We never said, I never said, the horn is bad. If I can only have one sub with a limited budget a horn is a no brainer. What is being missed here is that the comparison is not comparing alignments because one has so much more spl than the other and for subs that is a huge deal. Look at Data bass and compare the GH vs a sealed LMS 5400 ultra. The horn has much more output but you are talking a 27 cubic foot box vs a 4.2 cubic foot box. So what I am saying is that you can throw 4-6 LMS 5400 drivers in that horn box, power the crap out of it and now a sealed box will have more output and less distortion than that horn. I would bet many would pick the sealed in the blind. Blind tests are a wonderful thing with fair conditions of course.
I get it, If I compared my two dts-10s subs to my 3 SVS 16-46cs+ subs or a single eD 190v2 sealed sub I could say man, those dts-10s kick the crap out of those others subs, it must be the horn alignment, no it is the output, lack of compression, in my case more extension, you name it. So when I compared the 8 sealed eD 18s to the DTS-10s I still preferred the DTS-10s. When I switched to Fi car audio IB3-18s gues what magically happened, IB rule right? No, I had massive output, no compression, deeper extension, less distortion, everyhting was better. It was not a horn vs IB thing.
I stand by these comments and my own. its my semifirm belief that 50hz is 50hz no matter how you slice it. A horn may well eliminate distortion if very carefully built and theres no getting around that fact. Music lovers, imo, tend to love horns because they either have "left the building" when it comes to ULF or maybe never cared for it in the first place.
A sealed sub will in almost all cases be EQd to create the desired response...but they can play a fullrange better than the other alignments. Ported, if large and very well built can mimic most of a horns clarity and lack of distortion and can also play down much lower, esp when you reach the typical cabinet size of a horn.
Very few, even here, have really well treated rooms...and even those that do (i do) often have far from perfect room layouts to start from (i do). As such we all face choices.
If the choice is how to get really clear distortion free sound from the 30 to 80 range, we will be hard pressed to show with measurements anything better than a horn. Not a dts10 per se, a true well built horn designed to play a typical music subs range.
Likewise if one does care for or believe in concerning themselves with great respomse across multiple seats that also plays down to 10hz or below, DRs become a solution you will have difficulty out arguing DR fans with a horn. Horns "can" go low...if you provide conditions very very resource intensive -- tons of space, limited placement options...and it quickly becomes clear you are chasing a solution that can be solved much more efficiently with other alignments.
Then a few people have integrated multiple alignments,and enjoyed the benefits of all.
To the MAIN question-- I still respond that 50hz is 50hz. But in most rooms, 50hz will sound different if you play it at 110db using the different alignments.
Put another way, I am confident MK could build me a near perfect DR sub that plays from 30 to 80 without distortion and without much EQ and sounds just as good as a horn, Thats an opinion, not close to a fact. But ported or sealed subs that only play that range are usually crap subs bought from a well known brand, thus leading so many to look elsewhere and many to think ported sucks!
Theres no way around the fact that a well built horn can use very little power and with a great driver sound "perfect" in a certain range, and most DRs cant match that. But beyond that, my OPINiON is still that there are NO actual differences beyond the space they are played in and its own acoustic issues.
