RE: Acquired MGIIIA

I just got a pair of IIIa's from a recycler for cheap. They only had one mid and one bass driver working when first tested. Checked the ribbons, both were not soldered correctly. I attached jumpers just to get them working, and gave a listen for a couple of nights. To get some balance in the bass/mids I connected one T-IV bass panel to the bass output section of the IIIa crossover box (not ideal, but to get -some- balance, it worked).

My initial impression is that the IIIa is much more forward in the midrange than my modified T-IVa's. It's good in the sense that the vocals are more forward in the presentation, but a bit of a loss in the total image because the musical program gets reduced, at least in the mid-highs and the mid-lows. This could be a reason why people tend to consider them 'power hungry'. Increasing volume will bring up the background, and your ears will attenuate the vocals as SPL increases.

Keep in mind that I didn't do any proper placement, or room EQ and they were sitting directly in front of the T-IVs. Still, amazing sounding even as such. The extreme highs seemed to have a bit more sparkle than the T-IV's do so I'll be looking into why that is, but it could be lack of room EQ on that issue.
