Help me with my car and some misconceptions i probably have
First off thanks for all your input in this matter.
Im no audiophile and know little about the specifics of amps so if i sound dumb.. well, i guess i am, and thats where you come in. Ok, had a band pass in my car. 2 10's. Sounded good. Ended up blowing a speaker. Replaced them. Not sure if im getting the same bass i was getting. Seems my older speakers could go to a louder volume with more bass. These seem to poop out sooner and then have the bass break up. My first possible misconception. I was under the school of thought that the bigger the magnet the more bass the speaker could put out. The speakers that i bought, the magnet, is about 2/3 the size of the orginal. Is this magnet theory true at all? Second possible misconception: I was also under the school of thought that if your amp wasnt strong enough, at loud volumes, the speaker would break up (Like its doing now) and if the amp was too strong that the speakers would pop due to too much power. True or not true? It seems im getting alot of, if not more, bass at lower volumes that i was with the old speakers. But like i said, seems when i turn it up loud the bass doesnt keep up like it used to. Im running an offbrand 600 watt amp that is just powering the bandpass. My head unit is 52x4 but i dont think that has an effect on the band pass cos it goes through the amp first? And on a side note, not sure my amp has any type of tweaking screw/knob to set the amp for max output at any givin loudness but im going to look during lunch. Im going to return the speakers today if it comes back from you guys that i should.. or im just going to hold onto them if it sounds like im probably doing ok and im just being mental like i tend to do. Thanks for the input again. I appreciate it. H |

Magnet size means nothing. A good qaulity sub is what you need. Stay
away from swapmeet brands. You can destroy and amp/subs with any amount of power with abuse. You should not run your subs into distortion. And you should not run your amp until it overheats all the time. If you set your gains properly you should be ok. |

The speakers that i bought, the magnet, is about 2/3 the size of the orginal. Is this magnet theory true at all? Not really. Magnet size has nothing to do with bass output. Second possible misconception: I was also under the school of thought that if your amp wasnt strong enough, at loud volumes, the speaker would break up (Like its doing now) What do you mean by break up? If your amp does not have enough power to meet your listening demands and you drive it to clipping then you could hear some of that distortion. Although in a bandpass box that would be harder to hear due to the design of the enclosure. and if the amp was too strong that the speakers would pop due to too much power. If you drive the speakers beyond thier mechanical limits then you could hear a pop sound of the speaker hitting the magnet. Certain speakers are designed to work within a specified airspace according to box design. I would suggest one of two things is happening. The first is that you have innappropriate speakers for the box parameters/design. This would be my first choice. Take them back and either find something that works within your given box or buy a new box and appropriate speakers. Two: Your ears do not remember sounds all that well. It is possible that you are hearing things that aren't there, or perhaps you are listening more carefully and just didn't notice your other speakers did the same things. This is less likely in my opinion in your case. Les |

My first possible misconception. I was under the school of thought that
the bigger the magnet the more bass the speaker could put out. The speakers that i bought, the magnet, is about 2/3 the size of the orginal. Is this magnet theory true at all? Kinda sorta...well, not really. It's not a matter of how much bass it can potentially give you, but rather how much bass it will put out *based on the amount of power you're delivering to it*. This is essentially the sensitivity of the speaker (among other things), and it dictates volume per watt (not entirely true, but close enough). So, you may have just bought a speaker that is less sensitive than the other one, so it's not playing as loud and when it's starting to break up, what you might be hearing is your amplifier clipping. Then again, maybe you just bought an inferior speaker that just can't handle as much as the old one. Or, it may just not like the bandpass box you put it in. Second possible misconception: I was also under the school of thought that if your amp wasnt strong enough, at loud volumes, the speaker would break up (Like its doing now) and if the amp was too strong that the speakers would pop due to too much power. True or not true? True. If your amp is powerful enough, it will reach its limits and start delivering a distorted signal to the speaker. If the amp is too powerful, the power might be too much for the speaker causing the speaker to generate the distortion (and possibly blow). It seems im getting alot of, if not more, bass at lower volumes that i was with the old speakers. But like i said, seems when i turn it up loud the bass doesnt keep up like it used to. Im running an offbrand 600 watt amp that is just powering the bandpass. My head unit is 52x4 but i dont think that has an effect on the band pass cos it goes through the amp first? Right. And on a side note, not sure my amp has any type of tweaking screw/knob to set the amp for max output at any givin loudness but im going to look during lunch. Im going to return the speakers today if it comes back from you guys that i should.. or im just going to hold onto them if it sounds like im probably doing ok and im just being mental like i tend to do. I'd first try to dig up the manual for the speaker to see what kind of enclosures are recommended and what size they should be. Once you verify whether or not they're in the right box (if they're not, return the speaker and get one that will live happily in a bandpass the size you have), then it may be worth considering buying a new amp or more sensitive subs. |
