Product-specific questions

What difference do new speakers really make?

You'll find that replacing your factory speakers will make a noticeable difference. The music will sound crisper, more dynamic and closer to the original recording of the music and better than with outdated or inferior speakers from the car's factory system. Replacing speakers is also the most cost-effective upgrade you can make to your car stereo. And even the newer, factory-installed speaker systems, which may sound okay at first, are generally not designed to give you the kind of reliable, ear-friendly sound you can expect from a good pair of aftermarket speakers for years to come.

How much power do I need for my new speakers?

While manufacturers will specify a range of RMS or continuous power that is suitable for the speaker, the best results will be achieved by approaching or even exceeding the upper end of this power range. That is, a speaker with a lower RMS power range is better suited for use with a factory or aftermarket system, while a higher RMS range works better with an external amplifier. Typically, factory radios offer a power of 20-50 watts RMS. If you are using an external amplifier, you should choose an amplifier that is rated at the upper end of your speaker's power range. For example, if a speaker is rated for an RMS power of 100 watts, it will be close to optimum if your power amplifier delivers 100-150 watts RMS. It is better to overload a speaker than to underload it - the distortion that occurs when you push a low-powered amplifier to its limits is much more likely to damage a speaker than too much power. Rule of thumb: The RMS amplifier power per channel should be 1-1.5 times higher than the RMS power of the speaker.

Can my factory radio supply retrofit speakers with power?

In most cases, yes. Aftermarket speakers certainly sound better when they have a little more power, but most of our speakers sound good even with the factory power. Exceptions are tuned component sets and speakers with an RMS power of at least 150 watts or more. An additional amplifier should be used here.

Do speakers with a higher efficiency level sound better?

The efficiency factor says nothing about how good a loudspeaker "sounds". They only indicate how well the speaker uses the power. If you are using a factory system with low power, you should choose a speaker with a higher efficiency (90 db and above). Low-efficiency speakers can sound good, but they need a powerful amplifier to produce the required power.

Does the type of tweeter have an influence on the sound I hear?

Speaker manufacturers use a variety of materials for their tweeters, such as paper, silk, ceramic, aluminum, titanium, polyethylene and so on. One material is not necessarily better than another because they all have different properties and reproduce sound in different ways. As a rule, paper is more responsive because it is so light, while composites are more durable. You'll find that silk and silk/polymer blends sound very smooth and even, and metallic materials like aluminum and titanium sound very clear.

What difference do the membrane materials make?

As with tweeters, there is also a wide range of materials for woofers. They can be made of treated paper, aluminum, plastics or composite materials. Woofer cones need to be stiffer because they have to reproduce strong bass tones. Here too, paper tends to be less durable, but reacts more quickly than other materials.

How do coaxial loudspeakers and component loudspeaker systems differ?

With properly tuned component speaker systems, you get a better sound image and a much more detailed and dynamic sound than you can expect from conventional speakers. By mounting the separate tweeter closer to your ears, the imaging of the speakers is optimized and a richness of detail is achieved that you may never have heard before. The high-quality woofers deliver powerful, dynamic bass and midrange, while the separate crossovers properly distribute the highs and lows to protect your tweeters and keep your system sounding its best. Coaxial speakers are suitable in cases where there is no room for a separate tweeter in the car and you want to get the best possible performance from the existing factory speaker slots. Coaxial loudspeakers have a fixed tweeter directly in front of the woofer cone. They have a built-in crossover and separate high and low tones "automatically", making them very easy to install.

My new component speakers don't meet my expectations. Why is that?

Check the crossover setting - many people think that a flat setting for the tweeters is the way to go, but you'll often find that you need to cut the treble to compensate for too much brightness Do you have enough power for the speakers? Most speaker systems running through your radio will not have enough power to drive them properly. Remember, it's more dangerous to underpower your speakers than to overpower them. Like a good subwoofer, speakers need time to acclimatize. Give the speakers a few hours of break-in time to settle in. Are you getting rattling noises and vibrations? Check your brackets - you may benefit from fitting foam silencers and aluminum butyl insulation in your doors.

How do I know which speaker size I need?

Finding the right speakers for your vehicle doesn't have to be confusing. Masori has fitted thousands of vehicles over the years and has recorded them in databases so you can easily find out which speakers will fit your vehicle with the help of our support team. If you have any questions about the right speakers or would like to speak to one of our friendly advisors about speaker installation, you can always contact us. We'll be happy to help you find the right speakers.

Should I use universal loudspeaker systems or ones that are specially designed for my car?

With our loudspeakers in the "Vehicle-specific" category, you can rely on simple installation. For example, these systems are designed for 1:1 plug & play replacement of the factory speakers in your BMW, VW, Audio, Mercedes and other brands and have the same dimensions as the factory speakers. As a Masori customer, you benefit from free technical support via WhatsApp or email to help you find the right model. If you have a little manual skill, you can benefit from a wider choice and even better sound by using universal speaker sizes. The most common size of speakers for the doors are 16.5 cm speakers and speaker systems, which are often labeled with the size 6.5 inches. You can also find universal speaker rings in our store. The most common tweeter size is 1 inch, which corresponds to 25mm. These usually also fit with slight adjustments or with the help of small tweeter capsules on the original plugs or the A-pillar and the mirror trellis.

Do I need a crossover?

A crossover splits an input signal into two or more outputs with different frequency ranges so that tweeters and woofers only receive the frequency range for which they are designed. Frequencies outside the respective range are attenuated or blocked. Every loudspeaker system needs some kind of crossover. Component speaker systems come with separate crossovers, many with level controls for the tweeter. Every full-range coaxial speaker, where the tweeter sits in front of the woofer cone, already has a small crossover built in. Crossovers are usually small plastic boxes in which a circuit is hidden that splits the frequencies. All you have to do is connect the tweeters and woofers to the two connections marked for this purpose. The signal from the factory radio or amplifier is connected to the "amp" connection.

What is the difference between an active and a passive speaker set?

However, if you want to operate an "active" system, you need an amplifier in your aftermarket amplifier, which you can recognize by the frequency control on the side of your amplifier. Nowadays, all conventional amplifiers on the market have a built-in crossover. In an active sound system, each speaker (tweeter, woofer) has its own amplifier channel. This significantly increases the available power, the dynamic range (from the quietest to the loudest sound) and the control over the sound of the system across the entire audio spectrum. Almost all amplifiers have built-in high and low pass filters that can act as crossovers in a component system. The correct setting of the frequency ranges requires experience, and we will be happy to help you with this! In an exemplary active 2-way loudspeaker system with subwoofer in a car, the original audio signal could be crossed over as follows: The low frequencies (e.g. 80 Hz and below) go to the subwoofer. The woofers in the doors receive frequencies between 80 and 3,000 Hz. All frequencies above 3,000 Hz are handled by the tweeters. Bear in mind that the crossovers listed here are only an example and do not apply to every car or speaker system. The best crossover for one vehicle may not be the best for another. It all depends on the speakers used and the acoustic characteristics of the car.
