Thiel Owners

Tom T & Tom D

Thank you for your guidance , now I don't have to agonize or worry about making a bad decision with inductor guage .

I had looked into the foil inductors after beetlemania's positive experience, but they are to large in diameter and they don't come in the smaller guages that are used on the Thiel crossovers .  

As for resistors , I already have about $100 worth of Mills mainly because of having to parallel resistors to achieve value and wattage .

Moving the crossovers out of the speaker cabinet has interested me ever since I saw an Italian speaker for sale at Echo HiFi in Portland , this is was and is the only speaker that I've seen with external crossovers .  I'm still wondering why this isn't more common on higher end speakers , but me doing it is just beyond my ambition and capability .

The simple and rewarding act of changing mounting screws has remotived me to start replacing componets on the crossover boards .  Rob

tomthiel,

At some time there will be a stand-alone short run of perhaps 50 pair of this re-imagined monitor. No promises or projections as to when.

I'll be waiting, with interest!

Happy Friday! All

Thank You for the history lesson on Model CS 2.4 and follow up to my query.

I am certain that 50 pair of Renaissance Monitors is highly achievable. Good to read that you are well and making progress. Have fun!

Happy Listening!

I understand Tom Thiel has been working with surface treatment of a speaker baffle to enhance laminar flow while also reducing interfering energy. This energy migrates back and forth on a vibrating surface and causes a pile up of noise that does return back down the speaker cone colliding with the next wave launch. Everything vibrates and everything that does generates shear waves of many types. Shear waves travel in 2 or more directions and their collision create an infinite amount of more collisions.  These shear waves only travel in solids and all materials have a different shear velocity. The music we hear is the result of air affected by the shear generated in these solids. The air contacts the solid surface, so the air vibrates, and we hear those vibrations as sounds. Shear wave velocity passing thru any carpet will be changed by the material and the density. Hardwood and glass both have their own unique velocity. Look at your room materials and shape that is why they sound different. The compressive wave upon impact creates shear wave and those in turn travel and impact other solids and make more shear and compressive waves. And the beat goes on...This is a regenerative process. Because these vibrations generate sound you don't want to kill them all. It's tough to be selective without causing more harm than good. 

The early work of Jon Dahlquist and his use of spray materials. Spray flocking on the baffle and spray Nextel on the cabinet was the first surface treatment that ever made a profound impact on the sound of a speaker cabinet with no woof tones just more refinement and clarity. I know this impact as I heard the same cabinet untreated and then months later returned to me as treated.

Bud Purvine's patent on the Enabl process probably achieves much the same but applied directly to the driver surfaces His method launches away polarities of shear and Raleigh waves so they reduce collisions with the next wave launch..Bud now considers these waves as Rayleigh waves.

Over the last year I implemented laminar flow devices I have built and placed in strategic front locations of my 27/21/9 ft room. I also have for years used now 3 Natural wool panels on the front wall 1 each at the side reflection points. The laminar devices are inexpensive to make and are the biggest acoustic improvement I have made over the last 49 years. They are a wow factor.  Small in stature they seem to comb bass frequencies making my dueling 12s enhance the mid frequencies. With placement the vocal clarity now coming out of the rear mounted ports is nearly as clear as what comes out of the front mounted drivers. They clarify the instrument location all along the watchtower. The sound stage is panoramic even more so when the active device is engaged. Pretty much the room boundaries and its contents are gone. Looking forward to seeing and hearing the Pauley and Thiel front baffle treatment..Tom D
