Elac Uni-Fi UB5 Review

Elac Uni-Fi UB5 print size, two-way compact producing a big, hearty sound for a reasonable price tag makes this speaker a big hit on the market, winning the hearts of high-enders and mainstreamers.


The UB5 is a stand-mounted compact with a bass-reflex design with a rear-firing dual-flared port. Being thirteen inches small, it’s one of the smallest three-ways ever made, all because of the concentric driver’s remarkable space-saving properties. Elac’s new speaker range is slimming physically, not in its glory, as its speakers carry a little less weight than most speakers. Having that in mind, the Uni-Fi BS U5 are indeed slim speakers. It’s like Elac has taken its Uni-Fi series and thus added some more elegance to their design with their tiny proportions and the satin-black finish.

It has a sophisticated design that insets a one-inch soft-dome tweeter at the center of a four-inch aluminum midrange, with a crossover point of 2.7KHz.Except for some minor trim changes, it is similar to the B5 with some added finesses, like premium binding posts and a magnetically attached fabric grille. We are talking about a sturdy MDF-braced enclosure that adds a couple of inches. The finishing touch, like the Debut line, is black brushed vinyl.

Sound quality of Elac Uni-Fi UB5

In a way, if you like the B5 as an enthusiastic audiophile would, you are going to love this one a little bit more -it’s like the UB5 is the UB5 going to finishing school. It has fewer box colorations and smoother, more accurate tonality, giving greater output and dynamics that befit a three-way design. It does come off a bit dry in the treble but decently detailed and not offensive. In other words, it’s everything that the B5 already is, with a few more extras! UB5’s voice, in a musical sense, is the B5, or the Pioneer SP-BS22, or even TAD-CR1!!! All of the examples above share a similar overall voice, anchored by a dynamic, balanced midrange, forward energy, and a transparent lower midrange and upper bass.

When talking about the UB5’s dedicated woofer and concentric driver, one must keep in mind that two issues stand out-, the first one being the point-source-like coherence that the coincident created. In that manner, because the coaxial structure makes a near-ideal time alignment, the experience resembles a single full-range driver and the two transducers operating with their specified frequency ranges, which causes a massive improvement in output, as well as in dynamic payload, with less distortion. Compared to the B5, there’s added specificity, steadiness, and focus to images that are the concentric driver’s trademarks. Bass quality is the other most notable improvement- there’s a solid fifty-cycle midbass output similar to the B5, although much more controlled and less depending on the port. The timbral definition does become a little bit woolly, but the crucial low-end energy compensates for this minor issue.

The concentric driver allows excellent cohesion between the mid and high frequencies, although the bass comes off a bit detached from the fold below that.


To the UB5’S credit, an audiophile can easily compare it to far pricier speakers, like the excellent KEF LS50, the Revel Concerta2 M16. In that sense, given its price tag, it should come as no surprise that the UB5 has a couple of weaknesses. Transparency was quite perfect for this segment, although there was some veiling present. The UB5 doesn’t shed its bounds – the cabinet doesn’t disappear like those of some more expensive small monitors do.

Indeed, for this price, you can find more than a few options on the market, like Dynaudio leading the way with its transparency, precision, and authority.

However, as you already noticed, a lot can be said about this one – especially for a trim, good-looking pair of speakers that are open sounding, fast, agile, and energetic, and can play ball near a back wall. In that matter, if style and looks are what you are opting for, meaning it stands tall on your priority list for new speakers and music equipment in general, then the Elac Uni-Fi UB5 Slims is an excellent shout indeed.
