I have built a set of speakers based on the Nirvana Super 8's full range speakers. I like the sound, but alas, not much bass.
I will be running a small singles ended amp (think Darling, or the like), but I would like a recommendation on a good DIY subwoofer project specific to the task of adding some low frequencies to my full range speakers. Money is always a concern! hahahah. But, what is the best bang for the buck.
Yes, they are very very green.
I think the commonsenseaudio.com Nirvana drivers are a really good value. I would like to afford some 12's and a big enclosure. There would be no bass problems then.
