"There is no such thing as "speed" in speakers."

I don't necessarily subscribe to the fast bass vs slow bass language that is used all too often. However, I have run a function generator into two different woofers, one being a heavy cone, low FS subwoofer driver and the other being a light cone higher FS midwoofer driver. At the same frequency (and only that one frequency) and the same volume output, the two woofers sound different. It seems that the heavy cone woofer has a damping(?) effect on the higher frequencies (in the hundreds of hz).

I don't know what you call this, but there is a noticeable difference, and I prefer the lighter cone for reproducing the higher frequencies. For this reason, I would think that midwoofers would be best for midbass, and the subwoofer driver best for the low frequencies.

I still have a pair of them, working push-push in my subwoofer - gets used daily for my HT set-up. Was a bit sad to see them go OBS. Not sure what I'd be able to replace them with if I broke one.

The new CSS is resurrecting some of the NLA CSS woofers. I have my eye on SDX7 & SDX10.

No 8" though in the case of my Trio8.

I used a pair of the LDW7 which I understand is a drop in replacement for many kits built with the earlier SDX7.

Shame they are not doing their old small fullranger. Was quite popular from what I read.

Id look closely at the alignments. Due to the abrupt running out of excursion i never liked using SDX7 in any vented enclosure.
