for the help here, but I guess what I am wondering is will I be able to tell the difference between the L7 with the small magnets and the ones with the larger ones. I am just trying to do a fast and cheap upgrade for now and am trying to decide if I should resale these on ebay and get the ones with the larger magnets for the back panel speakers.

The first link description of the L7 system says there are differences
in the L7 speakers . Doesn't categorize though.
It will be hard to find a comparison as most go for aftermarkets for major upgrades.

"Early versions of the Logic 7 system used metal-piston drivers. Supposedly various production dates sound better and worse."

Based on this I would thing earlier would be better.
