    im very sorry for asking you this guys, but im basically need some sort of lesson in regards to speakers , cables and amps as i am, as you probably geussed a complete noob.

    Could someone clear this up for me. Firstly i have a acoustic solutions ds534 and would like to replace the speakers. Could someone help me with what speakers this amp can be used with? ( e.g i keep seeing frequency range and impendance 8ohms, what is this?)

    Well basically i need some kind of lesson with this stuff lol( what speakers i can use, what wires i can use etc) as i really have no idea what i am doing :suicide:

    I would appreciate any time you waste to help me as until i learn about this stuff , im always going to be in the dark:rolleyes:

    Thanks

    Without trying to sound patronising or cause any offence I'm not sure the unit is worth changing the speakers on; It's a very basic Amp. & the chances are that whilst it may sound better with some Quality speakers you would run a high chance of damaging the new speakers by over driving them with a low quality amplifier. The ohms are the resistance of the speaker; it is not advisable to say put a 4 ohm speaker on an 8 ohm Amp. but is acceptable the other way around. In real terms the speaker impedance changes all the time so even if rated at 8 ohm's it could easily drop below this figure. Frequency response depicts the extremes of sound the speakers can do from Bass to Treble (Low to High) basically the lower & higher the better but satellite speakers do not need to go low as you have a Sub woofer for that.
    With regard to cables just basic speaker wire will meet with your requirements (not the ultra thin bell wire stuff that comes with all in ones but something perhaps twice as thick). Hope this basic explanation goes some way to answering your questions but in all honest I would consider a better Amp. etc. if funds permit. :)

    thanks for that paul, Im beginning understand most of it now.:smashin:

    No offence taken with comments about my amp, i know its utter poop, but unfortunatly im cash strapped at the moment lol.

    With regards to buying some speakers, i was thinking of getting some second hand acoustic solutions av 120's
    or something along these lines:
    home cinema speakers gale movie star floor standers on eBay, also, Speakers Hi Fi, Home Audio Hi Fi, Consumer Electronics (end time 31-Jan-09 17:28:00 GMT)

    or these

    Gale 30 Series Speakers on eBay, also, Speakers Hi Fi, Home Audio Hi Fi, Consumer Electronics (end time 31-Jan-09 11:39:07 GMT)

    could you tell me wether i am being too ambitious with my speaker selection, or would my amp be capable with these speakers?

    Thanks again
    ryan

    I understand what it is like to be on a tight budget, so you have my sympathy.

    But, the system you have is rated at 100 watts, and I can only assume that is 100 watts total power, which in turn means 100/6 = 16.7 watts per channel. Though it is probably fair to say that they give a little more power to the Sub, which in turn means <15 watts each for front, center, rear, and >25 watts for the sub. That is not a lot of power, and may full sized full range speakers are going to struggle under such limited power.

    I would personally say you need a minimum power for each channel of +30 watts, and would generally recommend that people not consider amps with less than 40 watts of real power.

    So, I think it is going to be difficult to get speakers to replace your existing speakers. The window of available speakers is very narrow, and there is little to no way to know in advance whether a give speaker will effectively work with your amps or not.

    The only speaker I can think of that has a low power requirement is the Mordaunt Short Avant 902i which are £117 per pair, but have a 15 watt minimum suggested power.

    Really though, if you don't give us a budget, we can't really make any recommendations.

    If you are determined to buy new floorstanding speakers, I would suggest you keep what you have for games and such, and save up and buy a nice stereo amp for roughly £150 or more, and connect your new floorstanding speakers to that.


    Here is a fair explanation of Frequency Response -

    Only moderately helpful, but here is some general information -

    This should certainly be more helpful -

    And some worthwhile details here too -

    That should help answer a lot of your questions.

    Off line, Raymondod asked me for some specifications and recommendations for a new replacement amp. I think that is probably a fair continuation of this thread, so I will post my response here.

    First, you need to decide whether you are looking for an AV amp or a Stereo Amp. An AV amp is probably going to cost more, but a Stereo amp for the same money is going to be a better amp.

    Next, you need to look at what you are going to connect to the amp. If you have a gaming system, that might require a special connection (optical, coaxial, or HDMI). A stereo amp won't have those connections, or is not likely to have them. However, your TV probably does have those connection, and you can connect everything to your TV and run the standard Audio Outs of the TV into the Stereo amp.

    But, one way or another, you need to make sure you have some way to connect all the things you need to connect.

    While it is possible to buy a reasonable AV amp for about £200, the good ones don't really start until about £300, and a preferred amp would be closer to £500.

    A reasonable stereo amp can be had in the range of £150 to £250. I would suggest an amp of at least 40 watts RMS per channel. 'RMS' (or FTC) is a rating standard that is probably going to give you the lowest numbers for power, so you can be sure you are getting at least that amount of power.

    Dynamic, DIN, and IEC tend to be inflated but can still give you an idea of how an amp will work under real conditions. Personally, I always use RMS/FTC to 8 ohms as my starting point.

    Keep in mind that the Stereo amps are integrated amp, meaning all the controls you will need, but no radio, no AM/FM. Receivers with AM/FM are going to be closer to £200 to £300.

    Amps that I've seen that look good are Pioneer and Yamaha. Not sure of the prices but some like Arcam, NAD, Cambridge Audio, Sony, and though I don't trust the power specs, some Onkyo's look nice.

    Hope that is enough to get you started.
