Terry,
I did found that PP amps were good to drive BAD compression drivers (with ceramic magnets). The irony was that the better amps to drive the ceramic magnet were not just the PP amps but the solid state PP amps. Do not ask me why – I do not kno...

In my view the most appaling sound feature of nearly all "high end" loudspeakers is the lack of any tonal qualities. Over 90% of them sound completely artificial with no tone. All those ceramic, kevlar, magnesium, polypropylene, titanium, carbon nano...

Richard,My platter spins for about 8 min. I would replace the oil with a light turbine oil and replace the rubber o rings as well.Replace the ceramic ball with a high tolerance silicon nitride piece and flip the thrust plate and all should be wellReg...

I'm curious as to why the preference to paper cones as opposed to carbon/poly/kevlar/ceramic/.... With weight and stiffness advantages of other materials, would advancing technology not be well implemented towards drivers? Does it have to ...

Romy,I find the Veravox 5 drivers are strong contenders when searching for elevated sensitivity 5" drivers. I heard the Veravox 5X in combination with Shindo SET electronics and found it very natural-sounding. Both 5ers have ceramic magnets, how...

Hi Measet,The original platter for the RX-5000 was gun metal which I replaced with a platter with a similar platter to Wellington's weighing about 50 lbs. , the other table came from Japan with a original stainless platter made by Micro Seiki (rare)...

Today’s prices in Hi-Fi do not base upon any other principle then “whatever market bears”. The luck of objective evaluation methods and the completely un-liberated market of Hi-Fi consumers make the “market bearing” principles being completely not ap...

I have experimented with SS/SET and now DSEP for ceramic magnet horn drivers. I will agree that ceramic drivers with SETs that I have heard being suboptimal, but after a year of DSEP, at least for my use case, I am quite content. I cannot explain it ...

[quote user="Dominic"] i thought of it as soft and chalked it up to not being as strong a motor as was needed and begrudgingly accepted that perhaps 'field coil' did not mean 'powerful motor'. I'm starting to think otherwise…[/quote]

Romy,
The upper bass horn has a Ceramic driver 18sound 8M400, the MF horn has an 18sound 2060A Neodymium magnet, tweeter is Beyma Ceramic driver and supertweeter is Fostex Alnico. The Leak amps are PP deep class A, we do have a...

Klaus,
The 515-8GPH were in same scale as the 515G with slightly above 35Hz resonance frequency and 103 sensitivity - a very good candidate for 60Hz horn. The 10” throat? No bolls to go for 9”, how about 8”? I’m just kidding. The throat ...

I am certain you need at least two ceramic dalmatians on the nook / odd item stand on the right. In addition you will need to find at least one huge paining of an English noble woman, with a large nose, ridiculous hairdo and over the top gown is a mu...

[quote user="Romy the Cat"]You have no idea how loaded this question. The crossover point with the MiniMe is not a tactical question but actually the very strategic question of the entire speaker, let me to explain why. The woofers that I use are fai...

Measet,The bearing oil on the RX-5000 should be replaced with a good low viscosity turbine oil, Zoomspark works well. When opening the bearing you will notice there is a steel thrust plate that will have a dimple on it, you can flip around and use th...

hi romy!i opened the s2 some nights ago, to me it looked different, but i will check it again, maybe some reflections really fooled me. i searched your s2-guide very carefully, the one in your pic i would without doubt identify as a clear suspension....

That sure looks like an interesting configuration for a change , all right, but are those "ceramic" drivers, or what? Does anyone know?What's with all the "space age" materials these days? I mean, are people actually listening or do they just "...

somehow i missed that moment in macondo development when you introduced S3 as a low mid driver so this came as a surprise to me - what i remember is that you didn't write so favourably of S3 back in 2004 due to its ceramic magnet. but it's good t...

I too was interested to hear these new Coincident speakers but alas they were not there. There were a couple other ceramic driver speakers there to get an idea of the breed. A couple very uninteresting and a couple quite interesting. In Arthur's defe...

RomyI called the seller today and they said it is the same socket, just the size and shape of the ceramic piece is different. The mounting holes are in the same place though. The metal pin contacts are the same. He spoke highly of them as customer...

I know it is a trivial point, but I dislike the whiteness of valve sockets. Since neither teflon nor ceramic is easily painted I have mine covered in black nomex fabric. This is no good for the 6c33c, of course, as it needs all the breathing spac...

[quote user="jessie.dazzle"] For now, the amplifiers I use are a pair of Lamm M1.1s (was going to look for a pair of used ML2s, but more and more considering building a pair of Meliquaides). Using the M1.1s with a pair of V.A. Parsifal/Encore (direct...

[quote user="CO"] Ive been building and improving my own speakers the last few years and at this point i'm thinking a fully horn loaded setup ( 3 way + sub ) is the best route to take to get a speaker capable of faithfully reproducing the elect...

[quote user="Merlin"] If they are modifying conventional drive units by hand, the labour costs alone can be prohibitively expensive. The fact that they are using heavy Alnico magnets and coating the diaphrams suggests that these units do not co...

[quote user="Paul S"]I wanted to add that I have found that the effects I just mentioned occur even when the sound is EQ'd to "compensate". Setting aside the other issues raised by EQ, the notes in the EQ'd spectrum still "develop" with the upw...
