Design and connection

I'm probably going to build a set of speakers in the near future and wanted some advice.

First. I was wondering how connecting two drivers in series would effect the total sound of a speaker. I ask this because I was thinking of building a set of speakers with two 6.5" or 8" woofers. I haven't decided whether to use an MTM design or just stack them (TMM). The amp I will have to use for the next while is an old Technics integrated amp, which has an impedance rating of 8-16ohms. This is why I want know what the series connection will do, since I can't run a 4 ohm speaker.

Second. My other choice for speakers is to make a three way design. I would use a 1" dome for highs, a 6.5" for mids, and a 10" or 12" for lows. I was thinking of using a side fireing woofer design, but am worried about the "boomyness" of the side firing woofer, if set too close to a wall. Would it be better to use a front firing design?; or just seperate them into two bookshelves and two subwoofers. I can run the amplifier in 4 channels so I could run two bookshelves and two subwoofers, if I wanted to.

I don't have too much money to spend, and since I live in Nova Scotia I'll have to order the speakers from the US. So I will probably use Madisound or Pioneer drivers, because of their price. Any help would be greatly appricated.

Thanks in advance.
