So a buddy ended up with an extra IBeam Bass Shaker from his HT build and perma-loaned it to me but I have no way to power it.


I need at least 100 watts RMS but can have up to 250W RMS at 4 ohm according to the manufacturer's website.


I need a relatively inexpensive way to power it.


What should I get? Jamo MPA-101/201 around $100 used? Buttkicker BKA1000 around $250 used? Some sort of plate amp?


Thanks!

I would say a plate amp to give you an extra degree of crossover control. You might not like the IBeam playing the same bandwith as your subs. Plus the buttkicker is way overkill power wise for the intended application and probably cost the most.

Be careful with the amps from parts express. Most have a built in high pass filter and that will defeat a lot of the purpose of having a tactile transducer anyway. Find a good full range amp that will reach down to 5 hz.

Reaching down to 5H hz is confusing me a bit.


I've been looking at monoblock amps:

JAMO MPA 201

Marantz MA 500

NHT SA-2 (not a monoblock)


JAMO states "Frequency Response 20Hz ± 5K - 20Khz"

Marantz states "Frequency response 1 W 10 Hz - 100 kHz ± 1 dB"
http://www.marantz.com/pdfs/u_amp_ma500_bck.pdf


NHT SA-2 states "Frequency Response: 25Hz ? 150Hz, +/-3dB."

What should I be looking at to see if I can get down to 5 hz? Are all of these unable to do it?

Most modern electronics have filters built in at around 10 hz but can still have usable output to 5 hz. If you have a lower crossover setting on your receiver you could use a single channel of an ep2500. Its only $300 and has plenty of power left over for when you want to build your own sub.
