    Yes they need to stay there for long, at least as long as you do not have another protection system, and are confident about the whole system (amp DC, human errors on filtering or cabling, turn on/off noises of amps and other equipements, etc).
    You need such caps for the tweeter and also for any compression driver tou will use (but you would need a higher value caps for these, because they will be cut lower in frequency).
    For the voltage 100V would be more than enough, but bigger than that would not hurt either.

    If you insist on going active, and you are ready to do -lots of- measurements, I think the best two options are to add a horn on top to turn it into 4 way (a 2370 would do, but a 2397 would sure be cooler), or to replace the 2404 by a 2407.
    But then if you ultimately manage to get something as good as a 4348, you will be disappointed as you will miss that 80's sound [/QUOTE]

    I will be trying something , keep it a 3 way, replacing the 2118 mid with the 2360A horn and 2441 driver say 600 HZ to 8-10K , and of coarse 2245 subs

    yes I do have a nice pair of 4628B I like them for what they are they do well but room for Improvement , all I would need to do is lay the boxes on the side so the 2404s on on the top and mount the little horns on top and go active on the crossover / I think it could be a nice system for under a $ 1000 ea or as a $400 up grade .
    went through a lot of post for 2360As and have not seen the E145 used as upper bass ?
    lots of 2206s , has any of you 2360 owners used the E145s I like to hear your response .
    cheers Kartsmart
