    Celestion Axi2050 Horn Driver - Holy Cow!

    I really like the Axi 2050s in SEOS30. Use them for music and films. Dont play extremely loud and don't hear the same problem as Crowe. I of course dont have his experience in testing compression driveres. I currently only have experience with Altec 299-8a ( used them for many years on Altec...

    Munich show 2023 Hifideluxe and MOC .

    I saw Fremers youtube videos on Munic 2023, and even if the different items are pretty nice and well-made, the prices are far through the roof. This is prohibiting recrutement into hifi. In the 70s and 80s, one could buy decent stuff when studying and dream realistically of being able to afford...

    Celestion Axi2050 Horn Driver - Holy Cow!

    Nice system. The axi 2050 are great CDs. I have a pair in SEOS 30 horns, using altec 828 VOT cabs for bass and a jbl2242h as a sub. Sorry about the vire mess, am still experimenting :) The setup there is miniDSP flex eight, IcePower 1200as2 on the horns and a hypex nc400 on the sub. Still have a...

    What turntables do you use? Pictures would be nice as well :-)

    Yes I bought them several years ago before they became really popular for a lot less than a 12” SME 11 or 12” Schick. First one for a Denon 103, and found it was quite good, then the std one for 2M Black ( and other MMs) and at last the one for SPU-A. Great tonearms. I initially planned to ask...

    Single-Ended Triode (SET) Amplifier Revolution of the 1990s. Did it really happen? Was it Successful?

    I must add that there where many building horns in Denmark (where I lived from '80-'91) in the late 70s early 80s as example the DIY Duelund (yes that Duelund :) ) concrete horn which where similar to Lowther acoustas. I also heard DIY Acousta horns in 1980 with Coral speakers.Great detail and...

    Single-Ended Triode (SET) Amplifier Revolution of the 1990s. Did it really happen? Was it Successful?

    Revolution or not. My inspirators where Hiraga in the 80s and later Joe Roberts and his Magazine in the 90s. Bought my first hifi system in 1975, dreamt of valves and horns through the 80s but could not affortd them (althoug i got some effective loudspeakers - Mini Onken). Got som pse2A3 amps in...

    Your All Time Favorite Preamplifiers?

    I used a passive volume pot for many years together with PSE 2A3 amps and Lowther horns. Changing my passive to a Slagle Autoformer volume vas a great upgrade and a great solution for that very revealing but bass limited system. With Altec 604 I then used a Leben RS-28CX with several different...

    Field Coils for Audio Systems

    Does not the the voice coil resistance play a part in generating current in the voice coil in the first place via the amps output voltage. Can we have pure current gain amps with no voltage gain in any stage driving speakers?

    The Mysterious Case of the Listening Window! By Jeff Day, Positive Feedback

    Altec VOT crossovers were made for example for cinema and the speakers standing behind the cinema screen. For home use, you need different crossovers. I have A5s and have original crossovers which I don't like at all. I used some 6db/octave autoformer crossovers for a period (which were fine)...
