With the flux of time during Covid 19 there has been some pondering of matching needs to product features and benefits.
With that in mind l am interested in your impressions and thoughts on the following:
Option 1.
A simple to use stereo 2 way universal analogue active crossover with continuously adjustable crossover points from 200-1500 hertz or similar.
24 dB LR slopes, state variable with balanced/unbalanced inputs and outputs.
Designed with premium TI audiophile chips and hi quality Wima capacitors and high quality pots.
This will be an improved Ashly or other universal crossovers like the Rane.
The idea is too keep it simple for those who want premium sound quality but aren’t into taking the lid off and making fine adjustments.
It won’t cost an arm and a leg because you will deal direct with the factory.
Option 2.
A stereo 2 way analogue active crossover that can be set up for specific Jbl systems using plug in cards.
In concept like the DX1. It will also feature a sub out put with an optimal low pass filter.
The crossover frequency, slopes ect are all set precisely for your particular Jbl systems.
The design will use premium class A Jfet buffers and high headroom studio quality discrete op amps.
Available in unbalanced as this crossover is for consumer hifi fanatics. Balanced connection and circuits add cost and complexity and frankly don’t promise improvement in sound quality.
All parts are of the highest quality. This product will be endorsed by Greg Timbers.
Option 3.
A Stereo 2 way or Tri amp analogue active crossover for the audio amateurs who enjoy building project loudspeakers of their own design.
The design will feature premium class A buffers like option two but with adjustable plug in crossover cards for crossover points and slopes. Special purpose plug in cards will be made available for equalisation of low and high frequency drivers and phase alignment of low and mid frequency drivers.
It will available with unbalanced or balanced connectors to a customers requirements.
Option 3 will be sold with the Dayton Omni Loudspeaker measurement system.
I have a reasonable inventory of popular JBL small and large format compression drivers and a growing collection of horns and woofers. So I can offer users with ball park crossover set up guidance.
Why Analogue? Because it’s simple with not a lot to learn and adjust. The focus is on doing the least damage to your precious analogue source. Vinyl is well and truly back and it sounds incredible with with a pristine signal path.
I have some state of art test abs measurement equipment on order.
Just a show of hands would be useful or other ideas.
