    Passive or active subwoofer?

    Hi there, I have a JBL control sb5 passive sub 40-120hz. They have a crossover of 120hz and the frequencies below this are taken from from attached Monitor Audio Bronze 2s. They say having a powered sub takes the heavy lifting off the main speakers, but my Audiolab 6000aMk2 only has pre out (no...

    Should I use this passive radiator?

    I have a 2.0 PC speaker system, whose drivers have a diameter of 70mm (that's the diameter that actually moves, if that's of any use). Will the passive radiators shown below be suitable for these PC speakers? I've read elsewhere that a PR should have at least the same diameter as the driver, but...

    Suggestions for modern, passive bookshelf speakers under $400

    I have two separate stereo systems that use a common set of speakers (I've built a switch box to switch receivers to the speakers). I am currently using an older set of Magnavox floor standers for speakers and I would like to upgrade to a pair of passive, modern bookshelf speakers...

    'Ohmm' P212. Rip off of Ohm speakers or genuine vintage?

    Please scroll to the bottom of my post for pics. I have just bought the pair for a price which I am willing to disclose if anyone can tell me the value of these :) I googled the hell out of them and could not find an identical speaker at all. Seller claims they are from the 70s and were used...

    ? Passive sub....use AVR or seperate amp?

    Thinking about buying a Canton Plus C subwoofer to add to my system. Will it perform as well using my approx. 2004 era Denon AVR-687 or should I use a dedicated amp for the Canton Plus C Are there any advantages to either scenario? What is the minimum wattage needed to make the sub "sing"...

    Passive Subwoofer question Canton Plus C

    Hi all. I have a Canton Plus C passive subwoofer that is designed to be only used with dedicated Plus S satellites. The crossover is wired internally with a 120hz crossover (would like to change that to 80hz) and results in a 4 ohm load when the sats are connected. I would like to be able to use...

    KEF BD139 re-foam or replace?

    As far as I am aware there are no oval surround rubber/foam kits available. I am also aware there were different variations of this passive radiator such as the "missing-D" model, the B139. Should I look for a pair of these? Are they interchangeable, spec wise? Am I wrong and the surrounds on...

    Do you really need a preamp?

    Forget for a minute all the obvious reasons for having a preamp (boosting signal strength, noise reduction, switching, etc.): is a preamp must-have sonic component for 2-channel listening? If so, why? I recently auditioned a vintage solid state Japanese Class A/AB dual mono solid state amp...
