best speaker to use??

im hoping to get exorays sound kit soon but i was wonder which is the best speaker to

use with it?

im hoping to use a 6 to 9 inch car speaker with a decent bass which ones do you guys use

i dont want the sound to be let down by a rubbish speaker,

i expect it to handle the deep bass like in the movies

obviously the main things to consider will be size, power etc

also which way to face it? i plan on putting it behind the cyclotron lights do i face it towards the lights or the other way round and drill some holes in the motherboard and have it face my back?

Since i am interested in this as well, i’d like to ask another question.

If using a chip like the one from Replica Props, what size amp is good to use? 5W,7W,20W?

I used a 3-Way 6x9 Kenwood speaker. The mid and high range speakers built in to it really help.

They only come in pair, don’t they? And that was a really good question about the facing. Towards the cyclotron or the motherboard? (I would quote Fight Club but this is a G-rated forum. ;))

I’m not an aficionado when it comes to audio equipment so I don’t have a suggestion for “best speakers to use” but . . .

I can help with this question. I have 2 4" speakers in both my packs. Here’s a shot of the one I’m building now:

I have one facing each way. There’s one mounted underneath the PCB that the cyclotron lights are mounted on facing out towards the shell, and the other speaker is facing down, towards the motherboard. I also have holes drilled out through the motherboard for the speaker that is facing it.

Now is that the best way to do it? I have no idea but I atleast get alot of surround sound doing it this way, instead of it all being in one direction. I hope that helps a little.

Firstly if you want to use 2 speakers you cannot use car speakers.

Car speakers are 4 ohms limiting you to only one speaker. The best pack I’ve ever heard has 2 4" Bose home speakers at 8 ohms each (totaling 4 ohms).

You want a speaker with a small cone which requires little power if you want it to be loud, the larger the cone the less it will push and the less you’re gonna hear it.

If you face the mobo, you need to drill holes in the mobo so that you can actually hear it, just like Matt did in those photos.

That’s extremely interesting, Vincenzo. Thanks for the info.

So would it be possible to put 2 small 3-way speakers, for example? Or would it be best to put one tweeter and one woofer? Are those home speakers available in 3 or 4-ways?

Whether the speaker is 2-way, 3-way or 6-way it’s still one speaker and is rated as such. In any case it’s kind of wasteful since all we’re playing are mono sound effects recorded at kind of poor frequencies (due to the nature of the chips/ardys).

Here’s a pretty well worded breakdown of “OHM’s” if anyone wants more info.

The one everyone uses is the 7w found here http://www.electronickits.com/kit/complete/ampl/CANUK153.htm

It is unique because it can handle the pre amplified signal from the www.replicaprops.com sound module. You run the speaker out wires on the sound module to the pins labeled “G” and “WIN” on the amp

Looks at 600W 10" sub on the counter…

Looks at pack…

Hmmm. LOL

make sure you use a speaker that can handle a lot of bass and wont crackle with the low hum of the startup or vent sounds.

Not saying my method is the best way to go, but my pack does sound fantastic…

Here’s how I embeded the 6x9. A hole was cut into the plywood Mobo so I could slip the highs and mids into it and let the woofer sit flush onto the board.

Then I mounted the electronics chip from Replicaprops onto a piece of cardboard with a breadboard foundation.

You can see the 7 watt amp Rob Werden was talking about…or at least the controls here, underneath the injector tubes. There’s a volume knob and a power switch I added so the amp wouldn’t run itself down all day. I just reach back there and turn it on when I want to use the sound, and can adjust the volume without taking off the pack.

Here’s the speaker highs poking through the board

My pack’s not the prettiest but I’ve made people jump out of their skins when I powered it up. They’re usually not expecting such a loud rumble coming from a prop!
