It is great to have a list of manufacturers for building a speaker. I want to try a low powered tube amp and suitable very efficient small speakers for an extra room. I can't tell the efficiency of these speaker kits. Does anyone have a kit or specs for such a speaker? I want something in a minimonitor or bookshelf type and something mated to a 5 or 10 Watt tube amp that I will make. Thanks.
