My local audio retailer, that I bought all of my stuff from, for years, always said "You don't need a subwoofer." Yeah, right.
I was driven to purchase a Velodyne subwoofer when my old Integrated Amp started failing. It would go into shutdown at the most inopportune times and after swapping out 2 different sets of KEF tweeters, I decided I needed a subwoofer.
What a wonderful addition. Now, if I had PMC's or some other high end speaker system, I may not have needed a sub. With my KEF Q70's, the Velodyne allowed me to tailor the sound to what I like. I can get room shaking bass, if that's what I want. I've gone for a more balanced sound that works well with CD's such as Telarc's "Time Warp", "Round Up", "Star Tracks II" and others as well as Rock and Roll and Jazz.
Yes, it took me weeks and hours and hours to get my crossover point and the gain levels along with polarity and phase set. I'm sure it drove my wife nuts while I was tweaking it.
Now, I'm real happy with it.
Classical music covers hundreds of years of music. There are large Orchestral works and small Orchestral works along with Sting quartets, quintets along with woodwind or brass quintets or even Wind Orchestras or band pieces. All can have varying instrumentation.
There are a number of classical "starter" lists on what to listen to. Start out slow and listen to a variety of works to figure out what you like. Telarc recorded CDs are some of my favorites for cleanliness of the recording.
Sometimes, I have to pick a CD based on the Orchestra performance over the technical merits of the recording.
I'm sure many people would disagree about some of the recordings that I like from a technical standpoint and some of the performances that I think are great.
Listen to samples, decide what you like and build your collection.
