Enjoy the new speakers.
I am not suprised that they sound better than bose, most speakers do. The Bose sats cut off around 200 Hz and the "Bass Module" only goes down to 60-70 Hz.
WOW i did not think that "bose" was that bad, and in New Zealand as you can probably imagine being far away and all from everything, electronics are quite expensive dad paid a fortune for them. I am glad he only got the sub with 2 sat speakers but it does make sense to buy dedicated speakers. And "bose" only have a mid to high range speaker in their sat speakers so all the high percussion (or how ever you spell it) sounds are very muffled and you can forget about bass but thats why i guess you get the sub.
Sub for low freq sounds and mid to high for main, centre and surround speakers.
The reason i do this is because when your amp/reciever does the signal analysis (ie digital filtering on each channel) it can produce a much higher order filter through mathematical algorithms allowing for much better cut off and pass-band responses which is not possible in the analogue domain. Writing code for a DSP (digital signal processor) to increase filter order is much simpler than having to string heaps of analogue components together and here is why if you are interested.
Or should i say harder to do in the analogue domain thats why the speakers which are 3 way are so much more expensive. Because the signal sent to your speaker is analogue hence you will need high order and low loss analogue filters.
3 filters to be precise:
1 low Pass, for the woofer
1 Band Pass (high low - low high)
1 high Pass, for the tweeter
because filter design is very tricky in the analogue domain especially getting a good frequency response in such a small range. Hence expensive circuitry is required (usually inductor-resistive and capacitive) which also makes the speaker heavier but who really cares about that in the end any way its not like you need to shift it once its all been set up right ! But the big problem is the loss due to the 3 different paralleled filters.
Its pretty simple the higher order the better frequency response you have to the ideal case but the bigger the signal loss you have over the filter which cant be delivered to the speaker and your speakers sound quite.
That is why i use 2 way speakers for everything. Not that i am saying a 3 way speaker is bad, dont get me wrong but to get a good 2 way speaker it costs the same as a dodgey 3 way entry one or more so for anyone on a budget like myself dont get the biggest one thinking it will be best, (+ the misses will have a fit

) that was my decision making for my latest audio set up. a good 3 way speaker requires good analogue filter design which, take my word for is not a very easy task and makes them very expensive for all the engineering efforts gone into the design.
While testing the JENSEN floor standing speakers (3 way) in the store even "tho my god do they look HOT"

!! they do suffer in the bass department and cost as much as a the sub + the bookshelves, i know this is not the case in all (3 way) speakers, there were some DALI floor standing ones next to them which did not have this problem but where again almost twice as expensive.
So your best bet from my point of view to get an excellent sound invest in good bookshelves and add a sub to it and my god your friends will be over every weekend wanting to watch their loved movies on your system
Dont be fooled by the sales man/girl just because the speakers next to them ,the DALI's in my case where twice as expensive means they sound better plus if you add a sub later on it will most likely over power the DALI's woofer anyway so all that extra money would have been wasted and you might as well have a pair of book shelves to begin with.
The only problem is bookshelves suffer from low power handling capabilities mine only are rated for 110W but who really turns their amp up every week to the max, you will be deaf by the end of the year if you do that lol. and i am more interested in clarity not how loud it goes even tho i showed the neighbours who is boss last night with my sub (given i was showing off to my mate a little also).
