Raidho XT-5 floorstanding loudspeaker

Raidho XT-5

If you’ve been paying attention down at the back, you’ll have noticed that both the TD-4.8 and the XT-5 share a T in their product designation – although in this case that T is not a common factor. The T in TD denotes the use of a super expensive tantalum coating, confined to the outer reaches of Raidho’s Diamond range and well beyond the outer reaches of most mere mortal’s bank accounts. The T in XT stands for titanium-nitride, a development of the white Ceramix cones used throughout the more affordable lines. The “deep ceramic’’ process used by Raidho creates a three-layer structure, an aluminium core sandwiched between thick ceramic skins. It produces a rigid, lightweight cone with good self-damping – for a ceramic structure. Sputter depositing two, thin skins of titanium-nitride on each side of the Ceramix cone creates an even stiffer structure but crucially, one with better, more tuneable resonant behaviour. Combine that with a more powerful motor with twice the power handling of previous versions, and you have a driver that’s more dynamic, more capable, and delivers a lower fundamental resonance. Add a decent crossover and that in turn translates into a speaker system that’s more powerful, more dynamic and delivers more linear bass – but we’re getting ahead of ourselves.

The XT drivers are tiny – a mere 100mm in diameter, roughly the same size as the bass-mid driver in an LS3/5A – so Raidho gives you six of them. That’s six per speaker! You also get substantial outriggers fitted with adjustable feet – a nicety that used to be a (somewhat kludgy) cost option on older Raidho models, an unforgivable oversight on speakers with such long baffles, where rake angle is going to prove critical. Carefully flared slot ports are built into the rear spine to reflex load the bass. One more hangover from the good old/bad old days: the XT-5 only accepts 4mm plugs, although that should have changed by the time you read this. These are classic Raidhos concerning their tall, slim profile, but the XT-5 takes that a stage further, the narrow 140mm baffle fronting a depth of nearly 500mm and a height of 1300mm. That’s deep, tall and SLIM. I’ve seen wings on aeroplanes with lower aspect ratios than this. It also makes for a speaker that is smaller than it looks in pictures and has a lower domestic impact still. From the front, you barely notice the XT-5, from the side you can’t help but see it, but that’s down to the sharply defined and steeply raked profile and the beautiful Birdseye Maple Burl veneer, something more generally associated with Bentley dashboards and super yachts than loudspeakers. The choice of this exotic veneer is both a statement of intent, a small hint of the XT‑5’s real importance in the world of Raidho and a significant contributor to the speaker’s €39,800 price tag. You can always opt for a high-gloss black finish and save yourself €4,500 without sacrificing performance. Or, if you are interested in just how important that titanium-nitride coating is, you could always listen to the X-5, a mere €26,900 in black, a speaker that employs all the same cabinetry and engineering as the XT model, but with standard Ceramix cones. You’ll soon discover that while the X-5 is mightily impressive for the money, the XT-5 is well worth the extra.

Listening to this new Raidho the first thing you’ll notice is their sheer musical presence. The XT-5 delivers all the attacking vim and dynamic vigour of older Raidhos, but now it’s backed up with some honest-to-goodness body, weight, and welly. The bottom end is more profound than you have any right to expect from such a svelte cabinet, but it’s also fast, tactile, and articulate, sure-footed, pitch-perfect and beautifully integrated. As a result, the mid-band has the sort of body, colour, and dimensionality that’s a first for a Raidho floorstander, while still offering the same textural resolution and immediacy that has always been their hallmark.

Listen to Isabelle Faust playing Mozart’s early violin concertos and the XT-5s deliver a real sense of the incredible skill of her nimble bowing, especially hooked up to a really quick amp like the CH Precision I1 or Goldmund Telos 590. But this is where you also get a real sense of presence, scale, and dimensionality, her movement relative to the microphones and the band around her. This is what the XT-5 brings to the Raidho party – and it’s all to do with the when, where, and how of the speakers’ bottom end. Go to the other end of the musical scale – the Shostakovich 5th will do nicely – and the slim Raidhos present all the stark, chill atmosphere of the opening, the shiver in the strings and the doleful chimes, but then they shock you with the sudden weight and impact of an orchestral tutti. This is bass with enough depth and more than enough power to shock and surprise, whether it’s Yuri Petrenko waving his baton or the pounding thunder of the Gravity OST [Water Tower]. But the best thing about it is that it doesn’t just arrive on time, it only arrives when it should. It brings that all-important sense of shape and body to the mid-band, scale and dimensionality to the acoustic, but it does it without slurring rhythms, smudging textures, or dulling leading edges. You get attack, definition, and more than enough weight to impress. There’s no loss of the palpable dynamic impact, immediacy, and rhythmic drive that were always Raidho strengths, but now they are more expressive, more sophisticated, and far more subtle. You often saw older Raidho designs used with integrated amps because they needed the coherence of a one-box solution to help tie them together. The XT-5 works the other way round, taking the performance potential of high-end integrateds and stretching them as far as they will go, actually delivering on the budget esoterica promise. The XT-5s don’t NEED power, but they do like it, so think at least 60 Watts of tubes or a solid 100 Watts of transistors to make them sing.

So, play a great recording and the XT-5s sound great: actually, more than excellent. Play a great recording, and they’ll take you back with their incredible combination of delicacy, nimble micro-dynamics and immediacy, their ability to jump in level and density as the musicians demand it – real “they are here” capability. But that’s not the XT-5s party piece or their greatest attribute. Sounding good on great recordings is smart but not that unusual: sounding good – unearthing the music on indifferent records – now that’s special, and that’s what these speakers can do. Whether it’s the congested muddle of mid-80s multi-mic’d classical, or the average modern pop recording – all ProTools and loudness wars – the XT-5s have an unerring ability to extract every last ounce of energy and dynamic range, every last millimetre of space and separation, every last breath of air from the sonic quagmire. The next best thing to an audio decompression device, they bring the music back to life, but more importantly, they make it fun again. It’s hard to make a case for the sonic quality of Orange Juice recordings, but when Edwyn Collins sings through the XT-5s, you really do wish you’d met a girl like her.
