JBL Performance Series

[4313B]

I think you got it.

Here's the Owner's Manual

The only schematic I've seen is of the PT800 itself ( looked simply enough) so I'm missing how they dock and what's inside the 1400. Do you have that?

PS1400 Passive Network is switchable using #2 in image 2.

Giskard:

10-4..... thanks for the info , I'll look it over and try to understand more deeply, so I can talk to you more intelligently

[4313B]

Hmm, that sounds scary...
In a similar tone as to something a friend of yours posted on another forum site...

In any case, you're welcome.

[JBLnsince1959]

Hmm, that sounds scary...

Yes, be afraid....be very afraid.....

[4313B]

Ok!

I like scary! I grew up on Creature Features.

Enough of this loudspeaker garbage. One of my favorite vampire hunters.

How did she keep her hair so full of body in those damp Transylvanian fogs and rains?

It's almost like asking "How doe JBL keep those eight-sided cabinets aligned during assembly?" or "How does JBL make that vinyl covering fit so well at the seams?"

Just like Kate trying to do her own hair, can you imagine trying to build a PT800 cab? Seems like crossover mods would be easy by comparison.

I've got a 1912 wooden Bon Bon pail that's designed similarly, with the additional complexity of the staves being narrower at the bottom than at the top. In the 40 or so years I've owned it, I've never been able to get it perfectly aligned, even with the assistance of the external hoops and the rabbeted bottom panel

The PT800 enclosure would probably be easier to do than this wooden bucket.

Yes, the demands and expectations on today's modern women is lot.... kill vampires, clean the house, raise the kids, plow the lower 40 AND STILL look fresh and act like a lady to the public( and be a complete slut in the bedroom), How do they do they it?

[4313B]

They're deft I tell ya!

Giskard:

Just some "general" questions and then I'm off this for awhile.

1. What's an AVR?
2.
A.What are the crossovers? a 6, 12, 18, or 24
B. How can one tell by looking?
3. In your reply you mentioned how if we did option 1 or 2 the crossover is set at 130 ( which I understand), However, in discussing option 3 or 4 you alluded to possiblity setting the crossover point at below 130 ( and not less than 80). Now my question is this...... In your listening to Mike's 800's ( and comparing with other speakers "LE14H-1's for VLF right now. LE14H-1's turned off half the time so I can compare the 8-inch with the old 112H/2108H") did you:

A. reach the conclusion that sonicly maybe a lower crossover point would be better and if so what was it?
B. In your discussion with the designer a year ago, did you talk about the crossover points ( 130 in particualar) and why they choose them.

thanks

Ahh, tools. I could almost spend almost as much money at the Rockler site as I could do on this JBL stuff.

AVR

[4313B]

6 dB / octave 130 Hz high pass to the PT800 when selected in the PS1400

12 db / octave 20 Hz high pass in the PS1400 (always on)

18 dB /octave 130 Hz or 300 Hz low pass in the PS1400 (must select one or the other)

[4313B]

"A. reach the conclusion that sonicly maybe a lower crossover point would be better and if so what was it?"

What crossover point I think is better is irrelevant. That's based on your sub choice, room response, loudspeaker placement, buttered or plain popcorn, etc.

"B. In your discussion with the designer, did you talk about the crossover points ( 130 in particualar) and why they choose them."

No. That wasn't an issue for me.
Someone else asked me that in a PM... Someone you know I think...

I think there might be a bit of confusion here. The PT800's do not require the PS1400's to operate properly at all. They will operate properly with any sub of your choice providing you have an AVR or an active crossover network such as a DX-1, etc. No surprise here; standard bi-amp fare. If you already have Citation 5.4's, Citation 7.4's, B380's, B460's, 4645C's, SUB1500's, etc then use 'em.
