    Default Do different speakers play different frequencies?

    I have a pair of Monitor 60 series II's and a HK 3480. When I put my ear right next to the top speaker, separating out the sound from the tweeter with my hand, it seems like the speakers play progressively lower frequencies as I go down the towers. Is this just in my head or are there crossovers for each of the speakers in the towers? Also, I was curious and stuck my phone inside the port and took a picture facing up into the tower and found a separation between the bottom speaker and the rest of them. Here's the picture, http://i.imgur.com/Dnnad52.jpg I looked for a cabinet design, like a cutout, so I could see what the inside looks like. Anyone know of one?

    Hello, kadrek. I think you may be confusing drivers for a "speaker" and yes, different drivers have different frequencies. A tweeter will have the highs, a mid driver will have the mids and a woofer will have the low frequencies. A crossover separates the frequencies delivered to each driver within said speaker.

    The lower freq. stay lower to the floor then the highs if you put your ear level with the carpet you will just barely hear the sound because it is just too low hence the term "low freq.", but on the same token if you put your ear against the ceiling the highs will be very bright hence the term "high freq.". Give it a try and let us know what you find.

    Hey kadrek welcome to CP. Just to say you are correct in what you hear from each speaker. I believe it has to do with the makeup of the speaker and the crossover points. I have looked all over the net and I cant find a cutaway view either. Why are you curious to know if I might ask?

    WELCOME TO CLUB POLK!

    You are correct, your drivers do play at different frequency ranges. I am not sure exactly where the crossover points are on the M-60s. The M-70s (a model up) have a 2 1/2 sloping crossover. So that the upper mid drivers cut off at a higher point than the lower drivers. And, of course, the tweeter takes up the High End to 24Khz or so.

    We all have to begin somewhere. I remember when I was a teenager I would always judge a speaker by HOW BIG that low frequency (woofer) driver was. The "bigger" the "better". That's obviously not the case, although size and magnet assembly have to be taken into consideration when designing a speaker. Youngsters love "bass" so we were always looking for what people today would call a garage rig?

    The M-60s should sound pretty good on an HK receiver!

    Enjoy!

    Thanks, just out of pure curiosity.

    I know that different sizes of drivers are used for different frequencies. I was just wondering if each of the drivers in the towers had separate crossovers.

    Ok, valid question. In your speakers there is one crossover, which acts as a traffic cop if you will, sending the appropriate frequenices to the respective drivers via capacitors, resistors and inductors.

    From the picture, it looks like the crossover breaking out the leads to the various woofers, so I would presume each one is reproducing different frequencies.
