Set a Low Pass Filter and High Pass Filter(lpf/hpf) at lpf 40-50 Hz and the hpf at 20 Hz. Both of the filters can be a Butterworth 18 dp slope.

If the amp for the shakers has crossover filters, do it in the amp.

Thanks again Derrick. I did more research and found out that the crossover mode on the amp sends a LPF to one channel and a HPF to the other channel but its only from one source which wont work for me. Im currently using one channel to drive my center channel and wanted to use the other channel for the bass shakers.

Is there any other way i can use a LPF for the bass shakers ?

I just received my first bass shaker and amp to power it. A Buttkicker mini-LFE and a DaytonAudio APA150 amp. Not exactly sure how to set it up.

I haven't screwed it to anything yet. Just wanted to see if I can get it shaking.

Didn't start off shaking, but finally, it did. Surprised how little shaking it did produce. Maybe once it is screwed to board and the board is screwed to the chair, then maybe it will be more pronounced. Or maybe I have hooked it up wrong. Not one hundred percent certain that I have it right.

Unplugged the line connections to an existing sub and plugged them into the amp's L/R Line Input. Then connected the amp's left speaker black output to the shaker's black pigtail, and the left speaker's red output to the shaker's white pigtail. Stereo selected on the mono/stereo switch. On the low pass frequency adjustment, I have it turned all the way to the right. The low pass selector switch on FLAT. The front Level Adjustment all the way to the right.

If anyone can offer advice, that would be quite useful.

Talked to Buttkicker. They said that I needed a pre-amplifier. That the subwoofer voltage on my subwoofer preouts was probably like 300 millivolts. And that the Dayton Audio APA150 needs 1 volt. So I need to boost the volts. So another part to buy.

Been looking at pre-amps. Hard to find one that may or may not do the job. As far as I can tell a "phono" pre-amp most contains a RIAA curve which kicks up the lowest end by 20db and tapers off. Which may be real good or real bad.

If anyone knows of a good pre-amp, please let me know.

You can boost the signal from the ADA-150 using a stereo line preamp part no. 58-14820. 15db of boost max
Made by MCM Electronics but just google the part name and part no. You can get one from Amazon, but it's
cheaper from MCM.

I dont know way you need it though. I powered 4 Aura pro bass shakers off a 240w Dayton amp,
which was connected to only the left lfe output on an HSU-vtf-3. The 150 watt Dayton ADA-150
should easily drive the butt kicker mini without a voltage boost on the ADA amp. If the sub you have
doesn't have a line output, just use a y splitter on the input, and run that the the ADA amp.

Anyways good luck, butt kickers/bass shakers are a lot of fun and add a nice
dimension to overall bass experience.

Thanks for your reply. The way Buttkicker explained it to me, the Dayton Audio amp was barely "hearing" the AVR's pre-out subwoofer line, and that I needed to boost the line-in (to the Dayton Audio amp) voltage.

I'll buy a part (or two) and see if that helps.

Well I found out (by reading my owners manual) that my AVR puts out something like 2 volts on the sub pre-out. So I am beginning to doubt that any problem I might be having is caused by pre-out low voltage. But still two pre amps are on their way.

Tried the Buttkicker mini-LFE again tonight. I put on my bass demo disc. Played LA Battlefield. During certain scenes, the mini LFE was shaking a whole lot more (than yesterday when I was playing the opening of The Man From UNCLE). But still the Level Adjustment on the Dayton Audio APA150 amp has to set to the maximum.

The maker of my two subs (when asked if my supposed low voltage pre out would be any problem to the subs) said: "Most modern home theater receivers put out ~1.2V....If you need more signal for the Dayton amp you can lower the gain on the MFWs. The knob on the front of the APA150 can be turned up to the maximum setting. Think of it more as turning down the level coming in rather than turning up the volume." Don't know exactly what that all means.

I'd say that so far, I am underwhelmed by the MINI-LFE.

I'm sure that some people here have been here before. I would appreciate your input.

Please and thank you.

Are you using it on one chair or a couch? The mini is good for gaming seat of chair. What is your sub trim?

This will be used on a single recliner chair. Have not mounted it yet. So far I am just holding the Buttkicker. My sub trim (on my AVR) is set to +6.

Very happy so far. Even my wife (who is NOT a fan of my bass-exploits) said she was very pleasantly surprised by the mini LFE. Her preconceptions were that the Buttkicker would be jarring. Surprised her that it was just a natural progression of the home theater sound. She has even heard the idea of me adding a Buttkicker to our sofa, and she hasn't objected. She hasn't agreed yet either.
