I was listening Evo 4.4 for some time, upgraded them a little. Then there was opportunity to get Aura 3 second hand, but new in fact. Even spikes were not unpacked. So, they are mine. Compared to Evo they have more articulated base, more involving and clearer mids. Just more powerful tweeter, harsh some times. Compared to Evo’s where highs are detailed but gentle. Aura's tweeter sometimes be like "Hey man, Look at me, I'm a big AMT!". It's good for my 20sq.m. room that I can place Auras just in front of the wall (manual says from 5cm!) and they are not becoming boomy compared to Evo 4.4. That's all that I can say for a week of listening. Don't have any measurement equipment so looking forward for someone to measure and review them.
But let's look inside!
First, removing rubber trims.
1. Cabinet.
- On a positive side is its weight - brochure says 23/25kg net/gross but in fact they are 28Kg! It's pretty solid but have a thin plastic port tube which I already covered with auto noise reduction material. Strange! One cabinet have a lacquer inside, other just opened mdf.
- Spikes are gorgeous! 2 kg of steel! But can't understand what are the holes for.
- Again a big plus(spoiler-not much sense) - all drivers attached with 6 bolts each to metal inserts on a cabinet.
- Unfortunately there is a fault and engineer mistake - drivers attached with bolts but thrue plastic chrome rings - so you can't tighten them properly before cracking this rings. And can't understand a fuss about rubber rings - they are just covering bolts:
- Damping material. Once again a mismatch from official pictures. It's some kind of synthetic felt instead of foam. Material the same as in Linton, Evo 4. Packed very tightly, 5 mats in total:
- Fire in the hole! Chamber for mids is made of carton and working as brace also. But hole for inserting wires for just punctured, not drilled. So big ugly hole with with pieces of peeling cardboard from other side, surrounded by some viscous substance. Changed it for sealant.
2. Drivers.
- Tweeter. AMT with metal frame and plastic chamber with damping mat in it. Everything looks OK. Just not happy with holes for wires. I've added a little sealant, just in case.
- Midrange section. Oops - plastic frame. Why? Manual and website states that it's metal. In a good side - motor is ventilated.
- Bass drivers don't have ventilated coils but have a aluminum frame.
3. Electronics.
- Wiring. Exactly the same wires as in EVO series (some Chinese OFC). For EVO they looks good, but for price of Aura... a bit thin at least. Wires are not attached to cabinet, not glued, so I redistributed them a little, puncturing damping mats.
- Terminal posts. Again, straight from Evo series. Plastic is really thin and arches when tightening screws.
- Crossovers. They are huge and separated for mids/highs and woofers. Thanks for polycaps, but cheesy resistors. Noted that crossovers located just behind woofers and can resonate. I've added some damping pads.
So what do you thing of them? What are their competitors on a market?
