To stradlemonkey:
I would most likely set the Bose 4001 to large. With your Pioneer receiver, I'm assuming you can set the crossover frequency for the 4001s. According to the sub you have and how well it produces the upper frequencies without soundy boomy, I would set the lower frequency limit to the Bose speakers at around 80Hz. This will give you almost no dip in bass response from your Bose, transitioning to your sub. Also, it is generally said that frequencies below 80Hz start becoming omnidirectional, so you shouldn't be able to notice that the bass belowo 80Hz is not coming from the Bose, as long as your sub is in its sweet spot. Also for a home theater setup, you have a center, so try placing the tweeters out, like you say to provide a more 360 sound field. You may find that you prefer them facing you, toward the center, even still, but try it. If your center can pump out some good volume, you may get a larger sound by placing the tweets out.
A note about your sub's sweet spot. In case you don't know, one of the best ways to find the best placement for your sub is to move your seating out of the way and place your sub exactly where you will be sitting. Then, walk around your room while playing some bassy stuff, and the spot where you get the best sounding bass is where you should place your subwoofer. it is better to lean over, stoop down, to the ear level that you will be in while you are seated. You'll look strange doing it, but it will provide a better approximation of how your sub will sound when you are seated.
As far as crossing over your Pioneers, try hooking them up by themselves as main left and right speakers, not crossed over at all. Be careful, and see what they'll do. Please be careful. lol. Then, still in 2 channel setup, start crossing them over (lowest crossover point first, then gradually going up in Hz) until you are able to play the Pioneer speakers comfortably (no speaker fatigue) at the volume you will be listening to movies. Since Dolby Digital, and especially DTS (not to mention True HD, and DTS HD) will send bass to those speakers from time to time, using this method will ensure that those big explosions and such will not blow the speakers.
Using this method will allow you to safely test the limits of the Pioneer speakers, and once you have them mounted you will not have to worry about blowing them.
Hope this helps! |
