Well, I got my 3.3 early this morning. I was reading my local newspaper and heard what sounded like a truck backing up. I look out my window and there was Fed EX. This meant my 3.3 was here!!!!!!! Heck, it was NOT even 8:00 am but no complaints here. Unfortunately, I was NOT able to mess w/it much due to running some errands that had to be taken care of. This afternoon, I was able to un-box my 3.3 as it came very well packaged. I placed the 3.3 exactly where I had my SVS PB12-NSD. Have not done any calibrating but just used the levels that were set for the PB12-NSD. I removed the port plug, turned the X-over off, set the power to auto, and made sure the 3.3 was set to run in MO mode. I also turned the gain/volume knob up to no more than 1/4-1/3 of the way. I preceded to listen to some of my demo cds and all I can say is : WOW!!!!!!!!!!!!!!!!!!!!!! Right out of the box the 3.3 sounded amazing. In fact, it does as advertised yet I have not even calibrated yet not to mention the gain is not even turned up much. The 3.3 has handled everything I have thrown at it thus far. I can confirm that the 3.3 is extremely musical-tight, punchy, and very articulate. Still grinning from ear to ear.
Thank you Dr. Hsu for designing such a great subwoofer. I also want to thank Peter Marcks and craigsub whom both have given me great advice and input. Oh, I also want to mention that the finish on the 3.3 is very good. The Hsu website does NOT do the 3.3 finish justice. So, if you are on the fence so to speak due to the finish just buy one. You will be glad you did I assure you.
