TV,
:: Have you reviewed our discussion regarding the amount of volume one should expect when adding a second *titan*? This is very basic knowledge...and yet, the discussion has lasted nearly a dozen posts ...simply because he either has no idea of his error...or he won't admit error. Who is served by letting such misinformation go un-challenged? ::

First, I have no problem with that exchange and I beg to differ about it being basic knowledge. Your assumption that it is basic knowledge explains your tone (or perceived tone) in that exchange. I actually think that there is a great deal of confusion on the subject and I admit that I am not sure of the facts myself. OK?

If you double cabinet volume, double amplifier power and double the drivers used, yes, I think you are correct, you get an additional 6 db of volume-when it all takes place in the same enclosure. Once you separate them all into two different enclosures with two different power amps, I’m a little fuzzy about what happens. Deon chimed in that it has to do with the relative distance of the enclosures vs the size of the wave-lengths produced and that makes a lot of sense. Perhaps had you been able to articulate this to Stuart, your discussion wouldn’t have gone on for so long. But rather than doing so, you instructed Stuart to go look it up….where, on that subwoofer design book he has sitting on the coffee table? When ever you instruct people to go research a project rather than giving them exactly what they need to know, I think you can expect a protracted conversation.

:: where have I even suggested what listening level to use...EVER? ::

I’m not going to go back and search through all of that thread to find the exact words you used, but your continued citing of reference levels and citing measured response of the Titan, I believe, implies that everybody listens that loud, and that the Titan will deliver an unsatisfactory performance- which is really our only area of disagreement. I don’t think that many people listen that loud and I don’t think that many people will be disappointed with the Titan’s performance.

::I posted that IF you DESIRE to listen at *reference* levels...the titan isn't the best subwoofer choice(paraphrasing, but I think accurate). ::

Well, I accept that as your intent. But in the context of the thread, between you and Patrick, I think that point became a little “blurred”.

::Nope. I'd suggest what car to purchase based upon their performance expectations. And that's exactly what I've done within the context of this thread. You want *sports car performance*...buy the talon....you want a *smooth ride*...buy the Crown Vic. As long as the Crown Vic owners don't spread misinformation regarding the performance capabilities of their vehicles....there's no problem. ::

Again, I accept that. As a Titan owner, I can vouch for the fact that I have not seen the Titan’s capabilities misrepresented by anyone here. Mike Dzurko himself was the first person to accurately characterize who it was designed for. Shawn has said over and over that the Titan is not state of the art as far as SPLs go, but opined that it was a satisfying subwoofer- that coming from an owner of a contrabass!

::Well, I can't say I'm here to join in any *group hugs*...nor do I care to include myself in any *let's pat one-another on the back mutual admiration societies*. ::

LOL!!! If you had ever witnessed any of the battles that Stuart, Shawn and I have engaged in on the Compuserve Audio forum, you would know that that is most certainly NOT what Im talking about! :-)

::I try not reduce the discussion to a personal level, and I always try to base my opinion upon objective data that has been published for all to see. ::

I can respect that. I think that the problem between you and I is in the interpretation of that objective data. Sooner or later, objective data must always pass through a subjective filter. Obviously, in the case of subwoofers, you are loaded with objective data, but the problem comes when trying to put a subjective face on that data in order determine just exactly where on that scale of dBs comes the “acceptable performance” level. The same can be said about most objective measurements- the question is always at what point do differing measurements relate to issues of audibility/acceptability.

And of course, objective data on SPLs produced by a subwoofer is an incomplete method for determining a subwoofers total performance. It ignores all criteria related to "quality".

::I agree, but at times...SOMEONE has to be *right*...or little knowledge will ever be gained? ::

Some issues are black and white. Your discussion with Stuart is one such issue. But this whole Titan thing is anything but black and white and IMHO, the debate just went on for way too long. I mean, how many times can one express an opinion? And make no mistake, ultimately the value of the Titan (and the HSU for that matter) will always come down to a matter of opinion based on one's preferences, needs and expectations.

::During various discussion of bass reproduction in the typical h/t room...I get corrected almost DAILY...it's no big deal...that's way I enter these discussions in the first place...to educate myself further.
I guess everyone doesn't share the same POV though? ::

Well, now that I’ve “lectured” you twice, I’ll give you your due; you do seem to have done your homework and you have a pretty good handle on your subject matter. Our only areas of disagreement are in subjective realm and you know what they say- “One ought not debate matters of taste!”. But then again, it happens everyday in cyber space, doesn’t it!
