I have a pair of Polk Monitor70 II's that had ample bass output for my ears. It's nothing like the sub I have now, but I thought they did pretty well for electronic music. If you have the budget, go for better speakers now, but despite all the negative comments about Polk, they're okay. The fidelity is not up to par with the higher end speakers, but like I said, they're quite enjoyable with electronic music. Go to any speakers stores, a Best Buy Magnolia, something, and just listen to whatever you can. Try and get a feel for the signature you want. A sub is your best bet for bass, but there are towers out there that will satisfy you as long as you're not expecting huge bass.
