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.

Reviews and User Comments

Pursuit Perfect System

“Fantastic analogue cables from the bottom of the range to the very top. The time I spent with the entry Black II speaker cables was a standout moment for me this year [2018]… absolutely outstanding value for money… really this award goes to Tellurium Q as a company in general but specifically for the Black II speaker cables. They are definitely the Pursuit of Perfect Systems best analogue cables of 2018”.

“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.”

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

Twittering Machines

“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..”

Fedelta del Suono

“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 Read the full review

Audio Stream

“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 Read the full review

Stereo Times

“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.”

“If you compare it to other cables, even my previous ones, by a well-known American company, you can get the impression that other producers are combining how to stand out from the crowd, and Tellurium combines how to best give music back.”

“I changed to the Black II after a few tracks and was so flabbergasted by the improvement again that I didn’t bother going back to the Black.

It really was night and day. What struck me the most was how natural and clear the cable sounded with no nasties or obvious short comings. Now I know it can’t be perfect, and Geoff told me wait till you hear our pricier cables (oh dear), but I can’t remember hearing such a difference so easily, which makes my life a lot easier both as a reviewer and simply a listener. Isn’t that what good kit should be about.”

“Black II is a completely different cable than Black. .. The smoothness of this cable is unique. Looking at both cables, not knowing that you need to look for a Roman “double” on a black outer jacket, we would say that they are the same cables. But let’s listen to them with a few songs, it does not take much time to come to the conclusion that really big changes took place between the new and the old version.”

“..the Black II is a no-brainer compared with the original cable. It is really superb, whatever it is made of. …..the presentation becomes fuller and more rounded. The bass is also much fuller and yet more controlled than with the older cable.”

“Alongside the Black IIs I also received

a set of the original cable for comparison – and the step-change in performance is apparent. Improved tonality was the first thing that struck me, especially with acoustic instruments. Keith Jarrett’s piano on ‘The Carnegie Hall Concert’ had more body and weight to it with a rich, resonant presentation. Here was the sound of a real instrument playing. While the original Black cable was good this new version takes all its qualities and builds on them with a sense that it is letting even more of the musical information through. Timing, especially, seemed better and more focussed with a total absence of smear or haze around instruments. An update to an already outstanding loudspeaker cable, the new Black II cables improve on the originals to a remarkable degree.”

“The bass is very good – accurate, fast, not monotonous, even in the bottom border. Attack is fast, feeling that improved damping acoustics. The sound in general comfortable: a lot of details that do not detract from the overall musical picture.”

“…offers insight into the way the instruments are being played. That is rare at this price. This is a very communicative, engaging and capable presentation, making it the most natural thing to just forget about listening to the system and simply enjoy the music.”

Performance Profile

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.

A Fantastic Power Solution for Older Homes with Limited Outlets ⚡🏡🔌
Size: 5FT, Color: White 2prong
Living in an older home often means dealing with outdated two-prong outlets and a frustrating lack of convenient charging options. This 2-prong extension cord and outlet adapter solves that problem beautifully by converting a polarized two-prong outlet into an incredibly versatile charging station with 11 AC outlets and 6 USB ports. 🏠✨📱 I have been using this type of power strip in areas where only older two-prong outlets are available, and it makes a tremendous difference. Instead of relying on multiple adapters and extension cords, everything can be plugged into one compact unit. 🔌💻📺 Whether charging phones, tablets, laptops, lamps, and other electronics, this power strip keeps everything organized and easy to access. The standout feature is the impressive 17-in-1 design. With 11 AC outlets and 6 USB ports, including 3 USB-C ports, it can power and charge a large number of devices simultaneously. 📱💻⌚🎮 The USB-C ports provide fast charging for many modern devices, which reduces the need for separate charging bricks and helps minimize clutter. I especially appreciate the thoughtful outlet layout. The three-row design provides generous spacing so larger power adapters do not block neighboring outlets. 🧠🔌👌 This makes it easy to use nearly every outlet at once, which is extremely useful for office setups, entertainment centers, and bedside charging stations. The five-foot extension cord offers excellent flexibility, and the flat angled plug fits neatly behind furniture without protruding too far from the wall. 🛋️📏✨ This is particularly helpful in tight spaces such as behind bookcases, sofas, and nightstands. The built-in mounting holes are another nice touch, allowing the unit to be securely attached to a wall or desk if desired. Safety features are also reassuring. With surge protection, overload protection, short-circuit protection, and fire-resistant construction, this power strip is designed to handle daily use with confidence. 🛡️⚡🔥 Knowing that connected electronics are protected adds significant peace of mind. For anyone living in an older house with two-prong outlets, this adapter offers a practical and highly efficient solution. It instantly modernizes outdated electrical access and provides abundant outlets and charging ports in one organized unit. 🏡🔌📱 Overall, this is an exceptionally useful power strip that combines convenience, charging versatility, and robust safety features. With 11 outlets, 6 USB ports, fast USB-C charging, and compatibility with older two-prong outlets, it is an excellent addition to any home, office, dorm room, or gaming setup. ⚡🏡🔌💻📱✨

2 prong to 3 prong power strip. Devices share common ground bus. Green light on switch. Compact plug
Size: 5FT, Color: White 2prong, Size: 5FT, Color: White 2prong
This power strip has no ground. It allows you to plug a 3 prong device into the strip which has a 2-prong plug going into your outlet. You'll want to make sure you understand the implications of that if you use this. For my use I'm using the power strip to have the convenience of using my 3 prong extension cords for ungrounded devices. The power strip is composed of the main body with 11 outlets plus 3 USB and 3 USB-C ports. There's a switch to turn on or off the power switch and the switch has a green light when turned on. On the back side are holes for optional surface mounting as well as the power ratings. The USB ports are all standard 5V ports. While the ground plug on the 3-prong outlets is not connected through the power cord the outlets on each side share a common bus on the power strip itself. Thus if any device plugged in on that side has power going into the ground prong it will energize the ground on all devices connected with a ground prong on that side. The body measures approximately 8.125" by 4.125" by 1.25" thick. I weighed the power strip with cord at 15.38 ounces. The power cord is approximately 4.9' long with a compact right angle plug. The plug is polarized meaning you cannot plug it in inside down. Looking at a 3-prong plug if the ground prong is at the bottom the cord goes down to the right at about a 45 degree angle. The plug is compact and you can plug 2 of these in on the same 2 outlet wall outlet. The cord is printed with the wire information and contains 2 16 AWG conductors. The rated power seems appropriate for the size of the power cord. The outlet looks and feels nice and handles a lot of devices.

Good value for a high quality product with some possible safety compromises
Size: 5FT, Color: White 2prong, Size: 5FT, Color: White 2prong
This power strip is a practical solution for anyone living in an older home that still has two‑prong outlets. Many older houses were built long before grounded wiring became standard, so finding a way to expand your available outlets without rewiring the entire room can be a challenge. This adapter is designed specifically for those situations, and it provides a surprising amount of capability in a compact unit. Before using it, I wanted to be sure it was safe to plug a three‑prong device into a two‑prong outlet. It is legal to use an adapter like this in the United States, but only when you understand its limitations. A two‑to‑three‑prong adapter does not create a true ground. The product page notes that this model is built to UL 1363 standards and includes surge and overload protection, which helps add a layer of safety for older outlets. Still, it is not a substitute for proper grounding, and anyone who wants full protection should eventually have an electrician install grounded outlets. As for the device itself, it is well designed and easy to use. The main body includes 11 outlets, along with 3 USB ports and 3 USB‑C ports for charging phones, tablets, and other small electronics. All USB ports are standard 5V. There is a power switch with a green indicator light, and the back of the unit includes mounting holes if you want to secure it to a wall or desk. The size is compact—about 8 inches long, 4 inches wide, and just over an inch thick—so it fits neatly in tight spaces. Overall, this is a good value for anyone who needs more outlets and charging options in a home with older two‑prong receptacles. It offers convenience, versatility, and thoughtful safety features in one organized unit.
