Hi everybody🙂
Just bought a pair of advent loudspeaker and a kenwood kr5400 for 10 bucks. it is still in very very good condition with instructions paste on the back of the speaker.I believe it was built in the 70's. now my question is, do I need to uprade all the caps and inductors ?or is this bad boy really sings like a hifi sound?
Thanks

Caps maybe but only if they are electrolytics and even then, without measuring the caps for changes in capacitance and ESR value it's a "who knows" situation. I'd leave the inductors alone. I'd be more concerned with the condition of the woofer foam surround. They tend to rot and get soft and crumble.
I check the woofer foam and still intact. I don't know if the previous rich owner replace it.I will check the caps.
Looks intact is nice but not likely if original. Give it a gentle poke with say a pencil eraser and see if it survives.
there is no info of the model except instruction paper on the back. the port terminal is like an old brass nut thing and the color of its tweeter is red with a plate on the back. this speaker is heavy.
msj965, you're going to drive the incredibly talented and experienced help here at diyaudio crazy unless you work harder at this. 😀
There were several versions of the Advent speaker: Speakers Produced
Now come on. We are not psychic. Photos, crossovers, stuff like that. 😎
It's a nice design IMO.

If you're lucky, you have the large Advent. By the generosity of one of the members in this thread, I was able to put a set together recently and I must say, I was very pleasantly surprised. Those who like the sound, like it a lot and I have just understood why. If the sound is pleasing then why bother recapping at this point? I didn't with mine yet as they do not seem to need it.
It's funny how you revisit the classics. And the Large Advent was one by all accounts.
Loudspeakers: When is Good Enough, Enough? Part 1 | Audioholics
It's the smooth 3" cloth dome tweeter that makes it apparently. The 10" Bass runs on a single coil. The tweeter gets a 2nd order and a low 1800Hz crossover. I can see similarities to the Dynaco A25. My own speaker (on the right) is not a million miles away either. 🙂
BTW, the various Advent filters are available if you google Advent Crossover.

What, this Fried Egg tweeter? I can only go by what I read...🙂
But I feel encouraged if it is paper. 😎

At this point in my Advent-ure (doh!) I'm thinking the tweeter needs help at the bottom. I've doped the woofer cone and braced/damped the basket, mandatory in my mechanic's opinion since stamped steel baskets are a mess at best, and I still hear hash from the tweeter. C'mon Steve get busy. Something like SpeakerDave did with the AR4x. We gotta beat that A 25 in every way, not just bass.
Looks like you have an older tweeter with the New Advent woofer, sans masonite. Oddly Dahlquist stayed with the masonite ring version in the DQ-20. Some of you New Englanders can sort these details for us I hope

What crossover and drivers have you got, Phivates? We need schematic and pictures!
I have to go with the natural 3.5 kHz rolloff of my 8" woofer here. But I agree with your comment about pressed steel baskets. Mine rings like crazy on a second order, so I'm thinking of going back to first order bass.
The Advent tweeter seems to have a well thought out 1800Hz crossover, but you can get it quite steep with 6R in front and matching (6.8uF?) capacitors on a third order.
I'd have to think about it. But yes, I think we could do something to take that 1800Hz bump down. Tweeter hash is a bit vague, what do you mean?

Quote from Steve's link:
"Henry had custom designed a cloth dome tweeter which had a 1" dome in its center but with a huge 1" cloth annulus surrounding (and part of) the dome. So to get down to 1800 Hz what the audio pioneer had designed was a 3" cloth-dome tweeter!"
I have the typical Fried Egg. The only model I have ever seen. The dome measures 3/4" and the whole egg is a c-hair over 2" It appears to be made of treated paper. I do not see a weave indicating cloth. I'll go get my magnifying glass. 😉
Hey Fred, There's your woofers 😀

Hold the presses:
When I add light and magnification I am seeing what looks like orientation to the strands indicating a weave. Five seconds later my brain tells me no, that is stippling from the coating of the paper indicating a spray, another five seconds and it's back to a weave.
Jury is out, but I will guess paper as I don't believe they had machines that could weave so finely back then and no fabric tweeter has been that hard to detect.
