sundownz Posted September 12, 2008 Report Share Posted September 12, 2008 (edited) Now you can do just about anything with it! A little SAX-100.4 history: SAX-100.4 -- Original model SAX-100.4B -- Updated crossover ranges SAX-100.4C -- Upgraded from 50-amp to 70-amp power supply transistors SAX-100.4D -- This is the newest model ----- The following functionality will be had with the crossovers: ALL CHANNELS: Subsonic @ 10 Hz - 500 Hz (always on, can be used as the HPF for a band-pass setup in conjunction with the LPF) HPF @ 50 Hz - 500 Hz w/ x10 button (selectable 12dB / 24dB slope) LPF @ 50 Hz - 500 Hz w/ x10 button (selectable 12dB / 24dB slope) ----- So, what will you be able to do with the new model that you couldn't do before ? 1) You can bridge the amp and actively band-pass a midrange / midbass thanks to x10 functionality on both HPF and LPF on both sets of channels. 2) You can cross-over tweeters much lower with the 24 dB slopes. I have had several requests to implement this from people wanting to use planar tweeters as well, as these require steeper slopes. 3) You can experiment with overlap with the selectable slopes. 4) Most importantly for reliability and consistency... the small sub-cards that hold the crossovers will be re-tooled as double sided boards instead of single-sided. Almost all problems with previous SAX-100.4s were the result of solder problems on the single sided crossover PCB - as uncommon as these problems were we took care of the source! All of these changes will result in a bit longer amp to fit the new crossover boards (about 1.5" longer), but will be worth it for the SQ enthusiasts who will appreciate this type of functionality. ----- Special pre-order price until they arrive - current ETA is 8-10 weeks or so from the date of this posting - $325 shipped in the continental 48-states!.

Forevrbumpn Posted September 12, 2008 Report Share Posted September 12, 2008 very sweet - cant wait to get my hands on one myself I have a ritual called "terminator". I crouch in the shower in the "naked terminator" pose. With eyes closed I crouch for a minute and visualize either Arnie or the guy from the 2nd movie. I then start to hum the T2 theme. Slowly I rise to a standing position and open my eyes. It helps me get through my day. The only problem is if the shower curtain sticks to my terminator leg. It sorta ruins the fantasy.

sundownz Posted October 17, 2008 Author Report Share Posted October 17, 2008 (edited) Delivery time will be the same either way. There will be no power difference. We upgraded the power supply in the C revision, but this was more for long-term reliability* than anything as power output was, at best, marginally increased - I expect people to be using these years from now The difference for the D revision is the MASSIVE crossover update. * - There were no problems with amps with the 50-amp FETs, but I am a fan of over-building things.
