2way, 21/2way, 3way, 31/2way speakers
A x.5 way mates an x-way speaker with an additional low frequency driver that only has a high pass filter. It lets the designer compensate for baffle step loss without giving up 3dB or more in sensitivity.It is not possible to build a conventional... 
What size screen for front projector?
The right answer is what works for HIM with HIS projector. He needs to buy it, set it up on a white wall/sheet/cheap screen, and see what subtended field of vision works for him. Preferences vary and will change when he gets used to thinking of hi... 
Here's a challenge:a class A sound system for less
Think about your placement constraints. Speaker and listener placement have as much to do with what you hear as the speakers you buy and more to do with imaging and sound stage. Speakers not designed to be placed near a wall will have bloated bass... 
Bookshelf Speakers on Bookshelves?
There will be a noticeable lower midrange boost that makes singers sonud like they have chest colds if the speakers were not designed for on-wall placement. 
VCR for analog TV as well as HDTV
You do NOT want to mix VHS with a larger, sharper screen. The horizontal luma resolution is about 320 pixels so the image will be very soft. Buy yourself an S-VHS recorder for about 530 pixels horizontally if you must retain backwards compatabilit... 
Can you help or do I have to get divorced?
Buy a nice set of head-phones.If you insist on speakers you want to look at horns.If you don't like horns you need something specifically designed for on-wall placement. Anything else will have an anoying lower midrange boost. 
Electrostat transparency from conventional speaker
>Only reason people tolerate electrostatic speakers today is because they are dipoles, thus they are a functional 4 channel systems or primitive surround sound system (2 direct ch., 2 delay ch. (see audioK's post) The physics do not agree with ... 
Help on soundstaging
Move them a more healthy distance from the front wall. The greater of 4' and half the distance between listener and speakers is a good place to start. More than that is better. You also want to maintain the same minimum distance between the listen... 
Speaker phase and timing
Speaker, listener, and furniture placement have more to do with imaging than your equipment.Spousal friendly placements with the speakers or your chair just a foot or two off the wall behind them will not be good. A television between the speakers... 
Rear Ported Speakers, Backs to Wall?
Port location doesn't matter as long as you have a few inches of clearance to avoid slot loading and aerodynamic noise.Speaker location matters a lot, arguably as much as the equipment. You get a substantial increase in output (perhaps 5dB out of ... 
12db/oct 80hz hipass filter
You want the acoustic response of your sub-woofer and main speakers to sum flat.If your main speakers have an F3 at 40Hz or below you'll get closer to that if you add a 2nd order line-level highpass with poles at 80Hz, Q=.707.If they're sealed sta... 
Which Speakers?
Where you sit, where the speakers are, and what acoustic treatments you use are all going to have a _huge_ effect on what speaker works best for you.Much more than the room size. 
Great sounding close to back wall speakers.
Having a front or rear port location doesn't matter once you get more than a few inches out from the wall.Within the ports operating range the sound waves are _very_ long (28 feet at 40Hz), wrap arround the speaker like it wasn't there, and the sp... 
Has sonic perfection been acheived?
Maximum output at xmax in a sealed box will be 76dB @ 80Hz, 88dB @ 160Hz, and it finally becomes useable with 100dB of output at 320Hz.If you prefer your music at realistic levels you'll need either a cross-over in the middle of the human vocal ra... 
are rear surround sound speakers having same sound
While there is no 7.1 source material, most decoders don't send identical signals to the surround back speakers.THX-EX extracts surround back the same way a Dolby Surround decoder handles the center channel and applies a phase shift between the tw...
