Jbl everest dd55000


hello, I have some everest dd55000 and I would like to know if changing the drives for some tad 4001 would improve my sound?
Thank you

First things first. Treat the room first then say there is not enough bass. You guys shoot first and ask question later. Spend your money on a little education FIRST that will cost you a little time but NO MONEY.. Then you won't be spending money good after bad.

Learn how to use some great inexpensive tools to learn what you need to do first. 

I assure YOU it will pay great dividend in the end..

I owned a few JBLs. Rythmik and GR are my ONLY recommendations with those speakers. All of the bottom firing sub are worthless unless they are slot loaded and decoupled.. JBL makes a great speaker, don't screw it up.. Caps, resistors, inductors and coils, is always a good idea.

Get a book, take some measurements, Treat the Room. HiFi 101.

Most of all enjoy some of the best speaker ever made..:-)

@suso There are many exceptional subs made by a number of companies that specialize mostly in making subwoofers.  For example SVS, Rythmik, REL, JL Audio, HSU and the list goes on.  You will find lots of useful information on subwoofers if you do a search here.

 

 

 

@suso Said!

could you put a subwoofer or would it mess it up?

Yes No!

JBL made a matching pair of subwoofers for the Everest model DD50000 see manual above (low frequency). A JBL B460 subwoofer would be great with the Everest.

@fiesta75, All good I agree on the subwoofers.😁

Oh yeah!! I have a passive jbl tik model, but how could I connect it?
Or would I need two?

ditusa - Thanks for the info on the DD55000, I stand corrected. I just figured since the DD67000 were charged cap networks these may also be. Also, correction: These were made from mid 80's to 1989. In my opinion a couple external subwoofers would improve the sound of even these great speakers. You are missing quite a lot of sound below 25Hz. Have fun.

hello, thanks for your advice, I'm really very happy with the everest, I just notice maybe a lack of bass, could you put a subwoofer or would it mess it up?

I’m pretty sure these are charged capacitor networks. Check the manual, maybe change batteries 

 

No! See below:

I would not change drivers. In fact if you’re not going to do the crossover caps yourself, don’t bother replacing anything. They were made in the mid 90’s so no need for new capacitors yet. If you’re not enjoying the sound, sell them 

@suso,

Look for a TAD TD 2001 compression driver it has a 1’’ throat the Everest DD55000 horn is a 1’’ throat. The Everest DD55000 compression driver is a JBL 2425H.

Stupid idea! It would kill the resale value of the Everest's. Crossover would have to be changed.

The JBL Everest and the TAD 4001 are top tier products. However the TAD4001 is not a direct replacement for the driver in the Everest. At least without a careful crossover change and measurement. This would be a project for an advanced hobbyist. 

thanks for the answer but I don't understand what you recommend, sorry but I'm not a technician in that

I'd leave the drives and replace every cap and resistor in the crossover. I wouldn't be surprised if there are complete crossover replacements available.
