Sony XS-FB1030 4" 3-Way Mega Bass Coaxial Speakers

Suena bien.

The speaker measures 4 inches, with the cover on, it measures 5.5 inches. The speakers perform well, I connected them to an indoor stereo system at full bass capacity and it has really good base and treble. These speakers perform well. What I decided to do in the car stereo was to splice the rear speakers and use it's radio signal, in this way of wiring it to did well. The difference to the home system and the car radio was that, the home system has mega bass system feature integrated to it's options that's were it showed it's true mega bass capability. In the car radio, the bass was less because it's a stock radio, the Sony speakers performed well on the treble, providing clean vocal singing. At the end, unlike these speakers because they make my car audio sound clean and enjoyable. If you don't have a stock radio, these speakers are likely to provide more bass and perform at it's given specs. This product is true to what it advertises.

El sonido no tiene nada de malo al parecer , lo que sí estuvo muy mal fue la entrega ya estaban abiertas y la caja (de adentro) estaba en muy mal estado

The extra bass promise is complete nonsense, it sounds reasonable. Don't expect miracles.

Installed in doors of 1998 Audi A4 to replace the original factory speakers. I had to drill a couple holes to mount them, but it was not hard at all. The speakers were basically plug-n-play once they were installed. I have these speakers connected to a Sony head unit and they sound very good for their size. They don't have deep, booming bass, but it's adequate.
