I'm irritated that I have to build full passive 4345 filters...
Well a few years ago before they were talked up on this forum I knew of at least 3 pairs that sold for well under $2000 in nice shape. But that was then and this is now. same thing with the L300.

FYI, here's the other end of the price range: http://cgi.ebay.com/ws/eBayISAPI.dll...m=180455959038Well a few years ago before they were talked up on this forum I knew of at least 3 pairs that sold for well under $2000 in nice shape. But that was then and this is now.
But what's the point in that - get a nice fat amp for the woofers
and just passive the other 3 drivers!
Its the way God intended it, it must be right!
Even with my little bitty '41s and the original crossovers
I can hear the difference with the woofs on a solo amp.
The few times I've had hardware issues and dropped back
to single amp mode its been a sad sound by comparison.
Can't even imagine smothering 18s that way ...
2ch: WiiM Pro; Topping E30 II DAC; Oppo, Acurus RL-11, Acurus A200, JBL Dynamics Project - Offline: L212-TwinStack, VonSchweikert VR-4

Evidently 90% of the 4345 owners can because they want 4-way passive networks with the damn switch...
I don't understand the resistance to biamp them either. It makes so much sense to biamp them. Not like it's all that hard to do.

Yeah, I thought Greg explained it pretty well. Maybe folks simply want to try it passive first for themselves. I could sort of understand it, if they have had limited multi-amping experience.I don't understand the resistance to biamp them either. It makes so much sense to biamp them.

Yeah, but you have a JBL DX-1.
The affordable and popular Ashly XR-1001 is a tolerable unit, but unless you are running a nightclub, or want that type of sound it is very difficult to find an active crossover that will live up to the hypocratic oath. Even though lesser active crossovers will give you the benefits of being able to select a big ballsy amp for the bottom connecting it directly to the woofer and using a smaller more nuanced amp for the rest of the system, most crossovers typically impart a signature all their own on top of your system.
As for difficulty of set up, biamping with only the one crossover point is usually manageable for most people even if their only test equipment is their own pair of ears... going into additional active crossover points becomes rather difficult to do by ear though.

I think it might be a language barrier issue.I just figured the guys running the 4355's could tell the guys running the 4345's what active crossovers to use.
FWIW, on the high pass side of things, I have been experimenting with a first order passive (a pair of single capacitors in the balanced lines at the amp inputs) using one of my preferred boutique caps, Multicap RTX, versus my active fourth order Marchand (w/premium op-amps) lately.
Other than the weirdness of the widely differing roll off rates, the sonics weren't too bad from the active unit. Kudos to Marchand.
I agree though, I would never use my Ashly's for high pass use in a high quality application. I do use them on the bottom, though.

On a side note, I would like to personally welcome "tjnif". I just sent him a PM because I would know those initials anywhere...it has been about 8 years now since my purchase from you.
I did not know you were a JBL guy...
He is a GREAT guy. Welcome.
Despite the all original blather, the 2245Hs have waffle surrounds.
And yes, welcome, tjnif.

Too many audiophiles listen with their eyes instead of their ears
Hi, Clark...
Define "waffle"...? 2245H's are with foam surrounds, if that's what you meant.
Dude,
Them woofers ain't as they were made.
Uh-oh...
I see now - I could not see that on my Droid. That auction is rife with misrepresentations!
