It feels like I have read basically every thread here now, so I guess it is time to do something practical of all that reading. I am thinking of building a boombox - surprisingly enough - and I would need some help to see if what I have planned to build is a good combination or not. I also have some questions.
First of all, I planed to build the famous Boominator, but though my budget did not allowed that I thought that I maybe could "cut it in half", building a "light edition". My thought was to use two HP10W and two tweeters instead of four of each. It was still a little bit over budget unfortunately, but I would still manage. But now I saw that ljuda.se, where I was planning to order my elements, was out of stock of the element, and they expected to be in stock again in august..
So I began to search for other possibilities and this is what I found out:
I'm thinking to buy two Monacor SP-60/4 and two Monacor DT-25N that I have seen V-Bro recommend a lot.
It seems like it will suit my criteria quite good. Now, to some questions:
- I was trying to use ljudia.se's software to calculate how many litres the box should have. With two SP-60s in the same box, it says that I should have a box that is 11.09 litres big calculated with a qtc that is 0.707. I read somewhere that a qtc that is 0.707 is optimal in a middle size room and not outside. And therefore should you should write ~1.0 instead in the qtc (if I remember it correct...). But when I insert a qtc that is 1 instead of 0.707, and now it says the box should be 3.79 litres. Is that correct, or do I do myself to a laughingstock at the moment? )
- The SP-60 speakers is on 4ohm, if I understood it right, 4ohm is the best for the amp? The tweeter on the other hand is 8ohm. But according to what I have read here, it doesn't really matter. I have also realized that I need some kind of resistance between the tweeter and the amp to filter our the low frequencies. Is that correct, and what kind of resistance should I use?
- Do I have to (or is it recommended) to use a crossover (or maybe the name is frequency crossover?) to the woofer? In that case, is it easier to buy a two-way crossover so I can use it both with the woofer and the tweeter?
- Will it sound good? Will I have some bass at all?
- Will this setup suit the amp in a good way? Or can I get more bang for the buck maybe?
I am really sorry if the questions are so called "noob questions" but I have tried to find the answers in the forum before I posted, and I have probably found them, but I didn't really understand them I guess.
Thank you all in advance!
Edit: Sorry for the misleading name of the thread, "Boominator very light edition" does not really suit its contents. I accidentally pressed the Enter button before, and now I can't change the name. That's why.
No worries Erik, I fixed it for you...
