Three sets of drivers, one cabinet
“This is really high end stuff.” That is Sanjay on his Avalon-inspired floorstander after its latest driver change: Satori TeXtreme tweeter and midrange, with a 12″ SB34NRXL75-8 woofer on the side of each cabinet.
What is in the cabinet now
Each cabinet carries three drivers: a Satori TW29TXN-B TeXtreme dome tweeter, a Satori MR16TX-8 TeXtreme midrange below it, and a 12″ SB Acoustics SB34NRXL75-8 woofer on the side panel. Two ports sit low on the front baffle.
Sanjay, the owner
We have not measured this pair. Everything on this page about how it sounds is Sanjay's own words, and everything about the drivers comes from SB Acoustics' datasheets.
The tweeter and midrange: Satori TeXtreme
Both front drivers are from the Satori range and both use TeXtreme: a TeXtreme dome in the tweeter and a TeXtreme cone in the midrange. The chequerboard you can see on the midrange cone is the weave itself. What the material is, and how it differs from Kevlar and ordinary carbon fibre, is in our TeXtreme guide.
- Satori TW29TXN-B: TeXtreme dome, neodymium motor, 4 Ω, 96 dB (2.83 V / 1 m), Fs 650 Hz
- Satori MR16TX-8: TeXtreme cone, neodymium motor, 8 Ω, 89 dB (2.83 V / 1 m), Fs 35 Hz
Figures are from SB Acoustics' datasheets for the two drivers. Both datasheets are marked as preliminary data.
The woofer: a “Satori in disguise”?
The newest part is the 12″ SB34NRXL75-8. It replaced the SB Audience NERO 12″ woofers that went in with the February 2026 upgrade.
diyAudio has a thread titled “Is the SB Acoustics SB34NRXL a Satori in disguise?” The driver is sold in the SB Acoustics range and carries no Satori badge. What its datasheet does list: a 3″ copper voice coil, an under-cut pole piece with dual shorting rings, 22 Hz free-air resonance, 91 dB and 20 mm of linear coil travel.
Posters there who compared independent measurements put its distortion close to the Satori WO24P's, though not as low. One owner reported THD under 1% below 200 Hz at levels above 90 dB. Those are forum reports, not our measurements.

Three line-ups since 2024
The cabinet has stayed the same throughout. Only the drivers have changed.
| Line-up | Tweeter | Midrange | Woofer |
|---|---|---|---|
| 2024 | SB29RDNC, fitted but not connected | Satori MR16P-4, run full-range | SB Audience 12″ |
| February 2026 | Satori TW29TXN-B, connected | Satori TeXtreme 6½″ | SB Audience NERO 12″ |
| Now | Satori TW29TXN-B | Satori MR16TX-8 | SB Acoustics SB34NRXL75-8 |
It began as a FAST design, short for full-range and subwoofer. The Satori MR16P-4 covered everything from about 150 Hz upward on its own and the 12″ woofer took the bass. The two tweeters were on the baffle as insurance and stayed unwired.
The crossover and the system sensitivity of the current line-up are not given here, because we do not have them.
