I use since September O300D qq years in a room of 60 m2 Fully dedicates trafficking in the region of Besanon. HomeCinema HiFi and use. This is only for the cost because I am not a homestudiste.

The O300D are fed directly via a sound card in Lynx2B symtrique. No pramp.

Distance costs: 2m40. This is the max that Nearfield near midfield and are able to cash in a properly damped acoustic if you want to keep a dynamic subjective crdible in the medium-high.


Like any pregnant irrprochable quality, the O300D is dependent for its Fully made of coupling with the room in which it is established. If we accept this to work, the O300D will render Specifies the height of these (see measurements on the site of K & H) c - d. exceptional full range frequency drives (except the point just BMOL APRS) and therefore capable of reproducing any of Manir convincing small and large training properly recorded (hello in passing to the studio Passavant my region which j'apprcie bcp the quality of production ). However, as with any instrument "sharp" and rgl at the factory to be the + neutral as possible, it is very easy to record his highly DGRAD if the environment is not the height (all as a formula will have a bad behavior on a country road irrelevant).

His only weakness: the curve of max SPL breaks quickly figure below 150 Hz (210 mm woofer is no miracle and can not send the max, 90 dB SPL 40 Hz). It means being asked Obviously ds rendering a less demanding in terms of dynamics in the bass (drums recorded with uncompressed dynamics, for example). We note in passing that although the rev limiter protgent pregnant vitent well runs of distortion. In short, a product made to last even in the demanding conditions of use trs.


In terms of the evolution lends itself well O300D an association with 38 able to climb high enough and therefore on the steep trs O300D cut to 140 Hz (filter numrique board. Doing it relieves the 210 mm high and the bass and amp power supply monitor, which seems at once absolutely tireless. With this approach, we can get a nice dynamic 2m50 up frquence of the So about 40 Hz is a product which can consider buying in a spirit scrolls. Otherwise, it will probably fall back on the new ø410 of costs which should ralistes up 3m50 (? ). But the budget is Different.

How do you report qualitprix?

In my opinion, it is correctly positioned the product as a no-fault had kept his design (with 3-way nearfield woofer 210mm)

Exprience with, you will do again this choice? ...

Without hsiter. But impractical choice coupled with a good sound, otherwise the weak link is the acoustics.
