Nic,

I haven't found any source in Australia and I doubt you will find it. You can get it from Parts Express, but expect to wait 3 months unless you are prepared to pay for air freight. I think the Titanic driver will cost you about $380 IIRC. On the other hand, you can get the Shiva here in Oz for $300 or if you are clever you can get the Peerless XLS for $220, both worth considering.

regards,
Paul

You really don't need a kit to build a subwoofer. They are very simple. Get a plate amp, a good driver, choose and alignment, build a box. Copy a similar sub if you like, it is quite easy. Not like full range speakers where you need to design a crossover.

What are your goals?

I can show you a few examples. You can use other drivers (as I have), but you will have to pay for shipping and wait 3 months for them to arrive

cheers,
Paul

You are in Australia, right?

If so, start with drivers you can get here!

It's hard to make suggestions without knowing your goals? Output, extension, music/HT etc

regards,
Paul

Its for Home Theatre. I like tight bass, not boomy, I want a sealed enclosure. I am going to have a system with 6.5" main and centre speakers.

Nic,

I'll make a few suggestions, based on drivers you can get in Australia.

Peerless XLS - a very good driver used in quite a few comercial subwoofers, as well as DIY projects. There are two good examples of sealed subwoofers using this driver, with good info.

http://members.ozemail.com.au/~joeras/sub_index.htm

Linkwitz has also made a similar sub:

http://www.linkwitzlab.com/thor-intro.htm

This driver is generally best sealed or with a passive radiator. It is very difficult to design a vented box for this driver. Here is a passive radiator version:

http://www.geocities.com/adrian_mack/

or there is the Shiva, which is a little more flexible in that it is easier to design a vented alignment with the Shiva. The Shiva does tend to need a bigger box, but it has a balance of parameters that is preferred by many.

I see no reason to so quickly jump to a sealed sub if the application is home theatre. You give up at least 6db of output and considerable bass extension which will reduce the impact of LFE that most want a subwoofer for in HT use. Either you are willing to give up output, or get a driver with a big xmax to get decent low frequency output in a sealed box, if you go sealed.

hope this helps,
regards,
Paul
