## Overview

The EARTHQUAKE Sound SLAPS-M12v2 is a patented, user-tunable 12-inch passive bass radiator designed to boost subwoofer output by up to +6dB without extra amplifier power or enclosure size. Its slim profile (<3 inches) and symmetrical suspension design enable deep, distortion-free bass in compact enclosures, making it ideal for both home theater and mobile audio enthusiasts seeking powerful, customizable low-frequency performance.

## Description

The Earthquake Sound SLAPS-M12v2 is a tunable passive bass radiator that significantly increases subwoofer efficiency and ability for ultra-low frequency reproduction without additional amplifier power or enclosure volume. Designed to perfectly complement all good quality long throw woofers on the market, SLAPS add up to +6dB of bass compared to regular sealed and ported enclosures. The benefit of SLAPS being user-tunable is that they can be integrated into virtually any subwoofer/enclosure combination. SLAPS (Symmetrically Loaded Audio Passive System) overcomes the limitations known from the conventional sealed and ported enclosures that tend to limit excursion. As the name indicates, SLAPS is built symmetrically, distinguishing it from traditional or other inferior passive devices on the market today. SLAPS technology integrates a dual structure of identical opposites in its suspension design, resulting in identical properties in both the negative and positive pressure domain. The high efficiency and performance are a result of the pneumatic coupling between SLAPS and an active driver. The unique and patented design of SLAPS allows the active driver compression-free excursion, resulting in a deep, dynamic, and powerful bass response.

Review: I ran this for a couple of years in a diy home theater sub and not knowing what I was doing had way too much weight on it trying to get it to dig low. It made my sub bottom out and I had to turn it way down. About a year ago I decided to try it in the trunk of my car with a different subwoofer and played around with the weight. I ended up removing the pre installed weight and took it down to about 200 grams total and in my 1.2³ft box, that was exactly what I was looking for. With my single skar svr12 on 1.5k this thing dug down to ~ 25hz before dropping off noticably. I probably still had too much weight as it started ripping the inner surrounds and ripping apart the passive radiator. I don't know if it impacted something in the trunk or the weight over time cracked the cone. Anyways it ended up destroying itself but I'm so impressed with the sound that I ordered another. I got 3-4 years out of that one so it didn't owe me anything. I'll attach a video of it beating and the aftermath, but if you're more sensible than me and willing to actually take the time to tune it instead of just throw weight at it and go you'll get even longer use out of it without with of destroying things. I never thought I could get a single cheap 12 to seriously flex my windows at 26hz but this little beast made it happen. Even though I killed it I obviously still recommend it, it's expensive for a pr but definitely worth it! Now to get this new one broken in :D
Review: Best quality passive radiators built 3 of my own subs using earthquake passive radiators. The bass is so deep and power full. I'm modifying my 2 Klipsch 12 inch subs to passive radiators subs.hopefully the Klipsch will have as much bass as my home made subs.
