High Sensitvity 92 db 2-way Speakers Using JBL 127H-1 and Dayton RST 28-4F The modern high quality HT speakers tend to have typically 86db/2.83v sensitivity, limited primarily by the relatively smallish woofers used in them. The newly introduced Dayton RST-28F4 has a sensitivity of 93.5db even without a waveguide or horn. In addition, it can be crossed low(1400 hz). I jumped at the opportunity to use it in a pair experimental 2-way high quality DIY speakers with sensitivity around 92 db/2.83v. For the woofer, I just happen to have a pair JBL 127H1 woofers available. JBL
