hi guys, sorry if im posting this in wrong area. please move if it is.

well, im thinking of getting a custom box made for me. nothing special. probably a bandpass for an 8" inch sub. no plexiglass. just a simple box and carpeted.

it to be specifically made for a sub that ill be picking out first.

i found a local guy that says he can make it for me but im not sure what a custom box goes for now a days.
how much should i be paying for the the custom box?

thanks for the reply, i was waiting for someone to post this (statement) as it seems like a recurring theme with most posts on this forum. lol

i cant do it for a few reasons and here are some; dont have the time, no tools, no place to do it at, not enough experience.

so, again what should i be paying for this?

It all depends on the quality and level of service you would be receiving, personally if there gonna be using a generic design I wouldn't pay more then 80$ If you go and have a design done for the 8" sub and its something a litle more complex id say 100-120$ I build my own boxes so these numbers are more of how id value someones elses work for me.

I myself wouldnt pay over $160,thats a real custom made box ..wrapped, ported, tuned,and good MDF of 3/4,and routered for the sub to sit flush with the box..for an 8, that for me would be a fair price

Price will change and is more subject to who is building it. Some times the cheaper the price there is a reason. In most cases you do get what you pay for, but in some cases like shops that is not the case. They will over charge you many times and still not get the results you want. Some shops do a great job though....

So to be honest, it is a roll of the dice. Our prices are pretty standard, but we don't list band pass pricing as those prices can change with a simple alteration of how the port is setup...simply to many variables to consider when shopping for enclosures.

I would expect to pay $100+

Please know that not all subs work well with band pass enclosures, you should work with whoever will be designing and building the enclosure to make sure you get the right sub for the job. (Also, ask how they design the enclosure. Using rule of thumb or just guessing will not work well normally)

im limited on space.
i currently have a 12 incher i would love to use but the builder said that it would need a certain dimension that i do not want at the moment. so just something nice, loud, clean, that has a very small foot print.

what questions should i ask?

Band pass is often bigger than a ported box for the same sub. As far as what you should ask- how do you design a BP box? What program do you use? How does it compare to a ported or sealed box for that sub? What is the frequency response of the BP? ... You don't need to ask all these things, just try to see if he knows what he is doing.

so what would you charge for something like this with maybe rounded edges and carpeting. estimate is ok too. (4th order) and maybe (6th order). just curious what it would run on either cost.

You were wanting the most output from a bandpass type box. I should have said "Isobaric 4th order series tuned bandpass" The isobaric loaded 4th order bandpass has 2 subs that are mounted face to face on either side if the internal baffle. One sub is wired out of phase with the other, as one cone moves outward, the other moves inward. Essentially creating a box that handles twice the power and 2 drivers doing the work of one sharing the same airspace.

This is not a good idea for the SA8. Isobaric loading allows you to use a box half the size of just one sub, but you don't gain any spl by doing so. And the box is so small with just one driver in it that it might not fit.

FWIW Ported is smaller than any band pass box for the sa8. And a 4th order bp will have less output. You can get more output with a 6th order bp, but it is bigger (1.2cf in my model) And now you can use a SA-12 in a box about the same size and get the same spl and more head room.

not looking for bigger guys. just looking to see what i need to pay for an 8" inch band pass box. quality and built right for a specific speaker. ... and looks good too, simple look.

no special painting, no special designs, no extra swirlies squirrelies, no wierd shapes, no "lets bump up the sizs to a 10 inch, 12 inch or 15 inch" , etc.

just pricing on a carpeted box that looks like it was made with quality and sounds amazing.

thanks for explaining that. so i would need to get a second sub to make that order work. well i guess not then because i want to just make a single sub work like it has never worked before. a single 8 inch sub would just be perfect for me

People are suggesting a larger sub because a 8" sub in a bandpass will most likely take up around the same space as a ported 10". Basically, you will have better output and take up the same amount, or less space with a larger subwoofer. A 4th order is not a good option for space saving. You could probably do 2 8s in an aeroported enclosure in roughly the same airspace as the 4th order.

Obviously you see the smaller footprint advantage of the 4th order bandpass isobaric loading, which can be done with 2 8" subs that are cheaper in cost combined than the sa 8 without loss in sq.

This is very true. Very few builders/designers ever take anything other then... "this will work" into consideration when building and designing your enclosure. Now remember it will work..but there is more then likely a better or more efficient way of getting it done. In other words, you are more then likely not getting your maximum performance out of that application.



As for our pricing, typically for BP applications I put a bit of time in it for free to get a "rough" idea on the design then offer out a quote. That way we are all on the same page and expect the same results and look.

I would need more information and then I would have to put some time into a rough design in order to offer a price for the work. It is not as easy as just tossing out numbers do to the vast number of factors. Some BP enclosures are fairly simple to build while others are more difficult and require more time for assembly.

hey thanks guys for the reply but..
there seems to be some confusion . the order of requirement is in the wrong direction. im looking for a bandpass this time for my box. but i would like it be the smallest version of a bandpass. i dont want a sealed or just a ported version. i would like to try out a bandpass this time.

kinda of like when a person wants to eat ribs but everyone keeps saying to eat steak, eat steak its better just put some bbq sauce on it, or eat chicken and put bbq sauce on it, but my preference is that i want ribs this time around.

....again what price should i be paying for such a small job?

If the OP does not need my post what did it hurt? it might not be relevant to you but might be relevant to others, for example if somebody can build me a custom box for 2 15"s slot ported $140, bandpass box for an 8" does not require that much material compared to a slot vent ported dual 15s. probably more work needs to be done on bandpass, but at least he can weight it. less material more work etc..

lol...aside from the suggestion of doing the PR design with the sub you wished to use, every suggestion I have made has been towards the most compact bandpass design. The issue is finding the driver(s) suited best for the box design you choose.

Materials to build a box are cheap this isn't new experience craftsmanship and labor cost is what you pay for there's a local who builds more boxes than I do monthly however I have seen his boxes and they are trash he charges about $20 less than me and I. Will not budge on my prices a 2-15 slot ported box from me would run $235 plus shipping to start as it would take 2 sheets of wood and lots of my time .

please explain if you could how to make it sound clean. im looking for less of a punch sound but more of bass that carries for the 8 incher? if im even making any sense.


how bad will it hurt the sound if i wanted to add a plexiglass at the front to see the woofer?

the design has never really taken off in car audio,IMO, due to the complex design for the DIY(and space req.). There are still one or two companies that have been manufacturing quality Bandpass designs for decades.

I agree and Toby has some great enclosures. While they come pre-loaded they are still great overall. His are designed with efficiency in mind so there is no need for a lot of power in order to have a good level of "loudness".

And for those who don't know..he was the first to use those kind of ports...not other designers/builders who take the credit for it.

the sound quality will be the same with or without plexi, as long as the plexi is thick enough not to flex. I am confident with pro-rabbit it will be structurally sound.

with this small box what would normally be used?
how many inches thick?

also what size thickness is available out there?

actually, as I understand, Lexan is stiffer than plexi. In Lexan, 1/2" thick should be fine for the small window you intend, In acrylic, or plexiglass, 3/4" material. I am not a builder, I am just going by the few windows and boxes I have seen. If you choose a good builder, they will probably be able to be more specific on this than I.

i got a quote back from the guy who is local to me.

tell me what you all think about him and should i go with him?

"I only use a port length calculator everything else i manually calculate with the dimensions given to me. for a standard bandpass enclosure i charge 240 without carpet since its a single 8 inch enclosure, i'll do it for 200 without carpet. I guarantee my work or your money back."

also it was quoted with no plexi.

2 bills is not bad if it is what ur looking for, you are confident it will be quality and will perform as expected, and the builder is reputable
