Note it's not actually smaller subs that is they key - basically speaker bigger subs are better. The key thing is multiple subs.

More than one sub allows you more placement options to even out the response that will be not optimal with a single sub due to room modes etc.

Yea, I was indicating that if you have four XLS10 drivers, then four subs, each with a single XLS10, would probably be better than one monster sub with four XLS10s. Of course, four monster subs, each with four XLS10s would be... loud.

By that are you saying fullrange speakers are preferable compared to letting subs cover a larger portion of the range? Maybe just using them to augmenting the very bottom octave?

As Rich indicated, the reason for using multiple subs is that you can even out bass response. There's some info on multiple sub placement at the following link: http://www.audioholics.com/tweaks/ge...or-bass-part-1

Somewhere on Audioholics there is a much better article, specifically on multiple sub placement, that looks at the optimal number of units (4 IRC), and positioning (but I can't find it right now).

There probably is a good argument to use speakers down to, say, 80-100Hz, then use multiple subs for everything below that - as you can place all the units in places that will give the best response.

Remember I've done a fair bit of room treatment and measurement.. though admittedly not with subs.

Isn't that going to look pretty much the same as you started out with the silver? I like the red and black!

Its going to be a similar but darker hue and less pronounced. I'm hoping it will providing less of a contrast with the black and blend more.

Its too late for this project but I'm just getting into the custom painting side of things. I tried my hand at it for the first time today but it didn't go particularly well. It was a checker pattern with a transparent orange colour fade over a coarse silver metallic integrated into 50% of the checks alternating with black checks on the other 50%.

Did I say it didn't go very well? It looked poor because I hadn't masked correctly, I hadn't used the right masking tape as it lifted the paint in places when removed and I was using a full size gun instead of a detailing gun so had overspray all over the place. I can see the potential though and these things come with practice. I'll certainly post something when the results justify it.

I applied the baffle colour today and was a little disappointed after spraying a few test coats onto scraps of inkjet photo paper. This grey mica that I'm using is nice looking under direct or sun light but looks like primer in regular domestic light - not good.

To save face, and not begin a colour swap shop, I added 75g of Auto Air 200micron sparklies per 1ltr of the grey mica. The result was much better after that. Its not in your face but adds a little something to an otherwise overly subdued metallic grey.

In spot light or direct light the baffles look interesting but not overly overt and in low light the baffles virtually disappear and attract no attention, which is perfect for late night, quite listening where you'll want to hear and not see the speakers.





In direct sunlight the sparkle is fairly intense, I tried to capture it with the camera in these two shots but it just looks like a wash of white rather than the shimmering surface the eye sees.





Here's a shot taken with the flash to highlight the sparkle particles that have been added to the paint. It never looks this over the top to the eye but thought I'd take that shot just to give you an idea of what's going on.

Looks very nice to me Shin, and I think that the grey will be easier to live with long term than the red.

Now, are you a paintslinger or a speakerbuilder? Don't forget you need to have these ready for DIY2008.

Ah, finally someone that understands.

I'd have to say cake eater above either of those two. And don't be daft, DIY08 is an entirely unrealistic goal.

Yup, he'll have sold these and be about three projects down the line!

cake eater mean in the UK?

p.s. I generally don't like painted speakers, but yours look fabulous.

It means someone who consumes vast amounts of sugary goodness, which sounds like a good plan to me.
