DROK 4 Inches 4 Ohm Audio Speakers for Cars - 40W Anti-Magnetic Car Stereo Speakers with 87dB High Sensitivity, Thumping Bass, and Loudspeaker Subwoofer - Ideal for 2.0/2.1 Home Stereo, DIY Boombox, and Satellites Review

Bought these to replace some of the speakers in my old Peachtree M24 kit. Bass quality wasn't great, but that's to be expected when moving from $200 speakers to these. But I will say for the money this is stealing! Definitely recommend

This is a really cool 4" woofer! Used in a well tuned vented cabinet it's actually very low with decent output! Up to 40z with no issues, keep an eye on input power !I can't remember the exact size of the box but it was about 0.35 cu.ft with a 1.5" x 8" port. Woofer tester and BassBox is your friend!

I use 2 of these behind my seat in my S10 pickup. I run it from my old school Kenwood KDCMP828. I made custom boxes. Wow, these little guys put out some good bass. I even feel a tingling in my back. I've been using them for a little over a month and they're still rattling! It's not a 12 inch sub, but for $30 I have one hell of a stereo! Thank you for selling a quality product. I will definitely buy again.

I bought a 4" subwoofer for my moped to try and add bass to a system with no bass. It sounded awful, so I returned it and decided to put my own together.I went with this little D-Rok subwoofer which had good reviews and had a big magnet on it.I have a Nippon HC-101 (120Hz) crossover and an Aoshike Added 8-25V Class D amplifier I designed and 3D printed my own box with holes to fit perfectly in the storage compartment under my moped seat It took some adjustments to the punch level in the box to…
