I would like to help because I have about 10 of those radios, and one by one the speakers are binding up just like yours did.

However, the speaker is built into the frame of the radio and the Manufacture does not sell replacemt parts for them. In addition, there is really not enough room to mount a replacement speaker of similar dimensions, and I am would be quite capable of doing it myself if that was possible.

I hate to face the fact that my radios have seen better days unless I want to use a speaker mic and I don't because the extra cost, size and weight are not practical to save radios that I can replace with new for just a bit more.

They were great radios, and Motorola should be ashamed that they don't make after market speakers. I'm sure they just want to sell new ones to us.

By the way there are no 'WIRES" to the speaker, it makes contact with the board terminals when you re-assemble the radio.

Hi,

There are no other controls to adjust the volume or tone settings of the audio output.
On speaker replacement, most TalkAbout speakers are not difficult to replace. They are however a challenge to purchase. It might be easier to purchase an off the shelf speaker of same dimensions and construction or those of comparable brands (Icom, Kenwood, Yaesu, Uniden). The only factor to be considered is if the replacement speaker will fit the confined space at the back of the front panel.
Alternately, you can just use an external speaker/microphone rather than purchase a replacement internal speaker, opening the unit up and do some minor soldering.
If even with a replacement speaker and/or an external one, the issue remains, it is possible that the unit has an internal electronic fault in the audio amp, demod, IF stage(s).
Hope this be of help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.

Audio seems weak...how to increase volume


this is gotta be the largest complaint I hear from folks when they get a new flat screen , its not loud enough or the sound sounds muffled

flat screens are flat ! so theres no good way for mfg to put the speakers facing forward so sound has to hit the wall behind it first then gets directed forward to you ! (low/muffled)

sound bars help with this , but for true rich sound , id go with a video receiver amp combo , some of these even have built in dvd players , and arrange its speakers in a forward facing direction

When I first got my phone the alarm was working fine but now it just sounds muffled and I tried everything what can I do to make it louder again?


How does everything else from the speaker sound? If everything else sounds muffled, then there might be an issue with the speaker itself, which isn't readily repairable. If everything else is fine, check and see if the sound is coming out of the correct speaker. I am assuming you've adjusted the alarm volumes and rebooted the device...

At low volume it is fine after you get to about 20 on the volume it starts to crack,pop and distort very bad what is making this happen


Your speakers may say 350 watts but that is the peak wattage at which they blow up and not a wattage they can sound distortion free at. Look for the RMS wattage which is probably around 40 watts. If you look at the specs on your receiver you will see it will put out a maximum of about 50 watts but the distortion on the receiver is above 1 percent at anything over 22 watts. That means they are going to start distorting at around half volume. The other thing you might check for is a impedance mismatch between the speakers and the receiver. Is the receiver set up for an impedence output of 8 ohms but your speakers are 4 ohms impedance.

Ue boom connected to pc but is not playing music... if i get lucky i get muffled sounds play back, how do i fix this


Q: What should I do if the audio is distorted or drops out on my UE BOOM?

A: Audio distorted or dropping out when streaming to UE BOOM
If you're having trouble with audio distortion or drop-outs on your UE BOOM, try these suggestions:
  • Move the audio source closer - it might be out of the range of your speaker.
  • Move away from other sources of wireless signal - you could be experiencing interference.
  • Make sure your speaker has enough battery power (connect it to a power source with the supplied adapter).
  • Adjust the volume on both the audio source and your speaker.
  • Restart both your speaker and the audio source.
  • Re-pair your device with your speaker (see, "How do I pair additional Bluetooth® devices with my speaker?").
  • If you're using two UE BOOM speakers (for Double Up), try disconnecting and streaming to one speaker only.
NOTE: If you're streaming audio content from the internet, the issue could be with the internet connection and not your speaker.

My 10 inch kickers sound distorted not clear at at and muffled


Does the enclosure volume and style/type match the sub requirements? Are the subs wired correctly? I've seen lots of marking on the wrong terminal. Try switching one of the subs from pos to neg and neg to positive. It will be dramatic and very noticable if that's all it is.
Is your cutoff frequency correct for the sub? Make sure they're not getting full spectrum frequency. Are the Subs physically hitting any part of the enclosure at any point in the excursion? Are they screwed securely to the enclosure? Is the sub surround intact and smooth through the full extcurion? Is the amp ok? Got enough current throughout the system? Battery, Capacitor, Wiring, fuses, speaker wire etc. Bigger is better but always the correct fuse rating.
Signal from the head unit? Proper preamp wiring?

Sound is muffled


This may be exactly how it was designed, large TVs are usually made to be connected to a sound system or sound bar to get decent sound.
Check that there is no dust in the speakers, when sound is up slap the speaker area, if you hear a rattle or any change there may be dust or dirt in the speaker area, use a vacuum cleaner to remove it through the speaker grille.

Suddenly, my outdoor speakers sound kind of "muffled"


If these speakers are two or three way speakers, it is possible that the tweeter(s) are blown in them.
Try and remove cover to check.
If the sound is not distorting, but just flat and muddy its the tweeters.
Put the other ones on this channel, to make sure it is not the amp.

Laptop Sound Problem - Muffled!


The DVD players in laptops are asked to do alot. First I would try is that movie on another DVD player - wtch closely to see or here any abnormalities in the the same location. Your DVD laptop player may very well be bad. Better to get it checked out under warranty. When you take it or send it make sure you tell the tech where exactly the movie goes muffled and if you can send or give the movie to the tech.
