Anyone know how i in the future get the DCX2496 to work 4-way active, guess i need some more dsp?

Run Subs and Low in mono, Mid and High in stereo.
Input C can be used as a seperate Sub send if you need/want it.

Or put a second DCX at work and run each as a 4-way mono processor with two spare outputs for infill/sidefill/center/delays/...  Two inputs are also free to direct to whatever output you like or make any matrix mix of the inputs to route to each individual filtersection.

Beyma cp-300 sounds much softer and more comfortable but you have to +db around 10 000 for them to come out properly

B&C driver sounds very sharp "tick tick" :) from the start. so this one you must instead reduce a lot db to get it to sound good.



If Beyma drivers have 16 ohm diaphragmas and B&C 8 ohm, this would be the case.

And since you have them apart already.
I would sugest for the greater good of all mankind, get som pictures and maybe measurements of the Turbobass chamber.
Because there has been so much speculation on how it's made up and what it looks like and so on.
I think alot of people would be really grateful, I know I would atleast. Smile

back on topic, the B&C is the wrong driver for these boxes and I'd sell them for some CD-102s to match what you have, the Beyma's really sing and unless you want to use them in anger all day long IMHO are sweeter than the EV (CD-103s) but eh B&C has no place in that box, but will get enough cahs to fund the correct drivers!!!!

Is there any plans for tse-115 I tried to sim this as a part of the tms-2 as i could find no other sims only hd15 which is actually quite different.

Other drivers play very well in tse 115
I know people like to use pd.184 in tms-4 / tse-118 over here in DK

I've heard a PD-184 in TSE-218s (Ok I've heard 2 of them!!) and they work well but fart about 200Hz so don't really make teh 250Hz the TMS needs to hit the 10"...
 
The TSE-x15 is a TMS-2/3 bottom end and again requires an mentaly quick driver, a Fane Neo 15" would be my starting point, but I can see you won't get to 250Hz clear....Smile

How can you see that?
First I simmed it as the best.
Then we've been blind listening and measuring with the boys, mb15n401 won!
RCF was far more linear
Fane studio 15b was quite similar to the original ls1506 and it's cheaper, they had quite a boost around some freq i forgot which.
pd.1550 was game over

I've tried various driver and the issue is pure acceleration, back in the day 3 and even 2" VC drivers were about in abundance, we tried loads, none were quick enough, a 4" VC RCF isn't gonna touch an LS-180x let alone a LS150x, Turbosound is all about "transient response" not SPL or low end extension, you wnat low-end breakout teh TSW-124s and PL 9.0s, the recent trend in driver development appears to higher power handing (the LS-150x was, from memory only 250-300W) and more low end extension, more power handling mean more copper on the VC which is more mass, more lo-end extension means more excursion, again ends up with more mass, more mass means 250Hz is a dream...
 
So yeah I knida "see" a 4" VC driver will never work, as for blind listening, with what program material, if you want it Hi-SPL, MP3 freindly,  "banging" then I can see the Turbo drivers are easily bettered, if , but if you want a pretty flat response Turbo box, you are screwed....

Ok Shagnasty, we're running a bit off- topic here regarding tms-2.

The fact is that the rcf neos ARE MORE FLAT! We did measure that plot throughout!
Perhaps the ls-1502 and fane studio 15b have been a bit worn out?
From 4 peoples ears with different taste of music rcf simlpy WON being more transient!

Take a look at the specs, it's a very fast driver!!!

Take a look at the theory then:
I've seen quite a few 15" horns crossing at 250hz
Look at the xtro's, people cross them far above 250hz

Big respect for turbo & their nice transient sound, I think it's no wonder if this box can be improved after 34 years on the market.

I have 4 tsw 721's and 4 tms-4's and a turbosound lma d6 processor why do I figure this
Is going to be a headache to make it sound right?
