Time to build a boombox, and I have been looking on some speakers and boxdesigns for them. HP-10W seems to be the shit but is hard to get a hold of now so, the alternative is HP-10T which some seem to hate (haven't found out exactly why?). Two of the Hp-10T is one idea I have though.
The second is Monacor SP-60 which everyone seem to like and I will be going with four of them if I choose this speaker. (The same cost as for two Hp-10T)
The tweeters I'm going for, whatever bas/midrange speaker I choose, is piezos. I'm looking at Monacor MPT-001 or 005. I want something portable with volume, bass and okay sound for drunk people overall, not HI-FI quality. And I know that bass under 100Hz outdoors is hard to get without sufficient power.
I'm going to use the Amp6 Basic for this.
I have been trying out WinISD to get a boxdesign that seems to work, have mostly been playing around with the SP-60 though and then a 85Hz tuned, 12.5 liters vented design on the box for two speakers in a bi-polar design (not going for magnet to magnet) is my plan as it seems to be okay and give + 3db at around 100Hz. (Guide me here please though, I'm a noob at this).
Will be skipping the ports at first to see how the play in a closed environment, the Qtc is around 0.7 in that case.
The box for HP-10T might just be a cube, like a half Boominator with two speakers in bi-polar placement. Haven't calculated anything on this design though.
What do you think, two HP-10T's or four SP-60? I'm planing on playing in mono if I choose the HP-10 to get greater volume and stereo (with the option to go all mono to increase volume if it sounds okay) with the SP-60.
Edit: I know the relevance of dB and how much +3dB is, but outdoors with a lot of the bass being eaten up isn't this the best idea?
12L with a tuning of 65Hz might be more smoother though and not so tiring for the ears.
