MGO Posted February 6, 2021 Posted February 6, 2021 (edited) JBL 2451H Compression Drivers with 2381 and 2383 horns included. 2381 are fibreglass and 2383 solid cast aluminium. These have 4" diaphragms with 1.5" exits. Neodymium magnets. The smaller 1.5" exit and waveguide (as opposed to horns) give extended high frequencies. With a bit of eq will get to 20kHz without the need for a supertweeter. Diaphragms are original JBL titanium 8 ohms. Work flawlessly. Edited February 7, 2021 by MGO 3
