It's hard to say if those T/S specs are indicative of a substandard recone or not. Electro-mechanical specs vary quite a bit with power used, so what you measure with a 0.1v signal is not the same as what you measure with a 0.5v signal.
But what will really tell you if the speaker is acceptable is acoustic measurements. The real tell is how the amplitude response looks above 500Hz.
