Question: I am experiencing some air noise from the tube holes in my speaker (a bit like driving in a car on a highway with open windows). Any solution to this problem?
Answer: This is something typical for bass reflex speakers. When you play music with very low frequencies at high volumes there is a lot of air motion, which can cause these noises. If you play music with also higher frequencies you won't hear it anymore. The only thing you can do is put something into the reflex tubes and "close" them. But if you do so you will loose some bass response. This is something that cannot be avoided when using bass reflex speakers.
Answer: With the Phase Switch you can alter the phase of the subwoofer relative to the satellites. That means to change the polarity of the bass unit. Depending on the distance between woofer and satellites, either 0° or 180° may be the better position.
Again, the best way to find the appropriate settings for your system is to try what position sounds better.
Question: I have purchased a subwoofer in addition to my pair of main speakers. Here are some questions regarding the set up:
- What crossover frequency would you recommend for the subwoofer? Would you recommend to connect the speakers through the subwoofer or should they be connected seperately to the audio interface? If I go for the first option, will there be any loss of quality?
- If I change the crossover frequency of the subwoofer, does that mean to change the seperation frequency of the speakers?
Answer: Generally, it’s hard to tell what settings of a subwoofer to choose. The impact of the specific room (dimensions, symmetry, furniture, etc.) plays quite a huge role. After having chosen the position of the subwoofer, it is advisable to try, try, try…
- All our subwoofers are equipped with an active bass management and include a “Satellite Filter” with which the speker’s lower cut-off frequency can be set at 85Hz. If you choose to use the filter, we recommend to set the subwoofer’s frequency to 85Hz, too (this is the factory setting). With smaller speakers/monitors, higher cut-off frequencies might be advisable (appr. 100-115Hz). Should you decide to go for a higher cut-off frequency, it might be good to connect the subwoofer and the satellites individually to your audio interface. By doing so, you can set the cut-off frequency for the satellites separately.
- There will be no loss of audio quality if you choose to connect the satellites through the subwoofer. Also, there will be no effect on the frequency of the satellites by changing the frequency of your subwoofer.
Question: The newer ADAM monitors do not have a magnetic shielding any more. Why?
Could this cause any problems with other technical equipment?
Answer: Almost all loudspeakers – and without exceptions all ADAM speakers – use permanent magnets which generate a constant magnetic field. In the age of the CRT monitors, it was necessary to shield the speakers magnetically to avoid interferences between the two devices.
The newer ADAM models are not equipped with magnetic shielding because hardly anyone is using CRT monitors these days.
However, precaution is still recommended when it comes to magnetic data carriers (e.g. hard drive, credit card, etc.). We would advise you not to put these too close to the loudspeakers. At a distance of about 30cm there is no longer a considerable magnetic field.
Answer: This is one of the most frequently asked questions and a common misunderstanding.
No, the ADAM propriatary Accelerating Ribbon Technology is not what is generally understood by a ribbon tweeter since the diaphragm is not a ribbon but a folded foil. The term 'Ribbon' as part of the name of our technology only refers to the material but by no means to the functionality. For a more detailed description of this technology, please click here.
Answer: Yes you can. If you choose to use your speakers in horizontal position, please make sure that the set up is mirror symmetrical, i.e. that the tweeters both face either the outsides or the insides. This is crucial for a precise stereo signal.
Answer: All new ADAM speakers (SX models or newer) show an input sensitivity of 100mV - 90dB SPL 1m. The older models vary. The A7's value of 100mV - 87dB SPL 1m can be cosidered to be an average value.
Answer: Loudspeakers include movable parts. Therefore, they need a certain 'burn-in time' for a full excursion and adaption of these parts. After this burn-in time, the speakers reach their full acoustic potential.
To break-in your speakers, it is advisable to feed them with music signals of a broad frequency spectrum and different volumes for a certain period of time:
Up to one week for a 'normal' burn-in.
Up to four weeks for a reliable long-term consistency.
However, no responsibility can be taken for the correctness of this information since it always depends on both frequency and sound pressure level of the speakers usage. Furthermore, the real time a speaker needs to burn in is, to some extend, always due to the specific speaker itself.
Question: The ADAM speaker I have bought features both XLR and RCA connectors. Is it possible to use both at the same time, i.e. to have two different sources connected to the speaker using both connectors?
Answer: Yes, that is possible. If you use both the XLR and the RCA connectors at the same time, please make sure that only one of them transmits a signal at a time. If the speaker receives signals via both connectors at the same time, the sound will be degraded (you will hear both sources simultaneously).
Question: I have bought ADAM speakers in one country but use these speakers in another country. Is there an international warranty that covers service/repair?
Answer: Should service be required, please contact the ADAM Audio dealer where the product has been purchased.
If the equipment is being used outside the country of purchase, the international shipping costs have to be paid for by the owner of the product.
Service may be supplied by your ADAM Audio national distributor in the country of residence. In this case, the service costs have to be paid for by the owner of the product whereas the costs for parts to be repaired or replaced are free of charge.
To validate your warranty, you will need a copy of your original sales invoice with the date of purchase.

Question: I can see some damping material at the end of the bass reflex tube of my speaker. Could that cause a problem?
Answer: No, usually this won't cause any problems. However, it is possible that parts of the damping material have been shifted while transportation. As long as the material does not interfere with the air flow through the tube and you cannot hear any degradation of the sound, everything is fine.
Answer: It is common knowledge that low frequencies (below about 100Hz) are non-directional, meaning they can hardly be located by the listener. It is, however, a common misunderstanding that therefore the placement of a subwoofer does not matter. It does matter. Due to the fact that every room (geometry, furniture, etc.) is unique, the following descriptions intend to be a first introduction to the subject. The aim is to assist you tackling the most common problems with subwoofers and room acoustics, notably interference and standing waves.
1. Distance to satellites: In most set ups it is advisable to place the subwoofer not too far from the satellites to minimize the chance of Interferences. Interference means the superposition of two or more waves resulting in an attenuation/cancellation or enhancement of the specific frequency/frequencies. Furthermore, big reflexion faces in close range of the subwoofer should be avoided if possible.
2. Walls/Distance to walls: Generally, every wall in relative close distance to the subwoofer enhances its sound pressure by about 6 dB. For instance, placing the subwoofer in a corner of a room will make it about 18 dB louder. It is likely that this will result in an impairment of the precision of the musical reproduction. Another problem related to the geometrics of the room concerns the so called ‘standing waves’. These are sound waves being reciprocated between reflecting objects, so they ‘stand’ (don’t seem to move) in between these objects. The speaker continues to produce new waves that combines its force with the first wave(s): a vicious circle that results in local imbalances of the particular frequencies.
3. Give it...a try! The most important tool for finding the best position for your subwoofer are your ears. There are two rather easy ways: You can determine your listening spot first and then compare the sound of the subwoofer at different positions. Another option is to place the subwoofer at the listening position and then move around. Whereever the sound is the best the subwoofer should be positioned.
