Tube Friendly Speakers - Down to 30Hz - $3000?

The JM Reynaud line would be worth looking into.

They are all right around 90dB and have flat impedance curves that hover around 4 ohms.

I drive my Offrandes with 13 wpc to satisfactory levels.
Offrandes and above are also rated to 30hz, although when I had mine measured once they were -6dB down at 30hz and 0dB down at 35hz.

Used these would fit the bill or move up to Concordes

Thanks everyone for your thoughts. There are some excellent ideas here.

Tvad, I did some modelling and what you are looking for (89 dB efficient, -3 dB at 30 Hz without significant reinforcement from nearby walls, fairly small footprint) is definitely possible. An 89 dB efficient woofer in a 3 cubic foot enclosure will give you honest extension to 30 Hz.

Note that marketing department claims can and often do wax a bit optimistic, but the basic tradeoffs of box size vs efficiency vs bass extension that the engineers work with are pretty consistent, at least in this quadrant of the galaxy. An overly optimistic claim doesn't mean that the engineering is suspect; only that the marketing department's claims aren't reliable. I can think of a manufacturer who exaggerates bass exension claims by almost a whole octave, yet in my opinion builds some very competitive speakers despite their (imho) questionable marketing approach.

Tvad, I see you have ruled out the Druids. What didn't you like about them? I know, from previous posts, that you weren't impressed with them at trade shows, but if you can get a listen in a more acoustically friendly place, you may like (love) them. Possible? peace, warren :)

I don't want to rehash this. Suffice it to say, they are not under consideration. Let's leave it at that.
