6.5" (16.5cm) bass-midrange driver

All about 6.5" (16.5cm) bass-midrange driver

Mid-bass drivers are - as you can easily guess - a combination of midrange and woofer. In a 2-way system, they naturally take over the midrange frequencies, but they also have to deliver good bass. As a rough guide, it can be stated that mid-bass driver cover the range from 40 to 5,000 Hz, although these are not exact limits. Our top seller "Pride M6.5" covers about 80 - 4,000 Hz, while the also very popular "EDGE Car Audio EDBPRO6-E9" only gets going at 105 Hz and then reaches heights of 10,500 Hz.

Mid-bass driver for 2-way system

Due to the different frequency ranges, it is necessary to optimally match the desired system. In this respect, 2-way systems can certainly hold a candle to the often proven 3-way systems. The general statement that a 3-way system with tweeter, midrange and woofer is superior to a 2-way system consisting of bass-midrange driver and tweeter is superior to a 2-way system consisting of a woofer, midrange and tweeter. A well-designed 2-way system with high-quality components can offer very good results. In individual cases, it can even be the better choice and is also the cost-effective alternative in many cases. Space requirements should also not be forgotten: If space is limited, a high-quality 2-way system may be the optimal choice.

Clear mids and full lows

Although mid-bass drivers are also often referred to as mid-woofer the former is the more common term. In any case, these drivers must reproduce the mids as well as the lows well. The mids correspond to the frequencies that we know well from our everyday life. Human voices as well as natural sounds take place here, as do many instruments. Thus, our human hearing knows these frequencies very well. We intuitively recognize distortions and are very sensitive to bad sound experiences. Good mids are the basis for a full and true sound experience. A mid-bass driver therefore has the task of reproducing the mids clearly and distinctly, while at the same time providing the richest possible bass. After all, the bass is the measure of all things for many sound lovers. The popular kick bass also falls under the remit of the mid-bass driver. If you're wondering what kick bass is, kick bass falls in the higher bass ranges at frequencies of about 50 - 200 Hz. It is a very dry and "kicking" bass, which can be particularly important depending on the music style.

Popular dimensions and brands for mid-woofers

16.5 cm outer diameter is the most common size for mid/bass drivers. It is considered the unofficial standard and is easy to install. The size is also often given in inches; in this case 6.5 inches (6.5"). In principle, however, other sizes also exist for mid/bass drivers and we carry drivers from 4 inches to 15 inches or 10 cm to 38 cm. In recent years, it can be observed that larger speakers are becoming increasingly popular. Nevertheless Midrange woofer with 165 mm diameter are still a good choice. If you are in danger of getting lost in the selection, we can recommend four established brands: Pride AudioVibe Audio, Deaf Bounce, Audio System. A speaker from these brands is an asset to any sound system.

The optimal woofer: key figures

The choice of woofers differs not only in price, size and frequency range. An important key figure is certainly also the power, especially the averaged power (RMS). A solid value for many purposes is 120 watts RMS, whereby the connoisseur of softer sounds can also be happy with 60 watts RMS. If you want to go to the limit, you'll also find speakers with 250 watts RMS. The impedance, which is all too often neglected, should not be forgotten.

Our pro tip:

Loudspeaker and amplifier should have the same impedance value. If the loudspeaker has a lower impedance than the amplifier the latter may be damaged in the worst case. Conversely, if the impedance of the loudspeaker is higher than the impedance of the amplifier, the loudspeaker will not perform to its full potential. Although most bass-midrange drivers have an impedance of 4 ohms, this value should also always be kept in mind.

Which manufacturers does Masori distribute?

Sound lovers do not want to spend their time with bad sounds. The optimal interaction of the components must therefore be chosen carefully. There is no right or wrong here. The personal feeling plays an essential role. With a bass-midrange driver with 165 mm diameter is the first step towards the perfect sound experience.
