    Mash Up of Kits

    Hello Tech Talkers, a few weeks back I made a little boom box with the 300-7300 30W Portable Bluetooth Kit. I added a second battery board for extra life. It sounds pretty good and overall I am very pleased. While I like what it does and feel the output is appropriate, my father wants me to build him one. He is a "more is better" type of guy. I was looking to make a version that would mash up the 100W Dayton Bluetooth amp with a few sets of batteries and the Overnight Sensations. Ideally I would buy the Overnight Sensation parts but not the enclosure. I would like to make it into a single enclosure, maybe even share 1 larger port. If a single port would cause issues, the 2 with the kit is fine as well. Maybe 10 X 5 X 8 inside dimension. The amp and batteries will take up volume that is not yet accounted for. I am no audiophile and neither is pops, but I would like to put something together that is loud, accurate and clean. Thoughts? Suggestions? Thanks in advance!

    Lucky father! Although now he can brag that "mine is bigger than yours".

    Never did post the results...
    Used the KAB-230v3 and 3 battery boards.

    Thanks for the tips.
    Wolf, the ID's are about 8X5X7 each on the OS, giving me 280 ci. But yes, I think I should aim more like 8X7X10. That will yield double the volume.
    Mike, the rigid front handle is to carry on end and be a bit of protection for the components. This is a garage/camping/general outside toy.

    If your buying parts separately, go with the KAB-230 amp board. Of the three KAB series amps, that model is best - no issues. And for maximum output on 8 ohm (e.g. OS) speakers, use a 24 V PS (but an old 18-19 V laptop supply will be very good as well).

    BTW: Nice build. Love the inside mounted woofers with contoured baffle openings. Maybe a soft, handle on top?

    I believe 10x5x8 is about the size of ONE OS box. If you change the volume, the bass response will be altered.

    Later,
    Wolf
