Hi All,
I am new to this forum but have been going through a lot ot the previous posts over the last couple of months. I have been facinated with the word of audio. However after coming acros this site i realised it would be so much better to design speakers oneself and experiment to getthe music that one likes ratherthan shop for the closest to one's taste.
This becomes all the more imperative since I am based out of India where their is very few choices in terms of speakers and amplifiers. Hence this is my first foray into building a speaker.
I have taken a simple 2-way book shelf speaker and tried out some Vifa drivers (Again since I don't have too much of a choice in terms of driver availability)
The drivers that I am using are
VIFA TC18WG49-08 - Woofer
Specs are
Qts 0.47
Vas l 44
Fs Hz 37
Re Ohm 5.5
Le mH 0.75
Xmax mm 4
Z Ohm 8
Qms 2.62
Qes 0.58
SPL dB 86
Pe W 35
BL 5
Dia mm 25
Sd cm^2 138
AND
VIFA D27TG05-06
Tweeter
Specs are
Qts 0.77
Vas l 0.006
Fs Hz 1000
Re Ohm 4.6
Le mH
Xmax mm 0.2
Z Ohm 6
Qms 2.15
Qes 0.19
SPL dB 92
Pe W 100
BL 2.7
Dia mm 26
Sd cm^2 7.1
I have adopted a simple 2-way 2nd order passive filter
with the crossovers set at 2800
I have also used a Zobel network and an L-pad attenuator.
I have attached an xcel sheet that shows the values of the crossover network used.
I am trying to keep this as simple as possible since this is the first speaker set that I am attempting and would like to learn from here on.
Also pls keep in mind that I have access to absolutely no measuring instruments, etc which will help me to figureout the behaviour of my drivers.
Hopefully once I am done with the crossover, I can moveon to the actual buidingof the cabinet.
Pls letme know if there are any problems withthe crossover network.
I am using WinISD and Speaker workshop. I have also downloaded some more sheets from various DIY enthusiasts across the net for designing the cabinet and also for various filters.
PLS HELP............................
