Aura Bass Shaker Pros (1 Viewer)

Who has the best price on the Aura Bass Shaker Pro models?

I am already aware of the PE sale on the 25watt version, but they are underpowered in my opinion...

Thanks in advance,

Keith

Anyone??

Look at it this way - you can buy a BUNCH of the $15/each ones from Parts Express...

I've got four under one couch, and I'm thinking of either wiring couch #2, or putting four more in the back and sides of couch #1...

 

[Keith M.]

Yeah, but that route does not fit into the dedicated HT wiring scheme. I have 1 speaker wall plate installed and am using an AudioSource mono block to power these. Using multiple cheaper shakers requires a very high ohm load or a more expensive stereo amp...


Thanks for the suggestion though...


Anyone have a good price on the pros?

Keith
There is a fella on EBay (phoenixbaymart) that is selling them in pairs for $74. Get your shakers here
Hope that helps ya out

Using multiple cheaper shakers requires a very high ohm load or a more expensive stereo amp

You can adjust the parallel/series wiring of multiple shakers so that the amp sees a 4 ohm load.

1 pair in series = 8 ohms
2 of the 8 ohm pairs wired parallel = 4 ohms
2 of the 4 ohm groups of 4 shakers wired series = 8 ohms

Then finally, 2 of the 2 ohm series, wired parallel group of 4 wired series parallel to 2 of 4 of 8 grouped in 2s biamped seperately to see 4 ohms with a zobel network = hurting my head.

hehe

If you have a 2 channel receiver, can you bridge them?

Chris:

My mind is now fried after reading that post!


I think Ill stick w/ 2 Pros.

Ive been checking ebay, but they never show up when Im ready to buy.

Ill check right now!!

Ok, this is my first post here. (Is there a forum I should
post my 'first post' in?)

I havn't checked pack at PE, but I did remember that there
is a store that sells the Bass Shakers pretty cheap. But
they are the 25 watt (RMS) version.

Don't worry - Chris _really_ made my brain hurt... and I've been reading about power tapering for a possible line array... Hmm...

I've got two 8-ohm units (each two shakers) under my couch, and they're paralleled at a 100 watt plate amp for a 4 ohm load. Amp is turned _maybe_ a third of the way up. I could parallel each pair (2 ohm "units") and then series 'em for the same 4 ohm load - Chris, would there be a difference?

What is more important than "raw power" is making sure that they're securely bolted to the furniture. The small ones fit nicely - dunno about the larger ones.

I was running 'em off an old Marantz 2230 - Only thing you really need to do is make sure that your amp/receiver works down to 20hz and puts out around 25 or so watts per channel.

 

[Ned]

How much shakin' do you get from the pro units?

 

[Chris Tsutsui]

Hmmm...

2 ohm + 2 ohm = 4 ohm
8 ohm paralleled to 8 ohm = 4 ohm

I think it will be the same, but am not 100%.

Get the Aura Bass Shaker Pros from Partsexpress. ~$25 each. Search for part number 299-028 for the black and 229-029 for the grey ones.

Is there such a thing as supplying too much wattage to the bass shakers? Their wattage ratings are pretty low 25/35 watts for the standard bass shakers and 50/75watts for the pro version.

I'd like to use a couple on an extra channel of my 110 watt(8 ohms)amp, but I'm a little concerned that exceeding the wattage rating may cause problems down the road.

 

[Eric Hargrove]

Kevin,

I wouldn't worry too much about over powering the Aura Pro bass shakers, they are I feel very conservatively rated. I am driving mine in series off of one side of a QSC RMX2450 with no problems. Just don't get carried away with your gain controls.

 

[Kevin McCurdy]

Eric,

Thanks. I don't have any gain controls on the amp (Harman Kardon Signature 2.1) I plan on using.

I intend on splitting the LFE channel between the subs and bass shakers, so the only gain control I have would be through the preamp (Lexicon MC-8). The sub levels are calibrated properly and I typically don't listen anywhere near reference level so I'm guessing I'll be alright?

 

[Eric Hargrove]

Kevin, given you don't listen at ear splitting levels, I think you'll be fine.

 

[Kevin McCurdy]

Eric,

Thanks again. I'll order two and try them out.
