6 ohm woofers in series

[jmechie1]

I'm considering using Mission cf200/78 drivers (2 per enclosure) to make a set of floorstanders. I'm having trouble finding any TS parameters for them.

I know that they're 6 ohm impedance, so I wanted to know what effect there would be by connecting them in series? ie, sound, performance, power handling etc..

Cheers, James

It is easy to measure the T/S parameter. You need a PC computer, a sound card with a line input, a resistor (33 or 500ohms) and a mini jack to jack
See my tutorial.
Woofers in series, almost same in parallel but double impedance, same SPL.

J,

If DCR = 6 Ohm then Nom Imp. = 8 Ohm.

Parallel connection is preferred so long as the amp you use can handle a nominal 4 ohm load. You want to avoid the addition of impedance peaks that occur at driver (system) resonance.

Enclosure design should be based on measured driver TSP's not the published ones. This is the DIY advantage, but measure twice, then cut once.
