Thanks guys. I will try this over the weekend. Great advice! Resistance measurement is 4.2 and 4.3 ohms for the pair. Guess that's the normal tolerance.
I would have ordered 16 ohm but they only...
Hey guys,
I just got a pair of Aquaplas 2450SL (made in Mexico) diaphragms from Speaker Exchange, to try on my 2451h. The note for the diaphragms says "non-centering" and must be installed by a...
Barry,
I currently use a pair of 18" Aura RS-8.1 ported subs to cover 60hz and down. May try some small tapped horns down the road.
Thanks for responding. What accounts for the sharply...
Been planning the next horn since I sold my Edgar 80hz horns. The said two drivers are my candidates, so far. I see that 2023h has sharply rising distortion below 120hz. Is this the case for 2020h as...
Hello Widget,
Thanks for your feedback. The only producer of the 4003 horn is the guy from Hungary. I would hope that by now he has refined his manufacturing and quality should probably be...
POS,
thanks for your advice. I have been listening to three compression drivers WITHOUT horns, just to get a rough idea of their sound signature:
TAD 4002
TAD 4003
JBL 2451 + truextent...
Hello,
From those that have experimented with various horns on their TD4003 driver...
What are the horn options to get good sound from td4003? Clone of original th4003 or would IWATA work?
So...
Earl K,
Thanks for the idea. Worth exploring if I can't get the original. However, since you have a single Dukane 5a540, would you be interested in selling it to me? I also have a single working...
Has anyone compared the 4" Be diaphragms between the 2240-2451 JBL models and if the sonic character changes through the driver models?
Herman
Hello,
I got a pair of Dukane aka Coral M100 drivers (no diaphragms). Can someone recommend a source of aluminum or phenolic diaphragms that fit the Dukane 5a540 properly?
thanks,
Herman
>>>I didn't like the TAD 4002z when I heard it .
Rich, I have the TAD 4002 and I don't really like it either. Too bright, like an arch welder. However, on the JBL 2384 horn, with the...
What's the optimal crossover frequency for the 2384 horn mated to JBL 2451be or TAD 4002? Maybe that will help to narrow down the choice between a 15" or 18" midbass woofer? I plan to use that woofer...
That's one option. Generally, is there a rule of thumb when selecting an 18" that is optimized for upper freq range, like low Le or low moving mass? What should I look for?
Herman
Hello,
I've got a JBL 2384 horn with jbl 2451 driver. This is just a thought: has anyone tried pairing these with an 18" woofer? Say 700hz crossover?
Here's my idea: mobile 3 way system with...
Ivica,
what is the problem with putting EQ on 2451Be (Trex-Be), as opposed to JBL Be (476)?
Herman
Can you please provide more information on the needed spacer? I will use 2451 CD with 2384 waveguide.
thank you,
Herman
So far am leaning towards 2451be+2384 or Radial type horn.
Will I need a spacer between 2451 & 2384 horn combo?
What is the horn model no from JBL 4367? Is it the H9800?
Herman
Guys, thanks for the excellent responces! I'm really amazed by the thoughtfulness and amount of good information to digest.
My first surprise, Ivica, is that the Be Trx 4" diaphram will need an...
Hello,
I now have some 2451h drivers with original diaphragms. My plan is to load them with Be diaphrams and try to make a nice 2-way monitor. 3-way is an option but I will barely manage making a...
I've thought about the mentioned recommendations and, in place, decided to try the JBL 2451H on the JBL horns (were sold together). Just curious, what's the best source for the Be diaphragms, now?...
Thanks for the tip Barry! I would love to hear the SH50’s. They may be very good indeed. I'm in Chicago and if you know of a good way to hear them please let me know. Couple of questions for you,...
Thanks you for the recommendations so far.
JBL M2's: I'm trying to stay away from DSP processors. Nothing wrong with using them for mastering work but for pleasure listening -- I prefer to keep...
Mr. Widget,
Is the 15" coax a dead end in respect to the issue I described?
I have not heard the JBL M2 nor other TAD based monitors or the JBL Cinema 2-ways. Have you compared M2 to other...
I'd like to ask for your thoughts on some possible directions I can take, after having used the UREI 813bx (with JBL coax) for some time now. I feel I can formulate what I like/dislike and maybe the...
