Question about SPL

Audist · 15th October 2008, 08:40 PM

Hi,

I have woofer of 4 ohm and 89dB.
If I use with 2 same woofers and connect them in series to the amplifier, I got same 89dB but 8 ohm? Correct?

Thanks

generally speaking ...correct
when you double the amount of speakers, you gain 3dB
however you doubled the imedance too, so you loose 3dB
in detail it depends if your amplifier is voltage or current one....
