Match for Infinity Kappa front speakers

[mmsdrummer]

I've got some Kappa 572.5 's for my front doors and they sound great with my Pioneer 750mp.

I'm wondering what anyone recommends for rear speakers. I wasn't planning on adding a sub, so I'd like to know a good speaker with great bass which will go with the Kappas. Should I go with round speakers? 6x9's? or something else.

I'm not running an amp but plan to later.

Thanks for any replies

You might be interested in either a set of components or 3-way Infinity's. Some others will have some more details I know.

Usually the key for any system... don't plan on bringing out the bass with loudspeakers, could blow the suckers out.

I'm not into a ton of bass, just some fill that the fronts don't provide.

I dont want to spend extra for componets (and i'm pretty happy with what i have)

Maybe 3-ways would be good...

anyone else have an idea?

The Boston Acoustics NX87 model have a good amount of bass. I have the infinity's in front with the bostons in back. They are about 100 on ebay.
