  1. Pair of NLA's from 1978 for sale. New surrounds and recapped. $100. Original owner, never abused. Cabinets solid but scratched. Located in central Connecticut. Can be auditioned here. I can deliver anywhere in western CT or bring to the Winter Frankenfest if anyone has a serious interest. Full disclosure: new surrounds are attached to the Front of the cone per the directions I had a the time. I also have a pair of OLA's that I would be willing to sell for $125 instead (with correct placement of the surround), price is higher because I like these a tad more. Also has new caps. Only selling ONE pair. Having trouble uploading pictures. Will post them later.

    All Advent questions answered

    In order: Need to clean? No, not strictly, but it doesn't hurt to hit them with Deoxit. If you mean where the wires from your Sansui are attached; masonite originals were hot glued on so you can re-glue them. Metal originals were held by staples and glue, re-glueing should suffice but you do want a tight seal. The grill covers may have been yellowish to begin with. They seem to be some type of burlap and the shade did vary over the years. Search the forums and you'll find discussions on replacing the material, I've yet to see anything about cleaning it. Lots of threads on Advents more current than this one. Try http://www.classicspeakerpages.net/IP.Board/index.php?/profile/180451-rickb/

    Opinions on Double Advent Rebuild Please

    I believe there is a technical/theoretical reason behind Pete's recommendation to not just add series resistors. Pete knows a lot more about this stuff than me. My point being there are some speaker 'selector' boxes out there that claim you can run multiple pairs of speakers with no impedance problem but for the most part they just add series resistors inside a black box. Just beware of these items. (Anything more sophisticated than that quickly gets expensive.) My (limited) understanding is while this may protect the amp it is not good for sound. I've run stacked Advents with an Adcom 535 which I believe is 60 w/c without distortion, but it was just too much speaker for the medium sized room they were in so I never really pushed the system. 535's can be found for under $150 but newer models, anything with a suffix after the 535, go for more.

    Opinions on Double Advent Rebuild Please

    As noted before, Pete B has a wealth of information on the Large Advent both new and old. Some seems to be easier to find in this forum, some in AudioKarma. Now my two cents worth: From what I've seen the original concept of stacking the Advents was originally for the OLA's with speculation that the distance between the woofers was significant. Anyone else read or heard this? The woofer placement on the NLA and OLA are different, with woofers on the OLA being closer to the bottom of the cabinet. I believe Pete's opinion is the NLA and OLA tweeters are not interchangeable( unlike the woofers), you need to match the crossovers for the tweeters. The inductors for the woofers are also different. My experience with stacked Advents and a 5dB BSC proved to overaccentuate the bass. If you do a BSC you might want to consider either making a few different values or going with a variable one as was done by one AKer. There is also the question of whether the Advent is a true 8 ohm speaker, running two on one channel can cause problems if the amp isn't up to it. As I said, my two cents worth. A bit from experience, most from reading these forums for the last two years and some other searches into the Advents. Frank, your picture above is awesome.

    Pete, are you going to post this to AK? I looked there but couldn't find anything.

    Woofer coil bypassed in NLA

    Does anyone know why the woofer coil is bypassed in the extended setting on the NLA? Also, what are the connections in the three way switch?

    I'll be there if I can make it. Wanted to go to the October event but missing a family event has a low WAF. I'd like to see and hear what others find worthwhile. My systems are based around refurbished Large Advents (with Pete's BSC) and I want to hear something else for comparison. Plus many of you guys seem to know a lot more than I do.

    Woofer coil bypassed in NLA

    But wouldn't it allow more overlap between the woofer and tweeter, and wouldn't that muddy the sound some?
  10. My bad. I didn't pay attention that every one here was referring to the OLA. It's bypassed in the NLA.

    EPI 100V with Cambridge Soundworks woofers?

    I cannot get the images of your woofers. If they look like the images I've attached the answer would probabley be no. This speaker is from a Cambridge Soundworks Ensemble "Subwoofer", which had a low pass filter at about 130hz. Unlikely it could reach to the 1800 hz the EPI woofer was designed for. The woofer from the Model 6 might work but probably would not have the same roll off characteristics as the EPI woofer. JKent's reference to Huw Powell is spot on.
  12. Does anyone know why on the Large Advents the extended setting bypasses the woofer inductor? Pete B.? Just curious about this.

    OLA ADVENT WOOFERS WANTED???

    What is the cutout size? I don't have anything in hand but I might soon.

    NLA recap... resistors too?

    I originally bought my NLA's with a 22wpc Yamaha receiver. When the Yamaha was replaced with a 75wpc the improvement was tremendous.

    Cabinets for 5012

    I think a pair of large advents may have the same basic cabinet. They are defiantly more common. I'm thinking of rebuilding a pair of large Advents as 5012's. You would need to build new crossovers as the LA's use a different tweeter (though I think very similar woofer) than the 5002/5012's. A reverse engineered schematic for the 5002/5012's is listed elsewhere in this forum.
