Hi. Guys.
I'm still thinking about my first DIY sub.
Actually I don't have huge space, I have to consider encloser size.
and I found this item.
this is Klipsch KW-120, size is 20.25" (51.4cm) H x 17.75" (45.1cm) W x 17.75" (45.1cm) D (w/ grille)

also you can see its cutaway pic.

How about copying this encloser design?
I can increase the size of D to 21".

please advise.

TBH, I don't really like that port, it seems a bit on the small side. I absolutely hate port noise/chuffing.
thank you for reply.
Actually I have seen some review about that, there was almost positive.
Is there anyone heard that SUB?

But I think many DIY sub have same port type.

I also concern about port noise anyway.

Not to thread jack, but this is what I'm using at the moment. Absolutely no port noise, and it's a good box. I might extend the port a little for movies, it is tuned for music but is still great for movies.
Driver is an infinity BETA 15"
EDIT: and of course, this is before it is finished :p


But yes, the squarer (is that a word?) your port is, the better. a port that is 10"x5" is far better than one that is 1"x50".

Great Design.
However as I wrote first, I don't have much spot to put Sub.
so I have to find most effective port design.

If I change this Klipsch design to SEALED, how about?

Yeah, this is pretty big, 36"h x 17"w x 18"d

Hmm, I don't know, you could go sealed, but then it wont be as efficient. I'd say go for a flared aero port or two, or redesign this and flare its port. I can try and work something out for you, but not right now, tomorrow.

What is your budget for a driver and an amp?
I would like to buy dayton SA1000 Power amp.
Unit is under 300$.

Actually I'm in S.Korea, I have to think shipping and some tax.
Anyway I can pay 700$ for unit and amp.

You don't have huge space and have to consider encloser size, 20" H x 20" W x 21" D would have a net volume of about 3.4 cu.ft. Have a look at thre TRIO12 kit, it has everything you need, will produce excellent low end extention for movies, and is well within your budget.

If your goal is bass for movies you'll get more low end output with Passive Radiators in the box size you stated.
OK. I'll consider this option also. Actually I have to study about PR from first.
and now I know the PR have its own merit.

1 more question, in here the power is 220V, in this kit, the amp is 220V switchable?
I can't find any information in item page.

The trio12 is the driver i would suggest in an enclosure of that size. its hard to beat its performance for the dollar any way you look at it.
