Hi everybody, I am newish to home audio, but I am very good at car audio and I had the Idea of having a go at making a subwoofer box for an old car sub to use in my room for a bit of bass, can any one help me with the box design because I have tried WinISDWinSPK and have not had much luck getting a box that plays down to 20 ish. (I think the sub woofer driver is not very good low down)
here are the Paramiters for the sub.
Technical datasheet
Impedance (Z) 4 Ohm
Frequency range 35–3,000 Hz
Free air resonance (fs) 35 Hz
Crossover frequency (12 dB/oct.) (fmax) 2,000 Hz
Peak music power 450 W
Power rating 150 WRMS
SPL (1 W/1 m) 93 dB
Cms suspension compliance 0.45 mm/N
Mms moving mass 44 g
Qms mech. Q factor 3.84
Qes electrical Q factor 1.16
Qts total Q factor 0.89
VAS compl. equiv. vol. 180 l
RDC DC resistance (Re) 3.7 Ohm
Voice coil ind.(1kHz,Le) 0.4 mH
Voice coil diameter 39 mm
Voice coil former aluminium
Air gap height 5 mm
Force factor WxL 5.6 Tm
Eff. cone area 531 cm²
Magnet dioameter 125 mm
Magnet weight 30 oz.
Mounting cutout ø 282 mm
Mounting depth 130 mm
Dimensions ø 305 mm
Weight 2.4 kg
Am I wasting my time and materials with build a box for this sub (size of box does not matter e.g. 1-8 CF is possible by me.)
I would like to have a box that plays down to abot 25 hz or lower if possable.
Can anyone help me???

I can't really help you on the topic, but working at a retail store I have heard of customers who have used car subs at home and have blew their receiver. Just wanted to let you know. Could some great though.

You should post this in the DIY area. Should get a better response there. Maybe even ask the admin to move it there.

i'm interested in this...
my friend with the 1200 watt carver (you may have read my other post) is either gonna run an SVS 20-39 or two Polk audio car subs in a series off of one amplifier channel (to bring it to 8 ohms and to drop the output down to decent levels)
post back the outcome of your little project
