The old trick for breakin of speakers was to wire them out of phase, then make them face each other a foot or less away from each other. Then letter' rip. They will mostly cancel each others' output that way, so you won't hear them. With open baffle this of course doesn't work as well. When I went through M1 breakin, I would lean 2'x4' GIK acoustic panels up against front and back in the morning before work, then crank the volume. 9-10 hrs a day of that while I was away for a couple weeks got me through the bulk of breakin process. Subtle changes after that.
Okay sports fans.... The M3's were delivered today. I think I can put the amp pre-amp question I originally posted to rest. The Decware Torii MK IV/Don Sachs SP 14 Model 2 obviously have what it takes to make them sing. I see no weak link there. Now for this break in thing. Of course I had to un-box them and hook em up. By the way, they were packed extremely well. The exterior of the shipping boxes had some gashes and divots in them. Once unpacked, the speakers were pristine in appearance. Check.So I fired up the amp and pre, let them simmer for about 20 minuted and then got down to it. (No, I wasn't dancing.)First short version of honest impressions are....Oh, and my wife sat for a while and said the vocals were better and that the overall sound was "more clear". The Good:The best vocal from any speaker I've ever heard. Period. And that was male or female, loud or soft, whisper or scream across every genre. The articulation was fantastic on everything I played. Percussion.... Drums, cymbals, glockenspiel, triangle, rim shots, you name it, it was all there in spades. The Bad....Some mids are a bit too forward. The high register, especially in the higher register on female voices is hard; what I call a bit strident and overpowering. So much so in fact that the mid/highs really help exacerbate the observations about the bass response below. I think I read this will relax? If possible, I would like known outcomes from owners. So share your thoughts here and on the next line.Most disappointing aspect was that there was very feeble bass extension. In fact, until I jacked the volume up to achingly loud, there was very little bass of any kind. I would blame part of this on the still newish Duelund Caps in the Pre, however the Cornwall III's have no such issues with the same tracks. A side about the previous note on bass response. I am optimistic. When I bought the Cornwall's, I got them from a guy in a bind who needed to sell them. To be honest, I bought them to make a few hundred bucks. At first, they were terrible. No bass at all. I chalked it up to room placement and old cd's and even older compressed recordings. (And I do believe compression was a mitigating factor) But, after five months, they've really came alive. so much so that I actually love them. I would credit the pre, but they were sounding a lot better before I introduced the line stage. So I went back and read the email from the guy I bought them from. At the time, he couldn't tell me for sure how many hours were on them, but he guessed less than 100. They had also been sitting unused for months. All of this to say that I believe the Cornwall's coming alive is likely a combination of being played extensively for the last several months, and some micro tweaks in terms of placement. Bottom line, I'm hoping the same happens with the M3's. One way or the other, there's only room for one pair of speakers in my room.So, if you happen to be passing through Gastonia, NC tomorrow on I-85 and hear loud music, it's just my Spatial M3's loosing up for their audition.
I have about 75 hrs on my M3s (I received them last thur). With an Emotiva Stealth DAC running into the S500, I definitely do NOT have any bass issues. But I know what you are taking about referring to the forward sense of the mids. But I need more listening time to make a final decision. For fun, I'm going to run the M3s tonight with a $500 Marantz PM5005 integrated amp. Should be interesting to see if I can hear a difference.
George, I noticed on another thread how you received your M3's on June 4th? And then I think it was June 26th when you posted your impressions after initial run in. Just curious; can you guesstimate how many hours you had on them at that point? I think I must have a little over twenty hours on them. The top end has lost some of that strident sound. It's obviously smoother. The low end bass extension is perhaps a tad better. They are definitely capable. I played some bass tracks (Albeit louder) and some test tones below 30Hz and they were able to dig them out. I'd like to fully run them in so I can give them a fair shake before I get anywhere near the 45 day point. I don't want to leave my Decware Amp running all day while I'm working, so I may hook them up to an older JVC HT amp and run it in pure audio mode for a couple of weeks. Any thoughts or suggestions much appreciated.
