Thiel Owners

Go guy! Just for grins, my 3.5 dream that never was is to mate the hotrodded unequalized 3.5 to a subwoofer crossed at polarity correct 2nd order low pass to the natural roll-out of the sealed 3.5 bass, which is perfectly aligned in its sealed cabinet. If you have the skills and inclination to mess around with that project, I'm available to work with you. 

At the risk of appearing redundant; I still wonder if the 3.5's baffle could be modified to accept the co-axial midrange/tweeter from the 3.7's. Then we would have a genuine Thiel replacement and the advantages of a lobing fix. Sort of a time reversal of what Jim did when he took drivers from previous higher end models to use on newer lower cost models.  

Unsound, I seriously explored that option with Rob and measured the cut out and increase in volume that would be needed. Concluded that it is doable and the coax driver are available and if you need to replace both the mid-range and tweeter, financially equivalent. I postponed that option and experimented first with a good wavecor mid-range driver and using active dsp tried out various eq and xo designs. As I can compare it to the original 3.5 and 3.7, I am pretty satisfied with my results. 

Tom, I have a pair of sealed subs and if this summer will be slow, I may explore your suggestion more.

Talked several times to Rob about the 10F as the mid-range replacement but never got excited about this option in spite of Rob's claim that it was the best replacement. The difference is size should affect the time coherence even if it may not be audible.

@thielrules, Thank you! What kind of expense would one meet to retrofit the co-axial's to the 3.5's?
