Hi
I use the dmt 10s, with my 300B's. They are great, I have not heard the 15's but I imagine they are sweet given their paper drivers. I upgraded the crossover parts in mine to alpha core inductors and hovland caps. I had to mount them externally but it made a huge difference. It was well worth the expense. I am bi wireing them with kimber 4tc sounds good but I really have not experimented to much with cables for the speakers.
The tannoy monitors don't get much ink here but I suspect it is because most people have not heard them.
Regards,
Keith

Keith,
I've got a set of DMT 10's, and will be be purchasing a 2a3 SET to drive them. How do the 300b's do with them, and I like to hear more about your tweaks.... Your right, not a lot of coverage on these.

Hi Scott,

I really like the 300B's with the 10's (welborne labs laurel II). You will have no problem driving them with a 2A3 either. I would like to have a 2A3 amp as well. I really like both tubes but don't really prefer one over the other.
As far as the tweeks, the only thing I did was upgrade the crossover parts, kept the same values. If you open up the back where the binding posts are and look inside you will see how cheap the stock crossover is. If you have the manual for the speakers all of the part values for the crossovers are listed in the back. Tannoys pro service is also great and responded to every question I asked them.

Enjoy
Keith

I'd appreciate comments or advice about using the Tannoy System 12 DMT monitors. According to the user's/service manual, these speakers are 90 dB anechoic, 93 dB half-space. I'm using mine with a Meitner PA-6i preamp and a Quad 606 (130 wpc) power amp. Tannoy, however, recommends for best reproduction of dynamics, a minimum of 150 wpc. In any case, I do from time to time like listening to music at (what I imagine to be close to) concert-level volumes and I find that, much as I like them, the System 12s don't have quite the output that I'd like. Yet I now learn that people are happily using System 10s with low-powered valve amplifiers. Am I just a headbanger at heart? My thought is to save up for the System 15 DMT IIs, but that won't happen very soon. Thanks. Joel.

 

the dmt 12 II should be more efficient than 93 db.., posted on April 21, 2000 at 11:46:57

my 10's are 95db. If you don't have the 12 II this could be the reason. The older 12 was less efficient than the mk II. Even if you are a headbanger, you should be alble to get all the dynamics you need with the II's.

I have found that using high power amps on real efficient speakers is very painful. When I first got my 10's I had a 300W/channel SS amp and thought that I could live with it for a while till I could get the SET I wanted. Well, I was very wrong. They sounded horrible, they literaly hurt my ears. Those high power ss amps don't even start to work unless you are pulling at least 20 + watts from them.
You my want to demmo a tube amp. you may be surprized.
Good luck
Keith

Keith,

You're right; I've got the DMT 12 (early 1990s, I gather), not the DMT 12 II. But there's no doubt about the efficiency, the 90/93 dB is straight from the manual.

Do you happen to know what changes were made in the DMT 12 II which increased the efficiency? Is this something a crossover rebuild, praise of which I have read in this forum, could accomplish? Or are we talking about the manufacturer using different magnets or something fundamental like that? Also, is it true that the DMT 12 IIs weigh in at something like 70 lbs. each? The DMT 12s are only 57 lbs. -- and that could be due to a lot of reasons. I'd appreciate it if you (or anyone!) could shed any light on this. Thanks, Joel.

I can appreciate what you say about transistor amps and high effiency speakers. Many friends gently chide me at my hesitation in moving to valve amplifiction. But then they all have full-time jobs...

Keith,

Can you point me to any published information about how and what to upgrade in the DMT crossovers? (I couldn't do it myself, but I do have access to a very experienced and reasonably priced techncian.)

Thanks very much.

Joel.

great discussion on these speakers. What validity is there to Dr.Gizmo's assertions that Tannoy professional speakers aren't available in the US? I am curious, for I purchased my 15DMTs from overseas-airfreighted to me here in the Northeast....cheers, Michael

Im not sure exactly caused the increase between the 12 and 12II.. I have never seen the standard 12, However on the Tannoy web site they have a different part number for the complete coaxial driver for the 12II. The 12II does weigh about 70Lbs. My 10's weigh 50 and the 15's weigh 100lbs ea. Rebuilding the crossover won't increase the efficiency (unless you change the values) which I would not recommend. Tannoy has great service, check out there pro web site, they are real helpful.

Does anyone know of a North American source for the Tannoy DMT 12 II, possibly NOS? I've seen 10s and 15s on eBay, but not 12s.

Thanks,

Joel.

They don't make the 12 or the 10 anymore, only the 15. You may be able to fimd them used.
As fir the crossovers, I would replace everything, and mount them externally- you probably wont have room in the box for the upgrade parts anyway. I don't know of any published literature on upgrading that crossovers. They are real simple and the values should be in the owners manual.

Tannoy/TGI in Kitchner, Ontario, Canada is the North American distributor. They sent me a Professional Products Canadian price list a while back, so I assume they also supply the U.S. market. Contact information should be on www.tannoy.com. . .They even make an active version of the 12" studio monitor now and it is distributed only in North America.

Hope this helps.

Joel.
