Repairing BOSE 301 Series 2 1985 (1st Updated).

[Guest David]

Hello!

 

*Please if the moderator believes that this post is in the wrong place you move.

 

Recently I comment that I would repair a BOSE 301 Monitor Series 2, which I had gotten.
A friend in a restaurant had abandoned speakers for years. I asked him to sell them but he said he chose two of the four he had.
I chose those with the drivers in perfect condition, he and gave them to me.

The speakers have the corners damaged, rusty screws, smell of food and has been painted the same color as the walls .....

The idea is to leave them outside in an acceptable state, without spending much money. The sound is typically BOSE-with all the good and bad.

For me it is more a sentimental memory for the sound aspect.

In the pictures that they had put a general cleaning. The car I had to leave with the trunk open one day to remove the smell of food ....
When completed I will put more pictures.

Thanks for this wonderful forum.

Good luck with your project David.

I've seen worse systems that ended up looking OK. However, I'm not sure about the smell. Let me know how you make out with it.

I fixed up a pair of Behringer Truth biamped studio monitors that my son shipped home from SC. His packing was totally inadequate and, being about 30 lbs each, one of the cabinets was totally dismembered when it arived home. Of course, the UPS insurance was useless. Anyways, I put the system back together and reinforced all of the joints on both boxes with construction adhesive. Structurally, this worked great. However, even 6 months later, when the speakers are cranking and there's enough air moving out of the ducted port to blow out a match, the smell of construction adhesve is pretty strong. It likely permeated the acoustic insulation inside the boxes. It will probably dissipate some day, but it is an annoyance right now.

 

Good luck with your project David - keep us posted.

Try running a vacuum cleaner deep in the port to cycle fresh air through it~

Thanks for the suggestion Rabbit. I guess even if that didn't work, it would really suck!!

 

Sorry, somebody had to say it!

Hello again!

I leave you more pictures.

As it stands now could be put in the living room.

The "wood" (if you can call it that) comes back the original shine.

I need to improve some corner and remove some remnants of green paint (look pictures).
Later I will take the speakers to see inside.

The money spent between speakers and material has already reached € 10 -need more for a Hollywood blockbuster, but I'm happy .....    

When I finished I would put more pictures.

Greetings and thanks for the forum.

David, great job on the speakers.

[zumbini 6,147]

Looking good David! Certainly a big improvement over your before photos.

 

By the way, your cabinets are made from MDF (Medium Density Fiberboard).

(At least that's what we call here in the states. I think across the pond they call it engineered wood.)

It's chunks of wood bound together with adhesive, and formed into sheets under pressure.

The result is very dense which is good for absorbing vibrations. Not so good for pretty exteriors.

It's general covered with some kind of laminate to dress it up.

Exactly Zumbini, you can see in the open corners of the speakers that the material is MDF.

Here in Spain is called the same (MDF) or in spanish "Tablero de DM" (Medium density board)

 

By the way -when done- if still smelling of food, I have to put them in a plastic bag for a week with an air freshener ....

Charcoal and/or baking soda would absorb the odor better than an air freshener.  You need to remove it, not mask it.

Nice restoration, David. I had a pair of 301 SII's for 20 years, always liked their sound.

[Blues Pwr 766]

Congrats on your restoration, well done, nice finished result, enjoy...... 

[jldeni 439]

Great job David - and thanks for sharing the pics with us. Hope you get a lot of enjoyment out of your 301's.

Nice job David, they definately look better now.

Just a few ideas...I've used Febreze to get odors off of equipment, quite successfully... Also, I have filled damaged wood/MDF with Polyester Body Filler(Bondo), sanded smooth, then recovered cabinets with new vinyl. Can get it in many colors and textures. Not too expensive. Krylon Fusion spray paint also works well on speaker cabinets, clean with paint thinner first helps adhesion. Good luck with your project!

[Guest Bill]

Those came a long way, and those are the first Bose speakers I actually like the look of, the "professional" series I would guess. As far as removing funk (smells) goes, I would Fabreze the crap out of those grills, I'm talking like 2-3 times before I would expect positive results.
