enough room for two SA-8's ported? will pay for design

[3onthree 10+ year member]

i have very little room to work with so i have decided to go with two 8's. the outside dimensions of the box can be no larger than 32''wide x 20''deep x 9'' tall. i want the subs and port firing up towards the convertible top area with the subs and port closer to the back seats. if this is enough space to make these subs sound good ill pay someone for an enclosure design.

PM BuckyBoy... He is personaly running SA 8s so he could help you out a lot here for sure

ok so i jumped on a calc really quick. its gonna be hard as hell to do a slot port depending on the freq. i could only get it down to 51hz safely. with enough port area. your best bet is to do aero ports.... i have a decent box drawn up for you that will fit. its tuned to 43hz. with 1.8cuft before sub and aero port displacement. so you would be looking at around 1.5 after everything

thanks for the quick responses. i just wanted to add that this is for daily use and is not for spl or competition it's just for music and i want the bass as loud as possible but still clean for any type of music. im gonna run a sundown 1000d or 1200d depending on what is reccomended so they'll be seeing 500-600watts rms each.

600 rms is a lil too much for these IN MY MIND. some ppl depending on box design can run a little more to these but you only need to put 300-400 rms to these to make them reach xmax. some people would argue with me but i like my equipment to last? just saying

^They'll take more than that.

for a regular ported box run 1cf after displacement and get as much port area as you can, they like big ports.

as for them not taking power make a good box..... my sa8's take my d9 @ 2ohm with out a single problem daily great response down to 30hz and up to 70ish (currently in a huge tapped horn)

This won't work for his application. The port will take up far to much air space.

He has 2.45 before displacements with 3/4" wood.

you may have to settle with a single sa-8 to give you the space that you need.

Aero ports can save major space.

This.

Aero ports will save the build, but you will still wind up being tuned a bit higher then you want to be.

You could go with a single SA10 perhaps.

a single sa8 need .6 cube so 2 only need 1.2 i have a box designed on a cutout if you would like it pm me

 

[Phoenix Risen 10+ year member]

build the box to those dims and run 2 24'' long 4'' aeros, that will put you right about 34 for tuning, and after all displacements you will end up around 1.8 cubes

box is to big for what power he is sending them. he needs .6 a sub, thats it

we have put 1500 to a pair in 2 cubes and they loved it, played like a champ, and come to think of it we only used a single aero.

not trying to start an argument, just going off what we have done in the past
