Topic: JBL 2445
Posted By: noiseboy
Subject: JBL 2445
Date Posted: 10 February 2008 at 11:34pm
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?

the ASS cabs in my avatar where loaded with 2445, they sure did throw well. and yes they sounded good. one mistake was selling them.

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

Hi Colin,I have a pair of these horns I think,they certainly look the same as whats under those Dare grills.
I bought six of them for my Dad,(couldn't resist as I got all six for £50!!) to use for his outdoor film shows, as the horns he had before were slightly overkill.(4' long ).
He was using all six Missen horns loaded with JBL 2446h drivers but we soon figured that was too much and now he uses three.I decided that as there were three spare, I'd nab a couple of the horns and use them for my soon to become audiophile style home system.
Can you tell us any more about the horns ?Mine look like there made from MDF but I could be wrong,Fuzzy.

yes Trevor did make some in mdf and also some half and half (the tops were mdf and the sides ply) he also used a lot of dif.... drivers but mostly jbl or beyma, all the horns were hand made (something trevor was very proud of) using a small jig and a lot of resin W,

they were also used on a variety of cabs, the NX12 was the largest (2 x 12" +hf) the NX10 which was a 2 x 10" +hf  and a mobile system with 2 x 8" +hf, all used the same horn and only the NX12 was a full box (the rest were a cab with a bloody great horn on top)
 
all the systems came with a missen eq (a bit the bose unit) except most of them only crossed over between the mid/hi and bass & also did the eq for the horn
the system I sold Chris  consisted of
4 NX12 1200watt mid/hi's
4 TCB 1200watt tripple chambered bass cabs (but 2 got stolen)
2 x 1200watt quad chambered 2 x 18"
all JBL loaded
a total of 12k and it was very Hi-Fi but brutal when you wanted it to be
but to be truthfull I've not found a horn to match it yet for quality

Not JBL TCB's were they?we have a pair of those also.Maybe thats what I'll use on the bass end of my home system! .Ive yet to hear the TCB's work properly as when we first had them they were loaded with Eminence sigma pro's... sounded pants, took about three outings to pop one.They are now all correctly loaded with JBL 2240's.
The horns do sound sweet,very HiFi.The six I bought were flown in a nightclub around the dancefloor,in skeletal form.I had to make some crude boxes to protect them.Not one of my finer moments but it was done in a hurry!I'll dig the camera out and take some pics.

No not the JBL tcb's (totally dif cab) although in the right place the JBL's sound ok, the Dare/missen tcb's were a bit/lot bigger (as in the pic) and went really low (24hz) ok for short to medium use but not a stadium system at all, really designed for nightclub systems we did an install in a club in redhill and 2 tcb's & 4 NX10's (with a bit of infill) covered about 1000 people so they did work but with the 2 x 18's as well the effect is proper "in yer face" ( and chest, pants, , hair, etc)

The TCBs We have are 2x18,although I did buy a pair of the 2x15's as well, the old man uses one of the 2x15 tcb's in the local arts centre as there isnt much space.
The 18's are for sale,unfortunatly as they take up too much room.I would have them but i can't get them through my front door .I always thought that they were gonna do the the business, but I seemed to be a bit dissapointed every time I heard them.I suppose there were two good reasons for that,Bandpass+outside and Eminence.I since built four V18 loaded X1's (which do fit through my front door).They produce the scary bass I was hoping the JBL's would,and have always been smiling when using them...even outside.

The only thing I can say with the JBL's is you have to drive them hard! then you'll get the est from them but their still not going to chuck the sound to far, but it will be deep!

cheers Colin, thats probably a better photo than the one I was going to post, shows the horn out of the cab, I'll maybe put some measurements and dimensions up to give an Idea of size.
  A very nicely made piece of kit, infact all the Dare cabs Colin sold me, are really well put together with fantastic craftmanship.  I guess Trevor Missen to be a bit of perfectionist!
 So far the short throw of the cabs hasn't been a problem, as I'm mostly running indoors at a medium sized venue approx three hundred capacity. The  system performing well in conjunction with my existing rig and certainly no shortage of  bass!  bourne out by the blurring of the video image in time with the bass player or the kick drum!  Not sure how we get round that problem, perhaps have to turn it down a bit during filming!

I didn't have to many probs with video, this is short film of a band my brother promotes/manages (pArAdox) this was the day before you picked the system up! first time I had used the camera and didn't know up to that point it even did video the, system was soundcraft LX7 desk missen xover running on 1 x QSC plx3402 on bass & QSC plx1602 on mid/hi so the system wasn't even running to it full extent, bloody loud though even outdoors! the playgroung was about 200 yards long and the bass was unreal but the top did drop off a bit at 150 yards

are the Link Dynamics CD1000 the same driver as the jbl 2445?..


Posted By: _djk_
Date Posted: 12 August 2017 at 10:31pm
No, it is not a good value, even though it is cheap.

The Link (and Image) Dynamics products originally tried to copy JBL and Altec products, got sued for patent infringement, and then changed the designs so much they became quite poor.
