[Small Advent Crossover Variation and questions]

I put in the 4uF caps and they sound great - I can't distinguish between the two speakers, even they they are slightly different vintages.

 

Thanks for the advice!

Using a 4uF capacitor instead of the original 5uF won't hurt anything. You probably won't really hear a difference. It had more to do with Advent's measurements to zero them in.

However, if you want to maintain the speaker with original values and can't find a 5uF capacitor, put a 4uF and 1uF in parallel.

Thanks for the reply -- I'm going to try it with the 4uF -- I expect my ears won't detect the difference, and I can alway redo it if so.

Found this old thread through Google -- trying to get some info on the Smaller Advents I just got.

The Smaller apparently weren't a matched set.

One (SN #214xxx) has the later yellow foam, an orange fried egg tweeter, and a crossover with 8uF and a 4uF caps - very standard

The other is earlier - (SN #184xxx - date stamp May 6 1975), and it has the same orange tweeter, but with pink fiberglass fill, and the crossover has 8uF and 5uF caps - which I have not seen referenced anywhere else. The crossover & caps are clearly original, so it isn't a matter of a mismatch by a PO.

I had only opened the first one before ordering the caps, so I have two sets of Dayton Precision 8.2uF and 4uF enroute -- rookie mistake!

Any thoughts on the 5uF cap? I guess replacing it with a 4uF to match the other speaker is not a sound move? Or would it actually make them blend better? The crossover design looks pretty similar. Should I just get a 5uF cap (a big PITA since the order is on the way...)

Open to suggestions!
