An Update from the CTO & Head of Development Team
I'm Chia, CTO and Head of the Development Team for Frankenspiel.
In this update I will cover important information on the technical side of the FS-X, but more importantly communicate what is happening in regards to finalising for production.
Following this update, we plan to organise a live Q&A session to allow you to ask me some more technical questions.
We’ve all been working hard on the development of the FS-X and we’re just as, or if not more frustrated with these delays as you. After all it's our reputation that is on the line here.
So why the (further) delay?
Basically the FS-X represents a real step change in power and performance, not just marginal, incremental improvements. What has kept us busy for much longer than we anticipated, is ensuring its stability and reliability.
Since the latter part of last year we have been frustratingly close, but the electronic circuit boards have struggled so searching for a compromise which delivers power within capability of component parts has been our primary goal.
We are essentially fixing the performance envelope with software tuning. This is difficult because we are are working in unknown territory and we are pushing the performance envelope all the way out.
The outer boundaries of our amplification platform is currently at 25 V @ 2.8A = 70W. Remember we are using a 2800 mAh battery, not mains power to do this. As well as designing for reasonable good bass performance and without a heat sink.
Now that we've finally had the amp platform fully operational for a while, and available for intensive testing, we've seen issues with driver reliability. No driver can handle the raw power that the FS-X amp can put out. Our performance envelope is far outside what BMR drivers (or any driver for that matter) has envisaged. So we are currently governing the amp down to 20V @ 1.8A which is about 35W.
As we work on these governing/control aspects we are developing completely new techniques, many of which are patentable.
The overriding drive now is to finish mapping this performance envelope and fix the final specs by software tuning to ensure that the power and performance is matched by safe, stable, reliable long term operation.
It’s simply not worth the risk of rushing and sending out a product which sounds great out-of-the-box, but is unreliable and degrades with continuous use. If we have to recall the FS-X, it will be the end of Frankenspiel and the end of our dream.
To put it even more starkly we’re busy ensuring that the battery is safe, the electronics don't overheat and the driver doesn't disintegrate.
We hope to have this done very soon (we don’t expect it to take longer than a week), and then we will release the final production specs in an update.
We will then organise and film the demo and comparison video. And start production.
A note on performance:- the search for stability has dominated in these past few weeks, but we need to make it clear the FS-X will still be capable of delivering our ambitious max SPL goal of > 100 db whilst maintaining high-quality, undistorted sound with 50 hours battery life. This is a breakthrough in itself, unrivalled by speakers on the market today.
We are pushing the boundaries and trying to achieve something that is truly revolutionary, not just a 1 or 2 % improvement on what is currently available. We are doing something that no other designer or manufacturer has done before. This is precisely why we are experiencing speed bumps.
All the best,
Chia 'CTO & Head of the Development Team' at Frankenspiel
...You are helping to fund dreams and revolutionise markets, we thank you for your continued support.
Our next update will be no later than two weeks from now, 19th February 2015. But we do intend to hold the live Q&A session and update you with final production specs prior to that.
All the best,
The rest of the Frankenspiel Team
