Er der nogle der kan hjælpe med de eksakte kabinet mål for Boominator mini med Monacor SP60/8? Har selv fundet denne. http://s478.photobucket.com/user/Shortrope/media-full//BoominatorMINIV2Dimensions.jpg.html Men er ikke klar over om den er forøget med de ca 3 procent. Taget fra http://www.diyaudio.com/forums/class-d/104402-boominator-another-stab-ultimate-party-machine-482.html#post3870292 "There are a few things. Your own arguments made me recheck my data and it turns out the T/S data I had for an SP60/8 was a tiny bit off so the speaker compartment volume has to be increased by about 3%. Also because I forgot to incorporate the volume of the filter components which is quite embarrassing. Well, actually, I didn't forget the volume of the parts, just that I moved the placement of them from the electronics compartment to the speaker compartments. At the same time I have researched data from wood suppliers and it turns out that "6mm plywood" actually average 6.5mm from most suppliers so the cabinet either has to be made 1.5mm larger in general, or substitute the double fronts with normal 12mm plywood making it easier to assemble in general. The 0.5mm extra does have many implications though, so it'll have to be reworked more or less from scratch. Since this affects the central electronics compartment too, I decided to make that larger as well probably to the relief of many that wouldn't know how stuff all their electronics into that tight a space. Overall size will be 50mm longer in total. I hope to have the revised plans done before the end of this weekend. Last edited by Saturnus; 27th March 2014 at 02:57 PM." Håber at der er nogle der kan hjælpe med svaret ?

I'm finally back. After having done extensive calculations. Scratching my head and redoing them a couple of times, I can now finally say that I found out what the problem was. It turns out my calculations were correct all along and that WINISD online calculates both closed and reflex cabinets incorrectly. Please be warned about this. Please use a different cabinet calculator or use the actual formulas. That means the sketch-up drawing already posted of the MINI is correct except that you might wanna exchange the double front with a single 12mm instead as commented earlier. To the filter there's not much to say. It's pretty self-explanatory. However, I strongly recommend using the ferrite choke if you are using a "filterless" class D amp like a maxamp20 or a Sure TPA3110. Even if you are not it is the better sounding option but the chokes that match can be tricky to find. The filter is for the MINI only. Another one will come for the Micro or a dual amped MINI. A dual amped MINI is basically to get the very most out of the speaker you can use the SP60/4 instead of SP60/8. That means each side of the speaker is effectively a Micro and so must be dual amped and use the filter for the Micro.

Tusind tak for svaret og ikke mindst dine fantastiske designs 😄 Jeg havde fuldstændig overset det indlæg. Må være på grund af for meget arbejde og alt for lidt søvn 😅 Så kan jeg komme igang med at bygge mini'en her i weekenden 😄
glæder mig til at se billeder :)

Det ser godt ud. Jeg har fundet et batteri næsten magen til hos batteribyen: http://www.batteribyen.dk/panasonic-...-3400mah-20765 De har også denne "batteripakke": http://www.batteribyen.dk/lav-din-eg...kobe-batterier Men jeg i tvivl om, hvorvidt jeg skal købe denne batteripakke i 12v, 13.2v, eller måske noget andet? Hvad er at foretrække, Saturnus? (det skal trække en 12v forstærker)

12.8V bliver det med 4 celler. Det er perfekt.
Det lyder godt. Er det rigtigt forstået, at kapaciteten med 4 celler vil være: 4*2,3Ah = 9,2Ah ? Også selvom den leverer 12v ? I så fald vil de 4 celler jo have hvad der svarer til 9,2/0,8 = 11,5Ah for et alm. bly-forbrugsbatteri. Er det ikke korrekt?

Nej. Du lægger spændningerne sammen når de er i serie og kapacitetterne sammen når de er i parallel. Der er enten eller.
Okay, så lyder det hele realistisk igen. Det andet ville jo også være for godt til at være sandt. Er det realistisk, at jeg lægger en stak af disse i serie: http://www.aliexpress.com/item/10PCS-LOT-Original-A123-systems-battery-High-Power-Nanophosphate-LiFePO4-cell-26650-2300mah-battery-batteries-with/1011724429.html Og så bruger denne for at få en fast spænding på 12v ? http://www.ebay.com/itm/New-DC-DC-LM2596-Step-Down-Adjustable-Power-Supply-Module-Converter-DC-1-3V-35V-/380755874794?pt=LH_DefaultDomain_0&hash=item58
