你玩過？？？？
Does F12 give heavy mid chest punching??
Actually F12 will not give you that. All of our subwoofers sound very natural. Some of the heavy mid chest punching is indication of a couple of possible problems: 1) one note bass (that all bass sound the same), boom boom boom, 2) congested bass sound. I have heard Genelec PA subwoofer that were very impressive to hear first. But as I listened a bit longer (as compared to F12 that I am so used to), I noticed the extension is chopped off below 30hz (PA subwoofers does not need go below 20hz). The mid bass emphasis is so strong, every bass sound has that boom-boom-boom flavor in there. In short, it does not sound as good when playing Enya. The goal of our subs is to reproduce very natural sound so that drums, double bass, and techno sound can clearly have their own sound texture. If customer wants to have more emphasis on the midbass, the best he can do is use our PEQ, center the frequency to 70hz or 80hz, and set the bandwidth to 3 quarter wide and set the gain to 3db gain.
A few pages back there was a post asking how to mix our subs with those from KK. I haven't heard KK, but I did hear M&K before. Since KK uses the same amp as M&K, I can imagine that they sound similar. So what does a M&K sound like? Punchy, but short note. What is how the customer feel there is a punch in the chest. When using a subwoofer with short note bass play movies with a building collapsing scene, the sound is again short note -- one boom, then it is done. But in reality, there should be ripples of after shock, so it should sound like BOOM,...little boom.. tiny boom...., which is what our sub will produce. So which one is the faithful reproduction of the bass sound? Now this customer can hear the difference from KK and while he likes some aspect of it, he does not like others. So he came up with this idea of mixing subs. I bet he is a good chef (I sorted hinted that a few posts back). All of these mixing, covering, and blah blah blah is not that what I recommend. So I don't even know how to start. He sent me email, ask in this thread. I don't think anyone has given him any guidance. On a similar note, I was told by a HK customer that several customers in HK mixing SVS with Rythmik subs so that they get the best of both worlds. "What???" I though to myself. The minimal they should is to turn on SVS only for this type of music/movies and turn on Rythmik only for that type of music/movies, not mixing them all together. I have been a critic of Gedde's subwoofers approach. I did not know there is an extra dimesion to the method. On the positive side, at least the customers can recognize the different sound from subs whereas in Gedde's approach, all subs sound alike and you just need to get the FR correct.
BTW, it is not difficult to produce a sound like M&K. A large portion of their bass sound is from the sound characteristics of RC4558 (el cheapo OP amp they used). My supplier initially used those on our amps (some 10 years ago). I spent extra length to take every one of them out. If someone is interested in that type of short note, punchy sound, maybe I can have a "special" version with RC4558 everywhere.

當然我吾期望佢會有MK嘅puncy, 自己亦吾鍾意，只不過想隻F15快番小小，同中低頻多DD，等佢同主聲道接軌好D，
, 因為我搬屋後會賣走svs, 但又想搵番帶有svs特質既十仔, 前級同十仔都係我換既目標之一.
