Which 21 would be your first choice for a low tuned reflex ?
A budget and a more expensive option?
Lets say f3 in the mid 20s upper cut around 55-60 so strictly a sub sacrificing upper extension for maximum boom down low.
Also not trying to compromise on the size in the process so it could very well turn out to be a 500-600 liter box.

NSW6021
21NTLW5000
SAN215.30
Besides those you could also look at ipal, but as you know, works best with ipal amp module.

I just received a 215.30 to test against a 214.50. Note that its not a BR, but of course still curious.

The nsw definately sims the best, could be because its 6ohms. But largely unavailable in Europe it seems atleast where i looked and the price is a bit steep.
The NTLW caught my eye but dont know why the really low weight puts me kinda off ,only 12.5kg . I know that doesnt need to mean anything but well Smile.
Now the Lavoce is really interesting regarding price and specs didnt even take that into consideration.
Thanks !

The NSW indeed is very expensive in the EU. The NTLW is really nice regarding powercompression figures because of their VC design. Note that the Lavoce offering is almost identical to the discontinued RCF LF21N551.

Also note about the NSW. Its not that good because of its lower nominal impedance, but just overal performance: big VC, Powerhandling, Motorstrength and excursion capabilities.

The NSW is available from Thomann's, albeit with a 3 month wait - and a huge price tag (£1,111!) to boot.

Oh, and why it must be a 21? There is a phenomenal 18 inch from BMS that is actually made for infra duty.

Will take the 18sound into consideration ,
I guess you mean the 18n862, looks interesting.
Why 21 ? I guess it's a matter of size atleast it seems logical it would be easier to go low and loud with a 21 than an 18.
Luton not in the UK...
