Is it worthwhile to spend money on a subwoofer that isn't any better than your mains in terms of bass performance? I went with tower speakers in order to avoid the cost of a subwoofer for music. I don't regret my decision because they cost me no more than a similar small speaker. However, I am thinking more and more that I may have to get a sub sooner than I thought. The main reason for this is room response problems. I can understand why someone would add on a cheap subwoofer for a little extra thump in movies, but what about music? (2 channel only system as of yet.) Is this really worth it? My tower mains have excellent bass. However, my main channel positioning isn't very flexible at all since this is all in my bedroom and I do have to live in it... I think that I may end up shortly with a subwoofer that strangely enough, can't produce as much clean bass as my mains can. But if I can put it in a corner for a flatter response... and take the load off my mains to make their sound cleaner... does that make it worthwhile to buy an already obsolete product? Food for thought. I really appreciate your opinions.
