LE14H-1s. If you want to bring the PT800s by, some night, that would be fine. I'm bi-amping the XPLs, so the PT800s and FS400s would work perfectly together in my system with no changes. Plug and play.

Your place or mine... I'm also bi-amping the XPL's. 'Stll need to decide on a crossover for the PT800's...

I'm going to guess that the PTs are smaller and lighter than the FSs, so bring em over.

[Zilch]

Bring 'em HERE first, John.

(4430's, XPL200A's, or PT800's w/subs).

John

That's how I'd order them. Now the question is, ascending or descending?

[MJC]

Not until I get some decent subs hooked up to them...

John

Maybe you can talk Mr. Widget into selling you a pair of his sub1500s.
They work well with PT800s
It would seem that JBL doesn't have any PS1400s

I've already got a spare pair of Sub1500's. First, I'm going to try a pair of freshly refoamed LE14A's, since I don't need a huge amount of sub in the room they're in.

I have a question for PS1400 users. Anyone notice a slight buzzing or humm from the PS1400's plate amps? If so, has anyone attempted a cure. I tried a PS Audio UPC-200 and no change. I was thinking about applying damping material to the transformer/torroid, but that would require surgery. Anyone?

BTW, the noise is only audible when I am within approximately six feet of the PS1400's, and is the same out of both units.

[JuniorJBL]

unplug the signal cable and see if the noise goes away.

[maabx]

I tried that but no change. The noise sounds mechanical, like a transformer buzz.

[Titanium Dome]

I've not heard that from my three PS1400s. However, one of them does sound like a dynamo is revving up when I turn it on--a teeny, tiny dynamo.

Since I usually leave them on full time, this is rare, but if I turn it off for some reason, when I power it back up, there's a very slight, rising sound for about seven seconds that sounds like the world's smallest engine is revving, then it disappears. :dont-know

I've not heard that "slight buzzing or humm" sound out of mine.

However, I have the same revving sound Dome mentioned; kinda cool really. Let's me know their up and ready for business.

[maabx]

You may be able to hear it if you put your ear to one of the ports. Mine are on Auto full time.

[porschedpm]

No buzz out of mine. You might try changing electrical outlets so that you end up o a different circuit breaker. Sometimes noises from refrigerators, furnaces, or AC motors can bleed through.

[maabx]

Thanks for the suggestion. My audio is already on a dedicated circuit. There is no video on the circuit, the PT800/PS1400 stacks are being used for two channel audio.

So all of your units are completely silent in standby? The buzz I have is more 'detected' than 'heard'. You would have to be very close to the units in an otherwise quiet roon to hear the low level buzzz/hum. There is no mistaking it when I put an ear to one of the ports on each of the units. About the same level of buzz on both units.

I am a huge fan of these speakers and I will be keeping them for the next thirty years. The noise will not keep me from enjoying the speakers, as I cannot hear the buzzing from my listening position. But you know how it is: because I know that it's buzzing, I want to fix it.

[Titanium Dome]

Just to be sure, I got behind the units and put my ear right on the cabinet--nothing. Except now I need to dust the cabinets.
