Hi guys,

Quick question, I just got my SA-8 and will be bridging ch 3&4 on the SAX 100.4 to power it (~320w @ 4ohm). I read the box size recommendation post (1.25ft^3 for around 325w) can I go smaller say .8ft^3? Will it still sound good with that amount of power?

I think that it would; what you read was power handling at a certain box size; that doesn't mean you HAVE to run that box size at that power.

Jacob,

I know you will post when they arrive but do you have an ETA on when they hit customs?

Im trying to get my recone kits before the south texas meet.

[kkk4 3]

jacob, you have pictures of re-cone?

[sundownz 197]

jacob, you have pictures of re-cone?

I sent you photos of all parts -- but I do not receive my shipment of parts to build any more re-cones until end of this month.

[kkk4 3]

ok, I see a photo of full recon kit complete

today arrived my sa-8

aesthetically are really very beautiful and massive

you can view the photos at this address:

spl, for use, I recommend the best configuration to make the most out spl?

burp at 60hz

2 SA-8

1 saz-1500D

How big the box, that tube diameter and length?

has anyone tried?

[sundownz 197]

1.2 - 1.5 ft^2 enclosure with one 8 inch port... start with length around 12" and then adjust to create highest SPL at 60 Hz. Woofers facing to front and port facing to back.

Calculation may not be correct with port length so testing is needed.

[kkk4 3]

Thus about 34-42 liters, tube 20 cm (8") about 30 cm long

course are theoretical calculations, but I needed as a starting

[kkk4 3]

and a car given to 73hz? How big the box?

2 SA-8

1 Saz-3500D

for SPL

2 SA-8

1 Saz-3500D

for SPL

I made a box of 35 liters, with pipe diameter of 16 cm, 19 cm long.

burp at 73hz, but the result was very low!

car grants to 73hz, but the box does not load

60hz is much more, so I'm totally out right! What do you recommend?

[sundownz 197]

To peak at 73 Hz you will need to tune likely around 64-67 Hz... try pipe length of 29 cm

If this also does not work try pipe diameter of 10 cm x 9 cm length.

Phase may not be correct from woofer to port opening... photos of box ?

[kkk4 3]

Tomorrow I take a picture, however it seems that cash is not loading well, seems to play inside and not to create pressure

definitely a tube 29 cm would improve, but with a tube of 19cm marks 140dB, so I think we can greatly improve, plus 29 cm, I would go too high with the tube....I try to pipe 13 or 10 cm as you said

I list one by one all the settings to set amplifier?

Edited May 18, 2010 by kkk4

[kkk4 3]

still small problems

I made some changes, but the results do not change in this car

will list all:

FS car: 73Hz

Box volume: 35 litri

Measures: 26x73x27 cm

Subwoofer: 2 SA-8

Amplifier: 1 Saz-3500D at 1ohm teorical

here are the various tests with different airport, and different lengths

diameter 16cm, length 17cm, theoretical accord 75hz :

burp 60hz = 136,1 dB

burp 55hz = 135,0 dB

diameter 16cm, length 25cm, theoretical accord 67hz :

burp 73hz = 132,2 dB

burp 65hz = 136,6 dB

burp 60hz = 138,1 dB

burp 55hz = 137,0 dB

diameter 16cm, length 36cm, theoretical accord 60hz :

burp 73hz = 133,3 dB

burp 65hz = 139,0 dB

burp 60hz = 140,3 dB

burp 55hz = 141,1 dB

diameter 16cm, length 47cm, theoretical accord 55hz :

burp 73hz = 131,7 dB

burp 60hz = 140,0 dB

burp 55hz = 141,2 dB

burp 50hz = 141,0 dB

diameter 13cm, length 10cm, theoretical accord 73hz :

burp 73hz = 129,7 dB

burp 65hz = 132,4 dB

burp 60hz = 133,6 dB

burp 55hz = 134,9 dB

diameter 13cm, length 17cm, theoretical accord 64hz :

burp 73hz = 131,3 dB

burp 65hz = 134,4 dB

burp 60hz = 137,9 dB

burp 55hz = 138,4 dB

diameter 13cm, length 27cm, theoretical accord 55hz :

burp 73hz = 130,9 dB

burp 60hz = 139,9 dB

burp 55hz = 141,1 dB

diameter 13cm, length 36cm, theoretical accord 50hz :

burp 73hz = 129,6 dB

burp 60hz = 140,1 dB

burp 55hz = 141,2 dB

diameter 10cm, length 14cm, theoretical accord 55hz :

burp 60hz = 135,7 dB

diameter 10cm, length 5cm, theoretical accord 69hz :

burp 73hz = 127,0 dB

burp 60hz = 133,1 dB

as noted, I tried all the tubes, but the results do not change much ..

looking at the results, what can you tell me?

These are two photos of the hood, box and batteries should go in the boot, while the amplifier is attached to the back turned

[sundownz 197]

The problem is phasing of port to woofer cone. It would be ideal for SPL for the woofers to face forward and the port backward.

Can you fold down the seats for SPL and do this ?

[kkk4 3]

ie?

subwoofers facing forward, toward the dashboard

and the tube facing the back door?

so mean?
