The Poor-Man's Subdude

The talk about the Subdude made me experiment with DIY my own since I discovered I had some material lying around. Really all u need is 2 items: the platform and the feet.

For the platform you need something rigid. I remembered I had a piece of 2'x2' 20mm granite slab spare. You can also get MDF board or plywood, etc. But the real key item is the feet. How do I know this - because I first experimented with just putting the granite slab on the floor and the sub on it. Not much effect since nothing to absorb the vibrations (the granite is after all very hard).

For the feet I remembered that the packaging foam that came with the FCC 2 was a very firm/dense type. It's not styrofoam (too hard) nor the usual type of foam (too soft & airy). So I placed 2 pieces under the granite. The result: sub is less boomy now, bass is tighter, my plaster ceiling rattles less. In fact I'm able to turn up my sub volume. Previously volume at 35 was the threshold before ceiling rattles. Now can push to 40, so can enjoy louder! This validates the effect of the real Subdude and also demonstrates that it can be DIY easily (of course I'm not saying my DIY version is as good as the real thing). The key is to find the right foam.

Here's the pic of my poor-man's Subdude:

[attachmentid=985091]

I am going to meet up with one acoustic foam / industrial grade foam supplier this week. I will take the subdude and show them since I saw that their products are near identical to it. Maybe can produce something similar to Auralex but at 'affordable' price (if there is a market for this). I do hope that I don't make life difficult for other hi-fi shops

Turns out there is Speakerdude from Auralex, but it's too small for my fronts.

What I do is get those cutting board from Jusco (RM 15 per piece) which is quite heavy and solid. Then to raise it from the floor, I use those silicon feet you you get from DIY shop (for chair) and stick below it. Imaging does improve a bit. Previously I had problem where my speaker is not really stable on my carpet due to uneven pattern plus thick rubber underlay.

You mean those wooden vegetable cutting board? Good idea.

Do you find those silicon feet provide enough isolation, compared to a big piece of foam underneath? I'm thinking what to experiment with next.

Can I show you mine?

I use the soft ball toys. Under the Sub & players.

Wow! So far the best DIY idea here!      Now I think I better go & buy some ball for my Para sub. I have try form before, didn't work as it is too heavy, now it is sitting on 4 thick book.
Do post up so more DIY project. Saving some $$$$ is always my aim. Tq very much & have a very nice day to all sifu here.

jwjy, it would be no match for your SPL lah. Everytime audition SPL-1200R, I felt my CHT-12R is underpowered Must hide mine
