Hi Folks,
Looking for suggestions on how to best utilize these drivers salvaged from an old tandberg telepresence device.
Looking for suggestions on how to best utilize these drivers salvaged from an old tandberg telepresence device.
I see these telepresence systems claiming full range 20 - 20,000Hz sound.
A bit optimisitic perhaps, but it suggest your drivers may have potential in the right cabinet.
Any idea of the type (sealed/reflex) and size of enclosure in which the speakers were originally situated?

Cute little Seas drivers. Maybe email them or do a quick google search and see if anything comes up.
Enclosure details for the W12CY003 woofer:
Volume: 3 litres
Tuning frequency: 60Hz
Port internal diameter: 20mm
Port length: 68mm
Low frequency cut-off: (-3dB): 67Hz

What? You're not recommending a dual woofer tapped horn and using the other 4 units for MTM tops?
I'd go 2.5-way, MTMWW.
I would, however, measure things before going further:
- Measure T/S
- Design cabinet for LF response
- Install drivers
- Measure frequency responses
- Design and build crossover
- Measure again, tweak crossover
- Enjoy.

Those are some nice driver you have on your hands there, especially the woofers.
They look like they are excel line magnesium cones with black phase plugs and cones. Nothing wrong with the tweeters mind you. In fact a lot of SEAS prestige line tweeters perform better than some of the excel ones.
I echo what Chris has said though. Basically a ZA5.5tt or a ZA5.5t.
Zaph|Audio - ZA5 Speaker Designs with ZA14W08 woofer and Vifa DQ25SC16-04 tweeter
That would be a good place to start for inspiration about what you could do with your drivers.
I guess what you build depends entirely on how many of them you want to use in a single speaker.
The magnet size on the W12s bodes well for a useful Qts. What kind of cabinet were these originally in inside the TV?

Thanks for interesting link, especially since ZD5 has been my speaker of choice in the last decade🙂 I’m not sure though if I can simply drop my drivers into MMTMM design for example, but it would be nice if they’d fit🙂
My woofers were inside a large cabinet with 65” screen, difficult to tell how much of it was used for sound though.

Difficult to say, I don’t remember any holes so probably sealed.
Zaph has his own drivers now? Seas manufactured?
I am revisiting this idea and looking into building something like this:
Eekels' Mini
With somewhat simpler crossover for a start.

I just discovered this wonderful speaker design software: Software , looks like it’s a blast! It can even trace SPL from graphic image, so my problem with missing .zma and .frd files is solved instantly! SEAS confirmed that my midbass is actually excel W12CY001, and I found tweeter datasheet as well at lautsprecher.de so I am good to go🙂
