Great job explaining your foam replacement. Mine came out perfect !
I have the Boston Accoustics A 40 that I bought back in the Winter of 1986. They sounded great and were written up in various audio magazines as a very good pair in sound & price for bookshelf designs. For 13 or so years, they were used at my mom's condo when I gave them to her for her birthday in January. They didn't have a lot of playing time by her or when I came for visits. By the early 2000's, I started to use them more frequently with my large audio collection...then, one day, they sounded bad. Took the grill cover off and wahala! They had the deterioration of the foam woofer supports. It was many years till just this week in October, 2019, that I finally ordered via Amazon the "Simply Speakers" replacement foams.
I've watched a few RUclips videos on how to replace the foam parts and, none to me seemed as easy as THIS video. Now...my question to this video is how to correctly trim down the slight excess of the foam units that overhang by 4/32nd of an inch. I have a new ACTO BLADE cutter and I want to do the cutting right the first time. This project is a first for me. If it works out, I have an elderly friend who's deceased husband bought many years ago a set of Radio Shack 15" 3 way speakers and the woofers are in need of a foam job.
I would like to read someone's suggestion on my "cutting-a-bit to fit", soon.
Thanks!
@Untrepid One - I did get the Boston Acoustics A 40 series a "proper fix" last year with the repair kit from Simply Speakers web site ordering. It was not hard...just follow the instructions and take time with it. The speakers sound like "new" if my hearing, which it's far from when I bought the Boston speakers is not like way back then.
Thanks for the suggestion, though.
No need to mark the wires. They have different sizes so will only fit one way.
We added a link on our customer repair page to your video. Thanks!
I bought a set of A-70's that had been professionally refoamed for $50 shipped. I didn't realize how good of a deal I got until I heard them the first time!
Are they still doing the reforming?
I replaced the foam on a set of Epicure 10 speakers. I used both denatured alcohol and lacquer thinner to remove the glue. Lacquer thinner worked much better.
at this point I own just one pair of B.Acoustics. There getting harder to find used in good working order be sure to remove the foam from the inside enclosure.it really opens up the mides! A great speaker co that no more
Do the cones not need centralising? I was wondering how you would do so on a T830 woofer.
How did your experiment gluing both surfaces at once work out for you?
Next time use a 9v battery.... That works really well to center the cone
The voice coil should be shimmed for proper gap alignment. This will ensure that the voice coil doesn't rub in the gap after reassembly and will ensure that the speaker performs as designed. Some speakers have a larger voice coil gap and can be re-surrounded without shimming. Speakers with a small voice coil gap, like the A60, should always be shimmed for proper alignment. If in doubt, you should shim the voice coil.
No there easy to center by hand, no need for shims.
Pret-ty sure passives don't have voice coils thus no shims
@@airgliderz Like I said, "Some speakers have a larger voice coil gap and can be re-surrounded without shimming. Speakers with a small voice coil gap, like the A60, should always be shimmed for proper alignment."
@@jmb92555 The A60 is a 2 way speaker with a tweeter and a woofer. there's no passive radiator. Speakers with a small voice coil gap, like the woofer on an A60, should always be shimmed for proper alignment.
Hey, I followed your video to re-foam my Boston Acoustics HD5 speakers, actually posted the process as part of my most recent vlog. Subscribing to get more DIY tips. Thanks!
What a glue to use????
SOOO ... are you not going to use shims for correct alignment ?
What about the shims and I was hoping you hook them up to see them work.
Pret-ty sure passives don't have voice coils thus no shims
@@jmb92555 it wasn't a passive rad you idiot, passive radiators dont have magnets and tinsel leads, also its a 2 way speaker so its an active woofer and tweeter lmfaooooo
I have boston a40
Can you just buy the adhesive separately what kind of glue is it? Gorilla glue? Something you can get at a hardware store?
Glue comes with the kit most of the time
is 20 dollars for a pair of rotted ones good?
Yes
No need to mark the black lead, the two female and two male spade connectors are two different sizes. Very easy to identify.
Nope. Boston drivers lugs are the same size. I have all 6 out of my A400s right now.
Also, no need to identify the black lead, BECAUSE IT'S BLACK! lol
no need for shiming the cone already is aligned, just be gentle when installing the new foam
How would you know?
Why don't you play something and see if the voice coil will rub on the magnet.
Can i mail mine to you to fix? :) Yes seriously
haha..no testing?...voice coil probably rubbed like hell
Next time apply glue on the foam for a cleaner look....
+John Marrero I was going to suggest the same thing, you could smooth out the glue near the edges so it doesn't leak into the paper cone area or the metal surround area. Also you can apply the glue to both rings at once this way. I will do this project later today.
TERROR !!! PLEASE BAD BAD BAD VERY BAD.....
try removing the old material from the woofers edge with a craft knife on an angle..it will slice off easily
No need to do that extra zipping thing, there is a red plus sign on the woofer , you t attach the red wire to that port, you just adding extra not needed task.
Hey thanks for this opportunity, Hey I also found out that you guys could make more money if you sold your kits with a little less glue, I found that you only use a fraction of glue you give. I know other people might need more glue, but its something to think about.
Sorry, you missed a step. The dust cap has to removed and shims inserted between voice coil and pole piece for proper alignment of voice coil gap. Method shown in video will surely result in rubbing voice coil.
VERY DIRTY WORK
This was a novice replacing foam. The glue work is messy and most importantly he bought a standard generic surround versus the proper filleted Boston/Epi surround. Overall very novice.
Have you found a better pro quality video?
@@nobrizzle I mean the instructions that come with the kit tell you to put the glue on the foam itself and to shim it.... so i dont need one, its called reading the instructions, and not being a dumbass.
