Recently picked these up locally for a good price. (I thought anyway)

I know these are not the favorite of the line based on some of the few online threads and reviews I could find. So I figured I would snag these to have spare parts for my Braun L-710's that will be with my till the end.

So far I have only listened to them in my shop at work on a little Lepai amp but after not really expecting a whole lot of wow I have to say these sound really nice. Like a very nice two speaker but with better bass, a little boxy with certain types of songs but mostly tight clean bass. Looks like an early MTM design. Cabinets are very well made and solid as you would expect, grills are tight and mostly clean. Woofers have some schmutz on them on the rubber surrounds that wont clean off but not a big deal.

Granted it does not have a separate midrange but that job is handled pretty well from the top woofer. On some songs its a little bit diminished but in a good way if that makes sense. Going to get them hooked up to some vintage tubes and see how they sound, bet its pretty good. Only running my Wes Montgomery channel on Spotify through them cause I am on a vintage jazz kick at the moment. :beatnik: Heard some newer John Scofield and Larry Carlton through them and they really snapped to life. When I get them home I will have to try some good rock and classical music.

Probably freshen up the crossovers and fix a small veneer chip and keep these together. No they are not the 710's but they are a different speaker in a good way at least to my copper ears. Keep a look out for them you might be surprised as well. Great Braun drivers in a solid cabinet.

ADS started out as Braun's importer, and their models were often very similar, using the same drivers. So not surprised that you like the sound. But I don't think MTM is an accurate description - I believe it refers to a tweeter between two midranges so that the polar pattern is uniform.
And what is with the Moretite oozing out from the tweeters?
 
They are sealed good from the factory aren't they.

As far as the MTM design goes I think you can say "I missed by that much chief" when these were made.

The more I play them more I think I will keep them together.
 
I doubt that the moretite is factory - Braun and ADS both were much neater than that. It's possible someone was in there to recap and was a little too enthusiastic when remounting the drivers. With the grill on, of course, no on knows.
 
I have an early pair of L400s that are mounted the same way. It has to do with the size of the tweeter magnet as compared to the size of the mounting plate. The putty is used to seal the gaps.
 
My 710's are similar but the putty is a darker color.

A quick check of images of the L700A on the internet show this is typical.
 
I am surprised that so many pictures of the L700A show putty oozing out from behind the baskets. Not only do I wonder how this went over on the German market (or any market actually - who wants to pay top dollare for what looks like a home made speaker?), but applying putty is a time consuming activity, which, I assume, is why most manufacturers use foam.
 
I notice the cardboard gaskets - I think the putty under them is a later addition (not to be a one not Johnny on this issue).
I've had those square caps be out of spec - worth checking to see if it needs replacement.
 
That’s pretty nice. That’s a film cap right? No lytics in sight. Probably good to go.
 
IMHO the sound would likely improve with quality modern caps even if the originals are film. In the majority of cases manufacturing techniques and materials have improved.
 
I probably will change them out at some point but to me these sound very nice as is so I might leave them in.
