5 Best 6.5 Component Speakers (Updated Dec. 2018)

We’ve had a ton of requests to start including component car speakers in our reviews. We have done a few. However, we feel we have left out some of the best 6.5 car speakers and brands, and well, we would like to redeem that.

Component speakers (also referred to as “separates”) feature separate woofers, tweeters, and crossovers. They offer better overall sound quality than coaxial speakers, making them the choice of serious audio enthusiasts who cares about nothing but high sound quality.

Shopping for 6.5 component car speakers is a pretty daunting task. The sheer number of speakers available online or in car audio stores is enough to make your mind spin.

Most people have a general idea of how their speakers should sound, but are often intimidated by the choices available. We narrow down those choices with 5 top-rated 6.5 component speakers.

2. Rockford Fosgate P165SI Review

Rockford Fosgate P165-S 6.5 component speakers reviewRockford Fosgate is one of the oldest and most trusted names in the car audio industry! They were established in 1973.

They offer a wide collection of speakers, subwoofers and amplifier for cars, boats, as well as for recreational vehicles and home use.

With their reasonably-priced quality audio components, Rockford Fosgate enjoyed great success all over the world.

We’ve got the chance to mount several Rockford Fosgate subwoofers, amps and speakers, and boy they’re huge difference makers.

The P165SI are the best performing 6.5 component speakers in Rockford Fosgate “Punch” series. They feature responsive polypropylene made woofer cones enhanced by rubber surround that’ll stand up to hours of high-volume jam.

These speakers comes with separate 1″ dome tweeters engineered to provide clear, sharp highs that will cut through big bass and road noise.

The Rockford Fosgate P165SI speakers can handle a decent amount of power on continuous basis – up to 60 watts – they’re rated for a sensitivity rating of 90 dB.

The only downside we can reasonably think of is their relatively narrow frequency range. While many 6.5 component speakers we included here can reach as low as 30 Hz, the P165SI speakers are stuck at only 60 Hz. This can negatively impact the bass fullness.

  • Sensitivity : 90 dB
  • Power Handling 
    • Peak  :  120 watts
    • RMS  :   60 watts

3. Infinity Reference 6500CX Review

Infinity Reference 6500CX component speakers reviewInfinity Systems is an American manufacturer of loudspeakers founded in 1968. They’re one of the speaker brands under the umbrella of Harman International – a US-based high-end audio company – since 1983.

They produce packages for a range of audio applications, including multi-channel surround sound systems packages, in-wall home speakers, marine applications, as well as car audio applications.

The speakers reviewed here, the Reference 6500CX, are the best performing component speakers that Infinity has to offer.

These speakers use 3/4″ edge-driven textile dome tweeters that are engineered to yield a amazing levels of detail without sounding harsh. These tweeters can be either surface- or flash-mounted using the included mounting cups.

The Reference 6500CX speakers can handle 90 watts on continuous basis. They’re very responsive, featuring a high sensitivity rating of 93 dB which makes them suitable for systems running off both headunits and external amplifiers.

If I had to pick some criticisms for these speakers, I’d have to say that their frequency range of 53 – 21 kHz is relatively narrow compared to the other speakers in the same category, which can cover low frequencies down to as low as 30 Hz and high frequencies of up to 23 kHz. This makes the speakers leave a lot to be desired, particularly in terms of bass.

  • Size : 6.5
  • Sensitivity : 93 dB
  • Power Handling 
    • Peak  :  270 watts
    • RMS  :   90 watts

Why component speakers sound much better?

They separate woofers and tweeters

Full-range speakers consist of a woofer for the lows, and a tweeter mounted onto the woofer to produce the highs, all combined in one speaker. Combining all the drivers in one unit is a convenient way to get great sound in a single opening.

The downside, however, is that the the woofer and tweeter are both compromised to some extent in this arrangement. Additionally, a tweeter mounted on top of the woofer cone will always, at least to some degree, interfere with the sound waves produced by the woofer.

A typical component system consists of separate woofers, tweeters, and external crossovers — all of which come designed to work in conjunction with one another.

In component speakers, the woofers and tweeters are mounted separately from each other, so that each component can operate to its full potential, eliminating the problem of the tweeter impeding woofer performance. This also allows you to mount and position the tweeters for optimum imaging and sound-staging.

They use external crossovers

Component speakers use external crossovers to route sound frequencies to the correct driver – lows to the woofers and highs to the tweeters – so that each component gets only the range of frequencies it’s designed to play. Thereby, you’ll enjoy distortion-free, more efficient sound reproduction.

They can handle more power

Component speakers are often built with high quality materials and can handle a great deal of power than their same-brand coaxial counterparts.

They’ll sound great running off of your aftermarket headunit, but they’ll really shine when powered by an external amplifier. The trick here is to avoid under-powering your speakers. If you want your component speakers to really sing, feed them enough power.

In case you don’t intend to add an external amp to your car audio system, then make sure you get a pair of component speakers that can perform well on just the headunit.
