sub-woofer recommendation for 2.1 channel


I'm currently using Primare i21 integrated amp and Totem Model 1 Signature speakers.
Recently, I set up the speakers in Joachim's method (http://www.audiophysic.de/aufstellung/beispiel_e.html) and realized that bass is very weak. So I started to think about getting a sub-woofer that I can hook up to the Primare integrated amp.
Do you think it's a good idea to connect a sub-woofer to the 2-channel amp? If so, can you recommend an affordable one that can be a good match with the current system?
Thanks in advance.

Thanks for your recommendations on the Martin Logan subwoofer.
However, I'm not sure how I can connect the ML subwoofer to the amp.

Please take a look at the pictures of the speaker and amp.
