TDA MT121 vs Original MT121

i.e. the original flare is 111.75db at 1.48khz

      the tda version is   109.8db   at  1.48khz

when u add and minus eq on the original to get a flat responce you can get it fairly flat at 110db before it drops off at 1.75khz

when u add and minus eq on the tda version you get a flat response up to 1.48khz......

hope this helps guys.....

i say just buy a better comp......

chill out matey 

there's no reason people can't at least experiment with playing paper higher. 

e.g. i know people who have crossed their MX450 and 600s at 3.2khz quite successfully and it gives full and clear response, with no ridiculous beaming. 

edit: typo

 

Can you enlighten me on the +/- eq values and at what frequencies to get this flat response.

 

Thanks Steve

i was not running test with the 2" the test were purely on the 12" run as low as it could with no higher cross over. 

Marjan, may be you did not no, but using 1 12" causes a massive dip just over 1khz with the original driver set out by roger Mogal, when you use the 12" horn in the original cab i.e. 2 12" horns this gap is alot higher up, hence why it is not noticed with a 2" comp.....

If you plan to use the 12" horn and a 1" comp you could run into issues with the original driver choice, i.e. a dip in the sound just over 1khz. This dip is even worse with the tda version.....

this info is nothing new its been talked about before.... there is some sims done with differant drivers by a forum member.........

the question asked was is there any differance in sound between the original and tda version

in my view yes..... in my tests yes....... 

but with the right 12" driver and comp set with very carfull cross over settings, you should be fine.....

all i have done is built 1 normal mt12 horn and a tda version and run a few tests....... because its fun to play with speakers...............
