My Energy CF-70 fell down today on my carpet floor - The speaker seems to power up and working but there very obvious difference from other front speaker. I would say muffled or low sound ?
Which is the best way to find what is the issue with speaker?
How much it would cost to repair the speaker? Any suggestion for B&M repair shop as shipping cost are very high for such a big speaker?
Is there any I can sell the speaker?
Thanks for your suggestions !!

I would first inspect for visual damage in the drivers
then maybe remove one of the cones if I could tell where it's coming from, may be as simple as a solder broke and a wire fell of inside

If you are at all handy, you could check a few basic things. Play some full-range music through the speaker and make sure each driver is producing sound (put your ear up close to each one in turn.)

If any are not producing sound, you have found your problem. It could be a damaged driver, or it could be a loose connection from the crossover. I don't have CB70's, but the crossover for most speakers is normally inside the cabinet near the binding posts. Most often, taking the driver closest to the floor will give you access to the crossover. Look for disconnected/broken wires.

As the previous poster mentioned, you could also have knocked one of the wires off one driver, so you can still isolate the problem the same way.

Good luck!

Mike

I just checked my speakers - It looks like the tweeter is not producing any sound... I can hear sound from other 3 drivers...

Start by checking the wiring inside the speaker. Pull the driver out, and check it out.

Then contact Energy about replacement cost etc. Hopefully it's just a wire has popped off, and you don't need to spend anything to fix.

Many years ago my 55KG (121 lbs) Roti x Doberman decided he wanted to see what was behind one of my speakers... Speaker didn't stand a chance, and my heart sank. I know how you feel! frown.gif

Don't worry though, provided the cabinet is OK, and it seems to be then it can be fixed.

Looks like the issue fixed by itself.. The tweeter seems to work fine now.. probably a loose wire connection to the driver ! So happy now... Thanks all for your help/advise... biggrin.gif
