I want to try and keep the passive crossover system if possible for the IV's.
Here is the original question with a Rabbit reply. Thank you, this is a good start.
Post subject: Re: Let's get this site back to talking about Carver
OK, here is some carver talk.
Has anyone here ever modified the plat IV crossover to cut at 180 to 200Hz? Is this a good idea? Will the plat IV subs handle the frequencies to 200 well? Will it upset the balance of the sweet and juicy like these nutz. sound these speakers produce?
I am prepared to do the surgery to extend the longevity of the ribbons. I would also be open to a mod for a bi amp option. Pics and plans would be appreciated. I am picking up a set of Plat IV crossovers this weekend for the potential mod process.
--Clearview actually made active xovers to specifically replace the Carver passive xovers, and if memory serves they DID cross over at 200 hz to take some pressure off the ribbons. SO, I guess the woofers would be up to handling the 200 hz signals....dunno. Maybe James can say for sure....
Also, has anyone ever modded a set of AL-III's to use a sealed sub enclosure? Any crossover changes? What driver was used? What is the volume of the cabinet?
--I've talked about & considered this, but was afraid I'd mess up the good job Bob did with them...if you were actively bi-amping & had a sinewave generator & decibel meter, you could probably make it happen. I use Infinity Perfect 10.1 (automobile apps) subs on my AL-IIIs and love them. The box volume on the AL-IIIs is APPROXIMATELY 1.8 cubic feet.
THERE IS NOTHING WRONG WITH OPERA !!! I listen to it at the shop I even have some on LP.--There are a couple of Operas I like to listen to....
