Hi there audio guru's!
This is Mark. Few years ago I own a good pair of JBL 4425., but I have no choice but to sell it that time since I need money and I still have my JBL L-100 century.
After few years, I'm missing the sound of the 4425's.
So a week or two ago. I looked for my JBL 2416H-1 compression drivers and JBL D130f 15" full range speakers on our storage. I tested them and they are working good.
Now... I want to make a speaker out of those drivers.
So I searched searched and searched until I reached this great forum.
So for almost a week I back read most of the pages on this thread. (im not yet finished until now)
I'm impressed on how dedicated are the Guru's sharing their knowledge and making all the efforts to make test and shootouts.
Too bad as I've read Mr. Zilch already passed away.
I hope there's still someone out there who can help me with my project.
I just want to ask the following:
1) Do you think I can implement the idea of econowave using the D130 and 2416H drivers?
If so..,
2) Please recommended waveguide type (horn) for jbl 2416H
2) Please suggest a best suit crossover schematic for these drivers.
D130F is a fullrange 8 ohm version / 15" with more than 100db sensitivity (i think) rated at 25W
2416H is 8 ohms with around 100db or more sensitivity / 50W /
TIA Everyone!
Hi Mark!
EconoWave is also about "affordability".
So I have to ask ( before recommending anything );
Where do you live & ( as a consequence ) how is your access to in-expensive parts ?
Remember that the mid/woof must have sufficient margin at ca 2kc or higher to be usable with the recommended compression drivers, regardless of the LF capability. If the crossover region doesn't stay clean at expected drive levels, the midrange is not going to sound good.Collet was loose apparently. Gouged the hell out of the front. I don't think they can be salvaged. I think I'm going to go with modular design. Separate cabinets . Thinking a 2 car ported sub cabinets and 2 smaller cabinets that hold a 6x9. The sub cabinet something like 1.5 cuft portedto 35 hz or so.
Thinking this 12" one. Then just redo the baffle to recess the driver a bit.

and this 6x9 cabinet.

Wish I had better wood working skills. I can modify a cabinet. but never been able to build a good box though.
OK, good!Yeah useing the dayton dc250-8 10" woofer. It's not a subwoofer. The subwoofer cabinet would be used as a ported speaker cabinet. Gotta put the driver in something and that will do the job and is inexpensive.
Hi everybody!
I need help with a crossover. I repeated Econowave by coreyk78 post #11720:

and now I don`t know which crossover will better for me? What You can say about Critesspeakers CS-1.5 crossover:

Yes, I tried to contact with coreyk78, but he does not answer. And now I do not know what I should doBut that's not what you built.
You appear to have built a copy of coreyk78's work / therefore I suggest you continue down that choosen path and use whatever crossover he used ( unless he was ultimately unhappy with his choice ?? ) .
According to the info I read in other posts ( after the post that you linked into ) he used the High Sensitivity version of the crossover .Yes, I tried to contact with coreyk78, but he does not answer. And now I do not know what I should do
Thank you for the crossover scheme. But I am a newbie and it`s will my first speakers. I would be grateful if anyone upload photos of crossover. I don`t know which Crossover Components I need?According to the info I read in other posts ( after the post that you linked into ) he used the High Sensitivity version of the crossover .
So this is the one he used ;

I recommend building it up and going from there .
- Remember, one can directly add capacitors together ( paralleled ) to get a new value .
- Plus one can string coils ( inductors ) in series to directly add their values .
I can't really find a photo for either of the 2 JackGiff crossovers ( previously displayed ) showing them as assembled , but here's the next best thing.Thank you for the crossover scheme.
