Panasonic RX-ED90 Cobra Top




Alright, so I may be pushing it a little here by calling this Panasonic RX-ED90 a vintage boombox. But, it was manufactured in the mid 90's which is now almost 20 years ago so it is definitely bordering on vintage. And, while it does have a CD player it also has two cassette decks. The values of some of these 1990's CD playing boomboxes have been climbing steadily meaning that people are collecting them and they do have their place on a site such as this. That being said let's get to the details.


Panasonic RX-ED90 Cobra Top


The RX-ED90 is also referred to as the Cobra Top. You can see from the picture above why that is the case. The flip top display and control panel look vaguely similar to a cobra's head when in the upright position. I believe this model was the last of the flip top line and some consider it the best.  Below you can see the two cassette decks inside the flip top panel area. Both decks have auto reverse.




The illuminated control buttons and panel add to the look of the RX-ED90. The box has what's called a Spatializer for 3 dimensional sound or S-XBS.




The Spatializer even has its own LED display on the front panel that pulsates with the music output which this model pumps out at about 86 watts.

The ED series of cobra top boomboxes consisted of the RX-ED50, RX-ED77, RX-ED90 and RX-ED707. They also manufactured a flip top line under the RX-DT designation as well. Many feel the RX-ED707 is the best sounding of the ED series, but you'll find quite a few that prefer the RX-ED90 as well. Some other features of the RX-ED90 are:





The Panasonic RX-ED90 does have an Aux In line so you can hook up your iPod. And, as I mentioned earlier it has both a CD player and cassette players so different media formats won't be a problem with this unit. Most functions on the unit can be controlled with the remote control as well. However, while the tape decks doors will open via the remote they must be closed manually as they are not motorized.




If you like the looks and styling of the RX-ED90 then you'll probably want to take a look at the RX-ED707 as well because it has the same cobra top but the speaker grills give it an alien look.




The ED series of boomboxes including the Panasonic RX-ED90 are fast becoming very collectible. Since they include CD players and Aux In lines for mp3 players they are very useful. They are built well and sound great as well. Prices have been climbing for units in good condition. In fact, an RX-ED90 in mint, out of the box, condition sold for $1275.00 in August of 2014. Obviously that's a top end price. Models in used condition or not fully functional can sell for a couple hundred dollars. Overall they are great boomboxes and prices are climbing.

Here's an interesting video showing some of the functions of the RX-ED90...


Williamsons AIE 2000



Here's a pretty rare boombox. It's the Williamsons AIE-2000 Enviro Stereo and I would guess you probably haven't seen one before. While it may be lacking a little in the style department it does have one feature that sets it apart from other boxes. It has seven speakers. Yes, 7. It has four speakers on the front including a couple supertweeters, a speaker on each side and a large 6 x 9 bass speaker in the back. It was made around 1985 in Hong Kong and was probably never sold in the U.S.



It does have a Line In if you want to run your MP3 player through it and it also features:

  • 3 way operation - AC, DC 12v or batteries
  • 7 speakers
  • 13.5 Watt RMS
  • Direct radio-to-tape recording
  • 2 electret condenser microphones
  • Auto shut-off
  • Sleep timer
  • 2 4-way VU meters
  • Pause
  • ALC and variable sound monitor
  • 6 wave bands
  • Bass + Treble controls
  • Mic mixing
  • AC bias
  • AC erase

Here you can see the large 6 x 9 inch bass woofer that is in the rear of the boombox.




It has nice looking toggle switches and an "Enviro" switch which probably attempts to produce a fuller surround type of sound or wide sound.




The Williamsons AIE-2000 measures 19.3 x 10.6 x 5.9 inches and weighs in at just over 16 pounds.




As you can also see it has two mic inputs, a remote input and a line in. You can see the large bass speaker silhouette on the back of the boombox grill.




This particular box was sold in October of 2013 for $350.00 and had quite a number of bids so it seems to be pretty desirable amongst collectors. The unit was sold on eBay by dimbulb00 who sells quite a few boomboxes. You can check to see if he has other boomboxes for sale HERE. His YouTube video of the box is worth watching as well.
