Hmm... I wouldn't use this driver above 2kHz (and that with a 4th order LP), given the shelf in on-axis and the dropping off-axis. Doesn't seem to be a very good performer in the bass, so the SS 10F/4424 (8424) overall looks to be much better as the mid in a 3-way, or in a 2-way the full-copper-sleeve SB drivers are superior as well.

I agree. A disappointment. I'm in the market for a mid that is as good as the PTT6.5. The PTT4.0 fits the bill except that I'd like higher sensitivity. This is not it (nor, IMHO, is the SS 10F). Rumor has it that Purifi will release a mid at some point. That would make me really happy.

SB12CACS and 10F4424G are absolutely differently intended speakers. One is a woofer and another is a fullrange. So, the comparison doesn't have a sense.
The cone materials are different, so the sounding is very different too. Apples and oranges...

I'd definitely use it. Crossed over sharply at 2.2kHz with Seas DXT and at 200Hz with SB23NBAC ported or RSS210 closed. Passive for upper and active for lower crossover point, of course.

Although the 12CACS performance isn't bad the motor clearly isn't in the same league as that of the 15BNAC.

I'm glad that SB actually added a shorting ring to the CAC Vs SBs other 12 series drivers but am still at a complete loss as to why they don't go with the copper sleeve of the 15 and 17.

Yeah, you'd think the "xAC" series should all have them... oh well. Missed opportunity.

Have you compared the SB 15/17 N(B)AC, CAC, CRC, MFC, NRX2?



I've always been curious about they sound
I have a SB15NBAC and MW13PNW.
I'd like to EQ them to within 0.1dB from in their useable frequency ranges (50Hz to ~2KHz) and compare them via listening.
No tweeter

Hi, may i ask if you prefer a specific cone material sound ?
Personally i think that aluminum has a big potential for really great sound
thanks a lot

Yes, one day I compared CRC, CAC, MFC and NRX.
I would place them in this order by my personal taste:

1. CRC and NRX
2. MFC
3. CAC
