Heybrook HB100

[acorn]

I have a pair of Heybrook HB100 speakers, and I just discovered that the crossover in them consists of one 3.3uF capacitor and a 2.7R resistor , does any one know why so few components were used in these crossovers and would it be worth while upgrading.

I also noticed that they use metal cone tweeters.

Though I am not familiar with these speakers I assume they are a 2-way design.

However the components you describe if wired in series would indicate a simple Impedance Equalisation Circuit which is normally wired across the mid-woofer terminals.

Hi all,

Yes 2 way I think and Heybrook used minimum xover components as part of the design ideals iirc.

I guess this will be the mid/bass connected directly with a natural hf roll off and the tweeter connected via a series resistor for level matching and the series cap as a first order high pass.

Hi again Acorn, this is how I think it will be at present.

Top is if it is single wire connections, bottom is if it is bi-wire, or if you want to try bi-wire.

Changes could be,

trying bi-wire

increase or decrease the R value which will decrease or increase treble level relative to mid/bass

increase or decrease cap value which will lower or raise the high pass frequency for the tweeter
