Welcome to my Sub Project Website. My goal was a small in size, big on sound internally powered subwoofer for use in my apartment. Lambda Acoustics sold the best candidate for a small sealed sub. I looked at many others including the offerings from NHT, ACI, and the Titanic. But, most required a 3cu. ft box for a sealed box or required a vented alignment. The finished product will be used for music only, not home theater. I did not require ultralow response, because it would get me evicted. WARNING!! this sub is overkill for an apartment environment, but does take up a small amount of space. I also did not want to build another sub when I finally get around to purchasing a house. I hope to use this sub for years to come.
