Advent/1 rebuild project


Woofer-01

Here are the pictures...

The 13uf cap is not easy to find so I used Dayton Audio 6.2uf and 6.8uf 250V 1% Caps in parallel.

I opted to glue the surrounds on the front edge of the driver instead of the inside edge (factory).

I also replaced the screw nuts connectors with 5-way binding posts

Comments welcome... 

These are really nice sounding speakers

These were an estate find... Ignore the right hand cabinet (an EPI M100W The "Test Mule" for cabinet finishing solutions)

I was stoked to see the grills were in this condition. Right hand Advent logo will straighten by realigning the grill cloth stretch

Surrounds were toast, as expected

Love the Serial Number label on the foam

Original NLA crossover with no switching (13uf Cap)

This is just a test fitting of the foam surrounds prior to cleaned old glue off frame edge and repainting frame edge.

This glue takes a bit of work to get off the frame... Can't stand to see glue globs on reform jobs

Follow up...

Just recently scored my second pair of NLA /1s. You may ask why... Well they were $100 and were in fantastic shape.  I had recently been subjected to the "ADVENT STACK" bug on another forum so when these came up, I jumped on them...

New ones are on top with the lighter grills.

Speakers must be stacked so the Tweeters are in the middle with the top speaker inverted

I am here to tell you if you ever get a chance to have two pair... then this is worth trying. The sound is ...magical.

 

Music machine is in the back peeking just in the lower right of the Paper towel roll...

Pioneer SX-1010 under restoration. Wanted to make it a complete 1970ish presentation of sound... the combination was spot on.

This is so cool. I was on the very same project in August 2020. Same speakers, same crossover solution.

Mine were free. A guy posted on the Nextdoor site that he was putting them out on the curb for heavy trash if nobody claimed them, and I did, fast. He even included the surround repair kit that he had never used. What a guy.

These have the vinyl veneer, and they were a bit beat up. The grilles were hopeless, so I replaced them with something not at all original looking, but I like them. I had never done a surround repair, so it took some time to get up the nerve to start, but it worked, although I was pretty messy with the glue.

The sound is awesome, and I look forward to the livestreams of our Houston Symphony this season.

Yours look really good.

Awesome...

Not bad for the first time!

Restored...these speakers make better music than any of the news ones costing over $400.  Enjoy them!

Consider replacing the iron screw connection terminals in the back... pop out the woofer, unscrew the back old "round speaker connection", stick a Phillip's screw driver on the crossover side to hold the screw, remove the locking nut on the back, remove the old iron screw assembly (shown below)

I put these in an old parts bag and taped them to the inside of the cabinet so they stay with the speaker after I am long gone. Someday they may have an historical value to some purest

Now you have your choice of several updated gold-plated connection systems from a parts house like Parts Express

I used these... (Disclaimer: I do not work for this company or would accepted (or have accepted) any kickbacks for this referral. It was just what I used)

The new replacements just pop in the existing holes and on to the original wire terminals and fasten with the new gold plated nut (circled in picture)

Here is what they look like after the upgrade

This system accepts five different speaker connection options and provides better overall connection performance.

Here is another option...

This one I like because of the speed you can pop the wire or pin connectors in... Just push, insert, and release and you have a solid connection. These install just as quick and easy using the existing holes. (discard the gold wire tabs or use them to replace the old terminals).

NOTE: These do stick out the back of the cabinet a bit so only consider them when you are not placing a speaker of a shelf or close to a wall (which is not a good idea for best soundstage. Most larger speakers sound better when carefully placed away from a back wall about 8-14 inches and angled to the listeners)

No soldering or crimping required with either system if you use the old terminals which work just fine
