FYI: Thiel stained bare wood; if stained, the clearcoats would be on top of stain. If natural, the clear sealer and topcoats would be on bare wood. Refinishing is serious business. Are you experienced? You might consider some form of over-coat, li...

Jhouse - your speakers certainly do look altered, that's not a Thiel factory finish. The veneer looks to be Mahogany, which has a natural color in the salmon spectrum, which is generally stained some shade of red-brown. It looks like yours have be...

George,It's been my pleasure. For the record, I concur that the 2.7 is the mature work of masters of the craft, what tool-heads call ' a clean machine '. Any performance gains will come with significant expenditure. I'm happy to have you enjoying ...

Prof - Paul Hales is very talented and precisely educated. He got his degree in mechanical and electrical engineering for the purpose of designing loudspeakers. Rossw - To me, the 3 / 3.5 seems the quintessential Jim Thiel design, before he had to...

Guys - thanks for the grace for my rant. The marble baffle was a work of art as it stood. The concrete of the 6 and 7 has its own story. My last project in the mid 90s was developing a lower cost baffle for the 6 and 7, which was a Hydrostone prod...

Unsound - agreed on 40Hz, and even 20Hz at moderate levels in a moderate room with moderate music. I like the 20Hz 'sound' better than 40Hz, possibly because of the relative lack of low end phase shift, to which I am sensitive. The bass response e...

A Renaissance 3.5 would require all new drivers. The extant woofers are bulletproof and decent, but lack the sophistication of later designs. They are a 1985 solution. The replacement midrange needs to be a full range driver, which is findable, we...

unsound - points well taken. Thanks for your linked reminders. And a comment here. My thought was more from the perspective of the extreme difficulty of producing so much bass with the dynamic range and extension possible with today's digital tech...

catalysis - I second your motion re the subs.

Rob - a word for the record about insulation. There's quite a bit to it.Common wisdom is that wood  is 'better' than glas, etc. , which I believe oversimplifies the situation considerably. The various materials act differently, so even at equal co...

Unsound - I like seeing you think outside the lines. Indeed that coax is a work of art that should find additional uses. To add some perspective, let me summarize Jim’s design process.•The drivers are developed against their optimum criteria.•Each...

The bottom line is similar - major surgery required.

Hello rules - I suggest that the 3.7 chamber is probably larger than the 2.7 because the 3.7 XO frequency is lower than the 2.7 judging by the larger capacitor bank at the infeed of the 2.7. Redesigning a speaker is a massive undertaking. Budget a...

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 cab...

slhibj -  Limited knowledge and experience here. I hope that directly experienced users will comment. Although the FR and other performance and technologies of the SS 10F are appropriate, I worry about the 30 Watt power rating compared with 50 or ...
