"I should've bought one when I bought the LSR305s!"

Man! This thing is AWESOME! I should've bought one when I bought the LSR305s!I didn't because it was nearly $500 and I lived in a condo on the third floor. Now, I live in a house with ceramic tile throughout. I know quite a lot about subs for home theater and I've had a few including M&K with the 2 Push-Pull 8" and Definitive Technology Powerfield 1500. The Def Tech was $999 and I bought it while I was in Flight School. That one was awesome but like 100 lbs and sealed. The first song I heard on it was "Cherish The Day" by Sade. I was sold. This is for a totally different purpose for me, unlike the Home Theater consumer units as they are a lot more forward. I'm so glad I got a matched brand with a set crossover so I won't have to fumble with it. In a studio environment, you really don't notice the subtlety of the sub most times but, you definitely know when it's NOT there and it really offloads the power requirement for the monitors. So much more detail from the monitors as I now have a nice 3-way system, which I think should be the minimum. Now, what I have is a set of monitors with 5" lower mid-range drivers that have more room to breathe. I've never liked the trend toward 2-way near-field or regular home speakers. They are fine for college dorm rooms at restricted levels but, for serious listening and/or mixing/mastering, you have to have at least 2 crossover points. Those little woofers have to work too hard. That's why today's popular music sounds like crap and is read more so strangled. I listened to some modern music on my mother's Kenwood KL-777Ds and there was just so much missing compared to when I heard Steely Dan's "Hey Nineteen" on vinyl 40 years ago. Listening on 2-ways, the same material will sound pretty decent at low volume levels but, when it's time to raise the volume, they fall flat. That's when a great sub is required and this, for my bedroom studio, is a GREAT SUB! Now, it's time to Re-Master EVERYTHING! This is a real Game Changer!Note: As the manual states, when matched with LSRs, the volume settings should be turned up on all of them.
