Seeking advise on sub using a TCsound 12" sub
HI,
I have been following this forum for quite a while ,now is my 1st post for advise.
I acquire a 12" OEM TCsounds driver with the TC9 motor.
The speaker is not broken, the following measurements were made :
Fs : 29 Qm : 5 Qe : .47 Qt : .43 VAS : 50l
Re : 3.3 Sd : 490cm2 BL : 16.7
Xmax : In the 25mm one way
3"VC 8" single spider
Similar drivers sharing this motor have a power rating of 500-700 watts continuous.
Simulating with Unibox and subsim shows that i will need 1400 watt rms to reach full
excursion in closed box 1cuft or vented box of 2-3 cuft Fb=21hz.SImulation also shows +11db at 20hz closed box vs vented .
Application is for home subwoofer.
I will be using a behringer DCX2496 for x-over. Do not have the amp yet.
i am wondering if 1400W would damage the loudspeaker ?
Is it typical to need such power to reach 25mm of excursion ?
Would you suggest a closed box or 2cuft Passive or 3cuft vented ?
Any suggestion on construction ? I am planning to use mdf, glued with woodglue and biscuits.
Regards
MIchel
