targa

[longthrow]

i've been using targa x150,is there a bigger (power & dia.) from targa models?....

[longthrow]

oh well scratch that........

The X-150 is the largest driver in my catalogue.

How does this driver sound? I have used the X-100 in the past and wasn't too bad value.

thanks!!!

they're great actually.. i've used 4 of them (x150dvc)..i was asking about targa because here in cebu, thats the only sub with the highest reliability (physically) & power thats locally available..& it just can't take the punishment from my bridged power amp (56V per rail)..

in my free air test,you can hear its voice coil bumping against the magnet with power applied less than 500W..even smoked @55Vrms..

i'd be glad if there would be a sub far better than this one that can be availed locally...

there's your problem. those subs are designed to be used in boxes. actually, any sub used in free air will not handle anywhere near its rated power handling.

I know a few people over here using a pair of those and Orion HCCA amps and getting 148-150db using termlab. and no, the subs didn't burst into flames.

The X-150 is supposed to be OK for 250Wrms with 500Wmax.

Looking at the Qts of 0.92, 3R9 impedance, might be OK for an OB with 2 in series per side. They are certainly cheap enough for a 15" sub woofer.

performance wise,i'm already contented with it in my ported box...

just curious,i ran a series of tests..my test frequency is 10-100Hz..
i was playing with it to see how well it performs so i did an excursion test (on free air;so as not to disturb neighbors).. i'm fully aware of a subs behavior in & out of the box though....but that is just my usual habit;always pushing things into its limits!!!

well now,can you help me what 15" or 18" sub (much more powerful than targa) can be availed here locally;any brand you'd like to recommend?

i appreciate your all your replies,
thanks guys!!!

You could always increase the power handling dramatically by using 4 drivers in a series - parallel arrangement.... huge box though. Try and blow that up.

I have an X-120i in a car sub, seems quite good for the money. Would love to get the T/S specs for it though...

[rabbitz]

For the X-120 single voice coil (don't know about the "i" suffix):
Power=200Wrms
Z=4R1
Fs=32.3Hz
SPL=89dB
Qms=3.69
Qes=0.61
Qts=0.53
Vas=85 litre

Hope that helps.
