Product Description
Taking advantage of the newest developments in materials science and acoustic design the In Phase XT component loudspeaker systems combine purity and sonic accuracy. Glassfibre cones offer a combination of very light weight and incredible resistance to resonance and distortion due to their pistonic behaviour. The sweet sounding silk textile dome tweeter drivers are made with the Rare Earth Neodymium magnet material, which offers twenty times the magnetic power of conventional ferrite types and feature Aluminium voice coils. Solid phase plugs in the centre of the midbass drivers create a coherent and phase-accurate output, while carefully designed passive crossovers ensure correct frequency division of labour within the system. The first review in a leading magazine covering car audio said it all, ...New boys on the block In Phase boast huge power for your doors, fantastic build quality and awesome sound... In Phase components; when a compromise just wont do. 13cm, (5.25) 200w (max) Glassfibre component speaker 2 way Silk dome Neodymium magnet tweeter 9oz magnet Impedance: 4 Ω 97db 1w/1m 50w RMS

Speakers okay - pity about the crossover network. June 7, 2009
D. Briggs (Bath, UK)
In Phase XTC5 Speakers 200W, 2 Way 13cm component systemThe speakers seem to be fine. They sound better than the original speaker fitted in my car, although, the 13cm speaker chassis seems to be made from quite thin sheet steel when compared with others I have seen.
The main problem is in the design of the crossover network. The design for the low freq. speaker is a 12db/octave L/C network and that looks fine. The problem is with the high freq. speaker network which is a 12db/octave C/L network, the C element of which seems to be two capacitors in series, a disc ceramic and a non-polarised electrolytic.
The design of the printed circuit board is such that without modification they can only be connected in series.
Usually such capacitors are in parallel the disc ceramic making up for the poorer high frequency performance of the electrolytic.
Also what's the point of putting two capacitors in series, the lower valued disc ceramic is going to dominate and they could have saved money by getting rid of the electrolytic. Looks like In-Phase need to review their QA.
All this of course can easily be put right with a soldering iron, drilling some small holes, changing the series capacitors to parallel capacitors by moving one and installing a link. As I said, pity about the crossover network.
After correcting this, there is then the question of non-polarised electrolytic capacitors and their long term characteristics but perhaps I should stop there.
I wonder how common this is, or am I the only one with rogue printed circuit boards and series capacitors?
