I have Z-4 logitech at the moment and they sound great, but i am think of upgrading to the new logitech G51 surround sound.

one thing concerning me is the size of the sub-woofer's driver:

for Z-4: 8-inch pressure driver at 23 watts RMS
for G51: Down-firing 5.25-inch high-excursion driver at 56 watts RMS

obviously the Z-4 has a bigger driver but the G51 is more powerful.

my question is, i have the impression of the bigger the driver, the more base it can pump out. but the G51 is more powerful, so which set of speakers will give me more bass?

do you have any other suggestion? any known problem with the G51?

your reply is greatly appreciated.
cheers! :thumbs:

With bass, you have to shift a lot of air, so I think the bigger the better.

I would say no it doesn't matter.
What matters more is the enclosure that the sub is in.
If it has been designed properly then you can get great base from just about any size speaker.

I used to have a Kenwood sub that had a strange shape. Almost looked like a trumpet/vacuum cleaner/canon.
It had great base.
It developed a problem so I opened it up and was very suprised to see that it only had a 6" speaker in it.

generally bigger the sub the easier it is to play low bass.
some speakers system use the cabinet to embassies certain frequencies but that can have the problem of poor quality. however 90% of people wouldn't know what good audio was if it jumped up and bit them.

most computer speakers do not play any bass, they only play mid bass.
fit a good amp and 12" sub and you will notice a HUGE difference.
