Raul,my feelings on the subject are from "real world" experience,as stated,as well as careful listening(by myself, and other hobbyists I respect,who have actually heard ALL of "my" systems over the years)and believe it or not, somewhat of an understanding of the "system/room/design goal of the specific hobbyist" who has the option to employ "STUFF" as he/she feels is most effective to them!...Without the arrogance of someone telling them they don't understand the subject!
And PLEASE get off the "IM distortion thing"!!!I don't hear "it" and either would you!!!....
The thing "you" simply cannot understand is not everybody thinks in an actual textbook fashion,once the "listening experience" speaks to us.Some folks should,rightly,make configuration choices based on what they hear,in their room!...Period!!....Also,I have no reason to believe your system sounds anything less than superb,as I respect your word.
BTW,yes my REL Stentor is ported,but it comes in "below" my main speaker,and the "pitch definition"(something I am beginning to doubt you have really ever experienced)at this "low freq" is far less obtrusive on the main speaker,as it would be if one was to cross over as high as you adhere to.To my way of thinking,and with my speaker,a big mistake to cross over higher up!Sorry,it's my call on the subject,and I will bet I am at the very least as crirical as you....
BTW,don't take any of my input as my being upset,or mad,as I am not!!..I am "actually" waiting for my wife to come home,so we can go to dinner.Hence, the time to keyboard for awhile,hopefully in good spirits.I got carried away with this kind of stuff two years ago,with another poster,and have learned my lesson about pushing it too far!
Also, if I were NOT very attentive to "all things audio" my friends are SO rediculously critical that they would mention any distortion/aberrations in a New York Minute!
Take a look at the BIG Nola Grand Reference(I have extensively heard this HUGE four tower design,as a client owns one).The main towers have "sealed" midbass drivers extending down to 40 hz.The secondary two sub towers,are ported,and designed to come in below 40 hz!They,the ported sub towers, are the achilles heel of the design as the "pitch definition" of the ported towers cannot match the sealed mid bass drivers,BUT it is SO much FUN to listen to the speakers,that one just does not get bent out of shape over this.Of course you would -:)That was a joke,btw!
Btw,Raul....I don't know why you are getting so excited about all of this.I am not stating(like you do to me...but I love you anyway -:)that you don't know what you are talking about!...I am simply giving you a counter arguement,based on my experiences,within my own systems,and others I am intimately familiar with.
I DO get impression that "some" have not necessarily heard what really superb pitch definition sounds like,at very low frequencies.It is very much like finding the EXACT sweet spot on a very good "arm/cartridge" set-up.Sometimes we fish around for a long time before hitting the magic.Once you hear/experience it,you know it!
You simply have to be able to accept alternative positions,without arguing that the person doesn't know what they are talking about.
Personally,I feel that "you" don't seem to grasp that I am NOT stating two subs are not most effective.I am stating,based on actually owning three or four of the system types(including my current one,which I consider the most realistic and involving one I've had so far...but I am NOT saying it is the best of "anything",only it serves my tastes)covered in this discusson that "conditions" DO exist where the "TWO SUB" option is not "mandatory",as you imply!AND,it does NOT mean you automatically have IM distortion issues(or you don't understand the "sub" issue) if you go this route!
What don't YOU understand about "that"!! -:)
Best....as always,and I am wearing my football helmet as I await your response!....also a joke.
