My "new" BA A-40's

My 7 year old Son has been a great sport, running to thrift stores and helping me pick up "scores". He takes interest in my hobbies and likes to listen to music. I thought it was time to replace his bookshelf unit with something better. I found a Marantz 1030 and a Denon CD-changer but was looking for speakers. After fixing up my Mothers A-60's this Fall, and eager to hear more of the BA sound, an AK member surprised me by giving me a set of A-40's. Typical story, surrounds were shot, a tweeter was dead, vinyl veneer was torn, grills were torn, needed a recap, etc. I'm generally all-thumbs when it comes to restoration but I was encouraged to make this a project. I dove head in and did the following:

1) Stripped all vinyl veneer with a sharp chisel and some pliers. Filled all holes with wood putty and sanded smooth. Being this was my first time, I did my best to rebuild smashed corners but the results weren't perfect.
2) Replaced a busted tweeter.
3) Refoamed the surrounds (Rick Cobb was very helpful). I should have probably replaced the foam rings/decorations (whatever they're called) but I didn't feel like dumping more money into this project
4) Replaced all screws (every one was rusty and gross). Neither Ace nor Menards had black wood screws so I had to make do with silver. Doesn't affect the sound.
5) Unsoldered the old caps and replaced with Dayton 10%
6) Picked up some new (used) grills
7) Replaced all the veneer with real Walnut. Oiled twice (first day) with Watco, medium walnut and another time a week later. Once dry to the touch I applied two coats of Feed-N-Wax.

Before I get to the pics, I'd like to thank the following:

1) bryana - Bryan gave me these speakers and provided guidance/advice. Thanks for all the help Bryan!
2) kymers - Mailed me a free replacement tweeter!
3) gladiator335 - Sold me the replacement grills at a very reasonable price AND he packed like these were traveling to the moon.
4) 62sunbeam - Sold me a really nice piece of walnut veneer.
5) MikeCh - provided the tutorial on how to apply the veneer. I opted to use the wood glue for the front pieces rather than contact cement, but most every other step was the same.

Here's a quick pic of the veneer before the stain (apologies for the bluriness):

Here's the final product:

I goofed a few edges, made a few chips, etc., but I like the real wood grain much better than the stock vinyl. Perhaps if I'd taken my time a bit more I'd have made less mistakes (and cut my fingers less!) but I think these turned out great for a first project. I pointed out the flaws to my Son and he said "It doesn't matter what they look like, only what they sound like." Sage advice from a 7 year old. He still doesn't know these are his and, hopefully, I'll be able to surprise him with them tomorrow.

Awesome!

I have two HT setups- one room uses Paradigm Titans and Atoms, the other uses Boston Acoustics VR series, Micros, and A-40s.

The BA system gets the most use.


And excellent job on your first effort- they look really good!
 
Excellent work! BA really did make some nice sounding speakers (listening to my A150's right now actually). The real wood veneer is a really nice touch.
 
Great project!! I didn't realize I was such a BA fan until I hooked my A150's to my Sansui receivers, especially my newly restored 2000X-HOLY FREAKIN CRAP!!!! They are indeed some tasty sounding speakers.
 
Did you use heat when stripping the original vinyl? I am debating doing my A-400's. Theres alot more surface to strip on these, so I am curious if its too labor intensive.
 
Those look awesome!

Soundesign, the A400's should be a snap. Just three thin surfaces to cover. Remove the vinyl by heating with a heat gun. It will peel right off. Then sand off the old glue with 150 grit sandpaper and an orbital sander.

No heat, just a wood chisel. I opted for the $10 chisel over the $8 model but I couldn't tell you the brand (Stanley maybe?). Just go slow, run it smooth and parallel and try not to dig in. It actually worked surprisingly well. Once you get a piece to start lifting you can grab with the pliers and rip off huge sections. YMMV. I probably broke the cardinal rule of DIY but I just sat down with some tunes, a couple of Sierra Nevadas and went to town (I recommend a CD over LP since you won't want to have to get up to flip the record. :D).
 
Nice work. Something you can both be proud of and enjoy. I bet that marantz/boston combo is a good one. Definitely a five banana job...

Your 7 year old son has Marantz and Denon equipment in his room? My jealousy is beyond measure. Anyway, the A-40's I mentioned in my other thread are Series IIs, made in 1987 according to the stickers on the woofers. Also, th etweeters are the rectangular plate in a recessed relief in the front of the cabinet. Since the woofers in mine are good electronically speaking, I'll buy one of those 25 dollar refoam kits on Ebay specifically for this model. If the speakers turn out not to work there's people there who sell recreated woofers for 40 bucks apiece. Hope it doesn't come to that though.

Those are awesome!!! I have found many speakers I've liked but couldn't keep them due to the vinyl veneer. I hate vinyl veneer with a sincere passion. This is a skill I need to take the time to learn. Looks like you did a great job.

What other components is your boy's system made up of? Also, what does he listen to?

I hope I can be a great dad like you someday.
 
If I can reveneer, anyone can. They're not perfect, but they were my first project. Still much better than the peeling vinyl that was on them.

It's a pretty simple setup of Marantz 1030, Onkyo CD player (don't remember the model #) and BA A-40's. Sounds pretty good in his room. He likes a lot of what I like (The Who, Beatles, etc.).

Thanks for all the compliments.
 
Again, envy of your son is off the scales, grrrrr. Unfortunately even the better thrift stores of Modesto California are rather pathetic when it comes to HI-FI "scores." gotta start going out of town.
