Yup.... two way cross-over cabs!  :yes:

Seby ~~ we have upstairs neighbors ~~ we don't "blast" them ... but the sound is terrific.

I always use my pc speakers.   I have really good Altec Lansing surround sound speakers, though....they came with my Dell.

The only time I use headphones is when I'm out of town and using my laptop.  The laptop has really bad built-in speakers that make everything sound bad.

When I record, I never use speakers.  I record using my karoake machine, and it doesn't even have a headphone jack!

Cindy, Vocals are pretty high output,  as is an instrument like a piano. or synths.

I have 3-way 15" PA cabs as part of a studio setup.  If people are over, there really isn't anything like an actually full range PA system.  Problem is I'm underpowering these with a powered board rated at only half the wattage that the speakers can handle.....I've heard that underpowering speakers is pretty bad for them too.....I have NO idea how that works,.......Yet supposedly you can cause probs that way as well.

Steven,

only if you can't achieve the desired loudness without clipping the amplifiers. As long as you don't clip there is _no_ issue with underpowering!

The "underpowering" theory go this way: you buy speakers to match the loudness you want. To fully utilize these speakers without clipping you want amplifiers that can deliver an output power of ~1.5 times the speaker ratings. This ensures that for all sound preassure levels the speakers can handle you will supply them with clean (i.e. amplifiers are not clipping) power.

If you don't push your amps past clipping there is no issue with underpowering!!!

The only way the speakers can be damaged is if: 1) the range of tolerable excursions is exceeded, 2) the dissipated power in the voice coils burn the wire.

Hope this clears it up.

Morten.   I'll ask you about this over in the tech board.   It's been ages since I knew what this stuff meant, so I'm confused as to the differences between distorting with a high output instrument such as electric piano, and clipping.


IE  100 watt Soundtech quik-mix mixer turned up around halfway. Cones of Speakers (rated at being able to handle 300 watts peak each) start to crackle.
(15 inch 3 way speakers)  Checking cones and speakers I see that nothing is ripped, or blown.



Is this clipping ?  or normal distortion from the high output of a piano ?
