i had similar model of those bass shakers a while back. 1B's i think they were. (basically a low profile version of the 2B's without the fins) . they are tough as nails. had 4 of them in my fiero seats since there is ZERO room for actual subs. they creak and crunch and pop a bit while they break in (have a weight suspended in a fiberglass (actually kevlar) suspension.) don't worry, once they have broken in they will be good. you just have to get all the weak fibers in the suspension broken down. as far as the amp goes... it's 70 watts and 2 channels. that's more like 45w RMS x2 channels. not likely to blow up anything. I find stupid people blow stuff up more with improper loads. Believe me, I did installations for 10 years professionally. Ive seen it all. this amp will probably do just fine. it's not the most powerful, but it'll do. rule #1 when setting up subs... 1) turn down your amp driving your subs 2) turn up the rest of your system as loud as you would ever like it 3) turn up your subs just till they start to distort and then back them off a bit. 4) leave the level the hell alone. if the bass sounds low after this adjustment, it's because it's SUPPOSED to be like that. while i realize the term "distort" is subjective, you can tell the difference between a nice clean bass tone and one that is starting to distort. This is where test tones will come in handy. You can download apps for your phone and reproduce any frequency you like. pick a 40hz tone and start turning it up...you'll notice when it changes from a nice clean sine wave and stats clipping. the sound very quickly changes. |

I have a set of the basic model, which I think is like half the power. I used the tiny amps that came with them. I think each shaker I have is rated to 15 watts. You wouldnt think that was enough to move squat... however... I installed both under a swivel chair as a test. Fired up some classic mame games... like Gyruss. Fire one shot in that game, and wait... cause as that shot goes deep into the screen... the bass gets insane. I turned up the little aura amps to max. There was so much vibration, that I couldnt play a game, because it looked like someone was shaking my monitor. Totally blurry. Those little boogers are powerful, when mounted to the proper places. You would probably know if these were getting too much power, because they would probably bottom out.. and make some odd noises in the process. Though, being that you have the pro model, I seriously dont thing your gona have that issue. Remember, this isnt really a subwoofer. Theres no airflow, mostly just vibrations. Mount them on a framework thats solid and closest to where you want to feel them thump. Any kind of cushion or spring is going to absorb a lot of the vibrations. Custom built internal frames are probably going to give you the best bang for your buck. You do want to limit the highs & maybe the upper mids too, with a crossover, to avoid too much power wasted on a spectrum that you dont want or need. Even then, there may be some audible sound that comes from them. Which you really wont hear when its mounted under a seat... with game volume at a mild level. You might also want to put vibration dampeners on your cabs feet.. because the vibrations will probably be felt around the house (shaking things off shelves if up high enough) , or if in an apartment.. the neighbors will come to pay you a visit. Many Subwoofers that people use for their Pc's are low power, and dont push a lot of air. Hence, neighbors may not even hear.. especially at medium levels of volume. But Bass Shakers are very similar to a full power car sub... where the trunk rattles from the vibrations, without the air-pressure... and with only a few watts of power. Whats cool about Bass Shakers, is that you actually feel more from them than a typical sub. You will feel things from Footsteps, to doors closing. Not just explosions. Finally, Bass Shakers provide the Bump.. but, they are not really for taking care of woofer sounds. So, make sure you have a decent set of speakers as well. A lot of modern speakers are cheaply made, with poor audio representation (especially the overpriced PC speakers) ... and they use tiny satellites with "limited-range" speakers, with all the deeper bass being played by the sub. The sub usually not being a true sub, or, if it is... your going to miss out on a good deal of typical woofer frequencies that a Sub does not typically utilize. Of course, this is really subjective to your taste, the quality of your hearing, and what kinds of games / music you will be playing. Ohh, and also, if your using on-board (built in) audio, instead of a sound card... you might as well not even bother with decent speakers. Every Motherboard Ive heard with onboard audio, is absolute garbage. Very limited spectrum, lot of distortion, and their EQ doesnt really help much to fix it. My old Soundblaster Audigy stomps all over the latest multichannel onboard crap, by Miles. (as well bests the top mp3 players, playing loss-less audio) |

Those bass shakers are awesome. I have 4 installed in my couch and they augment any movie featuring explosions. It feels like bombs are going off. I also have 2 installed in my driving seat. Anytime I drive over rumble strips or curbs you can feel it. I recommend them highly, but be sure to add an easily accessible switch in case you want to turn it off. The effect is not for everyone. An added benefit is since they are felt and not heard, your not going to be upsetting any wife or neighbor. I use a 500 watt amp, but that is definitely overkill. I probably have the volume @ 15-20 percent. Any more and its too much and out of balance detracts from the audio. |

Thanks for the replies. I wasn't expecting the experience described by Xiaou2. My cabinet is composed of separate pieces. The seat section is its own component, a sheet of MDF on six casters with a platform of 2*4s on which sits a car seat. (I have yet to bolt the car seat to the platform. Sounds like I'll need to do that now) I have a monitor stand (MDF sides and shelf) that fits snugly over the front end of the seat section. It sounds like I'll be fine (as far as feeling the shaker) with mounting the shaker on the base MDF sheet. This is on carpet (in a basement), so hopefully I'm not in danger of rolling away from, or toward to, the monitor stand. Currently I have the PC just on the floor next to the cab. Even though it's not touching the cabinet, maybe I should put it on a pillow or something. I don't have sub-out on my receiver, so it looks like I will have to use the speaker-level inputs on the amp. Is there anything to watch out for when using these? |
