LPT 100/19/130

Why?

Hi, Thomas
I have pair such loudspeakers and I wish to calculate a labyrinth.

Measure it by yourself or find s.o. who does it for you. It´s not so complicated.

Thanks for advice.
I have made some measurements, and wish to check up result.

Hi,

LPT 100/19/130 ?
"T" means low frequency driver, "100" is the diameter of the basket.
My old catalogue shows parameter for LPT 170/19/130 only.

Hi

Thanks for courtesy to my problem.
I have seen the information at a forum. How much I remember, it You have placed file ITT_Spec.gif and some specifications. I hoped, that in Your catalogue there will be also a specification on LPT 100/19/130. Unfortunately, it not so.
Whether is present in Your catalogue the specification on any loudspeaker of series LPT 100?
I think, that mechanical parameters will not differ very much.

Hello, all
I managed to find the necessary information. Here parameters of loudspeaker LPT100 /19/100 SG. I thank all for discussion.
Best Regards
