HD 15 vs TMS-3 (and others...) folded horn

This is so NOT TRUE, I don't know what you've been messing around with, did you use the xt8 horn? (otherwise this is probably why)

To me & us they sound much sweeter than my tms-2s, mostly because of the kick section, that straight kick just sound fantastic:-)
-Only proble being that they're far too big & heavy:-(

@TMS-3 vs hd15:
The designs are completely different, tse-115 series (tms-2/3 & tse-215) has a bigger front chamber and the orientation of the driver is completely different, have a look inside your box.

Cut over your tms-3s so you get an entire tse-215 and then glue a piece of bbply onto the side of the 2x10" highmid t get a tse-211 like cab.

They're not TMS-2s anymore then, look at the specification for the TMS-2 (or any Turbo box for that matter) and they specify that for it to be considered a TMS-x then it has to be loaded with the correct compliment of drivers in the correct box, for better or for worse...

I have 4 pcs brand new ls-1507 of for grabs anyone? :-) The ls-1507 is a bigger more powerful driver, looks more like pd.154, I think it has a 4" coil and takes more power. These drivers are VERY hard to find.

IIRC, the 1507 was for the TSE-115, TMS-2 etc to give it some more balls in a single element and that the dual-15 combinations where deemed to not need the extra weight, etc. because of the coupling efficiency

I'm not surprised that you don't care about words if you want to try and hold someone against something they've said that started with 'if I recall correctly'.

Evidently I didn't. I'm not that shocked, I don't really invest that much of my life into memorising every single part number-cabinet combination.

Calm down!

Ive only ever heard of people running these boxes as an interest/hobby so I reckon keeping them original is a large part of that experience.

Any one I know that has a passion for these boxes owns them as a hobby and if they run a business then they don't use these boxes and use boxes from this millennium

I had a look inside of my boxes, and i saw that there is indeed more space beetween the baffle plate and the rear panel in the TMS, as well as more distance beetween the rear panel and the panel that makes the begining of the horn.
Now, if you consider that the TMS is something like 6 cm less wide than the HD15, you understand that the two dimensions above mentionned have to be more important in the TMS  to end up with a comparable port area and front chamber volume as in the HD15.
At least, from what i could measure with the microphone, i could see that the tuning of both boxes is comparable; especially the roll-off in their top end happens at the same frequency.

i would say theses two boxes are two diffferent ways to do the same thing, and i agree that HD15 is not just a copy of the TMS series kick-bin.

Xtro can sound very good for electronic music! Bright and clean and lots of kick, but also muddy with rock music or so..
