Subwoofer for Vintage ADS 200 Speakers?

Just got my hands on a spec sheet for the ADS 200, 300 and 400. The 200 is rated to 85 HZ. Should be fun.

You can't beat that! Go for it!

I am not sure it goes below 100 HZ either. I have not found any specs on the ADS anywhere. It does have a 4" woofer perhaps like the one in the less expensive Minimus 7 rival at the time. The Minimus 7 specs go down to 50 HZ. http://support.radioshack.com/support_audio/doc31/31593.htm

Looking strongly at the Martin Logan Dynamo 300 sub. It can be had for $130.

I doubt that speaker goes below 100 HZ. Take a look at the
Parts Express site,they have a few Dayton Audio powered subs
below your $200 budget that should blend nice with the ADS
200. BTW that is a great little speaker.
