Pick this package if you want a matched four-driver set and have places to install separate 6.5-inch midrange units and 1-inch tweeters. It offers more installation components than a single coaxial speaker, so it is a less direct replacement when your goal is one driver per factory opening.
Compare your amplifier's output with the separate ratings, and verify the mounting and crossover arrangement for your vehicle.
8-Inch Package for 8-Ohm Systems
DS18 PRO-GM8.4PK Mid and High Complete Package - Includes 2X Midrange Loudspeaker 8" and 2X Aluminum Super Bullet Tweeter 1" Built in Crossover - Door Speakers for Car or Truck Stereo Sound System
The DS18 PRO-GM8.4PK package combines two 8-inch midrange speakers with two 1-inch aluminum super bullet tweeters and a built-in crossover. Its midrange drivers are rated at 190 watts RMS and 580 watts maximum at 8 ohms.
The included PRO-TW120 tweeters have ferrite magnets, a built-in capacitor filter, and ratings of 200 watts RMS and 300 watts maximum at 4 ohms. This is a separate-driver package, not a one-piece coaxial speaker.
Its larger midrange size and differing impedances make installation planning especially important; check available openings and how the drivers will connect to your system.
Best For: Installers seeking paired 8-inch midrange drivers and separate tweeters for an 8-ohm system.
| Pros | Cons |
|---|---|
|
|
Consider this set when your installation can accommodate 8-inch midrange drivers and you want separate tweeters as part of the upgrade. Its 8-ohm midrange rating distinguishes it from the 4-ohm 6.5-inch package, while the tweeters have their own 4-ohm rating.
Confirm fit and the intended wiring before purchase; this package is not a straightforward coaxial replacement for a single factory speaker location.
8-Inch High-Power Package
DS18 PRO-X8.4BMPK Mid and High Complete Package - Includes 2X Midrange Loudspeaker 8" and 2X Aluminum Super Bullet Tweeter 1" Built in Crossover - Door Speakers for Car or Truck Stereo Sound System
This DS18 package includes two 8-inch midrange loudspeakers and two 1-inch aluminum super bullet tweeters with built-in crossover components. The PRO-X8.4BM midrange drivers are rated for 275 watts RMS and 550 watts maximum at 4 ohms.
The PRO-TW220 ferrite tweeters have a built-in capacitor filter and ratings of 225 watts RMS and 350 watts maximum at 4 ohms. Together, the four drivers offer a separate midrange-and-treble arrangement rather than a single coaxial unit.
The 8-inch size calls for a careful fit check, and you should verify the crossover connections and amplifier match before installation.
Best For: A paired 8-inch midrange-and-tweeter upgrade for buyers checking 4-ohm system compatibility.
| Pros | Cons |
|---|---|
|
|
Choose this package if you want two 8-inch midrange drivers and separate tweeters, and your system is compatible with their 4-ohm ratings. Its midrange RMS rating is higher than the PRO-GM8 package's stated figure, while both use 8-inch drivers.
Fit remains the central tradeoff: check the door or custom mounting location before choosing either 8-inch set. Also plan for the included crossover components.
Pair of Bullet-Cover Midrange Drivers
DS18 PRO-X6BM Loudspeaker - 6.5", Midrange, Red Aluminum Bullet, 500W Max, 250W RMS, 8 Ohms - Premium Quality Audio Door Speakers for Car or Truck Stereo Sound System - 2 Speakers
The DS18 PRO-X6BM package contains two 6.5-inch midrange speakers with red aluminum bullet dust covers. Each driver is rated at 250 watts RMS and 500 watts maximum at 4 ohms in the product details.
The design also uses a 1.5-inch high-temperature CCAW voice coil. These are midrange drivers rather than coaxial speakers with an integrated tweeter, so they suit a different kind of system upgrade.
Consider them when your car audio setup already has a separate plan for high-frequency output. Verify the mounting fit and confirm the amplifier and crossover arrangement before purchasing.
Best For: A pair of 6.5-inch midrange drivers for systems already handling high frequencies separately.
| Pros | Cons |
|---|---|
|
|
This pair can fit a system upgrade when you specifically need 6.5-inch midrange drivers and already have high-frequency output covered elsewhere. It is not the most direct match for a search focused on coaxial speakers, because the tweeter is not integrated.
Compare the 4-ohm rating and power figures with your amplifier, and confirm the car's mounting depth and crossover plan before buying.
How to Choose Coaxial Car Speakers
How We Picked Coaxial Car Speakers
The most relevant candidates include a true coaxial speaker alongside separate midrange-and-tweeter packages that may appeal to shoppers planning a larger car audio upgrade. We prioritized clear driver configuration, speaker size, impedance, power ratings, and included components.
The PRO-ZT69 is the direct coaxial option because it combines a midrange driver and tweeter in one 6×9-inch unit. The other choices are multi-driver sets, so they belong in the comparison only for buyers considering a component-style installation.
Package contents matter as much as headline power figures. A single speaker, a pair of midrange drivers, and a four-driver set call for different purchase plans.
We also considered whether the available details help buyers check fit, amplifier match, and system connections before ordering.
Comparing Coaxial Car Speakers and Multi-Driver Packages
For a straightforward coaxial car speaker replacement, the PRO-ZT69 is the clear format match: it combines two driver types in one 6×9-inch speaker and includes a grill. Remember that it is sold as one speaker.
The DS18 packages instead include separate midrange drivers and tweeters, with either 6.5-inch or 8-inch midrange sizes.
The 6.5-inch DS18 package has 4-ohm midrange drivers and separate PRO-TW220 tweeters. The two 8-inch packages offer different midrange ratings and configurations: the PRO-X8 set is rated at 4 ohms, while the PRO-GM8 midrange drivers are rated at 8 ohms and its tweeters at 4 ohms.
The PRO-X6BM is a pair of midrange drivers without integrated tweeters, so it fits best when high-frequency components are already part of the system.

Check Speaker Fit and Amplifier Match
Start with the existing speaker opening and the available mounting depth. A 6×9 coaxial speaker, a 6.5-inch midrange driver, and an 8-inch midrange driver cannot be assumed to share the same fit.
For a coaxial car speaker replacement, check the vehicle's opening and mounting arrangement before ordering. For a multi-driver system, also plan locations for the separate tweeters and allow for the supplied crossover components.
Next, compare the nominal impedance and RMS power rating with your amplifier and the rest of the audio system. Maximum power figures provide another point of comparison, but the RMS ratings and impedance are the practical details to check together.
Some packages specify separate ratings for midrange drivers and tweeters, so do not treat them as one combined power figure.
Which Coaxial Speaker Setup Fits Your Car?
Choose the PRO-ZT69 if you want one 6×9 speaker with a built-in tweeter. Choose the 6.5-inch DS18 package if you want paired midrange drivers and separate super tweeters in a smaller format.
The two 8-inch packages suit buyers who have room for larger drivers and are prepared to plan a separate-driver installation.
The PRO-X6BM pair is the niche choice for adding midrange output where high frequencies are handled separately. Before buying any option, verify how many speakers are included, the mounting dimensions your vehicle accepts, and whether the amplifier and crossover setup match the drivers.
