SB acoustics kits.

The SBA thread

I'll also sell the demo drivers used to develop the M5W and the finished crossovers (SOLD). A nice savings for a great kit.

Regards,

So, the SB kits I think are terrific values but my other kits are outselling them by quite a bit. Anyone have any feedback so that I can develop speakers with these drivers to appeal more to a larger audience?

Do you think the reason for this is the SB drivers are pretty new and not as known as Scan Speak and Dayton/TB?

Just looking for some feedback if you get a chance let me know what you think.

Not sure really - I don't think I'd attribute it to the unknown factor; I think it's probably more of a design factor. Personally, I think the M5W's look like an awesome design for the money, but the slanted cab is a little intimidating. There is no denying the appeal of the Dynamic series for those that want big, imposing, multiwoofer speakers at a reasonable price without using "cheap" drivers. On the other hand, the high-end people are always going to drawn by SS drivers.

Thanks, I think you hit the nail on the head with your feedback. Here I was just going to work on a design with another slanted baffle. The thing is I really like 2nd order slopes... as was used in the M5W. The crossover worked out really well and that speaker sounds great. If I went with a straight baffle, I'd have to go with 4th order or an electrical delay circuit shallow slope. The SB 5" driver requires a few extra parts to begin with to shape it into 2nd order because of it's peaky top end, so going straight baffle would require an electrical delay circuit to get that nice flat power response that 2nd order provides (even more parts and not as elegant).

So overall the design goals would totally change with the flat baffle. Not saying it couldn't be done but there are reasons why I used the sloped baffles in the designs that have it. 2nd order just sounds better when the drivers can handle it.

"...2nd order just sounds better when the drivers can handle it..."

Just curious,
in what way would one recognise the better sound of a 2nd order x-over? And what would explain it?

"...So, the SB kits I think are terrific values but my other kits are outselling them by quite a bit. Anyone have any feedback so that I can develop speakers with these drivers to appeal more to a larger audience?..."

For me, both the slanted baffle and the width of the enclosure were turn-offs.

2nd order crossovers have a smoother power response. If the crossover Fc (frequency cutoff) is in the presence region of 1-5k where the ear is most sensitive, I find that 2nd order crossovers have less of a signature or peaking that can cause some brightness with the same Fc if using higher order crossovers. There are other ways around this, and realize I'm generalizing but that was the basis of my earlier statement.

Also, thank you for your feedback. Aesthetics are definitely an important factor and big wide speakers are not "in" so to speak... even if its functionality is stellar. For some it's a fair tradeoff.

Well, I would not want to mess up the sound just for a few inches, so I would stick with the design. Actually, by the time I get around to it, I might feel richer and go for the model with premium drivers. People with money now might be insulated from Financial stress and there for this value line is not moving.

Thanks

Most of my sales have been to Canada and Australia recently. Also, the 4T and 4CC are the hot sellers. Big, narrow, and good value speakers are "in." I can't blame them though!

Jed,

For those that think the M5W is too wide, what about 2 RS225 -4s in series? Sensitivity is pretty close; i don't know if you have wiggle room in the BSC or attenuation on the mid you can mod...

That's a good idea. Could do an WmtW tower that should be rockin'. Could do it in a nice rectangular box for ease of construction. Anyone on board?

It'll need about 100Liters or so which isn't exactly small but the narrower width can hide some of the visual mass.

that could be really cool, IMO. Too bad the SB ring radiator tweet isn't available yet.

I know. I've been eager to get my hands on it to see if I can use it in some of my existing designs. That way there will be a soft dome and hard dome version so people can select the tweeters for their tastes.

Hey Jed,

Madisound showing SB29 in stock now, just in case you're interested....

Thanks for the heads up.... I'll likely order a pair next week to try out along with the 4" and 8" drivers.
