In Reply to: Replacing the (shorter) T-IV midrange with the Neo 8s makes sense ... posted by andyr on September 25, 2010 at 00:56:23:
The T IVa midrange extends deeper and allows a lower crossover, but it is nearly identical, just slightly lighter wires than the T-IV it has better detail and transient attack, but still much slower than the tweeter, and the discontinuity is still obvious, as you probably noticed.
The Tympani, when braced and powered sufficiently (something that could just barely be done when the model was current). Do go down to 25 hz flat, and provide plenty of output below that - or actually have giant room gain at the bottom octave.
Had Magnepan used the same number of magnets on the Push pull bass then at least dynamic response could have been better, but they didn't so there is no real advantage it turns out, but for the lower cost and easier setup. Another minus is that it is easy to bottom out the woofers - where the tympani at least continue to give a half waveform on the lowest octave at high volume - much better than nothing on the MG20.x.
Its not really that bad to build Tympani these days, it should be possible to do it for less than $20k. The biggest cost increase in the Tympani construct relative to the MG20 comes from the dealer cost to set up at the customer's room. Second is the smaller production runs due to sales limitations from the limited WAF (think size) and greater cost.
