Default Speaker recommendations

Hey first post here . . . I think it's in the right place.

Anyway, I was browsing the web and was quite taken by this diy portable speaker system someone made: http://metku.net/index.html?path=mod...ter/index_eng6 (It's easier I think if you flick over the link than I blabber on about it)

I would like to have a crack at making something similar myself and plan on using the same amplifier - Amp6-Basic from http://www.41hz.com/

However, the ghettoblaster maker does not elaborate on his speaker setup and me being new to this stuff don't really know what I should be looking for with regards to speakers. I have searched the internet on how to match speakers to an amplifier and this page: http://www.satcure-focus.com/icetech/page2.htm told me "it's a good idea to buy a speaker of the same or slightly higher RMS rating than the amplifier needs" using a 100W amplifier with 4x 30W speakers (=120W) as an example.

Taking this to heart I came up with these full-range speakers: http://www.partsexpress.com/pe/showd...290547#reviews As the speakers have a rating of 15W RMS and the Amp6-Basic outputs 2x25W I though that I should use two speakers per channel (30W per channel) which as the site above recommends would be slightly above the amplifier's RMS rating.

P.S. I just noticed the speakers are 8 ohms while the amplifer is 4 ohms (I think). Is that bad?

I would greatly appreciate it if you knowledgeable people could please help me out and tell me if my reasoning is alright or could be tweaked or if I'm heading down the wrong track. Thanks.

Hi,

2 8 ohm drivers with a 4 ohm amplifier will be fine.
They will not be particularly loud.

see : http://www.partsexpress.com/projects...roject=Podzuma

Thanks, sreten. Even though 8 ohm drivers would work, would it be better if I used 4 ohm drivers?

Hi,

Twin 8 ohm drivers = 4 ohms. Do not use twin 4 ohm drivers.

... or this one:

Three threads started in approximately one day, all with the same question, and all with well-intentioned and helpful replies. Might we hope for a fourth?
