Seeking advise on sub using a TCsound 12" sub
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.
You sure the Vas is only 50L?
That power rating is for thermal power handling no doubt. So your 1400 watts would make it light up.
I'd go ahead and use the Parts Express 1000W subwoofer amplifier. They have a tabletop version and a plate-mount version. You're in Canada, so I'm sure that there wouldn't be much trouble in obtaining this amplifier.
