Here is TIW300 and other two 12inch woofers.

I do remember seeing the 12" Visaton measuring very well below 30 Hz before (from one of the two major German mag.s). (..though my memory could be "rose-tinted".)
It would be interesting to see comparison of T00-subwoofer and T01-woofer versions.
No, the measurement I'm thinking of was from Hobby HiFi or Klang + Tong, and I'm pretty sure it was measured on a DAAS system.
(..and was also aware of this one above as well.)
-btw, you could get two of these for not a lot more than one SB 12":
Monacor SPH-300KE top HiFi bass speaker 200Wmax 8 Ohm | Loudspeaker freaks
Monacor SPH-300KE top HiFi bass speaker 200Wmax 8 Ohm | Loudspeaker freaks
Of course, and I can get three of:
Peerless SLS 830669 - 12" Woofer - Coated Paper Cone
at lower cost than for one SB34NRXL too[emoji846]
Thanks HiFicompass!
Looking at SB34NRXL75-8 Vs ScanSpeak 32W/4878T01, I declare the SB winner!
SB34NRXL75-8 advantages:
- HALF the price
- Better sensitivity/impedance ratio
- Better on and off axis frequency response below 1khz
- Better step/waterfall
- THD+N is close, but SB looks cleaner to me, and also keeps H3/4/5 lower as level increases. Only concern is this 750Hz peak on the SB, which suggests one should cross at max ~400Hz. (on the ScanSpeaker this peak is 6dB less and happens 50Hz higher)
If I can afford, I ll go for this SB for my next build.

I have a pair of PA460 but to test them I need to make a new large size test baffle. My current test baffle can take up to 15" speakers only. Don't know when I can manage to get a new baffle.
Good drivers, as expected of a Scan-Speak Revelator and Bliesma. There might be more compelling options out there for both units, this thread has spent some time on one such option for the Scan. DSA315 would still be a nice comparison in terms of T/S-parameters.
As for the T25A, it brings super-wide off-axis response into the top octave with excellent distortion performance. The 60 degree off-axis extends clear beyond 20k - incredible! But the T25B seems mostly superior, sensitivity is higher with smoother on-axis and still wide top octave. That could be a simple unit issue, but the datasheet shows that as well. It is also much cheaper than T25B, but so is the nice SB26ADC from SBA.
