Hey sorry to leave you hanging. If you already bought some speakers that's great. I did just come across these great Warfedale Diamond 220's for a steal on Amazon. They are usually $300. At this price you can get some stands for them too. These are 100% for the price. Wharfedale has been pumping out quality sound for decades. Don't let the 5.2" woofer fool you. They can get down pretty well. 45Hz is VERY low for a bookshelf speaker.
