I have to take exception. All a balanced configuration accomplishes is greater freedom from hum and the like, due to the inherent rejection of common mode signals, like EMI induced hum. This can be an advantage only when hum is a problem or is audible, otherwise the signal suffers twice the degradation needlessly. I say twice the degradation because it is impossible for a signal not to be degraded to some extent merely by passing through any electrical device, be it transistor, capacitor, resistor, transformer winding or whateverr. Since fully balanced involves twice the number of devices for the signal to pass through, the resulting distortion from this is doubled, all other factors being equal.Is that technically better? Not in my books, but it is a very common misconception.In recording studio work it is more likely to be necessary and the convenience of not having to trace and deal with hum is often worth the degradation, but even in that environment the same misconception is widely held. In fact I had a lengthy online debate with an otherwise extremely well informed engineer about this very subject a few years ago. Part of the problem is that balanced connectors look so much more professional than the humble looking (and flawed-in-its-own-way) RCA connector. They click-lock into place and all that good stuff, but if you are in search of the ultimate sound, you want to keep the signal path free of needless complications. Hum is seldom an insurmountable problem in the home, but manufacturers know the cachet associated with balanced and are only too pleased to service that perception.
Russell are you engineer?please tell me
Has anyone had the opportunity to compare the M3 and M4 side by side?Are we only talking a difference in low end extension (32hz. vs 40) or are there other significant aural differences. The Turbo-S version of each seems to use the same compression driver so I would expect the mid/upper frequency performance to be similar as well.I have a fairly large open concept (living/dining/kitchen) space to fill but in terms of where I position my equipment I prefer the form factor of the smaller M4. Would the M4 with sub reinforcement provide most of the performance of the M3?However, considering that there is only $500 difference between the Turbo-S versions of each, which really represents the best value proposition?Comments?
Please tell me why you post negative comments that add NOTHING to threads all the time? I'm going to start reporting these kinds of posts because it's gone on forever and I'm getting really tired of the snarky attacks you post in almost every thread. And ridiculously, you follow up with some smiley emoticon to cover the blatantly negative posts.Here's a suggestion: Don't post unless you have something constructive to add to the thread. IMO, your negativity is against TOU and seriously degrades the quality of this forum.
2. I would damp the back of the big woofs with EAR SD40AL. The woofs have a stamped frame and killing the resonances of the frame will result in cleaner sound...
Magnet and frame all coated! I let the compound dry over-night so it’s completely cured. VB-1 is non-toxic, it’s not harmful to get on your skin, and there is absolutely no fumes or nasty smell to deal with. I get it directly from Cascade, so at the wholesale price per gallon, the extra cost per application (speaker cabinet or woofer frames) is minimal. The benefits are much greater than the small initial cost. I used to use adhesive-backed asphalt or vinyl based sheets on the interior walls of my cabinets. As far as damping properties go, the VB-1 is superior. It also sticks better, and is easier to apply.
Adding a subwoofer to the M4 makes the price difference disappear.
Tell us more, Don_S! Are you running your M4's with a sub, and if so, I'd love to hear the details. I've been thinking of going that route because the M3, I'm afraid, would overwhelm my little room (visually and sonically).Thanks in advance!
Rebbi,I do not have any Spatial. I was merely commenting on someone comparing prices between an M4 with sub and the M3 alone.
