Let's Talk EPI/Genesis

I think I have dug into most of the EPI/Genesis threads on AK in the past few weeks. I currently have M100 and 200b's as well as a pair of Advent Prodigy's that have been Humainzed (changed to Human woofs/tweets and 10uf cap). I really enjoy the sound and simplicity of these speakers. I have some other speakers in the house as well (ADS/Dahlquist) but lately really find myself enjoying the EPI's. My son in law also has some Genesis I's that I am in the middle of recapping and upgrading wiring, etc. I would love to hear some Genesis II's, but I have never seen a set local for sale, may just have to gather the parts and build them. Would also love to hear the M150's as well as see the construction of those cabinets. Anyway, would love to hear from more EPI/Genesis/Burhoe enthusiasts.

I have a set of M100's that is actually the first pair of stereo speakers I even bought. Used them for a long time as my primary speakers but then I bought a small house and they wouldnt fit the livingroom so in came the Bose accustamass 3. The EPI's went out to my workshop where they were lovingly abused for many years. Sold that place and built a bigger house and those went into storage when I found a nice set of Dynaco A25's. I then built a new shed and the EPI's where pulled from storage to find they had suffered damage due to something falling onto the front of one tearing the woofer cone. Fixed that with Elmers and I believe landscaper fabric because it seemed pretty close to texture and weight. They are now being lovingly abused in the shed and still sound quite nice. Cheers!
 
Thats awesome, as you were describing them, I thought maybe I restored your old speakers :-) When I get the set I have they where "spray" painted, I might prefer the term "tagged" with black paint, one of the woofer magnets was sitting at a 45* angle when I pulled it out of the box. I will post a pic if I can find it.
 
LOL! I nearly killed a second set of Dynaco A25's I found locally for $50.
One of the woofers was "frozen" so I thought they were melted so I thought I could cut out the voice coil and replace. Well I cut it out alright and then found out that the magnet had done just what you showed above! Damn it!! If I have removed the woofer first I would have seen that any just re-epoxy it and likely would have fixed that speaker. I did find a replacement voice coil and fixed it but way more work than was needed! Anyway...I learned a bunch!
 
Epoxying magnets is a bit tougher than you might think - the magnetic force in the gap is very strong, and unless you clamp the magnet, the pole piece will slide right over to the other side of the gap. It can be done, but it is a bit more fraught than one would wish, and the potential for mashing fingers is pretty high.
 
I still need to deal with that woofer. I played musical woofers just so I could make sure my wiring and everything was working. so I pulled the woofers out of the 200B's we have, that was a BIG MISTAKE, when my wife found out the original woofers were not in "her" speakers I had to scramble.. :-) SO they have a set of Genesis I woofers I had laying around in them now. They really are a great little speaker, though I did rotate in my ADS L9E's last night which reminds me not only how good the ADS are, but just how good the little ol M100's are. Keep in mind, this is all in a 12x12 room.

Does it need a refoam also?
It is not easy to fix it when the magnet falls off like that but it can be done, easiest is to
just buy another on ebay. Nothing to lose trying if you have the time.
 
I will buy another set for sure, just thought the learning would be fun. Finally scored a set of gold ring tweeters for my 200’s so will start the hunt for the woofers next
 
I was able to get a set of Genesis woofers when I bought a set of speakers to replace my son in law's Genesis tweeters in his Genesis I's. I think I am going to start the hunt for some Genesis II's. I love the 200's but the bass is a little boomy at times.. hoping the smaller Passive and smaller enclosure may tighten that up. Would love to hear a set of 150's as well
 
Huh, I have 150s, that I modded INTO something similar to 200s, because I thought the bass was quite a bit more realistic sounding.

It may be that the 200s just need a bit more cabinet damping material and a bit of extra weight on the PR...

Gordon.

i can play with the damping, not sure I know what to do to add weight to the PR

Adding weight to the passive radiator, is pretty simple. Even take something like some clay or similar, and try attaching it to the back side of the center of the PR diaphragm, temporarily. Try an ounce or so at first, maybe add another ounce if it seems to be going in the right direction. If it sounds better, then find something of the same weight (wood or metal), and glue it on the center back of the diaphragm...

Ok, I will get into this this weekend, thank you for the suggestion. If I can get the bass right in these they will really be a great speaker. Except that boominess I really like them.
 
I recently converted my Advent Prodigys that are rebuilt with Huw’s drivers and a 10uf cap (hence an epi 100 in a prodigy box). to a bi ampable setup. First round of listening with Adcom power, gfa-555 driving the woofers and gfa-535 driving the tweeters. I must say and it’s likely not the bi-amping, but just in general these speakers sound GREAT!!!
 
Well I finally rearranged my small listening room a little today so that I could do some A/B playing.. Using my Pioneer SX-838 for power, I have had my Humanized Advent Prodigys, ADS L9E, EPI M150's, ADS L810 (early Braun drivers), and my EPI 200B's all in the mix.. definitely so many variables when "comparing" if you will, speakers. Position, music, source, etc.. I definitely have learned alot today about the variances. All being said in the 50wpc arena, there are some surprises.. First surprise is that the L810's aren't the dominant winner. Based on everything I have read, and well, L810's values currently, etc. I would have thought they would be the clear leader of the group. I am not surprised, but some may be at how good the L9E is, clearly it doesn't have the bottom end that the 810's or 200B's have but at 50wpc in a 12x13 room they definitely have a sweet warm sound. The M150's which I believe to be original caps and wiring (I have had them opened up but didn't pull insulation, but definitely the original dental floss wires and wire caps are in there), the woofers have been poorly refoamed (well rubber anyway), have a very sweet sound, I definitely have an appreciation for the Burhoe sound. When the M150's are paired against the 200B's, they don't sound as similar as I thought they might. The 200b's really compare head to head with the L810's and in many cases in my opinion are better than the 810s, when switching from the 200 to the 810, I hear that "boxy/boominess" that I have read about many times. And unlike going from the 810's to the M150, the 200B's don't sound like the mid range was removed. At 50wpc, they can run with the 810's easy in my opinion.. I find it interesting in going from the L9E to the Advent Prodigy (with Human Drivers and caps) when I first switch it sounds like the mid range is GONE, but once I listen for a minute or two they become so natural sounding, I don't know how to explain it.. I will leave it at that for now, I am still listening, may chime in some more later.74D1F2A4-1A77-495E-A714-64C565C5E1D7.jpeg
