unobtrusive speaker system?

I have the Gallo A'Diva Ti's and they sound fabulous. They take a little time to work in but once they are worked in they sound fabulous....

I went with the D4 ERA's from Signal Path. Great sound and unbelievable bass from a small speaker. They also come in a smaller and larger version depending on your needs. Check them out at the link below. Good Luck.

Try the Magna Planer Home theater set up,great sound
with planer speakers front and rear plus center. Add Hsu sub for bottom end

orb audio is very similar to the gallo. Might be worth a listen.

Gallo has some small WAF friendly speakers.

As Tarasound suggests. May be some B&W or Parasound in wall designs. I have B&W in wall speakers all over the house.

how about the new ZU Cadenzas?
