I love those meters on the Carver.Reminds me of a Technics unit I lusted for back in the 80's
Is the 500T an 80's vintage?
The guts of my lastest project.An Active crossover
Where are you placing it in the rig? (e.g. between pre & amp, amp and speaks/woofer, etc)
Very cool. One day I would like to tri amp my 1.2 TLs.

Be careful hooking that third amp to those passive radiators..............;)

Passive radiators are just passive...............they are acting as a tuned port. They have no voice coil or magnet to power and simply move in and out from the pressure of the mid woofers. Pull one out of the cabinet and you will be surprised how simple they are. It is just a basket, a plywood board and woofer surround.
The bottom binding posts are mid woofer posts.
Very cool. One day I would like to tri amp my 1.2 TLs. I am currently going to biamp them but I just haven't decided what amp I want to use on the high freq. I also asked a question is the threads about using a crossover between my pre and amp. I got mixed opinions. Please let me know how you make out with yours.
I was finally able to try the new active crossover on the weekend and I will say that it is big improvement over the passive one it replaces.
If you wanted to add an active crossover between preamp and amp you would need to remove the passive one built into the speaker.But there is a good chance the change will not be for the better.There are several factors that are involved in doing this that must be considered if it is to be an improvement.If done correctly some big improvements can be expected.
I'm glad to hear you were able to improve your system DIY STYLE!!!.
I, however, am confused, how is an active crossover between my Spectral preamp and my two Adcom mono blocks seen by the 1.2 TL's passive crossover?
Thought that this article would be able to explain it better than I could.

Yes it is a bit technical but informative.
Basically you use either a passive or an active crossover but not both.The speaker with a passive network should get a full range signal from the amp so that it can do its job of dividing the bass from the treble.
Then it routes the bass to the woofers and the treble to the tweeters.If you put an active unit between the preamp and amp it does the frequency dividing before it gets to the amp and speaker.If a passive network is still in the speaker than you will get some unpredictable frequency response errors.
