Sufficient power for shelf and small floor-standing speakers

The CoreStation Compact delivers 2 x 40 watts RMS from a highly efficient and extremely low noise class D amplifier from Texas Instruments. Fill rooms up to 25 m² with high, distortion-free levels.

Fits behind the TV set

An included sturdy steel TV mount makes it possible to attach the little CoreStation Compact behind your television. You can even place the CoreStation in a drawer – it will still react to commands from your remote.

The completely passive construction uses no fans for noiseless and trouble-free operation.

No fan - no operating noise
The completely passive, fanless construction on a solid aluminium base guarantees silent and maintenance-free operation.
Works with wireless subwoofers

The CoreStation Compact has an integrated wireless module. This makes it possible to communicate with a wireless subwoofer such as the T 4000 or any standard sub equipped with Teufel’s Subwoofer Wireless Receiver. The signal will be sent wirelessly, losslessly and without discernible latency.

Bluetooth 4.0

The CoreStation Compact uses Bluetooth with the sophisticated aptX codec. This makes it possible to stream music via Bluetooth in a sound quality that cannot be distinguished from a cabled source. Simply activate Bluetooth on the system and the CoreStation will transmit all the audio from your mobile device to your speakers. Enjoy music from Spotify, YouTube and iTunes as well as audio from Facebook, apps and games in pristine sound quality.

Flexible controls

The CoreSation Compact can controlled in a number of different ways. Use the Puck Remote, your own TV remote or the controls on the device itself. The eco-friendly little system automatically shuts itself off after 20 minutes with no in-coming signal.

Flexible playback options

The CoreStation Compact offers an HDMI input and an analog RCA input. Any additional HDMI devices can be connected directly to your television. The sound from these devices will pass from the HDMI cable to the CoreStation Compact. Outputs include a high level connection as well as a subwoofer RCA connection for running 2.1 speaker systems.

Help regarding this product
My Bluetooth speaker produces a lesser quality sound with my Windows PC or laptop.
It could be that the speaker is connected as a device with speakerphone function. Please go to: settings menu > devices and printer > BOOMSTER (or other Bluetooth device). Right click on the device and remove the check mark next to the “speakerphone” option.
How must I set the impedance selector switch of my receiver for Teufel speakers?
Here is more detailed information from the AUDIOVISION trade magazine (Issue 4/03) on the subject of impedance settings of the AV Receiver:

Actually, it should be quite simple: Connect the speaker cable to the amplifier and speakers with the correct polarity and you're done. Unfortunately, many manufacturers of home cinema receivers put stumbling blocks out for the users in the form of specifications on the rear of the device and/or in the operating instructions. These usually look like the following (translations): Minimum connection impedance six ohm! Or, speaker impedance six to eight ohm. And what is the problem? There are hardly any six ohm and only a few eight ohm speakers available in Germany. Most of the speakers sold in Germany have a nominal impedance of four ohm. So theoretically, you shouldn't connect them to most of the receivers and amplifiers.

To explain why it is possible after all, we would like to briefly explain the electrical engineering principles: The impedance of a speaker is nothing other than its electrical resistance which it puts up against the flow of current.

• Low resistance = high current
• High resistance = low current

Important to know for operation with an amplifier is that the impedance is not the same for all frequencies but can, for example, change between 50 and 200 hertz by 50 percent. So it isn't entirely correct to speak of impedance for a speaker per se, rather one must always consider the behaviour across the entire range between 20 and 20,000 hertz. To still achieve a reasonable connection value for amplifiers (which, by the way, says nothing about the output impedance of the amplifier itself but rather only which impedances may be connected to it), the creators of the DIN Standard have applied the following stratagem: Only the minimum value of the impedance in the audible range is decisive for the nominal impedance value. This is where the most current flows and the amplifier is subjected to the highest load. Speakers with eight ohm nominal impedance may only exhibit a minimum of 6.4 ohm, and those with four ohm nominal impedance 3.2 ohm. Six ohm are not defined in the DIN (which is applied internationally), but one could use the above values to interpolate that they may exhibit a minimum of 4.8 ohm.

From the definition it is apparent that the nominal impedance is only a rough benchmark, because it says nothing about how the entire course of the impedance looks. No matter whether it only reaches less than 6.4 ohm at one point and is otherwise beyond that, or if the impedance moves close to 3.2 ohm across the entire range, but does not drop below that. The last speaker is surely much more stressful for the amplifier, but has just a nominal impedance of four ohm as the other higher ohm one.

Conventional speakers usually exhibit one to two minima in the bass range, and there is one frequently in the treble range. These minimum values are usually not especially broadband. Aside from the minima, the impedance is usually far higher than the nominal impedance. The amplifiers are really stressed in the bass range because firstly, this is where the most energy is for music and especially the home cinema sound, and secondly, they have to let the most current flow through the impedance minima here.

And lastly, the main reason why many manufacturers don't want four ohm speakers to be connected: In extreme cases - for deep frequencies of consistently 3.2 ohm - the amplifiers in multichannel operation become very hot. A lot of current also means a lot of power loss and thus at lot of waste heat. However, much has to come together before that happens - namely high performance for a longer period of time and setting up the device without sufficient ventilation.

But this extreme case is seldom met in practice. As mentioned above, most of the speakers are not as critical by far, and it is extremely rare to listen to an exorbitant volume for a longer period of time. That is why it is not a problem from a technical point of view to connect speakers with four ohm nominal impedance to all modern home cinema amplifiers and receivers.

However, there is one small catch: The question of warranty. Should a defect occur to the device - which doesn't even have to do anything with the speakers - and the manufacturer notices that four ohm speakers were connected despite the specifications to the contrary, he could refuse repairs due to improper use. As discussions with manufacturers and distributors have shown, this is highly unlikely because they are also aware of the problems.

And for purely legal reasons, Lautsprecher Teufel may not give you a warranty either that your amplifier or receiver will tolerate four ohm speakers. We can only pass along one experience: For several years, the listening tests of the trade magazines are done exclusively with four ohm speakers, and not a single defect has occurred as yet even though the devices are driven to their limits. Also, the performance of each device is usually measured at four and eight ohm irrespective of the specifications of the manufacturers, and the load here is also considerable. It has been a long time since measurement laboratories have seen failures due to to low load impedance.

There are still some special cases, which should be briefly mentioned: Amplifiers/receivers with impedance switches give cautious natures the possibility to stay on the safe side under all possible conditions, even with the warranty. The four ohm setting of the corresponding switch reduces the supply voltage of the power amplifiers so much that excessive heat cannot occur even under unfavourable circumstances. However, the maximum power is then reduced somewhat.

During the listening tests of the trade magazine, these devices are always switched to the "eight ohm" setting to tease out the maximum performance reserves. A defect here has yet to occur. When choosing devices, take a close look because there are devices that only permit speakers with a minimum of six ohm despite the impedance selector switch, like the Pioneer VSX-D2011, for example. This is remarkable in another respect: It possesses a THXSelect license. This license is only issued if certain measured values are complied with that are determined at four ohm for at least the front and centre speakers.

If the THX laboratory had proceeded according to manufacturer's specifications, the VSX-D2011 would never have received a licence, as it would not have been permitted to perform the necessary measurements. By the way: this is also the case for other THX Select devices. But you needn't worry here: The THX logo not only offers additional security, but also a good lever should a manufacturer once refuse a warranty.

The AUDIOVISION TIP

Overheating is the main problem that can occur through the combination of four ohm speakers with power amplifiers that are not released for this.
Therefore, in case of doubt:

• Always set up the AV Receiver or amplifier in well ventilated places and never in a closed housing or close to the heater.

• Occasionally check the temperature of the device.

• Reroute the bass elements via set-up at the subwoofer, if possible.
Can I operate Teufel speakers with an amplifier with 6 ohm outputs?
Without problem!

The fact that some amplifier manufacturers give corresponding information is founded in the VDE standard. To comply with this standard, the devices may not become hotter than 40°C above room temperature so that no one is injured when touching the amplifier.

These 40°C are only reached in the threshold range, meaning for very great volumes for a longer period of time. There is no danger of overloading the amplifier during normal operation. The higher temperature that occurs when connecting 4 ohm speakers will not damage the device in any way. Therefore you can connect 4 ohm speakers without reservations.
Can I order the Teufel speakers in different colours than those offered?
To realise the very reasonable sales prices usual for Teufel, it is not possible to offer the speakers in a multitude of housing designs.

This circumstance would drive up the production and storage costs, which would result in a significantly more expensive sales price.

A paint shop in your vicinity will surely be able to repaint the speaker housing to your preferred colour without loss of warranty - after expiry of the eight-week right of return.
I would like to connect the appliance to a record player, is that possible?
In principle, yes.

However, for a record player an additional phono preamplifier is required - these are available from specialist retailers for around €50.
What are the technical requirements for an AV receiver to function with RearStation 4?
The AV receiver must be able to send signals to the rear channels via a pair of cinch terminals. Generally these terminals will be identified as Side, Rear, or Left/Right. It is often also possible to "activate" channels on specific terminals by means of the AV receiver menu.
Can I also connect a 6.1 speaker system to a 7.1 AV Receiver?
No problem.

A 7.1 AV Receiver merely provides the possibility of utilising a 7.1 speaker system; it is not, however, a mandatory necessity.

That is why you can only use a 6.1 speaker system with the 7.1 AV Receiver. In the "Speaker Set-up" menu of the receiver, you frequently only need to specify which of the two channels will be addressed as rear centre.
