To my ears, this is the best speaker I've ever made.
I have no trouble driving the DTQWTs from my 8 wpc 300B SET amp.
In many ways life gets easier when we make big speakers. We may have
more and bigger drivers and distortion may all of a sudden be reduced significantly because none of the drivers have to move much to produce high sound levels.
Compared to all other speakers I've made, the area where this speaker differs the most is in its ability to reveal musical transients.
The speed and attack it can produce is something none of all the other speakers on this website can manage. It's fast, very fast. A drum solo will kick butt, even from a 10 wpc amplifier.
As can been seen from the graph above, we have a
minimum 6 ohms impedance (red line inserted) and as stated in the beginning of this article, 8 watts from a SET amp can drive this speaker to significant levels before running into trouble. In fact much louder compared to average home-audio listening level, which is around 85 dB. This doesn't mean that 20 wpc can't do better if you want to play even louder. The DTQWT can play enormously loud before significant distortion occurs.
Remember, with 1-2 watt input we may have ~95 dB at 1 metre distance - and this is loud, really loud.
