Default Question for Aussies - LSK S150 sub or build other?

Im really tempted by the loudspeakerkit S150 sub, for $549.

http://www.theloudspeakerkit.com/ind...fer&kitid=S150


However, I was wondering if its possible to build something cheaper that is just as good if not better than the s150.

This amplifier, for $216, would be similar wouldnt it?

http://www.advanceae.com.au/catalog/...oducts_id=2332

Or the jaycar one I think is about $300.

What woofer would I source?

Is it possible to build better for less money?


Any advice would be much appreciated, thx.

The LSK does have a good reputation and is an easy way to build a sub as all the hard work has been done.

You could build a better one using the plate amp from Advance Audio with the Peerless 10"XLS subwoofer also available from them.

http://www.advanceae.com.au/catalog/...oducts_id=2468

Would cost about the same with some MDF and other bits and shipping is cheap from Advance Audio ($8 only) and when you add in shipping from LSK for the S150. There are plenty of designs around using the Peerless 10" XLS and is a very nice and highly regarded subwoofer.

diy is more fun!

check out http://www.acousticconcepts.com.au/
as they are in melbourne and stock the Shiva 12, Tempest 15 and Adire DPL12, all bone crunching!

depending what amp you choose, they will easily outpower that kit.

so the shiva from acousticconcepts, at $272.50. I dont need to factor in postage as I can pick up.

The amp from advanceae at $216, with $8 postage.

Brings it up to roughly $500.

Then the wood, port, stuffing etc shouldnt total more than $50 would it?

And using one of the adire audio designs, would this subwoofer perform better than the lsk one?

Is the advanceae amp decent? Its rated at 150w into 8 ohms, same as the lsk one.

Or is the 150w into 8 ohms from jaycar at $329 better?

Is the shiva 8 ohms?

Jaycar and AdvanceAE stock 3 amplifier modules.

Same power rating, physical size, even the description is the same. I suspect they are the very same amp modules.

The LSK S250 uses a similiar 250W amplifier module to the 240W ones you mention. It also uses a Dayton 12" DVC driver, which is reportedly a clone/derivative of the Adire Shiva 12" DVC driver.

Depending on your final design it would be a competitor of the the S250.

the advanceae and jaycar amps appear to have the same specifications, but look noticeably different. The $100 difference has me stumped!

i read that the shiva is 4 ohms. The s150 is 150w, so i assume it uses a 8 ohm woofer. Do does this mean I would be getting 240w from the amp?

What are the advantages/disadvantages between 4 ohm and 8 ohm from the amp?

hey todo
same manufacturer, different models
i used to sell them

top one is 240wrms into 4ohm, 150wrms into 8ohm
bottom one is 240wrms into 4ohm, 290wrms into 2ohm FROM 12VDC
as you can see the GND REM and BAT gold screw terminals down the bottom. theyve got their amp pics mixed up, so they are actually identical.

if you can find anyone with an ABN, like busterno1 suggested try wescomponents.com otherwise, whoever is cheaper

yes, if shiva is 4 ohm, you will be getting 240wrms

you can get a 1200x900? sheet of 16mm mdf from bunnings for about $33. the 25mm sheet is a whopping $80? if you use lots of bracing the 16mm should be enough, glue screws etc another $15, should be ok.

guessing by the pics and descrip the LSK S150 uses a cheaper polyprop woofer, which is no match for the shiva. then again maybe go into LSK and demo it?

Unless you happen to be the Supply Chain Manager for an MDF business... Well there's got to be some perks in being in manufacturing

I just bought 40 sheets of 18mm 2700x600mm from my company (Pinepanels) for the whopping total discounted cost of $150AUD.

Now, I've just got to figure out what use to put it all to, hence my perusal of this excellent thread. I've been hangin out in other forums and only just stumbled on to this one.

I've got a Marantz SR7400 AV Receiver and am looking to build my whole 5.1 channels worth of speakers. Thought I'd start with the easiest one, the SW.

So this site is just what I was looking for
