Summarize the following:
The variety of speaker builds suits individual speakers for different tasks. For casual music listening, a pair of bookshelf speakers would be more than enough. Those who desire a more intensive experience can upgrade to standing speakers. Surround sound systems are also a high-end option.  Subwoofers are additional speakers that add depth to bass, which is low tone. They’re good for movies and music with lower range such as rock and metal.  For adding general depth to TV and movies, a soundbar or soundbase is an option. These take up less space, require less wiring, and can be combined with a subwoofer. Wireless and wall-mounted speakers benefit from portability and offer new sound angles in your room. For gaming, small specialized speakers usually offer enough sound. These are placed on a desktop near the computer and have magnetic shielding. Different surfaces affect sound quality. Hard, flat surfaces reflect sound and soft or varying surfaces absorb sound. Sound is also easier to hear in a small room. To get a sense of the room, stand in the center and clap. The less the sound carries, the more powerful the speakers you’ll need. A small room such as a bedroom is fine with bookshelf speakers, but a large carpeted and furnished room benefits from bigger speakers. While bookshelf speakers will fit in a small bedroom, you wouldn’t want to try to fit wide standing speakers in there. The sound can overwhelm a small room even if it has lots of absorbent furnishings. On the other hand, if you want a surround sound system for your television, the speakers need space away from the wall and surround you.  Where you’ll put the speakers matters. Speakers inside a cabinet, for instance, can get muffled, but so do speakers in room corners since the sound is distorted by the walls. Speakers benefit from being three to four feet away from the sound source. This helps them project sound into the room. Try to keep your speakers around ear-level. At that level, the sound will be clearest to you. It’s very easy to fall into a price tag trap. You’ll see bigger and better-looking speakers or a salesperson will refer you to them even though quality isn’t completely related to price. A cheaper speaker may work better for you than a more expensive one. Stick to your budget as much as possible. Once you’ve decided on the type of speaker you need, go online or shop around in stores to compare prices. Determine how much you’re willing to pay for the kind of speaker that seems right for you.

summary: Decide how you’ll use the speakers. Consider your room’s furnishings. Determine the space you have available. Consider your budget.


Summarize the following:
Don't bleach hair that is freshly washed. The bleaching process will dry your hair out significantly, potentially causing damage and breakage. Your hair's natural oils will prevent this. A freshly-washed scalp is also much more sensitive and will itch more during bleaching. Your bleach kit will have two main components: dry powdered bleach and a hydrogen peroxide solution. Mix the two according to the ratios or instructions on your dye kit, using a tint brush or plastic spoon.  Follow the instructions on your kit if they are different from what is described here. Developers come in different strengths rated by numbered "volumes." If your hair is already fairly light, use volume 10. Volume 20 is for darker blondes, volume 30 for light browns, and volume 40 for darker browns and black.  Higher volumes can be more damaging to your hair, but they can also lighten it faster. If you've never bleached your hair to platinum blonde before, you will need to know how long it takes your hair to lighten. Select a small amount of hair close to the roots at an inconspicuous place and section it off. Brush on some bleach using a tiny brush. Let the bleach set and check the strand every 5 to 10 minutes. If your hair is not light enough after an hour, you will need to do multiple rounds of bleaching. Rinse the bleach away between rounds and reapply it. To minimize damage, do not leave bleach in your hair for over an hour. Use a tint brush to apply your bleach mixture evenly to your hair. Work in sections, brushing in the direction your hair grows.  Start from the very back of your head and work your way forward, leaving the sections of hair that frame your face for the end. If your hair is thick, flip up each section to expose the next layer of hair underneath and apply there, too. Leave about a one-inch section around your roots to do last, after the face-framing strands. The heat from your scalp will cause your roots to bleach a little faster than your normal hair. Try to go as quickly as possible to ensure an even color. Refer back to the results of your strand test to determine how long you should leave the bleach in your hair. Cover your hair up with either a shower cap or plastic wrap while you wait. Keep in mind that a little itchiness on your scalp is normal. Use warm water without shampoo. Be very careful to not get any bleach in your eyes as you rinse. If possible, ask someone to rinse your hair for you in a sink while you look up as if you were in a salon. If you aren't immediately moving on to the next step, allow your hair to air dry. Blow drying can further strip your hair of moisture, potentially exacerbating any damage the bleach has caused.
summary: Wait a day or two after your last shampoo. Mix bleach powder with developer. Do a strand test. Apply the bleach. Let the bleach sit. Rinse out the bleach.
