For the review, since you have the full floor standing Otica, I'd like to see impressions of the Otica by itself and the Otica with the servo subs. If you only do one version, do it with the subs since these speakers are intended to be a full range 4 cabinet design ( 2 cabinets Oticas & 2 cabinets servo subs) like the Infinity IRS speakers.
In addition to your views on the performance of a speaker, I also like your input on what it takes to set up and dial them in, strengths and caveats, as well as general impressions of other people.
If you do sound demos it's important to remind viewers that what they hear is not going to be the same as what you are hearing, especially if their systems are not as resolving and/or as capable of reproducing the low bass as the Oticas and servo subs. What someone hears is more a function of your recording, YouTube's transmission, and the viewer's system than what the Oticas/subs sound like. Bottom line would be they sound better in person than what they sound like over TouTube.
To piggy back on something Jay said, let people know that just because the speakers are DIY doesn't mean they are out of reach for anybody. A person can do as much or as little of the build themselves as they want to. Their options range from doing everything themselves all the way up to having someone else do everything for them and ending up with a fully built and finished turnkey set of speakers. In other words, they can do as much or as little as they feel comfortable with.
As soon as they hear the speakers are DIY, a lot of people are going to think "I don't have the ability to build something like this so they are not for me" and tune out the rest of the review. While the more someone does themselves the larger the bargain will be, even if they have someone else do all the work they will still end up with a lot more speaker for the money. Also, there is a lot of help available through the forum so it is not like they buy the kit and are on your own.
