New Ascendant Audio Assassin (budget) subwoofer line is out !!!

[simon5]

Hi guys,

Ascendant Audio new Assassin line of budget subwoofers is ready and shipping is starting.

The intro price is very interesting :
75$ for the 8"
85$ for the 10"
95$ for the 12"

All of them are 4 ohms. They got 15.5 mm of Xmax and 350W RMS power handling. The Assassin 12 is a great drop-in replacement for an Atlas 12 (or an Adire Audio Shiva 12" Mark IV) because the specs are similar.

I'm waiting to see what their high-end subwoofers will look like...
Even IB users will like these guys with the nice IB subwoofer coming...

Nice! They certainly have an interesting product lineup coming out, I look forward to seeing some independent testing of these models because I'd love to use some of those little carbon fiber mids if they are as good as claimed.

I'm helping a friend build a box for one of these. He's looking for a ported box that sounds good for movies with a box size of around 18" cubed. Do you guys have any good box plans or suggestions.

Note: I would just use WinISD myself but I'm not that good with it and don't know enough about what I'm doing.

18" cubed is a bit small if you want to go vented and tune low.

You could go sealed but you'll lose low-end SPL.

You could use passive radiators on the other hand.

My comments are for the 12" driver, what driver he plans on using?

[Ranthum]

He wants to use the 12. I saw the recommended box size for tuned is 3 cubes to 20 hz. I've made a few subs myself, but I just usually use the manufacturer plans(adire audio). Right now he has a yamaha yst-sw015 which is a 6.5" driver in a small ported box, so anything would be a step up from that. I noticed one of you said that it might be able to be dropped into a shiva box. Does anybody have the pdf's still? Thanks.

[simon5]

Yeah 3 cubes tuned to 20 Hz isn't bad, but if you can tolerate a larger box, would be even better.

[Ranthum]

When I said 18" cubed, I didn't mean 18 cubic inches. A meant a cube with 18" sides. But anyway, I was think doing 2 ports. Could somebody please calculate the length for me? Thanks.

[simon5]

Yeah I know what you meant.

To calculate, we need what port diameter you want to use and what frequency you want to tune.

That would be for that 18" cubed box? That's around 2.5 cu.ft if using 3/4 MDF.

I wonder how the 8" would do in the Parts Express clearance 8" subwoofer cabinet (.5 cu ft, $30).

Seems like you could make a nice, inexpensive sub using that.

[Ranthum]

It could be 18" internal, 19.5" external to bring the internal volume up to 3.375 cubic feet, minus the bracing, ports and sub itself. The recommended tuning is to 20hz, but it could be slightly higher. I would like to use standard pvc pipe in either 2" or 3" diameters if possible. Thanks.

Note: I would like to keep the port noise to a minimum but also something feasible.
