I got a 45 amp in the 1.5w range, and for me Coaxial Speakers* in a open
baffles seem to work great. For DIY, 3 way green cone speakers seem to work well too. Dig around here http://www.lampizator.eu/ Horns while they have good a sound don't match well for small domestic systems.
* any brand you like over 96 dbm .
Lundahl Set 45.

Seems to me that a two or three way, with wide dispersion horns (for tweet and mid, if used) and matched directivity should sound fine. The controlled directivity is actually a strong advantage. The efficient bass driver and its alignment could be designed to work well for use in a small room, with wall loading and the high output impedance of the SET amp... Such systems have been successfully realised.
Cheers.

Leaving 12dB for the dynamics of a song (the absolute minimum for me, I usually work with 20dB) and using a 96dB/1W speakers the maximum listening volume with a 1.5w amp would be around 85.5dBSPL. Any louder and you are just adjusting distortion levels.
Might be ok to play modern, over-compressed pop at low volumes though.
Seems fine for the many people who consider average levels of 85 dB rather loud. A lot of folks around here would not consider 85 dB loud though. It will work for many, but not those that like what most would consider very loud.
Personally, I don't listen as loudly as most, but have opted for ~ 100 dB@1w spks and ~ 4 W SET amp to minimise the risk of running out of headroom for most music.
Cheers.
