"Le bouledogue" (The bulldog) a very fun project with the SLS P830945 and SB26STCN

Thanks for the summary, I will stick with the SLS woofer

Had a look at the crossover. If you don’t mind, why did you use the sink hole (cap and R parallel to the series coil) in the woofer circuit?

Nice build

Thank you ! ( I forgot this)

@markbakk Yes I use precisaly this circuit to suppress the peak, to don't mind of it.

 

[markbakk]

Check! I didn't notice the (resonance) peak at give or take 2,5kHz. It's not that usual for a paper cone.

 

[jerome69]

This resonnance peak is the dome resonnance of the driver near 4kHz. For a 5" it usually higher. This driver is usable till 3kHz. If you look the directivity till 2.5kHz.
There are too much marketing in the loudspeaker market with products line, range to sell more ? and we should never trust manufacturer data. The 830945 is a rare example of better than specified. The specs recommended 50-1000Hz, I use it in the range 40-3000Hz.
