1. OSD Audio AP650

OSD Audio AP650

First up is a commendable pair of 6.5 inch beauties, they make for a great indoor/ outdoor two-way option, due to their all weather versatility. They are of a solid construction and come in a classic black or white finish.

The frequency response on the OSD Audio is fairly wide, ranging from 37Hz to 20KHz. The enclosure is ported for better bass response, but with the outdoor use in mind, the circuitry and internal components are completely sealed and duly protected.

The driver is impressive and the power handling goes from 10-150 watts. They are lightweight with compact dimensions and come with matching mounting brackets which swivel 180 degrees.

They are reasonably priced for weather-proofed speakers, but of course, you will already have to have an amplifier or system to hook them up to, or you will need to purchase one.

+ High end components.
+ Weatherproof.
+ Up to 150 watts of power.

Having separate types of speakers designated to different frequency ranges gives a more natural representation of sound, high-frequency sounds will often be tinny without a dedicated tweeter.

6.5 inches is an ideal dimension for car door speakers, this set makes a pretty decent upgraded replacement with their additional tweeters.

Some of the reviews in our opinion are a little unfair, Kicker makes some pretty decent, low-cost speakers and we are inclined to think that some of the disappointment found with these guys is from bass-heads, looking to deck their cars out in homage to the SPL wars.

If you aren't looking to pack your trunk with giant booming subwoofers, these are an expertly made duo.

We feel they are powerfully loud putting out a total of 240watts, with a great driven bass response for a 6.5 and that ultimately the low-end handling is determined by your set up and the mounting and enclosure methods. They come with the necessary splice connectors for simple mounting.

The components great quality and they are adept for clearer high-end frequencies. They make for an excellent car speaker upgrade and surpass most expectations given their appealing price-tag.

6.5” Speaker Buyers Guide

What to look for in 6.5 speakers?

What you need to look for is entirely down to the kind of speaker you require on the surface they are the same dimension and function in identical manners but some will be actively powered and therefore a standalone product, others will be used as an addition to a speaker amplifier.

We have reviewed a cross-section of different types of audio solutions based on your FAQs around the 6.5-inch speaker realm. If you were looking for budget bookshelf speakers or monitors with speakers enclosed with the given dimensions, relax as we have a selection of speaker-related articles packed with reviews and each with an informative buyers guide for your benefit.

Once you know what type of speaker you are looking for fit for its purpose, you want to think about whether you require any specific features, for example weatherproofing for outdoor use.

Speakers are constructed with a cone and an electromagnetic coil which creates a magnetic field when a current is introduced. This field attracts and repels the electromagnet away from a firmly fixed permanent magnet which has a piston effect on the cone dispersing the air around it and creating audio waves. Higher sounds have higher frequency waves meaning that when a speaker plays a high pitch it is moved in and out extremely rapidly, this can create a lot of heat.

Different types of materials for cones are better for certain frequencies, for example, silk or paper or silicone is very good for high-frequency sound, heavier bass requires something denser that still reverberates. The materials can differ greatly and can be of a composite nature, some high-end speakers even use cutting-edge Kevlar designs.

If you want a full range sound you will need a driver set up with at least 2-way class speakers, one to cover the upper end and one for the lower registers.

You will find the depth and overall sound is even better if you have a typical loudspeaker set-up with a woofer, speaker and tweeter classified as 3-way. Having something dedicated for different ends means that the components used in the driver can be made from materials better suited. A designated tweeter, for example, will have design aspects specifically calibrated to cope with high temperatures that come as a result of excessive kinetic energy with nowhere to go.

Another thing to consider is power consumption and what wattage you are looking for.

Best budget 6.5 speakers?

The contender that clearly gets the crown for the best budget 6.5-inch speaker is the BOSS Audio set, they're our lowest priced pair and they are a 3-way class, providing well balanced, diverse spectrum audio. They feature some premium optimizations and come from a trusted brand.

Most durable 6.5 speakers?

For most durable we would suggest the Infinity Kappa pair, they are considerably well manufactured and their patented Plus one cone technology means they handle and perform exceptionally well. If their price tag is out of your reach the most durable cheap option would be the Kenwood set they are 3-way through the bass is a little subtler than you might desire.

Best overall 6.5 car speaker?

Again we go for the Boss Audio pair the sound is unbeatable without paying at least double the price and even at that level of the market we don't typically see 3-way models that can handle the same wattage as these babies can manage.

Best sounding 6.5 speakers?

We think the Pioneer pair have the best sound overall, they are a fantastic full range 3-way class set and they handle 320 watts. Their multi-layer Mica Matrix cone is hypersensitive and super responsive. The series has had many refinements and incorporated features from their higher end lines in the affordably priced set. The fidelity is noticeably different and we like the new cosmetics also.

Conclusion

The set of speakers you decide to go with is tied to the function you require of them. In our buyers guide we have attempted to sort each categorically as to what they are best for. Hopefully, this along with the lashings of info will aid you in your search for a suitable 6.5-inch speaker for you.

Be honest about what you really need from your speakers, many people overbuy in terms of power and many people crave a subwoofer on a sound system which they will probably, in reality, will rarely use.

If you are shopping on a lower budget is always a good idea to go with a reputable brand to get a valuable bargain instead of a cheap knock-off.

The key factors desirable in a decent set of car speakers are a 3-way class set up to cover a better frequency response, low impedance a mount size that won't be impeded in your vehicle, sensible wattage and cooling methods implemented in the design.
