I don't get how you do it!

Once I hear a speaker I want to try something new

Hello,
My younger Brother uses Ascent i's for Main and Surround with a Theater i and Descent i in his HT and the results are utterly stunning.
Every time I go to see him, I am stunned at how much bigger his Ascent's are than my Vantages. They really are lovely Speakers.

For his 2 Channel rig, he uses Focal Electra 1037 BE with Rogue M-180 Tube Monoblocks, Audio Research Preamp and Rockport Turntable.
Cheers,
JJ

Re: Personal Speaker Evolution Thread

I started in about 1965 with a small Zenith stereo phonograph player with extendable speakers. Shortly after I began reading Stereo Review and High Fidelity and discovered Gordon Holt's Stereophile, I caught the hi-fi bug at that moment. First real hi-fi speaker was the AR-4ax, then replaced with Rectilinear Mini III.

Then I heard the Magnaplaner tri-fold panel speakers and instantly became disgusted with my own system, decided rather not to listen to them anymore, vowed to have something that will give me the semblance of the transparent sound that's was etched in my mind. Bought a pair of newly hailed Stax SR Lamda electrostatic headphones and listened to them for years until I finally bought a pair of Apogee Duettas when they first came out. I was happy with them for a few years and then discovered true transparent sound of the Soundlab speakers, replaced Duettas with Soundlab Prestines and was busy rediscovering my growing record/cd collection.

I found myself occasionally yearning for the real low bass when listening to newly recorded symphonic music. Bought Legacy Focus (twin 12" woofers) and keeping Soundlabs for fear of wrongly selling them. It didn't take me too long to decide that the powerful newly bought Focus can't compared with the Soundlab's transparency and sold the Focus. Bought a pair of Dr. Hsu's first passive subwoofers (SW-10) when I found out that he designed them for his Quads. From that moment on I have been very satisfied with my sound for a long time. When Paradigm introduced the Servo 15 I decided to upgrade my subs to a single Servo 15 and settled in for a *very* extended period of time.

I recently discovered Dr. Earl Gaddes and began to implement his multi-sub method by reusing my old Hsu subwoofers and a newly bought Polk PSW-10 sub and my Servo 15 (total of 4 subs), my system is now totally *transformed* and I am extremely happy with the sound coming out of my old Soundlab and the 4 subs. But I want to be 100% satisfied and my next step is to get the Geddes Abbey 12a and rediscover the nearly 5000 cd/LP collection that I've built.

Re: Personal Speaker Evolution Thread

jheyau.....have you heard Dr Geddes speakers as of yet, and/or ordered a pair? I went to his house and listened for myself back in early April, and ordered a pair of Abbey 12a speakers for my mains and a Nathan for my center. It sounds like we strive for the same thing from our speakers. I am in the process of retooling my system and when I take delivery in mid June of the Geddes speakers that will complete the picture. I too am going with the multi sub method for LF. I am using a total of 5 right now,2 passive 550 watts each, and 3 powered subs 2 velodynes and a yamaha. The LF in my system is great right now and I haven't even done any measurements yet, have you? If so could you please post your results, and when I do begin testing I will post those results. I never would have imagined you could have a sub behind your listening position and never know it was there. I use the subs configured so for 2 ch listening 3 of the subs are operational the 2 passives and 1 powered, and for 5.1 viewing/listening all 5 subs are operational. I control the subs with a behringer dcx-2496 as Geddes recommends. Please let me know how the multi sub approach works out for you.

Re: Personal Speaker Evolution Thread

dwr, I haven't heard the Abbeys nor have I placed my order yet. I will most likely go listen to Dr. Geddes system when I pick up the Abbeys on the same day. I'm about 5 hours of drive away from Earl's home so I don't think I want to make two trips. I have read enough positive comments from different people who have bought the Geddes speakers that I feel very comfortable in buying them without a listen. How would you describe the difference in sound you heard at Earl's system from your own highly regarded Linkwitz Orion++/powerful muti subs?

I haven't done any measurements either. I must admit that I am probably the least technical guy of all the audiophiles I know. The latest round of posts from Dr. Geddes and other members in the diy Audio sound very intimidating to me. I remember Earl said somewhere that once when one has 4 or more subs, it really doesn't matter too much about their placements as long as they are not too close to each other and set their levels different. I have both downward firing little 10" passive subs behind my Soundlabs which are about 6' from the frontwall. One of them is raised 2'4" off the floor and 3' from the left sidewall. The other one is right on the floor and 3' from the right sidewall. The active forward-firing Servo 15 is raised 3' off the floor (measured to the center of the driver) and 7' from the frontwall on the right wall. The cheap little 10" active Polk is placed on the floor on the left wall about 7' from the backwall. Although I don't know if my subs are placed in their optimal spots, I'm very happy with the sound I am getting from my old and modest setup now. I have a feeling that I might go away feeling totally inadequate about the sound of my system after I've listened to Earl's system! In fact that would be a good thing because that means the Abbeys are *that* much better than what I think is satisfactory. Earl mentioned many times that the Abbeys get 90% of Summa's performance at less than 1/2 of cost. Now that is one super deal that all music lovers should consider!

Re: Personal Speaker Evolution Thread

jheyau, I listened to the sumas at Dr Geddes home and did not get a chance to hear the Abbeys. The Geddes speakers have every bit of clarity of the Orions but the Gedders speakers will play at way higher volumes than the Orions and sound much better doing it. The Orions excelled in soundstage as in an orchestra or big band recording you can feel the placement of each instrument that was their strong suit. But in a nutshell his system was far and away the best "home based" system I have ever heard. As for the measurements I'll give you an honest run for your money on the least technical audiophile thing, and yes the threads on the diy site are intimidating but Dr Geddes offered to show me how it is done which is the nice thing about living only 20 miles from him. As for my subs I am just like you I love the sound I am getting right now with the def tech speakers I have now, when I sold the Orions I kept the 2 Thor subs and have one of them firing upward in the left corner behind my left front speaker, the other Thor is built into a coat closet and fires across the room behind my listening position by about 6ft and is about 5ft off the floor level. I have 1 10" velodyne powered sub firing out into the room on the right side behind and inside the right front speaker. Those 3 subs are used for 2 channel listening and are controlled by a behringer 2496 and powered by a behringer EP 4000 in the room behind my listening room thus eliminating the concern of fan noise in that amp. The other 2 subs are connected to my processor and are used for lfe when listening/viewing 5.1. and when all 5 subs get going on some of the new blu-ray formats the sound is incredible (I cant wait to get the Abbeys in the mix) It all works nice with the cj pv-14l preamp that I just got as it has a great HT bypass on it allowing that to send the signal to the 3 subs while the surround processor sends the signal to the lfe subs. The lfe subs are another velodyne and a yamaha both 10" powered low cost subs. You can take it from me you should have no problem purchasing the Abbeys without a listen you WILL NOT be disappointed.

Well, about ten years ago, when I was five, I remember looking under the desk of our Windows 98 computer and seeing a white box with something (an approximately 3" subwoofer driver), which I had no idea what it was. I noticed it also had a hole in it (the port). I asked my mom what it was, and I said that it was connected to the speakers, and she had no clue. Her best guess was an oversized adapter.

Today I know that it was the subwoofer in a 2.1 system. I don't know when we sold it, but it's long gone. My grandpa (R.I.P) had a surround sound system that comprised of a very old receiver, a record player, I don't think it had a subwoofer, but it had two front speakers and two back speakers (no center). They were all the same size, and they were around two feet tall, maybe 9 inches wide and about 7 inches deep. They were fake hardwood, with a black grill. The system suddenly stopped working one day and it was sold many years ago (about, maybe, seven years ago). I don't know the brand. I don't know what the drivers looked like, and I probably would have been able to fix it if I knew as much about speakers as I do today, back then. All I remember about what they sounded like is that they were loud (and when I was little, loud wasn't loud by any means... my hearing was very sensitive, although it's normal now).

Not until I was about 12 did I really get into speakers. On my 13th birthday (I got a Cyber Acoustics CA-3094 for my birthday (this system seems to have been wiped off the internet... the Cyber Acoustics website is also very glitchy). It has two 2.5" neodymium tweeters (VERY loud for 1 watt) and a 12 watt subwoofer (distorts at half volume, it can't keep up with the tweeters).

On the last day of February of '08 (29 days after my birthday), the local thrift store was closing to be replaced by an overpriced (though highly organized) thrift-store-plaza, with the speakers mostly behind the cash register. I got two Fisher tower speakers, each with a 9" subwoofer, a 4" tweeter, and a (possibly non-functioning) 2.5" super-tweeter. For $15, they also came with a JVC RX-307 reciever with 45 wpc, stable between 8 and 16 ohms. They were essentially the radio for the thrift store since 1980, when they were built, and have gone through two receivers (the JVC is the second one, I believe the first one fried). Their model is unknown, and their wattage is whatever it takes to get sound out of them. Very little is known about them, but the pair I have has history. There was also a third one, but it's surrounds were gone on the sub. But I was stoked when I first got them. I using them facing toward each other into a sort of bandpass configuration for use as a subwoofer. But when I get a surround receiver, I'll put them back to their original position as front speakers.

In spring of '09, I got two Advent subwoofers for free (you might remember one of them and it's twin from my pathetic "Pushes Air But No Sound" thread... they were free because they had badly deteriorated foam surrounds, still awaiting new ones), and a Yamaha bookshelf speaker and a JVC bookshelf speaker for $1 each. The JVC had a dent in the top (easily fixed with scotch tape), and the Yamaha was fine.

In August of '09, I bought two 12" VR3 subwoofers (I wish I knew their T/S parameters) for $20 a piece. I bought them to fill holes in a box for two 12's that my neighbor had lying in their front yard and gave it to me : ). I ported the box to somewhere between 28 Hz and 32 Hz.

So, that's basically the history of the speakers I've owned : ).

Re: Personal Speaker Evolution Thread

JoeESP9, our journeys are indeed very similar! I started out with a Dynaco Stereo 35 tube poweramp and a PAS 3X preamp, AR turntable with Shure V-15 Type II. A stereo AR integrated amp later replaced the Dynacos. Next came the PS Aduio 200c poweramp and Superphone Dual Mono preamp. VPI HW-19 mk II with Grado Signature arm and Talisman Alchemist IIIs cartridge. Upgraded the little Superphone preamp to the Aduio Research SP-9. Met John Iverson and bought his famed Robertson EK-1 strained gauge cartridge/preamp and four of his Electron Kinetic 400 mono amps when I had the Apogees. Alas! All that were in my much younger days and I'm now much, much more conservative and had been thinking about hi-fi in a very different perspective for nearly 20 years now!
