[QUOTE="Ivan Beaver, post: 55846, member: 30"] Re: Subs Subs Subs That is a VERY important point-and also applies to ANY sub that uses a boost on the bottom to get a lower spec sheet number. Yes the response at low levels wil be flatter and lower-but as you go up in level, the MAXIMUM output will suffer. You simply will not be able to get the same SPL at higher levels. If you put a 6-9dB (not untypical) boost on the bottom- you HAVE to subtract that same level from the max SPL spec-assuming you still want a flat response at the louder levels. You simple can't put a boost and then keep turning it up the same amount. It doesn't work that way. As I often say-DO THE MATH- PEOPLE! Once people actually start to put a few numbers together-read a few response graphs (I am AMAZED at how many people cannot understand a simple graph-such as freq response-amplitude vs freq), then they will start to actually understand products and see how much "marketing" there is out there. Yeah-Iknow-that requires a little bit of effort-and now a days people just want other people to tell them. And as a result they just blindly follow along with whatever the manufacturer tells them-whether it is the truth or not. I do like the fact that on Bag Ends website they state (somewhere-I don't remember) that you won't be able to hear or feel the 8Hz response-but that doesn't keep people from blindly stating that their subs go to 8Hz!!!!!!!!! Yeah-and my tweeters will do 1hz with NO PROBLEM AT ALL. Now You won't be able to hear it-but you can put a 1 Hz tone into them and watch them move up and down at a 1Hz rate. So they ARE reproducing that freq. Not at any usable level-but they ARE reproducing it. So every loudspeaker made could make a 1Hz claim. The REAL question is how LOUD is it at 1Hz? Once you start to question THAT-THEN you start to understand. Getting off my soapbox now. I've got a demo in the desert to get ready for. High temp and low humidity and nothing in the way-let's see har far we can actually get some highs out there with a "super tweeter". [/QUOTE]
