Thiel Owners


Guys-

I just scored a sweet pair of CS 2.4SE loudspeakers. Anyone else currently or previously owned this model?
Owners of the CS 2.4 or CS 2.7 are free to chime in as well. Thiel are excellent w/ both tubed or solid-state gear!

Keep me posted & Happy Listening!

anzen - it’s a complex, multi-dimensional puzzle. In terms of pure signal propagation, PCBs outdo most PtoP layouts, especially if one-sided. PCBs shorter leads create smaller antenna effects. A new insight (to me) is how signal chaos is created when P to P has inputs and outputs entering the same solder-lug from the same direction. Two-sided layouts allow that distortion mechanism to be eliminated - with care and extra hassle. A requirement in this Renaissance project is the variety of quality levels supported in the same package. I want my layouts to accommodate various sizes of components. And on and on.

Placing the boards vertically facilitates thermal management via convection air over all component surfaces. Heat dissipation is a big deal for circuit stability under load. Edge mounting is more difficult and more optimal - but worth the effort since I’m aiming for a higher performance plateau(s) than original Thiel products. I’m pleasantly surprised how much room for improvement exists in the same platform with the same drivers, circuitry and cabinet.

Best material for XO panel is Panzerholz, German compressed and heat treated wood product that is extremely strong and internally very well damped - and very expensive. Next best is 1/4" masonite which comes pretty close at 5% cost. Outboarding significantly reduces need for vibration control. For inboard panels I’m suspending the panel in rubber grommets to decouple from cabinet panel resonance modes. Again, I’m pleasantly surprised how these various aspects accumulate into cleaner performance.

To answer more directly: I will be using wood-based point-to-point panels exclusively for their strength, superior electro-magnetic performance and layout flexibility.

Thank You for your Dedication and Passion for Thiel Renaissance project. Upon release, the Audiophile community and press will take notice.

 

Happy Listening!

Tom  Thiel, 

Are you stating you would mount the crossover board up right on edge? If that is correct this would expose the circuit board direct in line to the most significant mechanical impact from any open back driver in the cabinet. Visual would be a basketball hitting the back board. Damping would reduce but will also increase  the resonace retention time of any aquired energy which can become part of the orginal intended signal. My methods are much different  1 of which allows for external adjustemt of the resonance point of the internally loaded circuit board. Resonace will be drained thru the bottom mounting method and coupled internally to cabinet bottom and externally  to the mass of the floor. This feature benefit can also be done on a preferred external mounting method. I think we have discussed  these methods in the past. I know your project is to be simple and of a high value. You may want to offer up these significant options for users who want to max out resonance control. There is also an option to externally resonance tune the woofer to the backside of the cabinet. This entails a brass connecting rod and a special tuning bolt turned by hand .Like you would tune a stand up bass. Significant audible upgrade. I know your trying to increase open surface area to benefit heat dissapation..Resonance tuning also reduces thermal runaway as the heat has a method to transfer as does resonance.. TomD
