Speaker Break-in Revisited - Page 2  

post #31 of 38
Thread Starter 
Let me throw another log on the fire ...

Thiel speakers are known to be some of the most "scientifically" designed speakers on the market. Based upon very sound principles.

A couple excerpts from their web page:


Q. What components of THIEL speakers are designed and built at the THIEL factory?

A. We design and manufacture THIEL speakers at our 40,000 sq. ft. factory in Lexington, Kentucky, USA.

The design phase includes developing drivers, crossovers, and enclosures for all THIEL loudspeakers. We use several advanced testing, measuring, and evaluation techniques in the design process. Computer simulations, anechoic testing, and the human ear are all used to ensure thoroughly and completely engineered products.

The manufacturing operations include hand-selecting veneers, precision machining of cabinet parts, hand-assembly of cabinets and crossover networks, and testing of each and every speaker prior to shipment.

As the only U.S. high end company that designs and builds its own drivers, THIEL can provide driver performance that is perfectly matched to each model's requirements and develop speakers that take full advantage of our design innovations.


More design philosophies can be found at:



In Thiel's speaker manuals, Jim Thiel includes the following paragraph (this is from the CS6 manual)


The CS6s, like most speakers, require a period of playing before they perform optimally. The time required depends upon how loudly the speakers are played; more time is required if played softly, less if played loudly. At least 50 hours at moderately loud levels are required before the speaker is performing near optimum. You should notice even more improvement after 100 hours of playing."

Tom---Yeah, but the thing with Thiel is you don't know whether they really believe that or they're just pandering to their high-end customers who expect to hear that kind of thing. That statement could be coming from the marketing people and not the designers.

Besides, they lied already when they claimed they were the only American "high-end" speaker company to make their own drivers.

I am curious on this one... So, who else makes their own drivers, and who definitely does not?

Sushi----Magnepan, Martin-Logan, Soundlab, B&G to name a few. Also JBL makes their own drivers, they have a high-end line for Europe and Japan which has recently been introduced in the United States. And Revel, a Harmon company, uses drivers made by themselves and by other Harmon companies such as JBL.

And the new Iconic company makes their own drivers too.

I like the way Thiel brags about their new woofer with it's short voice-coil in a long gap, like it was something new and different. The kind of thing James Lansing and John Hilliard were doing in the 1940s, check out an Altec 515 or JBL D-130. So Theil goes to 1940 motion picture theater speaker school and discovers that those old guys knew what they were doing. But then why wouldn't they; they had the resources of Bell Labs, RCA and MGM behind them. :-)

I don't believe that is the correct definition. Elasticity was defined to me by my physics teacher as the amount of "stretch" something has. The more something will stretch the more elastic it is.

The ability of something to return back to it's original shape was her definition of resilience. And, yes, steel is more resilient than rubber.

I know it's a minor thing, but I couldn't believe someone was actually talking about this probably the same day I was explaining it to a coworker.


I don't believe in electrical components "breaking in" like some would explain. They, too, can change over time but not like speakers. I do believe materials in speakers change enough to hear a difference. It is easily believable that materials used in speakers will change after hours of vibration.

I also think our ears change so we get more accustomed to the sound we are hearing. This changes our perspective of what we are hearing. I think this effect is what makes it so difficult pinpointing the changes that are real. As the picture Sushi posted (if they are the same darkness 'cause I can't tell), tricking the Human brain to believe something incorrect as the truth is not difficult at all.

How dare you say that about me and my kindred spirits. That sort of talk makes me angry - I am going to continue to complain about your comments until you apologize (or at least buy me a car to keep me quiet)


How little you know - I only appear self centered because most of what I do pleases me.

>> self-congratulatory,<<

There you go again - teying to make me feel guilty simply because I am better than you.


That is absolutely off base - I remember at least 5% of what happened in the seventies.

>>and delusional generation in American history;<<

You would think that - you can't handle the fact that I am equally talented in electronics, economics and yoga. I spend many hours at the keyboard refining my background...

>> it's no surprise to me that the demented aspects of this hobby took off big time when the Boomers became involved. [/b][/quote] <<

I have become comfortable in knowing that hard nosed conservatives (or liberals - depending on whom I am defending my generation against) such as yourself are invariably wrong in your evaluation of me. Thank goodness my ego is strong enough to fend off any feelings of guilt... :D
