Anybody know where to buy some speaker terminal cups for a subwoofer box im building? Im after some decent quality ones, not the crappy ones on ebay....

Also, does anybody know how much power can go through most terminal cups?? Ive heard that they can melt??
Cheeerss

Just go to Alberts or something man

I just bought one from Jaycar myself a few weeks ago. Cost me a whole $2.49 or something like that. I think they had a few different size/shape ones to choose from there too.

P.S - Never heard of them melting. Unless you have some crazy crazy amps driving the subs, I wouldn't worry about it, the smallest one should do the job fine

Its a Secwet :P.... Just 1 sub thoughh.... Buying it on thursday so you'll find out soon enough... ;)

With the speaker cups, I am not sure how you are going to build your enclosure ( dual 18mm I hope ), but if you think about all that pressure, thick walls and a waffer thin plastic holder - not good.

If you would like one for aesthetic reasons, mount it normally on the outside but also put some mdf on the inside covering the entire plastic area. For the speaker wire, drill a small hole to feed it through and seal around it with silicone. Once that is mounted it will look good plus I wouldn't fear it leaking ( I had one do this with a Boston G5 + 600WRMS sealed after a couple of months ). A 2000WRMS woofer is going to put a lot of stress on any box.

Went down to a few audio shops and all they had were dodgy cheapo plastic cups, so I decided not to use plastic cups. I bought 2 sets of these off ebay http://i8.ebayimg.com/03/i/05/e9/62/ef_2.JPG, and hopefully these will be ok. I am gonna make them fit as tightly as I can, and also cover the inside of them will sillicon when the wires have been hookup up. I will then be using banana plugs to connect to the amp (Didnt know if banana plugs were good for connectivity or whatever, but they are so easy to plug in and look awesome so I decided to get some..)
Im also using 1" mdf and using a double layer on the front (And bracing on the inside) so hopefully this will be enough?

Yeah it all depends on the length of the walls and what bracing you have.

25mm should be the go!

Just gotta make sure that no air can leak out of them - bit hard until it is all up and running!

Sweeet! :D
Yeah, Im hoping because they have a thread that I can drill a pilot hole and then thread them through. This should create a pretty air tight seal by itself im hoping. The fibreglass resin and sillicon caulk stuff should keep it airtight tho.
Is there any way to check if its leaking when its up and running? (Other than putting your hand infront of it and feeling for air)?

Ill upload a pic when Ive done all of my bracing and hopefully you guys can tell me if Ive done it right/wrong.. :)

Are you running it sealed?

If so, it will make a loud sound that you will definitely notice if it is leaking - even at low volume. Just run your ear around the box :D

Yeah, box is sealed. Cheers man! Will definately do this check when its all up and running!

ha I was hoping you were not going to do something as sac-religious as porting a XXX. :D

Don't worry you will notice, I have my 10inch Polk sealed and 2 of the screws were leaking ( temporary screws until my grill came with flat HEX screws ) so I siliconed them up - worked fine with no leaks until they were replaced :D

Yeah ahhaa, well ive been told that they dont sound all that great in a ported box.. plus it works out well for me as a ported box of recommended size probably wouldnt even fit in my boot!...

Ahh sweet! , Cheers man
