Hello. I'm not entirely new to this hobby, but now as a homeowner I am finally beginning to build a more (audiophiley) system. I currently have an arcam a70 receiver powering sonus faber domus concertino speakers. I love the new setup, but alas, when listening to hip-hop or electronic music there is a missing piece. You guessed it....bass. I knew this getting into it when I bought these speakers. They're small...and cheap (in the audiophile world)....but it's the best I could do for now. I am considering adding a subwoofer.

Does anyone have an opinion?
To sub or not to sub?
Can anyone recommend a good musical subwoofer? I do not want the bass to overpower the beautiful atmospheric highs and 3d stereo imaging I have going for me. I use this for television and movies...but I do not like the 5.1 surround sound thing. The purpose of this system is MUSIC. TV is secondary.

Thanks for any help you can provide. Keep in mind my budget is not huge...something that fits with this system is what I am looking for.

Thanks, Matt
