[B]Like everyone has suggested, get yourself a good active crossover and also consider an Epicenter.

 

I'm assuming the active crossover is going to have a low output impedance, just like a head, although I've never really played with them.

Hmmm, "high-headroom PWM", eh? Could this be a new term for "switching power supply"? Why in the hell would you use a switching power supply in an application that already has +12V DC to drop down from? In amps that's one thing (although you have to be careful of the radiated EMI) since you need some high supply rails to swing from, but in a pre-amp?! Maybe I should read this manual to see what the hype is all abooout...

 

hahaha...you need to sift through the marketing BS and get to the good stuff . This is great for evening out CDs, which is all I use it for. Most cd have different ranges in the bass spectrum and this does a great job of evening that out.

Now if you want to call it a synthesiizer that is up to you, but then I could also call most music synthesized because it goes through computer recording boards and are "tweaked" anyway . But the last time I heard a bass drum...it always had the same sound or it would not be called a bass note. So why is it that some cds do not have the same bass level or range when the same note is hit with the bass drum? Well someone in the recording studio messed with the levels and cutoff and I want that bass note back , so that I can decide what is the right amount (regardless of what a recording engineer thinks is the right amount). Unless he tunes to my environment, I want a truly flat recording...which I will never get.

Now this would also have to be a very sophisticated synthesizer or it would just be spewing out 30Hz junk all over the place. It would have to carefully understand where to put that stuff into the music or you would just have a constant 30Hz tone going through the music...that would not be good. So, you may not believe that they are truly looking for the fundementals of missing frequencies (that someone decided should not be there), but I do not see how else they could insert it into the music in the right "spots" without doing that.

But, hey, I am not trying to convince you that you need one or that the people at AudioControl are not stretching the truth or whatever. I have used it and found it to be a great addition to my systems...damn, now I have to start my install...

If you have the time (or the desire), bring a bunch of your fav cds to an audio shop and check it out, then decide for yourself. You may be pleasantly surprised...

BTW, you still need the electronic filter as this is a full spectrum device.

I have heard the epicenter in several different stereo install, and have always liked the way it sounded. Seemed to make the bass sound a little bit more "pure" and not quite as boomy. I like the sound of a crossover extremely low on a sub too, to keep the upper bass frequency's up front where they belong.

Good idea on the test. I have a cd with a bunch of tones on it kicking around somewhere. I will set this up on a bench before I begin my install and see what happens. Single tone in, single tone out hopefully .

I will do the test sometime during the next few months. It is too cold to begin the install so I have lots of time. I will drop you a note when I do it.
