Saying "there is no such thing" is what is "silly."
In my head your post reads, "You would not hear a difference, or coloration. The enclosure doesn't effect the sound produced by the driver at all. Changing the enclosure only changes the Q. Nothing else could possibly change... and that is what... you... could hear... umm, but the Q change you heard had nothing to do with the enclosure used. It was caused by... something else... unrelated to the enclosure, of course. Therefore the enclosure has no effect on sound. You can hear a FR change, but that is something else unrelated to the enclosure change the Q, and you can fix it with EQ if you feel like it anyway, so it doesn't exist.
" Come on.
Tell you what, lets ignore subjective for a moment, name one measurable parameter that doesn't change when altering an enclosure.
Moving on, so someone needing more "mid bass slam" is a joke... but if someone somehow had a lack of "mid bass slam" for whatever wacky reason they could add EQ in your opinion to correct it? OK. How is it a "humdinger" again, or any different from what has been said here already?
It seems like the whole point of your post was just to toot your "my multiple small sealed subs do everything better in every possible situation, than anything else in the world" horn.
You are starting to sound like Stevie with LLTs.
First things first:
By SQ I mean playback uncolored by the enclosure
You said it, exactly. It's what prompted my response. I've read it many times. It's as incorrect every time I read it.
I think it's the "In my head, your post reads..." part that's giving you a comprehension problem. Try maybe having someone read it to you.
I'll try to make it as simple as I can for you...
There is only one alignment that can achieve this in-room FR with headroom and inaudible non-linearities:
The following graph is of one subwoofer. You can knock yourself out as to which is the native response and what that might mean to your box coloration theory, especially if this graph were of an IB.
Since each of those FRs evokes a different set of subjective comments, where does the 'coloration from an enclosure' idea factor in?
Since a sealed system includes an IB system and the FR can be matched using any properly designed sealed system, coloration from the enclosure is BS.
Here's the point, and sorry I can't type it slower for you; given the same FR with the same lack of non linearities and the same headroom, the presentation will be the same and will be perceived as the same and described similarly.
Yes, I've tooted that horn for a long time, mostly because experts like yourself keep posting nonsense to the contrary.
MKT (who, for the record, I think is one of the coolest cats ever) has referred to 'the horn sound' in comparisons of different alignments in his theater. His opinion matters more than most posters because he's graphed and compared ported, LLT, sealed and TH in the same room, but I argued that there is no such thing as a 'horn sound'. Although MKT's measurement hardware is less than ideal, there is still good evidence in that there is a relative comparison to be observed. There was only a significant FR difference at the LP between them, nothing more.
It wasn't box coloration. It wasn't the horn sound. It wasn't mid bass slam.
Danley attempted to defend the 'horn sound' theory as being attributable to lower group delay. Since GD is a derivative of FR, this was shown to be an incorrect theory, although that probably won't stop experts from arguing otherwise.
Getting back OT, there are 4 disadvantages to the IB vs a boxed sealed system; 1) when the ambient temperature can vary from 45 degrees to 130 degrees, performance is affected. E-mail Ilkka and ask him what comparative value his measurements would have if the ambient temp varied that much from test to test. 2) An IB can't properly use the corner(s) of a room. 3) Placement tweaks are not possible. 4) Mid bass potential must be limited or HP filter protection must be employed, there's no getting around it.
On an unrelated note, for the record, I don't consider your childish reference to Steve Callas as the slight you intended it to be. Steve has had a lot more to add to the hobby than your condescending blurts.
I too am glad to see you back posting.
