Which SB woofer (or alternatives) for a 35liter sealed box crossing at 500-700hz.
SB29NRX75-8 is fairly new I think with no hits on a google and gives the same profile in WINISD as the WO24P-4, is 8ohm, has a larger SD, a couple more mm Xmax and looks like a more benign breakup but drops 3dB in sensitivity.
Has anyone heard or worked with the SB29 8 ohm, what do you think ?
Which would you choose, if neither then what else ?

I've used the WO24 in a similar sized sealed box. It is superb. I would recommend it without reservation.
@cowanaudio, thanks for the reply, any chance you can tell me a bit more about your speaker? Did you use the 4 ohm version or the 8ohm.
I'm curious too. Cause I have two SB23NRX - but more want more 😀
Thought about both the WO24, but also going for something else like the Dayton woofers - since they should be able to work in smaller and closed boxes, for at more precise and smoother off-rolling bass.

I can 2nd that about the Satori WO24. Its a pretty good sealed box woofer and appears to have very low distortion, even at higher excursion. It also works well in vented applications and goes down flat to 28 Hz, but i haven't used it much that way as i prefer sealed enclosures. The lighter cone makes this a fast sounding driver. I'm using the 8 ohm version x 2 in parallel per side in a 3 way with Scan Speak D75MX41 and Audax TW025A28 crossed over at 900/3.5k in aperiodic enclosure.
Thanks for the responses, looking promising for the WO24P.
@profiguy, sound like a similar set up to the one I am looking at - WO24P-4 sealed in 35l box for Q=0.7, Morel EM1308 dome mid at 600hz and Wavecor TW033WA10 for tweeter at around 3.5-4khz. Crossover is acoustic LR2 across the board (via active crossover). All this in a 70’s inspired Monkey box with golden ratio (1.62:1) internal dimensions. The 600hz bass/mid is what Troels used in his SBA941 and the 35l is what Jeff Bagby used in his Helios but with a SB29 passive radiator (a later option I guess). This all models very well with phase pretty much coincident for at least 1 octave either side of the crossover points (more like 2 octaves).

I used a pair of 8 ohm drivers in the bottom of a Watt/Puppy type loudspeaker, Satori drivers on top. Top and bottom boxes were actively crossed. The woofers had 65L sealed.
I use an SB34NRX75-6 in a sealed box, active crossover with 250W amp, 20 Hz to 200 Hz.
It seems that the SB34NRX75 and the SB29NRX75 are very similar, one being a 12" driver and the other a 10". Based on a casual observation, I would guess the motor is basically the same.
If the 10 is as good as the 12, but slightly smaller, I think it will serve you well.

I hve a pair of SB29NRX75-6, and they work fine n sealed box!

The best 10” I could see that goes up to 500-700Hz in a small 35L is the L26ROY. Excellent distortion and bandwidth.
If you can have bit more cabinet volume I don’t think there’s anything that beats the 10” Scan Revelator 26W/4867T00.
The SB29RNX75-6 looks ok but i haven’t seen any non-linear distortion measurements on it. The
The Peerless XXLS-P835037 has F3/F10 of 48/28Hz in 35L sealed, but again, I haven’t seen any measurements of that either.
Any oldie but a goodie-
The original Peerless XLS; won’t go as high as 700Hz but excellent as a subwoofer up to 200Hz.
What's old is NEW again. Peerless XLS in sealed box, F3= 23Hz -

Thanks again for the comments.
I did look at the L26ROY but it is not very efficient compared to the WO24P-4 and as you say the Peerless looks good but only to about 400hz.

I'm using the WO24P-8 in a line array. Sealed enclosure, around 30 liters / each. Works great up to about 700-800 Hz.
On each panel about 5 cm polyesterfiber+ middle of the enclosure one additional 5 cm panel with a density of 40 kg/m3.
Thank you. I'm currently experimenting with some thick long threaded wool for my midranges, instead of felt and other synthetic materials. Seems like the way more fluffy and thick(heavier) wool dampens the enclosure better.
One cabinet was filled with the wool and the other with the old material - and just by using my voice, you could actually hear that the wool dampend the enclosure better. Not scientific - but gotta start somewhere 😀
