  4. Four 1k Watt Amps Vs One 4k Watt Amp

    in Amplifiers

    Posted

    I've got a question and a point to debate. Same order.

    1. Please explain your statement.

    2. I have used a lot of amplifiers and crossover networks with subsonic filters. I cannot agree with you that the do the same. I may be incorrect on this, but I believe that most of them do not kill all frequencies below the set level, but just attenuate them by 12 or 24db or whatever they have listed in the specs on the subsonic. With a JL 1000/1, I can personally vouch for the fact that it kills the specific frequency and anything below it completely. (also, keep in mind that I am not attacking any amp in particular)

    I do not mean to come off combative with this, but full understanding will not be achieved until all questions are answered and any misconceptions are nullified...that really sounds like some Confucius stuff there.

    You are not coming off combative and I hope I'm not either! :) It's good to ask questions - so then you are aware and you know.

    THD+N represents the amount of distortion that is added to the signal when amplified...I don't believe RF posts specs of the THD because it is insignificant. I saw that JL posted on their website and I think it was 0.05%@ 4ohm 50hz. Now I was told by one of the engineers here @ RF that the human ear can barely detect 1% THD and here in the JL manual they are talking about 0.05% THD, so obviously compared to the RF amp (which I would bet is probably between .05-.50%) you probably couldn't tell a difference.

    Subsonic/Infrasonic filter - I believe on all RF amps that have this feature it cuts out frequencies below 28hz completely...So the sub doesn't have a chance of getting blown by a freq. below 28hz.

    Me personally, I would run the T40001BD like everyone else has said- and it's not because I work for the company :D It's just the convience factor and the amount of raw power this amp puts out is freakin' awesome!!

    More questions or concerns feel free to respond!

    Sorry, I meant to answer this earlier. The biggest three reasons that I am considering the JL's are this:

    1. I am not sure of the distortion rating on the RF, I know the JL's are clean enough.

    2. The subsonic filter on the JL is absolutely amazing IMO.

    3. The regulated power supply should give me full power at 10-14.5v. I will pay for that in efficiency, since I will need about 600 amps to play on theJL's constantly where I believe that 300-400 will supply the RF, but on the other side of that, if my voltage drops to 12v for a bit, I will not lose out on power during that time.

    I had one amp refurbed and the test data sheet that came back with it showed it putting out 1290-1297 watts at impedances ranging from 1.5 to 4 ohm. So in all fairness, JL is underrated as well.

    I don't mean for it to come across like I asked for opinions and then argued with them. That is far from my intentions here. I am about 90% sure on getting the RF's, I just need to know what kind of distortion rate they have.

    Thanks again everyone.

    I'm going to try and respond to your post.

    (in order of your questions)

    1. THD doesn't really matter - it really doesn't.

    2. Subsonsic filter is a subsonic filter - it's not really amazing it just does it's job. It might be set to cut off at different freq. level on both of the amps but it works the same regardless.

    3. Regulated power supplys aren't all that great.

    before nintendo was atari, collecovision , intellivision, commmodore 64 and many others i cant think of atm. even Neo Geo was in the same time frame as the first nintendo and killed it technically in every way but in 1985 people didnt wanan shell out 800 bucks for a system and 125 pergame so it didnt do well

    OH SNAP, NEOGEO! Remember the game, ART OF FIGHTING?

    i whine like a little bitch for months to get that system from my mom's but she said helll no. which I totally understand now seeing the price.

    But I remember one birthday she rented it from this local video store with a couple games... Was like playing at an arcade in yo house.

    AccordMan, It sounds like you didn't do your homework before buying the Wii...

    You can't compare the Wii to the Xbox 360 or the Wii vs the PS3.

    Yes they are all gaming systems but it's a totally different experience.

    The graphics on the Wii I would compare to the game cube (which I didn't own) and they are nothing special... It's just the interaction and the kind of games they have out for the Wii that attracted me to it.

    Nothing like kickin' back some beers with friends and tryin' to bowl on a game...except you gotta be careful to not let go of the controller!!
