Anyone familiar with these, and how they are used to measure freq response of speakers ? I am about to get into this.
Once I have the mic, I figure I got a Wavetek 111 which is good enough for now. I thought about square waves and wil give that a try but do not have g reat hopes for anything just yet, but I am after something else.
Speakers. I am about to put some together and I am looking for something mo re than the average. In fact later, if my pardner can figure out a process for it, we might be in a brand new ESL tweeter business. Either direct coul led or using a differewnt kind of amp. Long story that isn't long enough ye t anyway. Fuck all that for now.
Regular dynamic tweeters and whatever, I wil have to buy them off the shelf though I do intend to do alot of product testing. Well this is part of it.
When I take a calibrated mic and put a speaker to it, when I have the scope on the actual generator outpur, the second trace (from the moc) should mov e. I should be able to calibrate something by measuring that change in phas e and correlating it with the distance.
Part of what I am doing other than screwing arond and learning something, i s getting drivers for speakers I want to build. I am going to order a bunch of them, all differnt, from MCM. If I can do like Bose and compensate, we will be fine.
Oh. by the way, I intend to use (eventually) a separate amp for each speake r. THAT will allow aloty more leeway int he crossover, and control ovewr ph ase.
That is actusally later though, I want to get the mic setup sooner than tha t. I need minimal phase shift and pretty flat response. If not, I need it p lotted. Anyone know where is the best place ot get these things ? Iknkw the re are a bunch of them and each and every one of them is the best there's e ver been, if you believe their websites.
So, does anyone deal with this stuff ?
