Just pondering..... I have some JBL 2445 drivers, big meaty 100w compression drivers.matched up to large flared horns.
They certainly look high quality, heavy duty.. Are they rated as a good driver? I've only used them once so far(for a high powered heavy metal gig) and they seemed pretty good to me. I've no previous experience with these drivers. Do my ears serve me well? Opinions? Cheers Chris |

These drivers are very good. Although they roll of towards the top end, this can usually be corrected by taking out the rise and falling reponse which is the main characteristic of this driver. In other words, if you flatten the response , they will sound great. They are very efficient.

If you want lots of 1-10kHz then they are the driver for the job. Maybe not the most hi-fi but pretty good with some EQ. If you're doing metal bands etc, one of those above a couple of 15" drivers will do very well.
The only downside is how damn heavy they are. Separate boxes for mids and highs methinks! |

To be honest when I'm doing Heavy Metal Bands I spend quite a lot of my time inside my total isolation headphones to protect my ears! I just keep popping out to check the mix.
I reckon most of the Heavy Metal boys can't hear much above 10k anyway. After a few years of Metal thier hearing is shot to pieces! Especially the drummers! |

2445`s are rated at 120w from 800hz upwards,but as Chris says,use them from 1k up...i found they sound sweetest at 1.1kz crossover....what flares are you using them on?..could you post up a photo?

Intresting stuff guys. My own thoughts too, were that they are not all that Hi Fi, therefore I haven't really tried using them for the more gentle lower output, intricate, acoustic, folk type music.
They certainly seemed to perform well at high levels on Heavy Metal and Rock Bands. I will try a bit of experimenting/fine tuning with EQ and crossover points though. Cheers |

Umm..one very important point....its essential you have the genuine diaphramms fitted to get the best out of these,then they will sound ultra-hifi crossed around 1.1khz on the correct horn.....if they are fitted with the cheap copy diaphramms they sound dreadful.

Oh right that's a very useful tip, I have sort of made an assumption that the driver being to blooming big it wouldn't really have the agility to sound HiFi . It's nice to know these are a really decent piece of kit and I should definately spend a bit of time fine tuning,with a real possibility of much better results than I'd hoped for.
I'll try and get some photos up of the horn flare, see what you think of the design. |

I think chris is refering to the horns in these:
hand made plywood flair with a JBL 2445j made by Trevor Missen before Dare was sold to Sammy De Havaland (sorry if I've spelt your name wrong Sammy)
the horns work really well but have to have the C.D. EQ

Never criticise another man until you've walked a mile in his shoes. Once you have, call him what you like, you're a mile away and you've got his shoes!
