Hi

Nobody should say it is bad if they haven't tested/heared it, most of us even don't know what could be good speaker, from pics or graphs...sry I can't help...look good

hi luka, Thanks for your reply,
The speaker is dedicated to the design of automobile,
The shell is CNC of aluminum.


thanks
jam

It looks spectacular to me.

The mount doesn't quite match the cosmetics and quality of the CNC'd housing, a machined mount would look better, but I'd be very proud as it sits.

As far as FR graphs go, yours looks great. What are you unhappy with?

Is that a Vifa XT diaphragm & phase plug?

Thanks for your reply,

this sounds very exciting,

but, my customers and I think it is not flat, (2.5 -3K, after 20K), we hope can do more smoothly.:(


Yes, this is the study of the practice Vifa XT.

:cheers:

Is the frequency response graph with or without the cover?
Also what are the dimension of the driver?
