What You Are Buying
An Xcelsus Primum XP6.2B component set from a discontinued line. Two woofers, two tweeters, two external crossovers. We are not restocking it.
Xcelsus is an Australian brand and the Primum series was their mainstream component offering. The interesting engineering here is in two places: a paper and fibre composite cone rather than the polypropylene that dominates this price tier, and a liquid-cooled tweeter, which is not something you usually see on a 6.5 inch two-way.
Read this before you buy
Final sale. No returns, no exchanges, no manufacturer warranty. This is a discontinued model with no replacement pipeline, so a failed driver cannot be matched. If you need warranty coverage, buy current production.
Reading the Specification
50Hz to 20,000Hz
A 50Hz lower limit is genuinely good for a 6.5 inch component woofer, and it is what the paper composite cone buys. Paper is lighter and stiffer for its mass than polypropylene, so it can move air lower before the cone starts flexing rather than pistoning.
25mm liquid-cooled tweeter
Ferrofluid in the tweeter gap conducts heat away from the voice coil and damps the resonance at the same time. The practical effect is a tweeter that survives sustained power without compressing. On a 25mm dome it also allows a lower crossover than the size would otherwise permit, though Xcelsus did not take that option here.
5500Hz crossover
This is the number worth understanding, because it is high. Most 6.5 inch two-way systems hand over between 2500 and 3500Hz. At 5500Hz the woofer is being asked to carry well into the presence region, where a 165mm cone starts to beam and its off-axis response narrows. In a car, where you almost never sit on axis, that shapes the character: expect a forward midrange and a top end that stays out of the way rather than one that sparkles.
Whether that suits you depends on the car and the source. On a bright factory head unit it is forgiving. If you want an airy, detailed top end, this is not the voicing that delivers it.
80W RMS, 120W maximum, 200W peak
Three figures because Xcelsus published three. The one that matters for amplifier selection is 80W RMS. At 88dB sensitivity, 60 to 80W per channel is the sensible band.
Component Format
Separate woofer and tweeter, joined by an external passive crossover, so the tweeter can be mounted at ear height instead of down in the door. That is the entire reason to choose a component set over a coaxial, and it is worth the extra installation time if you have somewhere to put the tweeter.
Plan the crossover location first
The crossover boxes are 120 by 65 by 33mm, which is large enough that they need a real home. Inside the door above the drain line, or behind the kick panel. Decide where they go before you start, not after the door card is off.
Fitment
- 165mm outer diameter, but check the 145mm mounting hole figure against your door, not the outer diameter.
- 65mm mounting depth is on the deep side for a 6.5 inch driver. Measure the clearance behind the trim, including where the window glass sits when it drops.
- 90mm magnet is part of why the depth is what it is.
- Tweeters mount surface or flush, wherever the interior allows.
Who This Suits
Buy these if
- You want the imaging a separate tweeter gives and have somewhere to mount one.
- You are running 60 to 80W per channel from an amplifier.
- Your doors can take a 65mm depth.
- You want a forward, midrange-led voicing rather than a bright one.
Look elsewhere if
- You want an airy, detailed top end. The 5500Hz crossover works against that.
- Your doors are shallow. 65mm rules out a lot of cars without spacers.
- You want a half-hour install; buy a coaxial.
- You want warranty coverage or the option to return.
Installation
- Test-fit the woofer dry, window up and window down, before any wiring. 65mm is deep enough that this matters.
- Mount the crossovers somewhere dry and reachable, and secure them. A loose crossover in a door rattles and eventually sits in water.
- Run amplifier to crossover input, then crossover outputs to woofer and tweeter. Never wire the tweeter straight to the amplifier.
- Check polarity on both drivers per side. Reversed polarity on one side is easy to do and hard to hear as a fault; it shows up as a vague centre image.
