Hi everyone!
I'm currently planning a construction of a cabinet for 2 x 10" woofers for an outdoor bass application. I would like to hear from you what you think about it.
I'm trying to find a high efficiency woofer that can go down to F3 = 50 Hz - 60Hz.
I'm currently using this SPA-10A/250NEO for my design. I have a 77 liter cabinet and it is tuned to 62,5 Hz. I think the response looks fine.
The VAS for the speaker is only 19 L so is the cabinet too large? I'm thinking of filling it with some dampening materials if that will help?
Another question: The datasheet says xmax of +/- 3 mm. Will that mean 6 mm in WinISD?
I've added some pictures form WinISD. There is added filters (2nd-order highpass @ 40 Hz + 2nd-order lowpass @ 400 Hz).

Thanks for your help,
Simon H.A.

If you mean in the WinISD Driver Database, then no, it means Peak = 3mm. Peak to Peak = 6mm.

If you go to Options in your design, you can select to show between Peak/P-P/Rms by clicking where i've placed the arrow 😉

What do you mean when saying "elements"?

He means the weather, rain etc.

Okay thanks. They are not going to constantly be outside, but some protection is added. I've changed the xmax now. But I'm still able to get almost the same response without breaking the xmax so that is good. Are there other drivers that you can recommend for my build?
