Speakers in my current system are Monitor Audio PL100`s which i love. Recently lack of bass drove me to buy a pair of ex dem Usher CP6371`s. Once i manhandled them into position & fired them up i was quite impressed, deep bass, easy to listen to, just the ticket i thought. Last weekend for some reason i decided to reconnect the pl100`s & realised i`d made an expensive mistake. If the ushers provided a window into the music with the pl100`s it was opened. I`ve now decided to use the ushers to fund a decent sub which i`ll also use in my home cinema system although that`s secondary to it`s musical ability. Any ideas what to shortlist & how do i go about setting it up properly? Any help appreciated.
