Magnepan MG-1 sonically challenged?

i have a pair of MG1, in excellent shape, i run them in a 3-way active crossover system, quad 303 as woofer-tweeter configuration and polk audio 10 inch active subwoofer, the sound is precise, clean and incredible,i rewire the tweeter 3 years ago with great result. it please my ears so much that never i will let go my sound kit.

I enjoyed my MG1's for years, then I tried a pair of MMG's. In my opinion the little MMG's were better, even though they were much smaller in size. They actually seemed to resolve the bass better than the larger MG1's. Also consider my MG1's were re-built at Magnepan years ago, and as far as I know, they were 100% working properly. Later I upgraded to 1.6's which were in a totally different league. Again this is just my opinion, but the MMG was a step up from the old MG1's and the 1.6 was a huge step up.

Have not a/b'ed directly but I think the latest and greatest Maggies including mmg have better dunamics overall than older MGs.

Hi,

I bought a pair of MG1's and a pair of MGIII speakers today.  One of MGIII's tweeter sound only no bass nor mid bass?

I really need your help how to fix the current problem! how to dis assemble that MGIII speaker to look for the cause.

Thank you very much for your help in advance.

Best Regards,
