I'm renovating a bonus room over my garage into a home theater. My 8 Berkline's will be at the dealer within the week, and I'm going to build a riser for the second row of four chairs. I'm looking at Bass Shaker Pro's from PE, and I had been planning on getting 8 shakers, one/chair.
Couple of questionsI thought I had it all planned out in my head until I started reading more of this thread last night! These are more of the "whadda ya think?" questions rather than the "how to wire so as not to melt the amp with low resistance circuit" questions (at least I think so!)
1.) I had seen jamis's photos (above, #1642) of the Bass Shaker Pro's in the junction between the seat back and the seat cushion and thought that was pretty easy to mount. I had wondered if the placement might be "less focussed" on my tush (i.e., more realistic?) if I went with the board across the metal frame that the Buttkicker retrofit package (http://www.thebuttkicker.com/downloa...uctions_v2.pdf
) uses. Obviously, the BK couldn't fit where jamis put his Bass Shakers, but I'm wondering if the lower mounting point (i.e., wooden plate across the bottom of the metal frame, DIY version for me, though) would lessen the (less powerful than BK) Bass Shaker effect too much. Any thoughts?
2.) Amp question"quick" (sorry) background: I also was going to use the 300w BASH amp that jamis was using, but since my wife wanted to be able to defeat the shaking if she didn't like it, I had thought about a switch setup to turn off either of the two rows or shakers (4/row, 1/chair)after much thought, it seemed like the best way to do it to avoid a low resistance parallel setup was to actually use two
separate amps, one for each row. I was also going to mount the two amps on the back of my riser (speaker wire wall plate on front to connect the front row), so I (a) wouldn't have to go into the equipment closet to turn one down, (b) wouldn't have to run as many wires to the amps (one line level wire) and (c) I could get the amps powered by a different wall outlet circuit from my equipment and not overpower the circuit, etc.
After perusing the thread, I've wondered if the 300w amp for 4 shakers is overkill. I also have an old Onkyo TX-84M stereo receiver (circa 1988yeahhh, baby!) with 60w/channel RMS @ 8 ohms; it has A and B speaker outputsthe manual says "only speaker systems rated at 8 ohms or more should be usedif only one pair of speakers is used, the load impedance must be at least 4 ohms". After reading the posts about page 15-18, it seems that many are pleased with the use of an old receiver to power the shakers.
So, any opinions on my options?
a.) two sets of 300w BASH/4 shakers (two independent amps for two groups of 4),
b.) same as above, but smaller amps, likely go with Daytons from PE (How much smaller would be good? They have 25w, 70w, 100w and 240w)
c.) A/B speaker outs off of the old Onkyo (A for front row of 4 shakers, B for the back)
d.) go with an old receiver or amp, just one with more than 60w/channel (and then how many watts to drive all 8 shakers)?
Sorry so long, but I didn't want to nickel and dime with partial info and multiple posts. Thanks in advance for reading this far!
