Last NS-1000 version before the ultimate NSX-10000.

Unlike the "last" which usually means "best" or "even better", the NS-1000x is actually more an updated NS-1000M than a refined NS-2000.
The NS-1000x was also priced accordingly : 158,000¥ vs. the 108,000¥ of the old NS-1000M or the 228,000¥ of the NS-2000.

Upgraded from the original design was, naturally, the carbon woofer (with an NS-1000M diecast frame but sans front grille) allowing a lower frequency response (39Hz vs. 40Hz) with a resonance frequency placed at the same lower limit : 39Hz for the 1000 and 40Hz for the 1000x. Said 30cm bass unit has edge-wound OFC copper voice coils and a 10,500 G flux density.

The 4,5cm high-density particle enclosure was largely reinforced at 42kg (vs. 31kg), and covered with real walnut veneer painted in black (NS-1000x) or left natural on the x-rare and pricier NS-1000xw (175,000¥).

Already added to the NS-2000, 16 gauge OFC filter wiring was kept for this lower version of the NS-2000 and better version of the NS-1000M. The filter is a less complex than that of the original design and certainly less expensive than the one in the NS-2000.

The "in-line" arrangement of the drivers was retained from the NS-2000 although the assymetrical system of the original NS-1000 doesn't seem to have bothered the many owners...

The mid and high Beryllium drivers are slightly different versions of those in the NS-2000... or NS-1000. As for all NS series loudspeakers, bi-wiring wasn't deemed necessary or useful.

At the time the NS-1000x was launched, two zeros below, a beefed up version of the 1977 NS-10M started to invade most recording studios on planet Earth.
No Beryllium there but worldwide success just the same. Numbers-wise, if the original 1000 is still abundant to say the least, the 2000 and 1000x are far less common - the 1000xw being of the ultra-rare kind.

The 1000x was used by Luxman as "reference" speakers as late as 1997, along with a pair of JBL K2 M9500.
