Choose the PRO-ZT69 if you want a coaxial arrangement with both driver types in one speaker and your vehicle accepts its 6x9-inch dimensions. It has a 4-ohm rating and a specified 275-watt RMS handling figure.
The DS18 packages here instead provide separate midrange speakers and tweeters, which may suit a different system layout. Confirm the opening, depth, amplifier match and whether you need one speaker or a pair before ordering.
6.5-Inch Midrange and Tweeter Set
DS18 Mid and High Car Speaker Package - 2X 6.5" Midrange, 2X 1" Tweeters, Built-in Crossover
This DS18 package pairs two 6.5-inch PRO-X6.4BM midrange drivers with two 1-inch PRO-TW220 tweeters. It is a component-style set rather than a coaxial speaker with a tweeter mounted in the same unit.
The midrange drivers are rated at 250 watts RMS and 500 watts maximum at 4 ohms; the tweeters are rated at 225 watts RMS and 350 watts maximum at 4 ohms, with a built-in capacitor filter. That makes it a candidate for a system planned around separate drivers.
Check each mounting location and the intended crossover and amplifier setup before buying.
Best For: Builds that need a pair of 6.5-inch midrange speakers plus separate tweeters.

Choose this set when you want 6.5-inch midrange drivers and separate tweeters as a coordinated package. It supplies two of each, unlike the single-speaker PRO-ZT69.
Its midrange rating is 4 ohms, and the tweeter’s separate power rating and capacitor filter should be considered when matching the rest of the system. Check that the vehicle can accommodate both driver sizes and that your installation plan supports separate mounting.
Pair of Bullet 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 includes two 6.5-inch midrange loudspeakers, each with a red aluminum bullet dust cover. Each driver is rated at 250 watts RMS and 500 watts maximum at 4 ohms.
The 1.5-inch high-temperature CCAW voice coil is another specified component detail. This is not a coaxial model with a tweeter integrated into each speaker, nor does the package include the separate tweeters found in DS18’s mid-and-high sets.
Consider it when you specifically need a pair of midrange drivers and have a plan for the rest of the system. Verify mounting fit and amplifier compatibility.
Best For: Systems that need two 6.5-inch midrange drivers without an included tweeter pair.
| Pros | Cons |

This pair fits buyers who already have a system plan for dedicated 6.5-inch midrange drivers. Compared with the 6.5-inch DS18 mid-and-high package, it does not bundle tweeters, so account for any additional components your setup needs.
The drivers are rated at 4 ohms and 250 watts RMS each. Check the vehicle’s mounting dimensions and the amplifier’s compatibility before choosing them for a coaxial-speaker replacement.
8-Inch Midrange and Tweeter Package
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
This DS18 package contains two 8-inch PRO-GM8 midrange drivers and two PRO-TW120 super tweeters. The midrange speakers are rated at 190 watts RMS and 580 watts maximum at 8 ohms, while the tweeters are rated at 200 watts RMS and 300 watts maximum at 4 ohms.
Their different impedance and power figures call for checking each driver against the intended system configuration. This is a separate-driver package, not a conventional coaxial speaker with an integrated tweeter.
Its 8-inch midrange size also makes fit a key consideration: verify the available mounting space and installation layout before buying.
Best For: Installations planned for two 8-inch midrange drivers and separate tweeters.
| Pros | Cons |
|---|---|
|
|
Consider this package if your planned installation has room for two 8-inch midrange drivers and separate tweeters. It differs from the 6.5-inch DS18 set in both driver size and the midrange’s 8-ohm rating.
The PRO-TW120 tweeters have a separate 4-ohm rating, so check how each will connect to the rest of your system. Measure the openings and confirm the amplifier setup before choosing it for a coaxial-speaker project.
8-Inch Midrange and High-Frequency Set
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
The DS18 PRO-X8.4BMPK package combines two 8-inch PRO-X8.4BM midrange drivers with two 1-inch PRO-TW220 tweeters. The midrange drivers are rated at 275 watts RMS and 550 watts maximum at 4 ohms.
The tweeters are rated at 225 watts RMS and 350 watts maximum at 4 ohms, with a built-in capacitor filter. This package is designed around separate midrange and high-frequency drivers, so it does not provide the single-unit coaxial layout of the PRO-ZT69.
Check the vehicle’s room for 8-inch drivers, the separate tweeter positions and the amplifier match before buying.
Best For: Installations that call for two 8-inch midrange drivers with separate PRO-TW220 tweeters.
| Pros | Cons |
|---|---|
|
|
Choose this package if your system plan calls for 8-inch midrange drivers and separate tweeters, with both rated at 4 ohms. It offers a different setup from the PRO-GM8 package, whose midrange drivers are rated at 8 ohms and whose tweeters are a separate model.
Compare those electrical specifications with your amplifier and wiring plan. Also measure the midrange and tweeter mounting locations; an 8-inch driver may not fit a factory opening intended for a smaller coaxial speaker.
How to Choose Coaxial Car Speakers
How We Picked Best Coaxial Car Speakers
The candidates include one clearly identified two-way coaxial model and four DS18 packages built around separate midrange and tweeter drivers. The PRO-ZT69 is the direct match for shoppers seeking a tweeter integrated with the midrange in a single 6x9-inch unit.
The other options are useful for comparing component-style upgrades, but require an installation plan for separate drivers.
We focused on the configuration, included quantity, speaker size, impedance and power ratings that are provided for each product. Those details help distinguish a compact 6.5-inch package from an 8-inch setup, or a single coaxial speaker from a pair of midrange speakers with tweeters.
Each candidate is included because it is relevant to car audio speaker upgrades, while the key difference in design is made explicit.
Comparing Coaxial Car Speakers and Component Sets
For a conventional coaxial setup, the PRO-ZT69 combines the midrange and bullet tweeter in one speaker. It is a 6x9-inch, 4-ohm unit rated at 275 watts RMS.
It is sold as one speaker, so check the quantity needed for your vehicle.
The DS18 packages use separate drivers. The 6.5-inch PRO-X6BM pair contains midrange speakers only; the 6.5-inch package adds two PRO-TW220 tweeters.
The two 8-inch packages also include separate tweeters, but their ratings differ: the PRO-GM8 midrange is 8 ohms, while the PRO-X8.4BM midrange is 4 ohms. The tweeter models and power ratings also differ, so compare the complete system requirements rather than relying on a single maximum-watt figure.

Check Speaker Size and Installation Space
Size labels alone do not confirm vehicle fit. For the PRO-ZT69, the specified front cutout is 8.62 by 5.91 inches and its mounting depth is 3.35 inches.
For the other products, the supplied details identify 6.5-inch or 8-inch drivers but do not give mounting depths. Measure the existing openings and available depth, and confirm the separate tweeters have suitable mounting locations where applicable.
The PRO-ZT69 is the only candidate here with supplied cutout and depth dimensions. If those measurements do not suit your car, confirm the required fit details for the intended alternative before buying.
Also check whether you need an adapter or other installation parts; they are not specified for these products.
Match Power Ratings and Impedance to Your System
Use RMS ratings and impedance when comparing speaker options with an amplifier. The 6.5-inch DS18 midrange drivers are rated at 250 watts RMS and 4 ohms.
The PRO-X8.4BM midrange is rated at 275 watts RMS and 4 ohms; the PRO-GM8 is rated at 190 watts RMS and 8 ohms. Their bundled tweeters have their own ratings and impedance, which also matter to the system layout.
Maximum power figures are not the same as RMS ratings. Check the amplifier’s supported impedance and output, and consider each driver’s specified rating.
For separate-driver sets, confirm how the midrange speakers and tweeters will be connected and filtered; the PRO-TW220 tweeters have a built-in capacitor filter.
Choosing a Car Speaker Setup for Your Build
Choose the PRO-ZT69 if you want an integrated 6x9 coaxial speaker and its dimensions fit. Pick a 6.5-inch midrange-and-tweeter package if that size suits your installation and you want both driver types included.
The PRO-X6BM pair makes sense when you need midrange drivers alone and already have a plan for high-frequency drivers.
For larger installations, compare the two 8-inch sets by their electrical ratings and tweeter model. The PRO-X8.4BMPK has 4-ohm midrange drivers and PRO-TW220 tweeters; the PRO-GM8 package has 8-ohm midrange drivers and PRO-TW120 tweeters.
Before ordering any option, confirm the number of speakers included, mounting fit and system compatibility.
