Guest Puma Cat Posted November 26, 2008 Report Share Posted November 26, 2008 Yes it is available.Can you tell us what equipment you're usingto drive your Advents?How are they positioned in the room?Are they Originals, New, or 5002/5012?ThanksHi, Pete.They are original Large Advents, with the Newer Advent woofer installed AFAIK (the 9.5" metal framed woofer). They were restored by Stephen Menstell, who restores New England progeny speakers and sells them on eBay. My listening area is small, as I live in a small townhouse. The Advents are being driven by a Rega Planar 3/SME III/Grado Reference Sonata into a Tube Box II phono stage which is currently connected to my Arcam AVR280, which is providing current to the Advents. When my recently purchased used NAD 1300 preamp and HK Citation 12 amp get back from repair (yes, the curse of buying old, used equipment), they will be driving the Advents. Here are some photos showing the layout and the woofer. The speakers are sitting on makeshift interim stands that raise them about 4" off the floor. The rear of the speakers are roughly 2ft from the short "walls", which are at an angle relative to the back plane of the speakers. Given the constraints of my listening area, there's very little I do with respect to changing their position. The speakers are about 4 feet apart, and I listen to them about 7-8 from the speakers. I can't move the right speaker out very much further w/o it impeding access to the stairs which lead into/out of the townhouse. Regards,Stephen.

Pete B Posted November 26, 2008 Author Report Share Posted November 26, 2008 Nice restoration and setup there. Are you running the Arcam in 2ch mode orsurround sound with additional speakers? Link to comment Share on other sites More sharing options...
Guest Puma Cat Posted November 27, 2008 Report Share Posted November 27, 2008 Nice restoration and setup there. Are you running the Arcam in 2ch mode orsurround sound with additional speakers?Hi Pete,The nice thing about the Arcam is that it will switch modes on the fly depending on the source.When I am watching Blu-Ray content on my PS3, it will automatically switch to Dolby 5.1. When I switchto a high-level analog RCA input and select that input from the remote, it will switch to 2-channel "Stereo" mode. So, when listening to music, Iusing the Arcam in 2-ch Stereo mode.

Are there jumpers in back that allow you to put EQ such as the BSCbetween the front CH pre amp and power amp?My point is that if you put it in a tape monitor loop it will EQ all the channels, if you areusing surround speakers, and they are also Advents then this would not be an issue.It is also not an issue if you are not using surround speakers. You could certainly tryit and turn off the tape monitor when in surround mode, then use it, if you like it, withyour new 2-ch pre and power amps.

I have tried running my version of the box, thru my tape monitor in-out and direct between the cd player and the receiver., both ways with little to no difference in the tone or volume . I printed a pic off the original thread (http://www.classicspeakerpages.net/IP.Board/index.php?showtopic=2692&st=100)( POST #110) that shows a big orange drop cap for each channel, are they .oo47uf? This is the circuit I used to design my box.My version of the box had 4.7k resistors (2 per channel), 4 total in the box, and .0047uf caps (2 per channel), 4 total. As an experiment I replaced the .0047s with some orange drop 223s I had laying around for guitar repairs, this did have an effect, highs were cut way back, too much for my taste. I guess at this point I'm just wondering if I built the original box correctly. Thanks for the help.Steve Link to comment Share on other sites More sharing options...

Thanks for the help.SteveHi Steve,The cap in the shunt leg to ground should be .047 uF not .0047 uF,this will make the difference. You are still welcome to try the loaner if that doesn't fix it. 6 dB might be a bit too much for a stackedpair, but you can also find the values tabulated in 1 dB steps. Try what you have and go from there. Please let us know what youthink! Link to comment Share on other sites More sharing options...

Please let us know what youthink!Pete, I tried the .047 and got little to no effect, so, according to the table I can pick up (4) .082 caps and replace the .047s, keep the 4.7k resistors and get 3db instead of 6db. Correct? I am operating under the assumption that all 4 caps have the same value and all 4 resistors have the same value to get a given value; 6db, 4 db etc. Correct?Thanks for helping a novice.Steve Link to comment Share on other sites More sharing options...

Make sure that the .047 is in the series RC shunt network toground. Then if you still do not hear it, swap inputs and outputs.It will not make much of any difference if these are backwards andthis is probably the issue.
