One thing I have been toying around with, is the idea of how these are mounted. I know that they have to be mounted as solidly as possible otherwise they will rattle blah blah blah... but I think I might have found the reason why my aura pros are shaking my whole couch with ease. I have the aura pro mounted to a cross beam inside the couch, not near where supports intersect or attach to each other, but smack dab in the middle of one of the longest cross beams which is about 3 feet long, so where the bass shaker is mounted on that beam it is about 1.5 feet from where that beam attaches to other pieces of wood. So when the bass shaker transfers its energy to the beam it is mounted to the beam its self has a chance to shake sympathetically along with the bass shaker and effectively transfer the energy to the rest of the couch. If the bass shaker was mounted to a more rigid area then it is less likely to shake with the shaker but instead resist the shaker. Simple little experiment that you can do to mimmic this idea if you have stairs with a railing. If the railing has a long enough stretches between mounts you can try this. Hit the railing hard with your fist where it mounts to a support, notice how it sounds and vibrates. Then move to a spot in the raling that is exactly half way between supports, hit the railing with the same force with your fist, notice how much more the railing vibrates and how much more loudly it sounds. So by mounting bass shakers to parts of the frame of seating that are furthest from joints you can more effectively transfer energy and get more shake out of your shakers. Now how this transfers to how accurate and tight the bass feels I am not sure, this would take more experimenting.

I have heard great things about the Clark Synthesis, I might have gone with these had I not already had the aura pro bass shakers. For now I am perfectly content with the aura pros, maybe once I have about $200 burning a hole in my pocket I will purchase a couple and try them out.

You can wire the three shakers in series and show the amplifier a 12 ohm load.

The apa150 goes deeper than 50 hertz, you're looking at lowest setting on the variable low pass filter which would be perfect for bass shakers. How many shakers are you needing to power? The apa150 should be able to easily power 4

Well the answer seems to be resounding! I will keep the Marantz amps! Thank you to everyone that gave me their two cents, I am always seeking to learn more than just the do's and don'ts but more about the "Why's"

I'm aware that the EP2500 is the older model, which is why they are available used for under $200 in some cases. Is there a reason why the behringer shouldn't produce good sound quality?

I'm always trying to get the best bang for my buck in this home theater hobby. I currently have two Marantz MA-700 amps powering my Klipsch KLF-30's. I am wondering if I could expect similar sound quality if I sold my two Marantz MA-700 mono blocks and bought a Behringer 2500 two power the KLF-30's. I would be able to pocket some cash, gain some headroom, and gain the long term durability of a pro audio amp that would never be pushed anywhere near its limits. Is this idea blasphemy? I could end up with about $250 in my pocket by doing this switch.[:^)]

I would also like to know about where to get these.

Pl premium is a much better suited adhesive for this type of project than liquid nails. I didn't even have to remove the old adhesive, works like a charm. Just my two cents.

After you throw in the EQ as a factor then yes you can have more authority at the shakers low frequency capabilities when you boost at the lower capable frequencies of the shaker without bottoming it out. Just because the shakers are sitting next to each other won't make them go deeper, they will just be capable of more shake at the lower frequencies. I'm not eq'ing my shakers, but sometimes ignorance is bliss when you don't know what you're missing. So for now I am just enjoying my loose couch and loose floor and huge savings. []

So you're saying that transducers are different than speakers in that more of them will actually some how lower the frequency response that they are capable of... Not possible from what I am aware of regarding physics. I can understand the idea of being more capable of louder LFE with more transducers, but going deeper with more...please explain.[:|] I must have a couch that is perfect for bass shaking, I watched batman dark knight at reference levels and never noticed any issue with the single aura pro in my couch running out of gas. Maybe my couches are more lightweight than most [:^)]

I honestly have no idea how anyone could need more than one of these per couch, I suppose it can depend on the mounting options within the couch and how sturdy the couch is, but I still can't imagine needing more "shake" since mine can already annoy me with obnoxious shaking levels which is why I had to turn down the gain on the amp powering them. I would love to be able to mount a series of these on the floor joists of my home, but sadly my basement is finished and I would have to tear out the ceiling to do so...

That is one of my hairless cats named Meshach. Do you have others named Shadrach and Abednego? Yes I do, and another one name pyrhos

Sorry about no pics, I didn't take pics during the installation process.

Don't hesitate, just do it and you will be pleasantly surprised!

The aura pro bass shakers don't need much power at all to get shakin. Only 25-50 watts each is needed.

I looked into the buttkicker ones as well, but I was scared away from the "death rattle" problem that many of them have had. I honestly thought that I was going to have to end up using 4 Aura Pro bass shakers (2 in each couch) but I was able to get a good mount on a main support in each couch, tried out the shakers and only needed one per couch. Why I would need more "shake" than the Aura Pros, I have no idea! So I am more than happy with them, and have even had to turn them down a little bit to get them better matched with the rest of the system. I have read about people using old receivers to power them, which gives them the flexibility of turning the bass shaker volume up or down with the ease of a remote on the fly. Again, for any home theater, you'd be hard pressed to try and find a better upgrade dollar for dollar that would make this much difference in how you enjoy movies! The best way to describe it is to say that it is like going from 2D to 3D.

I have bought two different denon receivers from dakmart.com they are an authorized denon dealer that sells refurbished units. I have loved my refurbished units and never had any issues.

I was looking to push things to the next level, really make the home theater the best it could be. I had heard how some people raved about Bass shakers and how they add a whole additional dimension to the bass impact. Well a dear friend of mine was kind enough to buy me two Aura Pro Bass shakers for about $40 a piece on Amazon as a Christmas gift. I purchased a Jamo 201 amplifier to power the two of them and wired them for a mono 8 ohm load. I placed one in each couch in my living room and held my breath as I dialed them in... WOW! Of course I didn't spend any money on the bass shakers since they were a gift, but this is seriously one of the most impactful and inexpensive additions you can make to your home theater. I was simply STUNNED when whatching Batman Dark Knight on Blu Ray, the LFE simply rumbled at all the appropriate times with the Low Pass crossover on the Jamo amp set at its lowest point (50 hertz) If I was to recommend a great bass shaker setup that didn't break the bank I would recommend getting a Dayton APA150 and place a couple of the Aura Pro bass shakers in my couch(es) You can even find the Dayton amp on sale for around $90 shipped on ebay refurbished from partsexpress. The bass shakers actually give the illusion of additional audible bass, I can actually turn off my sub and the bass shakers fool me into thinking I am hearing the LFE bass. Sidenote, I simply split the LFE signal going to my sub amp to feed the signal to my Jamo amp powering the bass shakers.

sounds like there is either a setting you are missing on the receiver, or that you are plugged in to the wrong output on the receiver.

The general statistic is that for every 1 person that complains openly, 26 stay quiet about their issue. If you look at the Sub 10 and 12"s that are for sale for a steal on craigslist and ebay, many of them have the "dead amp" issue. I myself was able to find about 4 being sold locally in the past year just in my local craigslist that had dead amps. This problem is pretty wide spread in my opinion.

Well how does the new woofer sound?!!!!

Wow!. Some of you guys expect a lot from a budget sub. These things are punched out in big quantities to keep the price down and let those on a budget have a taste of true high fidelity sound. You just can't utilise the kind of quality control you would expect from individually hand built products like the Heritage or Reference range of speakers. In saying that, there is no reason why the sub's problems can't be sorted for very little expense. Replacing the sub amplifier sounds like a good option. Just to put your situation into perspective, other manufacturers have quality control issues too. I recently owned a pair of ATC SCM50 active studio monitors for a year. These things are VERY expensive and are used in many of the top line recording studios in the country. I had problems with these speakers from day one, with one speaker making intermittent clicking and cracking noises. I had this speaker back to the technician for warranty work four times. Each time the technician kept the speaker for several days. This speaker was so heavy, I couldn't trust a courier. So I transported it myself with each round trip to the workshop taking several hours. This was very frustrating. Eventually the problem was fixed. While the ATC's sounded absolutely fantastic when they worked, I had reached the point where I was fed up with them so I sold them. Now I just use my Belles. P.S. I also own a Klipsch SW-450 subwoofer. I've had no problems with it. Why not replace your Sub-10 with a SW-450? Edwinr- I see your point, but find fault in it. Was your problem with the ATC speakers one that is wide spread and a known as a big issue with the speakers? The issues with the Synergy Sub-10's and 12's is wide spread, and has been one that has turned off many consumers that were just trying Klipsch out for the first time only to end up with multiple issues with their subs after only a year or two. It should not matter how much you spend on a subwoofer, it should last longer than its warranty period. I don't know about your experience, but spending up to about $500 (Sub-12) is not considered a bargain basement/flea market buy, it is an investment! I have not been disappointed in Klipsch previously, but with these subwoofers Klipsch has fallen into conversations that do not help them sell more of their good product.

I guess I should have explained better. My power goes out periodically, and my worry is that with the sub amps being ON all the time that I would leave the amplifiers open for damage when the power kicks back on. These sub amps only do about 600 watts MAX each, so they are far from overloading this power strip. Better to be safe than sorry in my opinion, use the idea if you like.
