If we are talking about full range horns, then any "Top Horn Speaker" made today would have to have a bass horn to handle the bass below 100Hz, preferably a forward firing one, and one that goes down to at least 30Hz @ -3dB, or 20Hz @ -3dB would be even better. One would have to consider a...
It is perfectly possible to design and build a totally silent SET amplifier that you can put your ear to 105dB horns and hear zero noise from the drivers, as in no hiss or hum. I have been doing this commercially for over 25 years so you can hear the best from the SET topology.
Yes. I bet it does. I've never rated the newer SME tonearms with the exception of the M2-12R. Tonearms like the Schroder and Thales are significantly better than any SME IV/V and V12...
Do be aware that Quad ESLs, both original (ESL57, ESL63) and the modern ones made under Chinese ownership, are not that reliable and will require servicing and repair, if being looked at as a long term purchase. Unlike conventional box type loudspeakers including horns etc which very rarely...
You should also check out the Klipsch Heritage range of speakers (Heresy, Forte and Cornwall). Good sound plus lots of efficiency so you can use a nice simple amplifier to drive them...
No spin, just 50 years of audio experience, including 25 years manufacturing some of the best sounding audio products and working with some of the worlds top audio manufacturers. You forgot to mention the numerous preamplifiers I have made for clients using active speakers like ATC's. Back in...
In order to achieve one amplifier per driver you will need an active crossover (analogue or digital) and this would have to sit between the system preamplifier and all the power amplifiers needed for each of the drivers. The active crossover can be done using active components, as in op-amps or...
Note: The UK mains voltage is 240v, (nominally 230v +10%/-6%) so best to see if your Ref40s can be converted to 240v working. Some UK mains voltages go as high as 253 volts and above. I have measured 256 volts here which is just outside London. This will have a big impact on the operating points...
I have been involved in the manufacturing and the repair of electronics for over 40 years and I have had pretty much everything through our workshops, so I speak with experience. There are numerous posts on forums about this subject. Check out the Devialet Phantom for example. This speaker...
