Top 10 Best 8 Inch Car Subwoofers Reviews In 2024

Features :

• Cone – Made from Polypropylene, The CXX8 8 Inch Car Subwoofer Provides a Resilient and Durable Material That Can Offer Great Sound with The Advantage of a Long-Lasting Subwoofer
• Surround – Rubber has the ability to endure much punishment without any sign of damage. It complements the whole structure of the speaker by allowing constant abuse where it is most needed, without the wear and tear
• Stamped Basket – A stamped basket can absorb and transfer much of the energy produced by the speaker. It has good corrosion resistance, good mechanical property, high thermal and electrical conductivity and retains strength at high temperatures.
• Voice Coil – Our voice coils are able to withstand high temperatures yet maintain its strength and fatigue properties. Making our voice coils with this material gives our speakers the advantage of longer pay times with lower weights
• Specs – Resonant Frequency: 49 Hz, Sensitivity SPL (1W/1m): 83 Db, Dimensions: 8. 25” x 8. 25” x 4. 3”

Features :

• Built-in Amplifier – Low-Profile Subwoofers that are amplified do not need an external source and are generally very compact
• Mosfet Power Supply – With a MOSFET power supply you get improved switching speeds, better performance with less power from the driver, lower gate-to-drain feedback capacitance, lower thermal impedance for higher switching frequencies
• Variable Low-Pass Filter – A low-pass filter is an electronic circuit that removes all the notes below the filter’s frequency setting. You will use the Low-pass filter to primarily keep high notes out of your subwoofer(s)
• High & Low Level Inputs – A low level (RCA) input is measured in voltages. A high level (+/- wire) input is measured in wattages. Both essentially carry signal from your receiver to your amplifier to your speakers
• Variable Bass Boost – Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it
• Variable Gain Control – The gain control is not for adjusting volume. It simply adjusts the amount of signal that is coming from your receiver and going to your amplifier
• Phase Control – Phase control lets you adjust the speaker phase with the amplifier depending on the location of the subwoofer. This will avoid possible sound cancellation depending on the setup
• Specs – 12.2” x 8.9” x 3”, 8.8 lbs.

Features :

• Cone – Made from polyurethane, the CG8D 8-inch car subwoofer provides a resilient and durable material that can offer great sound with the advantage of long-lasting subwoofers
• Voice Coil – Dual voice coils will not produce more bass than a single voice coils. It is more about producing the right Ohm load for maximum efficiency from the amplifier that you are running. Ohms are a measurement of electrical resistance
• Surround – Foam is very flexible, providing the subwoofer with higher efficiency. This also translates to better excursion. (How far the cone of a speaker linearly travels from its resting position)
