Thought I would update the blog a little, been really busy at work and some side projects to keep the hobby funds active. Had some time a few days ago to measure the Little Red Book Shelf speakers, and cobble together a very basic crossover.
I am pretty impressed with a little basic crossover, this little Sb Acoustics SB15NBAC30-8 woofer plays damn low and sounds amazing in this ported enclosure.
Stay tunes, I hope to update the crossover with better structure & some better measurements before and after.
Been a while sorry guys ! Been busy working on Nelson Pass F5 Amplifiers & other Audio related things.
Thought I would post some pics of the progress on my little Red bookshelf speakers ! I did a quick inside the house Measurement the other day and “DAMN” for no crossover or any filter they are pretty smooth. ! ( will post more on that later )
For now a few photos of how they look so far ! I’m very happy with the look’s and color !
Today’s 2 Project’s Finish soldering on all the SMD Melf resistors for my Stereo All in one SSR board and do some testing. & THEN work on my Aleph Mini Class A project using 2 MeanWell SMPS powersupplies ! I have been working on this for a few weeks now and FINALY got the noise removed on the PSU’s so now I have clean ripple free 25V dc rails VERY excited because now I can work on the next stage of this project !!
Well, looks like all my hard work that I have put into this project has lead me to ordering Revision 2.0 ! Will be ordering 20 boards to populate a few and test then give a few away for others to use !
Once the new boards arrive & I have a few built, I will do another video and post it on my youtube channel.
YEP ! For Christmas present I bought my lab a new tool ! Almost every year I try to buy a new piece of equipment, slowly building up my equipment pile for the bench. ! Last year was my JBC Soldering Station !
This year we got a new QA401 Audio Analyzer from QuantAsylum ! I have been reading lots about what it can do, not sure how to use this device fully yet BUT that’s the best part, learn and have fun !
Been working on my SSr project over the holidays and when I had downtime at work. I’d have to say 40% just looking at the screen figuring out how to make the board flow nice, look nice, and build nice.
I’m pretty happy with Revision 2.0, it allows to be mounted to a pair of binding posts & also be mounted off board ( oh look I need to add mounting holes ) BUT wait, there is a reason for this, Revision DUAl 1.0 is going to come out soon so, we can wait for that.
Going to order 10 boards soon, then test these, if all goes well, I’ll order more boards and possibly sell kits as blank boards OR fully populated.
