Hello. I'm new, and have an idea.

Hello.

I guess this is my welcome thread.

Anyways.

I've built a few speakers, ranging from small bookshelfs, to the cyburg sticks.

Now, both were made from MDF. Each time I cam to a point where I realized that they would need a finish. I eventually HAD to paint them, because I cannot veneer anything for my life.

Now for my next project, I would like this to be a speaker that will last me quite awhile. I would like to try an open baffle design.

Specifically a design that resembles Nomad audio's Ronin speaker.

Now I'm really not that great with straight cuts, as I don't have a table saw. So what I'm wondering, is:

Will the sub that will be installed provide sufficient bass if the sub is open baffle and not in an enclosure?

Thank you.

Depends on how wide the baffle is, 1/4 wavelength is a way of getting an idea. if the baffle was say 9 ft wide it would probably be able to recreate a quality 30-35 hz note easly. 80 hz or 60 hz are probably a better smaller target to aim for. Im sure someone here can explain it much better than me.

Hi, the short answer is no,

Another way of doing it :

David at audiocircle.com has developed an OB with -3dB at 29Hz.

sreten, what kind of drivers were used in those?

That looks very similar to the OB's I want to build (MTM, under 4' tall). I'm still selecting drivers and tooling up, though, so I haven't really built or tested anything yet.

Welcome wafflesomd, that sounds like an interesting project! I would second sreten's suggestion of separate sealed subwoofers if you aren't interested in making your own cabinets. Something like the ones available at PE : http://www.partsexpress.com/webpage....ctGroup_ID=535
Keep us updated on your project!

Regards,
David
