Ricci Posted May 10, 2019 Share Posted May 10, 2019 Parameters, notes and pics of this woofer have been posted. Looks like another good 21" pro unit so far. This is one of the smoothest modeling 21's in bandpass and horn enclosures and it directly competes against the B&C units so it will be interesting to see how it compares. Suspension was extra crazy stiff on the pair of woofers I have. Even after some break in the Fs is almost 10Hz higher than factory spec. Guess I'll have to rerun it after beating on it for a years or so. Link to comment Share on other sites More sharing options...
Kyle Posted May 10, 2019 Share Posted May 10, 2019 Nice sub, lots of BL. Pretty much BL^2/Re over 300 is norm now for these 21's Link to comment Share on other sites More sharing options...
SoundOfTheSaint Posted June 17, 2019 Share Posted June 17, 2019 Hi Josh, I see this is the 8 ohm version you tested, do you know how the 4 ohm version compares against this one, specifically for use in the Othorn? I already own the driver and got the 4 ohm version so the amp can provide enough power but i'm a noob sandwich when it comes to this stuff Link to comment Share on other sites More sharing options...
Ricci Posted June 17, 2019 Author Share Posted June 17, 2019 It should be very close except for the impedance difference. The 2 impedance drivers model almost the same. Link to comment Share on other sites More sharing options...

radulescu_paul_mircea Posted June 23, 2019 Share Posted June 23, 2019 It seems that 21ID can take a tad more thermal input with a bit less power compression than 21NLW9601. 20% more power and 1dB less power compression. But it has higher distortion doing that, something I noticed. We need 21NTLW5000 tested here for a complete package Link to comment Share on other sites More sharing options...

But it has higher distortion doing that, something I noticed. We need 21NTLW5000 tested here for a complete package These 9601's appear to be more similar to the B&C 21SW152 and slightly older generation drivers than the SAN214.50 / 21DS115 drivers. What I mean by that is these are a little bit shorter stroke but with a lot of power handling. Makes sense because these have been around for a while. Good drivers but they do not have much past the 14mm xmax rating. It's much less of an issue once they are put into cabs that limit the excursion like they are intended for. Yes the 21ID is rated at exactly the same xmax and power handling as the 9601 but it appears to have a little bit more of both based on the testing.

SoundOfTheSaint Posted June 24, 2019 Share Posted June 24, 2019 Glad we now have some more data on these, would the weaker performance at higher excursion of the 9601 make the 21sw152-4 a clear cut winner in an Othorn doing 25-80 at high power(upto 4000W~ per driver) in a PA setting? Or in real world use is there not much difference between them? Really tempted to try and sell my 21lw9601 and use 21sw152-4 instead as I can get them £100 cheaper each than the 9601, i'm really interested in how these drivers compare and any advantages of using one over the other.

I don't think the 21SW152 really offers much more excursion than the 9601. Maybe just a bit. Overall they are fairly comparable. Whichever is cheaper should work well. I don't think either would be a noticeable upgrade over the other. Link to comment Share on other sites More sharing options...
ojedadavid Posted July 14, 2019 Share Posted July 14, 2019 Would the inuke 12000 at 2ohm be to much for a pair of 18NLW9601? 4ohm bridged, two 8ohm subwoofers. Inuke 12000 1100 x 2 @ 8ohm 2700 x 2 @ 2ohm Link to comment Share on other sites More sharing options...
Kyle Posted July 26, 2019 Share Posted July 26, 2019 Seems reasonable, too much is never a bad thing either, just means it won't clip. Link to comment Share on other sites More sharing options...
