It's okay. SB29NRX has early cone breakup than 23NRXThe driver I have used was the SB29NRX not the SB23 NRX.
The SB23NBACS45-8 is a bit better up to 1500Hz.The woofer duty will be assigned to SB 23NRXS-45 -8. Cabinet volume will be around 38-40 liters tuned to 35-40 hz. Here is the link to the woofer
Closed box 38L (stuffed), Qtc=0.68
Yes true. But I already have a pair of SB23NRXS45 from a previous buy. Moreover if we consider the crossover point to the dome midrange( around 600-800 hz) then it will not make much difference. Tonality match if we consider, I guess norex cone will be a better choice with the dome midrange. Thank you for your input. Have you heard the dome midrange drivers DM7500 or DMN-A from HiVi?The SB23NBACS45-8 is a bit better up to 1500Hz.
No need to say sorry. Your intention was to provide a better suggestion and I understand that. I am reading that thread of dome midrange. Thank you once moreSorry, I do not know the hivi domes, but you can try to search info in "the dome midrange thread".
