Okay, the gloves are off. Let the fur fly


I would like to hear one single cogent technically accurate explanation of how a multi-way box speaker can be more musically accurate than single drivers or stats. As a speaker designer for more than 25 years, I have yet to hear an argument that holds water, technically. The usual response involves bass or treble extension, as if that is the overriding principle in music reproduction. My position is that any information lost or jumbled in the complex signal path of multi-way box speakers can never be recovered by prodigious bass response, supersonic treble extension, or copious numbers of various drivers. Louder,yes. Deeper,yes. Higher, maybe. More pleasing to certain people,yes. But, more musically revealing and accurate,no. I posted this because I know that it will surely elicit numerous defensive emotional responses. I am prepared to suffer slings and arrows from many directions. But, my question still remains. Can you technically justify your position with facts?

Ljgj, I had planned to stay out of this discussion so as not to color the responses, but since you ask, I'll be brief. Since I don't design drivers, I have primarily done various designs with stock/modified drivers. I started out with multi-way systems with simple and complex crossovers. I studied diligently, believing that if I could just get the right drivers and the right..... So, then I tried 2 way designs, same story. Now don't get me wrong, these were all good sounding speakers. But, all the tradeoffs. Slopes, cascading phase shifts with varying slopes, overlap problems, beaming frequencies, signal losses, driver matching, impedance fluctuations at varying frequencies with the corresponding response fluctuations, different driver phase shift angles added to the capacitor/coil phase shifts, corrective circuits, zobel networks, information loss, etc,etc. At some point, I became aware that if the whole ball of wax was simplified, more information could get through to the driver, with more coherent structure, due to the lack of the above. I am not promoting that any system is perfect. However, I am standing on the premise that more musical information, in a more coherent form will yield a more natural presentation, even if some aspects such as frequency extremes and even some dynamics are somewhat limited by the nature of a single driver. The idea being that a usable frequency range of extremely well resolved information is better than a wider range that has lost some of the information, and muddled it. Add point source imaging and my choice became clear. This information retrieval/retention theory has been standard in analog source design for years.You cannot retrieve musical information that has been lost earlier in the signal chain. I think it also applies to all other aspects of the system including speakers. I can see that I am in the small minority in this belief, but that does not deter me, nor does it mean that I am not correct. Perhaps the perfect driver has not come along yet, but if/when it does, the theory will prove itself. A driver connected directly to the amp, with no intervening components other than the necessary wire is the least offending structure to the signal we are trying to listen to.
Well I am told and I will be able to atest to it eventually, that Mike's system sounds well I hate to say it............uh here it goes perfect. In fact it is common for an applause from the listeners after a song. And if I recall I don't think he is planning any upgrades, though he will try new things, it usually isn't an improvement. My question is do you applaud when you are listening by yourself Mike?? heh heh heh, my system sounds as good as yours does after about the 5th drink any way!!!! booze is the best tweek regardless of drivers!!
I agree with Twl, common sense will tell you that a feather lite driver freely suspended will give more microtransient info than any dynamic driver. Planars and ribbons will also be able to dynamically rise and fall with ease. Seamlesness is not possible with box speakers using different driver construction and materials, whereas it is a natural fit for single source.
hi Tim, what i do in the privacy of my home and room is my business.....but if you must know.... i first get a big shit-eat'n grin on my face....think of how lucky i am to be able to enjoy my system....and then go to work (about 55 hours a week) to pay for all this great shit.

i hope when you make it out here to listen the system will measure up to all the hype...it is not perfect...but it doesn't do "bad" things and is about the musical message and not "parts" of the music.

someone once said; things should be made as simple as possible, but no simpler.

i think this thread is all about technical execution, and how to remove as many barriers between the pure signal and the listener but still do the whole job to deliver the complete musical picture. my Kharmas have a series crossover....the mid-range "runs free" and the tweeter and woofer have subtractive crossovers....minimum parts count....everything is cryo'd.....my amps have no output transformer, i use a passive volume control.....neutral cables....put it all together and you have the POTENTIAL for magic.....and it seems i have been lucky enough to have it.
