Massive Audio FX57 5x7 Coaxial Car Speakers | 180W Max Power, 8oz Magnet, 88dB Sensitivity – Premium Sound Upgrade for Car Audio Systems

We paired these speakers with a Pioneer GM-D8704 amplifier that supplies 100 watts per speaker at 4 ohms and the sound quality was excellent. The lowest frequencies were directed to a separate sub-woofer using a pass filter so these speakers were responsible for mid-high range frequencies. They handled the power very well without distortion. These speakers are also quite efficient and produce a high db/watt, therefore they will sound louder next to most other speakers while using the same power. This high efficiency was apparent when we paired various sets of other speakers simultaneously to the same amp along with the FX57s - all the other speakers were noticeably quieter using all the same settings for power and frequency range. One cautionary note is that the mounting depth is really 2.5 inches not 2.24 inches due to a mounting ring attached to the perimeter of the speaker that is not shown in the pictures. With some effort we removed the ring and tweeter cover and reapplied a thinner rubber ring and achieved a depth of 2.3 inches which was important for this particular installation. Overall, these are excellent speakers for their price point.

These sound excellent. Better highs, lows, and miss, than the Pioneer and Kicker 4" speakers I've previously had in the same location. To be honest I didn't expect much, but these are the best 4" speakers I've ever used. Even when comparing to 2x expensive models. My friend thought they were 6.5s until I pulled the covers off, crazy loud for the size.

Incredibly punchy for their size, quality product build and sound. They look great too. I’ve never not been impressed by a massive audio product, and here I am, happy again!!

Put on Harley faring. Highs are sadly poor mids are fair. Decent price nice packing speakers were boxed in. Yes that's important first impression but polls or infinity kappa are far better choice.

I highly recommend the FX series Replaced my factory 5.25" Bose speakers with these, they sound better even tho factory amp is not maximizing there potential. I got a new amp to install. Just make sure you do ur home work on: RMS needed , Gain sensitivity, HPF cut off. They will sound great.

Sounds really bad and when you send them back to massive for a refund they charge you half of the speaker cost (45.00) as are sticking fee. I'll never buy massive audio again. I ended up sending everything back because of this.

They sound good but not great, rather go with kicker at the price point

Great sound quality! Massive Audio never dissapoints!

Amigos si están pensando o dudando del producto, créanme son de lo mejor yo las compré para SQ y se las puse en la parte trasera de mi Chevy swing 2005 (porque lleva de 4 pulgadas), y sonó chingón junto con mi wey FC6.3 adelante de Massive. De lo mejor.
