sub box prices

[Sabby]

i made a dual 12 inch sub box, carpeted.
i was jus wondering, if i try and sell it, how much shud i be asking?
it cost me 70 to make.
it weighs 20kgs and dimensions are 900mm x 500mm x 400 approx.
im thinking around the $90 mark?

[Tasmaniak]

Are you a professional carpenter or cabinet maker? If not, then your asking way too much.

i been doing carpentry at school for 2 years and i had the help of my uncle who is a carpenter.
the box took me 10 hours to make.

[Burnout_bro]

you will probly get 60 bucks max, bought mine brand new for 160 and that was a custom made perspex one.

[wrx884]

yer deffinatly not $90 prolly wat burnout bro said u wont make ne money off it unless u r a cabinetmaker/carpenter as they will add their labour costs 2 make it thats y they will b able 2 sell it 4 more not 4 the box itself u can buy duel prefabed boxes 4 around $120 new

But in sayin all that if ppl r willin 2 pay $90 then go 4 it hahaha

i learnt my lesson years ago with buying sub boxes when i knew nothing about car audio........never buy them......always make em yourself.......i made a 71 litre 91mm (port diameter) ported 16MM thick MDF box for my JL W3 V3...........best thing i ever did........i pull MONSTER bass from that single 12" sub all because of the box........i have tried it in smaller boxes and it sounds ok but not as good..........my point is.........nothing really...........it has nothing to do with what you posted really........ill shuttup now

yeah i agree, coz u no wat u want.
i used thick MDF to, works a treat. wiehgs a bit tho.
what do u rekon is better? sealed box or ported?
i have a 12 inch cadence sub, with a smallish porthole in the box.
bigger port hole = ?
smaller port hole = ?

[Burnout_bro]

ported boxes need to be big

depends what wattage is your sub? the jl 12.5" i have is 300watts rms.....i have it hooked to a 350 watt monoblock with the gains down......i have the 91mm diameter PVC piping port...........works wonders.......

[Cobez]

ported boxes need to be big

not all the time...........if you have an 8" or 10" single sub you dont need a huge monster box...........or big ports for that matter..........

[Sabby]

ah, well i have a 12 inch sub in a box. i think the sub is around 350wrms mark. i had the box sealed and yesterday put a 91mm PVC pipe port in.
my results were:
pre- ported, wen boot was open, sound traveled alot further
ported, was a bit deeper in bass but sound didnt travel far

[Cobez]

is your box home made or did u buy it? and make sure the sub cone is facing towards the back of your car as if it was looking out the back of your boot behind you..........this makes alot of difference.......and if the box is home made then it would have been built to sealed specifications........you need to make another box to ported specifications

[James_yo7]

id pay 90 for it if it was very well made

[Sabby]

heres a pic, jus to get an idea

[Tasmaniak]

no I wouldn't pay $90 for that.

The carpeting work isn't of good quality and the box leaks like a mofo.

[JBDrifter]

ah, well i have a 12 inch sub in a box. i think the sub is around 400 - 500wrms mark. i had the box sealed and yesterday put a 91mm PVC pipe port in.
my results were:
pre- ported, wen boot was open, sound traveled alot further
ported, was a bit deeper in bass but sound didnt travel far

So you cut/drilled out a hole and added a port to your sealed enclosure? You do realise that the enclosure specs are different for sealed and ported right? A sealed enclosure will be much smaller than a ported enclosure for the same sub. Hence, your enclosure is now most likely too small for your sub. Your sub wont be running very efficiently, ie. could be louder and better quality.

I would recommend sealing it back up, or if you really want a ported box just start from scratch and build another one.

Depends what you want. Ported for SPL (loud!), or sealed for sound quality. You also need to consider boot space, a ported box will bigger, leaving you less boot space. If boot space is important to you then you might want to go with a sealed box.
And different port sizes will define what frequency your enclosure is tuned to. I'm not exactly sure how the tuning works, you'd have to look into that yourself (unless someone else here can explain it), but you tune your enclosure by using a specific port size. Different diametres and lengths have different results.

yeah, i was working with trail and error.
i could tell that the ported box was sh**. so i filled it back up, it sounds better
and yer boot space is an issue for me i guess.

all

no I wouldn't pay $90 for that.

that big black sub box has liquid nails all round the joints. not a single leak at.
its hard to get a good pic from my phone lol.
i got the carpet from bunnings but it has wadding around it, thats y it looks a bit dirty around it.
im not gonna sell it, jus was curious to if i was.

spot on mate spot on!!

[r_i_d_a_h]

aright just on the subject of box prices, how much would you fellas expect to pay for this box.

i made this custom box a while ago for my cousins bmw and it sat in their snuggly, im no pro- cabinet maker or anything like that, just handy with tools and got the know how about volume and stuff

each chamber is about 1.0-1.1 cubic feet exact air-space for the clarions, 18mm MDF, blue neon in chambers,16mm perspex back lol and the lil cars for show, lol it takes a fair bit of airspace but still sounded tip-top.

[Cobez]

really depends on what subs you are running........what wattage etc.....not a bad looking box though mate!!!

[wrx884]

Id like 2 see this box uncarpeted altho it looks good from the outside and in n shows u put alot of work into it but the carpet can hide alot things but if u sell it with all the accessories mayb $120? (not including subs)

[r_i_d_a_h]

lol...what can i say?..i love subz! i gta make em look guud while sound good

baaah the clarions are lyk uhmmm 300watts RMS?? 600 wat MAX??

got em for like 80bux each when they first came out..probbly only worth like i derno 30 bux now? lol i dont really care

but still how much would you guys pay just for the box itself??

[r_i_d_a_h]

um under the carpet?? about 1 19mm screw every maybe 2 1/2 inches

cant really remember those are one of the many boxes i have built and designed.

the following picture is a box built by me for my room, non fabricated so u can see how its put together...i construct the boxes exactly the same way except in this case the box is standing up

[wrx884]

Did u counter sink the screws in bout 10-15mm coz u said u used 18mm MDF 19mm screw wouldnt grab nething unless u were talkin bout the perspex? other than that definatly looks like u have a nack 2 makin these boxes u could prolly sell these better than most prefabed boxes even tho they r cheaper but these r built 2 specs and actually look strong
