    Took a stab at testing and modifying my BIC DV62si Bookshelf Speakers...

    Hi folks, Please just "tell it to me straight" on areas I could improve on the testing process I define in my video below. Please do keep in mind I really didn't want to remove these speakers and do a "formal" near field test. I tried to keep the before and after as close to apples-to-apples as...

    Bass Port Length and Shape for a JBL 2213H DIY Project

    Hello friends, A while ago I bought an immaculate pair of JBL 2213H for a very fair price. I have always heard that these woofers produce a very clean and deep bass in large enclosures. So I decided to build a pair of speaker out of them. I got a pair of Morel TSCM 634 midrange drivers and a...

    Need help w/ in-line attenuator values

    I have an issue with pre-amp and EQ noise on a couple setups and thought in-line RCA attenuators would be the solution to try. I'm building some cables and thought DIY'ing my own or building them into the interconnect cables would be the perfect solution. I figured either -6db or -10db might be...

    Studiomaster Mixdown Classic 8 Console Problem

    Hi! I've been working on a Studiomaster Mixdown Classic 8. I opened it up to make sure the levels were selected properly (i.e. balanced +4 dBu). In order to open the console, you have to take out the entire board, not by channel strip. In doing this, I accidentally pulled some multipins in the...
