as u can see the price difference aint much. soooo...i need u guys to tell
me which is best for me.

the sub will be paired with an Agako EG-2000D Monoblock amp and will be
used to listen to METAL \nn/. specs of the amp are as follows:

EG-2000D
Mono block 4 ohm / 2ohm /1 ohm operational
Balanced low input jack
Line out (pass through)
Variable low pass filter 24dB / oct (40 ~ 230Hz)
Variable bass boost at 60Hz (0 ~ 18dB)
Protection circuit for Thermal, Sp Short, DC Reverse & DC Offset

this is the specs for the Agako XT-3000D, which according to the
fellers at Agako Electronics, are exactly the same as the EG-2000D...except
for some minor
difference in the Frequency Response. specs in above remains the same.

Frequency Response 15Hz~250KHz
RMS power at 4 OHM Stereo 350W
RMS power at 2 OHM Stereo 700W
RMS power at 1 OHM Stereo 1200W
Max Power 1500W
T.H.D 0.1%
Input Sensitivity 200mV~4V
Input Impedance 10K ohms
Damping Factor >200
S/N Ratio 100dB


i need something that lasts meaning can take a good beating.

one more thing...was also checking out the Alpine DDDrive 12" (DDW F30A). cant seem to find specs online. mebbe coz its a discontinued model? any thoughts on this one? heard that the DDDrive are quite legendary.

so gimme ur votes, thoughts, opinions.

thanks again guys

cmon guys.....anymore votes on the woofers i posted?

count so far...

4 for Type R (3 from AW forum)
1 for MTX

anymore

okie boys and girls....just got back from doing the sub thingy.

went for the Type R.

although i preferred the Type S @2ohm...i was worried about burning the sub coz even for a short test can smell something liao.

tested the Type R at 4ohm with some tweaking and yummy. so decided to go to the safe side



**total spent on ICE so far RM9370 **

the total is inclusive of all parts currently in use AND also all parts that died/ upgraded/ changed/ reworked etc etc etc.

if the parts in my sig (in use) only then itll be significantly less....

i aint insane enough to be overpaying for anything ler

i know....simple reason being itchy... this subwoofer thing oso because my woofer pecah liao. so needed to change

actually...most of the extra cash was because of changing this and that... this is my 5th woofer liao...still havent found the right/ workable combo yet. been having problems with the woofer setup coz of amp & woofer mismatching causing burns and pecah and bla bla bla

actually i dont really mind the total ive spent... coz its not like i spent all of it in one go... the whole thing is over a period of 3 years. a few here and there added together kinda thing...so not so bad.

@koniglee
im not bothered with home hifi...im pretty happy with my current HTPC + Edifier R501 MK-II. no intentions of changing/ upgrading them.

id rather spend on upgrading my headphone setup as i use that the most.

ahahahahhaha....running muh woofer at 4ohms now. dun dare run at 2ohms...last i did that with my alphasonik woofer the damn thing started smoking in less than 2 minutes!! which is the cause of the pecah and the change to type R oso la

even the type S @ 2ohm oso started smelling something after a short test. so i guess 4ohm is the best for now...

gain on amp is not that high...around 1/4 only if i remember correctly...actually planning on lowering it a lil more.. this Agako im using has HUGE amounts of power man

problem with listening to metal...the boom boom level on diff songs can differentiate ALOT. current setting might be nice for this song but may be too little or too much for another...heh. dont really have the time to get it right yet.

bad for wallet? tell me about it

amp is wired as per normal lor. i cant really remember the settings of the damn thing but have to take off seat to check. its the woofer wiring...could be the bridging la...dunno...

but so far if i run on 4ohm the woofer has a higher chance of surviving the puches i give it. so ill leave it for now la.

been thinking of taking off the seat to tweak the amp...but really no time ler sigh

cool dude.... i wouldnt mind ur help with the wiring

would be nice to meet up with another ICEr

aiyah...all this talk...when wanna meet???

can come my house la like that...my garage is shaded...

manual for the agako is missing... cant remember where i put it

yep...muh house is in PJ...

but someone need to bring tools and some parts if needed.

and of course sunday is the best option for me too. and this month may not work out well for me oso...april has slightly better chances

looks like it

already bought the 12" Type R

my type r is still running fine man

havent smelled anything yet...

anyway...u guys figure out a date for april la...and ill see if it suits me... i just found out that april gonna be a busy with work month for me..... still might be able to make ti but depends when oso la...

if im not mistaken mid april should be fine.
