produces a time aligned wave-front with a 360 degree radiation pattern. This very much resembles the wave pattern produced when a stone is dropped into a pond. These waves are perfectly coherent and aligned with all other waves leaving the cones surface.

suffer from beaming or high frequency drop off when listened to off-axis because the sound is being delivered equally in all directions. It is this nature that allows one to move from side to side with very little change in sound quality and therefore more closely resembles a natural point source radiator which all instruments tend to be.

their voice coil and magnet motor design. The spider assembly tended to be too soft and allowed the voice coil to droop or hang out of the magnetic gap resulting in poor efficiency and the need for tremendous amplifier power. This often resulted in driver damage or voice coil burn out. Our New design addresses these issues and more resulting in a true Under-hung voice coil design and a net gain in efficiency. While our new design requires less power and it is possible to drive the speakers to very comfortable levels with as little as 10 watts, we find that it is extremely beneficial to use a minimum of 100 watts per channel up to 400 watts per side. This extra dynamic headroom allows the speakers to open up and breathe resulting in a much more defined stage presence and overall clarity.

other speakers for that matter. They can be overdriven, which can result in severe distortion and or cone damage. The present design allows for an Xmax (cone move- ment) of around 1/2 inch.

TLS-1 and 2 series deliver superb bass, these speakers were designed to deliver the ultimate in musical experience. There is a big difference in Home Theater and typical musical enjoyment. The Walsh driver will leave you breathless with lifelike music reproduction and can even knock you out of your seat with gut wrenching bass, but I do not recommend them for home theater sound effects. For this I suggest I-Beams and extreme sub woofers.

all, it is a lot of money to invest. Can you justify my expenditure? Why refurbish my old speakers vs new?

are ranked as mid-priced amongst the high end products presently available. Further, the original speakers had a closing price of $4,500.00 in 1984 when production ceased. Adjusting for inflation, the TLS-1 should have a price tag of no less than $10,000.00 in today’s market. At HHR Exotic Speakers, our speakers contain no less that 36 improvements over the original products with more in the works.

compare to other high end offerings?

speakers ever produced. In fact they have been known to compete with speakers in the $50,000.00 range.

Our current production speakers and rebuilds are far better than the originals and still rank among the finest speakers in the world. They are works of art both in musical reproduction and are visually stunning.

 

decayed. Why can’t I simply replace these and make the speakers work again?

thickness and resilience along with the spider to give the speaker the correct compliance. In addition, the surround is largely responsible for absorbing and terminating the sound wave as it traverses the cone length one time only. The wave must be completely terminated or the reflected wave will return up the length of the cone and interfere with the oncoming wave fronts producing distortion and coloration. These surrounds are made to my specifications and are not available off the shelf.

should I do? Only one speaker has an open VC, can I replace only one?

will blow and still look like it is intact. Or, it in fact can be blown open. If the VC is in fact open or shorted, it can be very carefully removed and replaced with a new VC. If these are Old model F’s then Both speakers must be upgraded to the new VC, as they are different in design and weight. Replacing only one would completely mismatch the speakers and created differences in the response, efficiency, and overall performance.

pulling the VC out of the magnetic gap. It still plays, but not very loudly. What can I do?

relatively heavy and thereby due to gravity and age tends to pull the spider downward causing sag. This also affects the surround as well. While there is no easy way to prevent this problem, I have reduced the tendency for this to occur by utilizing a heavier spider with greater stiffness. The spider looks the same, but is in fact stiffer by design and is made to my specifications. It is not an off the shelf item.

surrounds?

therefore be replaced as one item.

to have just basic repairs done? I had a friend that sent his to another recone expert and it was much cheaper. How do I know that you are not just ripping me off?

appearance and operation. The average reconer will simply not fully understand the operation of this driver nor the consequence of replacing worn parts with just any old part. While they may do a very nice job and indeed the speakers may play, they will not be optimum and perhaps even sound bad. This results in giving the “F” or the “A” a bad name, and perhaps worse an unhappy customer.

particles fallen from under the driver when I remove the driver from the base. What is this substance?

of the internal damping foam to rot from years of exposure to air and elements. I can assure you that if your spider is sagging, if the surround is decayed or rotted, then the internal damping foam and internal damping putties have decayed as well and all will need to be replaced.

Why should I pay you far more than this per driver to just have these repaired. I don’t see the logic in that.

this fact has been printed and confirmed by many, many sources since the release of these speakers in 1972. Consider also, that $500 in the 70’s is an equivalent of over $3000 today and that, in fact the closing price for these speakers in 1984 was over $4,000 dollars. In addition, the current price for the TLS-1 is at an introductory price of $5,000. It therefore seems reasonable to assume That a small investment today can result in speakers worth far more than you paid for them, and you will have one of the finest loudspeakers ever built.

only use piston drivers, not to mention they cost far less. What makes these so special?

panels and even full range ribbon drivers use crossovers. Crossovers produce time and phase distortions and introduce all manner of electrical signal distortions All Box speakers are limited to a maximum of 180 degrees dispersion and more likely a much smaller amount. They tend to sound hollow, lifeless and have critical room placements or a sweet spot. The stereo image tends to wander and the open airiness or spatial depth is lost. The Ohm F and A, and now the TLS-1 and TLS-2 do not suffer from this problem. They have no crossovers whatsoever. They are a single driver covering the entire audio range from 20 Hz to 20 KHz. The Walsh driver emits sound in a full 360 degree pattern and more importantly, the sound is perfectly coherent, analogous to a laser beam. The sound waves are radiated from the slant surface of the cone in a perfect cylindrical wave front. This driver acts more like the ideal “pulsating cylinder” than any other speaker ever devised. It is in fact the only driver in existence that can pass a square wave with almost 98% of the original wave retention, possessing extremely fast transient times and very fast decay rates.
