This is a very good characteristic for drivers intended to be used in Front Loaded Horns because it will compensate for the natural low pass filter of such horns.

This is because the output of the driver will rise but lower frequencies will be tamed down by an increased impedance in that region. If we increase the electro-mechanical coupling factor BL, we will notice a rising response characteristic with frequency. Since changing the cone mass would mean altering the timbre of the driver the only option is to change motor strength. Output in this region is influenced primarily by mass of moving assembly (cone, voice coil, surround, spider, dustcap etc) and the strength of the motor. However, in this horn, the midrange above 400Hz is not very detailed and asked if somehow a field coil motor can spark some life in that band. Someone has a pair of JBL 2220H which he loves and uses them in a Front Loaded Horn. It will never demagnetize and it can offer other advantages such as adjusting the motor force for specific applications. In these cases converting the motor to a field coil motor can be a very sensible solution. Revitalizing these magnets can be very hard, it is for sure not something a DIY-er can do. This is true especially with Alnico magnets since they are prone to demagnetization. All rights reserved.There are many vintage drivers that posses a great timbre, used in many legendary speakers but after many years their motor is demagnetized to a point that they lost their output and the impact on midrange and high frequencies.

In the Symposium/Immotive/Eben room they were using direct master tapes softy copies from Steve Hoffman. In fact the entire signal path is kept short and capacitors are fully specified as well. The hand-wound transformers are optimized and simplified for short signal path.

The woofer is within its own internal enclosure, includes a massive 350 watt amplifier, and special computer software calle R-DES (Rocket Digital Equalization System) for optimizing the subwoofer to the room's acoustics.Ĭoncert Fidelity's 6B64 monoblock tube amplifier ($28,000) naturally uses four 6B46 in parallel push-pull for output tube (producing 60 watts) and 6SN7 for driver and gain stage. A Vifa XT-Series ruing radiator tweeter is mated with 5.25-inch midrange drivers and a side-firing 8-inch mass-loaded woofer. Rocket had their RS1000 ($2,700) large floorstanding loudspeakers, said to be their 'next generation' for both stereo and multi-channel systems. Meitner Design DAC8 Mk IV for digital to analog conversion. Source tapes were played back using a Genex GX9048 48-channel PCM/DSD recorder. This system was wired throughout with Cardas.
Here at the Rocky Mountain Audio Fest was a DSD multi-channel demonstration with Avalon monitors, Rowland's 501 (500 watt monoblocks) power amplifiers for front and 201 The lower unit is a folded 60Hz exponential design. This is the said to be the first all field coil compression driver system.

Just be the mac daddy with a briefcase filled with Benjamins, you dig baby?Īre you feeling randy baby, maybe a bit horny? Yeah baby yeah! The Cogent model Chiaroscuro two-way unit (no price set) employs the Cogent DS-1428 midrange/tweeter and DS-1448 lower frequency driver.
It's super big, it be super bad, we be talkin' 'bout Boulder and the 2010 Isolated Preamplifier ($39,000) and 2020 Advanced D/A Converter ($37,000). Both are great reads and highly recommended. Now in its Third Edition, Robert Harley's The Complete Guide To High-End Audio and Wish 95dB sensitivity and extending to 40kHz, it looked quite tasty. Madisound had a vast amount of raw drivers at the show including the Fountek JP3.0 ($81) 3-inch ribbon tweeter.
