DIY 4x10

[Myth_103]

Hello again TBers. I was looking for a new project to play around with, and since the neodymium speakers had such a crazy jump in price, I figured I'd look into Eminence's other speakers. I've been playing around with Win ISD and plugging in stuff for the Eminence Delta 10B. It seems to have a decently flat frequency response to begin with. Do you guys think a 410 with these in a 7ft^3 box tuned to around 55-60 hz would be a good place to start?

Hi.

Unless You're planning to make a vertical 410, there's little or no point in reinventing the (bad) proverbial wheel. IMHO anyway.

And YES, I play through a conventional 410 and YES, I sometimes even pair it with a 115 .

Regards
Sam

+1, especially as the Delta 10B has only 1.8mm xmax, making it almost useless as an electric bass driver. Frequency response is only a small part of the equation.

If you really would like to start the challenge of DIY cabs then consider to make 2 2x10" (vertical aligned) to be able to transport it since "NON neo" speakers are not lightweight.
And consider also the Legend BP102 (4 or 8 ohm) if you want "robust" basses....don't forget a midrange to cover frequencies from about 600 Hz on (where BP102 lacks).
Otherwise there is the "used" market....

Regards,

Roberto

Sam You're gonna go straight to Hell!!!!

I was actually planning to vertically align the speakers, and the website I read said there was an Xmax of 3.5mm. If I were to use the bp102s, what would be a mid driver that could cover that dip on the frequency response well?

[Myth_103]

Besides, bp102s have a very low spl and take a large box.

The Delta 10A has 3.5mm xmax, not the Delta 10B. No offense, but if you had the ability to design your own cab you would not be asking these questions. And getting the information from WinISD or the like only gets you about 1/3 of the way through the design process. A well designed speaker cabinet is a lot more than just a box.

[Myth_103]

None taken whatsoever, Bill. It's all just a learning process.

[Myth_103]

Also, since I don't personally design or build speakers, what other factors could I control than the box? My understanding was that cabinets needed to be designed well around the speakers that you were intending to use for your specific purpose.

I see you have an SVT-VR. My guess is, you picked the Delta 10B because you want a 4ohm cab, and that was the only 16ohm 10" "bass driver" you could find. You've got some company there... might want to check out this thread.

When you're in WinISD, look at the "maximum power" view in your model. That should show the displacement limitation to which Bill referred.

That's going about it backwards. Your first consideration is pack space; the best cab in the world does you no good if you can't get it to the gig. When you settle on what's the largest cab (or group of cabs) you can comfortably manage you model as many drivers as possible in that size cab, then compare the results to see which gives the best results based on your tonal needs, your instrument, and your amp. You also have to compare the raw driver data sheet SPL charts for response above 200Hz, which is not predicted with software. Then you have to figure out how to build it so that it works as well as possible. With a 4x10 that creates a problem from the get-go, as it's probably the worst speaker configuration there is. And here again, if you don't know why that's the case then you need to do a lot more book learnin' before you make any sawdust.

Copy the compartment size of the SVT fridge (they are 4 compartments of a pair of speakers each), load with eminence B810, put two end to end. That should be good, simple and practical.

Thanks, Bill!

A practical approach, but that would be an 8ohm cab, and the OP's amp (SVT-VR) has 2 and 4 ohm taps.

I'd like to see someone do a vertical 4x10, with wheels and a handle, and with a space at the top to mount one of the new mini-heads. Break the mold and set a new standard.

It won't happen from a major manufacturer. They build what sells, what sells is what's familiar. Introducing something that doesn't fit the cookie cutter mold is too risky. Small outfits like Duke, Barefaced, Acme and to some extent Avatar, with relatively low R&D costs, and practically no marketing and distribution costs, can bring out innovative products. Ampeg et al? Fageddaboutit, they don't lead, they follow. If and when some small outfit sets the world afire with a vertical 410 then and only then would they offer one.

Time to get working on that design seamonkey. Set the world on fire and set a trend.

True dat. Avatar didn't introduce the 153 until consumer demand arose as a result of the fEarful. Moreover, the initially proposed 3015LF loaded Avatar cab was hooted down by the fEarfully educated, and didn't come to market at all. The 153 resulted from suggestions made from this site.
What's not known by the masses is that DIY loudspeaker technology is at least ten years ahead of the mass market produced goods, and always has been. DIY speakers are to Ampeg etc. as Burt Rutan is to Boeing, or NASA.

Looks like I have an exploratory project over the holidays.. Concerns would be the total cost of the guy, especially if non-Eminence drivers are involved, and sonic comparisons to the fEARful..
