Mark of Authenticity
Printing crisp foil text directly onto flexible insulation is incredibly difficult—it requires specialised machinery and gives rise to inconsistencies. So why go to those extra lengths? The difficulties in manufacturing also make the cables much harder to counterfeit which assures our clients that these are genuine Tellurium Q® high performing cables.

Black II Speaker Cable

Tellurium Q Black was our first cable and we knew we were on to something special when we took the prototypes to various dealers for their comments and input. One in particular would not believe that it could match the somewhat thicker more expensive cable in his demonstration system.

We sat down and listened to some of his familiar music tracks, then we swapped the cable for Tellurium Q Black. He sat forward, looked at us and quite seriously asked what else we had done to his system while we were changing the cables over. It was only when he swapped the cables himself a couple of times he believed the evidence of his ears.

So why Black II? Despite Black winning multiple awards, surprising owners with it’s performance and more people than ever choosing to use it in their systems?

We have been learning and developing, especially in the last few years and have come up with a way to make this little gem even better. The only thing to do was to give it to our customers. Switch Black for Black II and it is completely obvious which is which. Once you hear the difference, it is also completely obvious why we felt compelled to upgrade Black in the way that we have.

We think you will get more from your music and hope that you love Black II as much as we do.

Blue Family

Warm and forgiving for systems with a slight edge or for those who like a more smooth laid back presentation. Blue and Ultra Blue are especially good for AV and home cinema.

Black Family

Smooth, fine detailed and great resolution while actually reducing apparent harshness. Music is presented as a coherent, organic whole, with a jaw-dropping sense of realism and naturalness.

Silver Family

Totally uncoloured, acting as a wide open channel sounding unforced, vivid and dynamic with phenomenal resolution, transparency and natural tonal colours. All this while sounding extremely analog and coherent, from the exceptional top end extension to bottom with finely detailed, separated bass notes.

Reviews and User Comments

“Whatever you did to the Black II… is good! ? I heard better micro-dynamics, improved transparency, and didn’t noticed any changes in tonal balance.”

“considering what the Tellurium Black II speaker cable achieves in my system at its modest price, for me it represents incredibly good value for money. There is absolutely no snake oil here and it comes very recommended to try out.”

“During last days I had the possibility to properly evaluate the new Black II speaker cables. When for a very SPECIAL product it comes the time to be updated, I have doubts and tell myself… ” can perfection be bettered?” Well, this is one of the times that I can only say a fully convinced YES! Bettered clarity, focus, general credibility, and a better bass control. The Black II authentically remains a Tellurium Q Black with its unique features of a natural, spacious, fluid, rich, and expressive sound, but bettered. I don’t know how you did it, but you did it! I want to congratulate Mr. Geoff Merrigan and Tellurium Q for the great result.”

“The Tellurium Q Black II speaker cable is a great standard of what an available cable should bring to systems.”

“Two days ago I bought 2.5 meter long tellurium q black speaker cables. I am very happy: Transparency, detailed no harshness. I never heard music so well in 26 years .

Bravo !”

“With the Mk2s there was more air around performers and greater control at the lower end, the originals sounding homogenized in comparison. The bass lines were easier to follow and there was a smidge more clarity across the board..”

“Hi Geoff,

I would like to give you some feedback, but not sure where to start. I can only say I am very pleased with the cables, it has opened up my system to an extent I thought impossible and this is with the Black Cables, so not sure how it can be even better with your high end cables.

The best way to describe the change is really that my wife always say “Sounds the same”, when we try or listen to some very high end Hifi Equipment, but as soon as I had installed the cables, she said “sounds much better and much more open Music, almost like being in the concert Hall”. So this is properly the best way to describe the change.

I am Marine Engineer with Electrical engineering included, so have to admit that I was sceptical of how much a cable could improve the sound, although I do fully understand the importance of screening on low signal cables.

I also want to thank you (Your Company) for the very fast and good reply to queries and also with the customs. I will for sure keep recommending your cables to whoever I meet and have already done so to a few. Thanks to you and I wish you all a Happy New Year and hope 2015 will be a good year for your company.”

Best Regards,

“Finally, inserted in the main audio chain, they have shown they have little fear of top competitors. Without making think that these little serpents have equalled the performance of a cable that costs twice as much, I must admit that I was surprised by the level of performance.

They have had a lot of good reviews because they are worth it and keep their promises: I am stepping up to the chorus and I tell you to go and listen to them.

I would buy them because they are fine, I would buy them because they are absolutely inexpensive and I would buy them because they are discreet and not intrusive.”

– Di Dimitri Santini, Fedelta del Suono

“The Tellurium Q Black II speaker cables better the original Black in a number of important areas. The first aspect of these differences I noted was a more dynamic presentation. Impactful music, like the “I’m loving this record” Have fun by Smerz, exhibits greater impact from the opening wallop on opener “Worth It”. The degree to which the II convey this improved slam-ability over the Black made me sit up straighter in my red Eames LCW, which in and of itself promotes good posture, and think “Wow!”

– Michael Lavorgna, Audio Stream

“Thanks for the email. It does sound like you put a lot of work into repairing the cable for which I thank you, very much indeed!

I have received the cable back and it really finishes off my system well. I have Tellurium Q Black running through the whole hifi now and it sounds amazing even though burning in has not really finished in the cables yet. The sound is smooth and detailed and tonal balance of the music is just right.

Can I just say a big thank you to all you guys at the company for manufacturing such an amazing set of cables, and to you personally Geoff for the customer service you have provided me over the last week including the phone call to inform me of the work you had done with the repair. Its great to buy British products that are backed up by excellent customer support.

Many thanks again for fixing my cable, I may even take the day off work tomorrow just to listen to music!”

All the best

Best Regards

“This is definitely a big win for Tellurium Q’s Geoff Merrigan and company. To state it plainly; there is not a speaker cable that I have heard that comes close to the Black II’s performance and whose cost roughly translates to less than $150/meter. The cables are not big or thick but are built very nicely and come with your choice of bananas, spades or both. Tellurium Q plays it close to the vest when it comes to technical information, but as far as sonics go, I was greatly impressed by their performance. I spent a lot of time crawling around between my speakers and amps, swapping them in and out and back in because I could not believe how well they performed. They performed equally as well on planar speakers as they did with dynamics. I found their sound to be smooth over-all, with an open and airy top-end, and with extended bass and a slightly warm midrange.”

“I have just put Tellurium black interconnects into my system and have found even prior to ‘burning in’ they are stunningly coherent. There is a balanced presentation which exudes detail but does not render any part of the sound overblown, no part of the presentation audibly overshadows another part. This coherence is critically important.

All too frequently high cost within the system comes with the caveat that the system might be too revealing i.e. it may show some some vinyl and CDs to be poor quality either in pressing or recoding production. Whilst there is some logic in this, no one wants to render any part of their music collection unlistenable. Tellurium black is hugely revealing but its presentation is not brittle, it is a cable for people who like music.

Tellurium really does present as if it is a cable for the people and that is the highest accolade of all.”
