Recommended Posts

I have finally completed restoring the Large Advent Collection including

the following models listed below, and pictured here:

And here for the 5012/O:

All speakers were restored with 1% polypropylene caps with resistors added

to approximate the original ESR. Re-foamed with the correct foam. T&S

parameters tested both in free air and in system. All XO components tested

for value and DC resistance. Tweeters T&S parameters tested. All non gas

tight connections tested for DC resistance (<.005R) and treated with DeOxit.

Please note that I have used 1% caps because the original caps often

measured better than 5% and I did not want to use inferior value caps,

and also did not want to have to hand select each one. All old components

that were reused were tested for value. New components were also tested

as a QC check simply to verify the correct value. All of these speakers are

otherwise completely stock with original fiberglass stuffing in the OLA and

5012/O, and foam stuffing in the NLA.

1. Original Large Advents (OLA) from 1972 owned by my family since new.

One woofer replaced.

2. New Large Advents restored as above. Tweeters replaced due to what

was believed to be ferro-fluid issues. New linen grille cloth.

3. Jensen 5012/O the /O indicates real oak veneer cabinets. All original

drivers.

I've given all of these speakers a listening check and they are free of any

strange noises or distortions, and are well balanced side to side.

I continue to be highly impressed by the OLA (with 4dB of BSC) where they

compete and in fact beat many modern designs. They are set up in my

listening room in case anyone from Stereophile or Affordable Audio would

like to hear them and perhaps review any of them.

Might make an interesting article on how to build a budget system with main

speakers costing less than $100. These would work well for HT without a sub,

and even better with a pair of budget subs such as the HSUs.

Nice, Pete!

My first "brand new" purchase of now "classic" NE speakers were OLA's, way back when. I would love to hear your BSC application sometime.

We are not that far from each other. A road trip is not out of the question. :)

You're welcome to visit anytime Roy, I've always enjoyed our discussions.

I have an A/B switch with line level volume matching in case you or anyone

is interested in comparisons.

It is not a complete collection, just what I stumbled across in my search to cover

the design of most of the Large Advents.

I should probably add the Anniversary Edition also for kicks.
