Speakers for a 15w 6v6 integrated amp?

I have a 1961 Bell integrated tube amp using 4 6v6 tubes.

I have used this amp with great results on the following speakers- a stacked pair of Quad 57's,Tannoy Ardens,Ref 3A grand Veena, Mission 770, Meadowlark Heron i,it has always been a surprise to find a speaker that didn't work well with it.

I think there will be a lot of great speakers out there besides the usual suspects,that would prove a good match for your amp,just use common sense and watch the volume.

15 watts will rock a Klipsch Heresy or Cornwall. For a more detailed sound the Triangles are also good but you'll need a sub.

I immediately thought of Ref 3A, if there is a dealer in your area. Or in Europe you may find used, some of the earlier Ref3A speakers that were sold under the Innovac name, like the Royal Master monitors or the Suprema 2 piece speaker w passive sub.

I second the Quartet. Nice smaller foot print-Efficient and 3way.
Upgrade the mid/tweet diaphrams with Crites and you will really hace something for under $400 if you shop right.
Oiled oak finish is the way to go.
I prefer this speaker to the Forte on up. The 3-way avoids the KG 2 way issue with recessed mids-but give you a tighter, yet large bass response that seems more balanced IMHO over the larger Forte and up.
If you want sheer concert levels- you will need the bigger speakers- but for most poeple the Quartet is just fine- and rocks with the best of them.
