Default I want to install a new woofer driver into my old broken speaker.

My current speakers are the AIWA SC-51. I recently fired one of woofer drive by my Gainclone. I hope to get some idea on fixing the speaker, cuz I don't want to waste the housing. Which low buget drive will you guys pefer? Can I buy the car's one and fit into the hole? I hope to find the stuffs I need in local Milpitas,CA. Will it be cheaper to just order it online? Is it nessery to change the tweeter too? Are they suppose to be cooperating to each other?

Default Re: I want to install a new woofer driver into my old broken speaker.

we'll need more detail if we are to help....

box size, woofer size, sensitivity, picture of woofer, XO specifics... you can't just fit a driver that physically fits, you want to get one that is at least close (and you'll need to get 2, unless you luck out and find an exact replacement)

Ok,
first, the size of the box: X:210mm , Y:330mm , Z:220mm
second, the circle hole diameter is 145mm + the screw place 10mm = 155mm. ( If I just measure the woofer is 160mm and about 70-75 depth)
Third, the specification of that woofer drive: Imp-8 Ohm, Max-35W , Min-10W. ( but box label said Music POWER 35W, NORMAL POWER 25W 8Ohm) I don't have the sensitive thou.

Anyone know chinese what this mean? Simipify Chinese Ӧ20-80

Just for the heck of it, do you see a hole in the box? Maybe an inch or more in diameter?

If so, can you tell us the diameter, plus how long does any duct located behind the opening extend?

this is what I mean http://hk.geocities.com/solomon_choi/Speaker.html The 5" one may be kinda like in the between.

W5-576S,W5-704,and W5-610S will be the one. But which one will be close to the original one?

edit: Also the new W5-820 and the W5-704 on the "New" page.

SC:

I would disagree slightly with Navin. I am trying to figure out how your enclosure is constructed, in order to figure out if the speakers Navin recommended will work well in the box. So far, assuming " building material, we know that the interior volume of the box is 0.4 Ft, or 11 liters.

If you can tell me if there is a hole in the box, (which your picture seems to indicate there is), the diameter of the hole, and the length of any ducts behind the hole, the picture will become much clearer if Navin's recommended speakers are a good idea.

The hole and duct tune the box to a certain frequency, you see. The volume of the box, which you have given us, provides us with important information which, when combined with the information about the port, can draw a clearer picture about how well your speaker will work in this box.

By the way, Tangband speakers are available at Parts Express for very good prices.

Sorry, kelticwizard. Since my English ain't that good, I really don't understand what you mean by ducts. I know it mean some sorce of tunnel or something by using dictionary, but what is it apply to speaker? The XYZ Volume of the hole? The wire? I already took out the drive so there is definitely a hole.

I want to install a new woofer driver into my old broken speaker.
SC:

There are two basic ways to build speaker enclosures.

One way is to put it in a closed box. There are no openings in this box except the cut outs for the speakers. This is a good way to build a speaker enclosure.

The second good way is to put a hole, or vent, in the speaker box. This hole, or vent, can be from one inch to four inch diameter or more, and there can be two of them as well. Believe it or not, this changes the way the speaker plays.

This vent will frequently have a pipe or tube behind it. That is to say, inside the box will be a plastic pipe, connected to one of the walls that is open to the outside.

If you have this type of speaker, what is the diameter of the hole, and what is the length of the pipe?

The pipe can also be an unusual shape besides round. I have an Aiwa speaker that has two half-moon shaped vents. But please tell me if you have a vent or pipe at all in your speaker, or the only holes in it are for where the speakers go into.

A vented or ported speaker is illustrated below. It has a big speaker, (woofer), a small speaker, (tweeter), and a vent. The dark green thing is the vent, pipe or "duct" I was talking about. Do you have anything like that?

The vent-or opening, can also be in the back. It makes no difference if it is. Many speakers are built with the vent in the back.
