After my initial experience with the BlackGround Power Base 10x in February and March, I had my doubts that another one of these beautiful wooden boxes would help. In fact, did I need any help? The answer turned out to be yes - indeed. The areas the 8x Speaker Base has improved are darker background, focus and imaging. With the Speaker Base, I can now fully enjoy choral works. Individual voices are laid out in the soundstage. - plus - all of the reverberations are better heard. It sounds quite amazing! In addition, when unpacking and installing, I enlisted the help of my wife, who commented: "wow that is a nice looking piece. It sure looks better than a black piece of metal."

Congratulations on the Speaker Base!! I feel it’s your most impactful product thus far! It’s uncanny! This is the first 'tweak' that diminishes that subtle 'edge' and grain (that I thought was implicit in streaming/digital). While that sounds small, it is the first time I can hear the sweetness and tonal color of a violin and massed strings; also the noise floor has dropped (equivalent to QSA Silver levels - big!), allowing me to hear things I never heard before, and the subtle timing cues that communicate emotional intent. Last, space - the soundstage has expanded, and instruments are just 'there' (hearing the hall sound more explicitly - indeed the decays are magnificent!). Small sonic changes but huge musical gains. I hear NONE of the softness that 6 Moons heard from the mains Blackground (indeed, I don't hear that with mine) - to my ears, 'PRAT' and emotional involvement have improved! I get however that some might hear less 'edgy' transients - but to me, that is more natural and realistic.
We'll, I must admit I wasn't prepared for how much the Blackground 8x Dual Channel Speaker Base would contribute to the already spectacular 10x Power Base. From the moment I heard the first track, I knew I was in for treat. It's as if you're able to reach out and hold each note & vocal in your hands. Never has the listening experience felt so tactile. Now if you'll excuse me, I have to pick up my jaw from off the floor!

BlackGround 10x Speaker Base - Single Channel


LessLoss BlackGround 10x Power Base

Single channel means that you will have all 10 onboard BlackGround modules available for a single loudspeaker signal. A single loudspeaker signal is made up of both positive and negative polarities (Red and Black terminals accordingly on your amp or speaker posts).

So, if you will be using this single channel version on your stereo set of speakers, you will need two of these units. One for right channel, one for left channel. We will sell these at a 5% discount on both if you get them together.

A bird's eye view

Here's the unit from the top.

LessLoss BlackGround 10x Power Base

As you can see, there are two terminals at the back which are not present in the 10x Power Base version.

Now let's zoom in for a closer look at these.

LessLoss BlackGround 10x Power Base

The two terminals on the right are exactly as in the 10x Power Base. They are simply at ground potential, and marked with ground symbols accordingly. There are two so you could bridge one unit to another with a grounding cable. This keeps you from needing to use additional power cords on each unit for grounding purposes. You can simply ground it into your 10x Power Base using these terminals and a grounding cable. Nice and elegant.

However, there are two new terminals on the left. These are for the tapped speaker signal. You can tap these from either your amp's terminals, or from your speaker terminals. As these units will likely be placed closer to your equipment than to your speakers, you will probably want to use the amp terminals. But either way is just fine.

Now let's zoom up even closer.

LessLoss BlackGround 10x Power Base

I turned the unit around on the table. In the center of this picture you see the negative terminal. It is marked with a "—" sign in the circle there. This is where you connect the black terminal of the amp to.

LessLoss BlackGround 10x Power Base

Now you see the "+" marked terminal. This is where you connect the Red terminal from the amp.

Basically you only need our Large size Grounding Cable product for these two connections. We will easily customize these for you with Black and Red markings free of charge. Just ask.

LessLoss BlackGround 10x Power Base

Here are the two Ground terminals marked with the ground symbols. These are at the exact same potential as the grounding pin on the power inlet you see on the left. Again, you don't even need this power inlet if you are grounding this unit by simply bridging the ground over from the 10x Power Base over to it. Just use a Large size Grounding Cable which we offer. It is not expensive at all, and performs incredibly because it is a C-MARC™ cable.

If you don't have a 10x Power Base and you want to use this unit anyway, you can use any power cable you wish to provide ground potential. The idea here is that the power inlet you see pictured is only connected to the grounding pin inside the unit. The other two pins are not even connected. This way, there will never be any danger of introducing power voltages into this unit, which is meant only for your speaker signals and ground potential.

So, there you have it! Here's the unit from the front.

BlackGround 8x Speaker Base - Dual Channel


So now let's take a look at the 8x Dual Channel version for speaker signals in detail. On the top we see the laser engraved insignia:

BlackGround 8x Speaker Base - Dual Channel

This means that this unit has 8 BlackGround modules onboard, and has provision to condition two audio channels of speaker level signal.

Just like the 10x Single Channel version, the form factor is the same as our 10x Power Base. So it looks like this:

BlackGround 8x Speaker Base - Dual Channel

And it also features the hand made brass placard on the front:

BlackGround 8x Speaker Base - Dual Channel

Now let's turn it around and take a look at the connections:

BlackGround 8x Speaker Base - Dual Channel

From left to right, we see the IEC C14 inlet for any standard power cord, two ground terminals for banana connections, and then four speaker signal input terminals labeled +, -, + and -.

Now I'll explain how simple it is to connect. We'll divide the explanation in two parts.

Part 1: The Grounding Connection. (It is circled below.)

BlackGround 8x Speaker Base - Dual Channel

You've got two choices. You can either use a standard grounded power cord, or you can use any of the two grounding terminals which have the ground symbol on them.

So for instance, if you already have the 10x Power Base, you don't need a power cord for this one. You can simply run one of our C-MARC™ Grounding cables from a 10x Power Base ground terminal to any of the two grounding terminals on this one. The Grounding cable needs to have bananas on both ends.

But if you don't already have the 10x Power Base, you can also simply use any power cord which features a grounding connection and plug it in to your grounded wall outlet.

That's it for Part 1 (grounding).

Now we move on to...

Part 2: the speaker signal connections. (Circled below).

BlackGround 8x Speaker Base - Dual Channel

You see above four terminals reading from left to right: +, -, + and -.

The first two on the left are for one channel and the last two on the right are for the other channel.

You can tap your speaker signal from your amp outputs or from your speaker inputs.

So, in detail, let's quickly go through them, starting from the rightmost connection and working our way towards the left.

BlackGround 8x Speaker Base - Dual Channel

This one is negative, so we drew a black circle around it. This goes to the black output of your amp on one channel.

BlackGround 8x Speaker Base - Dual Channel

This one is positive, so we drew a red circle around it. This goes to the red output of your amp on the same channel as the black (negative) one you just connected.

We're done with one channel.

Now we connect the other channel. Negative (black) goes to amp's black output terminal:

BlackGround 8x Speaker Base - Dual Channel

And finally, positive (red) goes to amp's red output terminal for that same channel:

BlackGround 8x Speaker Base - Dual Channel

So that's all the connections you need to make. All of the wires going towards the BlackGround 8x Speaker Base - dual channel version are always banana terminated wires.

BlackGround 8x Speaker Base - Dual Channel

These are very nice terminals polished to perfection. The way they are intimately mated to solid wood, there's no ringing whatsoever and you can really appreciate this when you make the silky smooth connection:
