Default Buying Subwoofer driver-help

I am looking to build a subwoofer, there are 2 subs on sale at the moment ,

1. Shiva from DIYcable on sale
2. M&K 12" from Ebay at this site:

http://cgi.ebay.com/M-K-Miller-and-K...=1218796148715


I don't know very much about subwoofer, any suggestions and recommendations are welcome.

thanks in advance.

don't buy it now.

Go and read about Linkwitz transforms. i.e. how to EQ a sealed box driver to get bass out of it below Fbox.

This needs high power and high Xmax and high power handling and if you ask for more than 12dB of low frequency boost you end up with a poor bass speaker. 18 to 20dB of boost looks impressive on the graphs but it does not work effectively.

Hi ttan 98; you can't buy direct from DIY Cable because he has a marketing agreement with Audio Marketplace, you would have to get a third party to purchase for you and then re-send to you in Melbourne, two sets of postage costs.

I may just do that, I know someone who can buy on my behalf.

There could be another possibility, Lorantz are made in Australia, I believe that there main market is for "PRO" drivers but if we could demonstrate the market and put in a bulk purchase order perhaps we could get a subwoofer driver built to equal the performance of the "Shiva" or Tempest"

We'd need to organise a big group of people, and find out what the minimum production run was.
I have been contemplating buying a pair of Tempest sub drivers myself but funds are very tight until I find a new job.
Regards
Ted

If you are interested in Lorantz, they are on auction TODAY, a little late on Graysonline.
