Kunja, where are you located? Are there any Cain & Cain dealers in your area? It would be worth listening to the Abbys - they are big and difficult to transport speakers, although in your room they occupy a small footprint. You can't really go wrong with them if you are looking for a full sound.
Sorry but never heard the Lowther in questions. Another alternative often mentioned here are Bob Brines speakers, which are not quite as pretty as the Abbys and I don't know of anyone who did compare them directly to the Abbys. Lookswise there is no question though... Again in your pricerange the Horn Shoppe Horns seem like a good option too.
Also, one last comment: Single drivers do require a careful amp match. The Fi X/Abby combination is excellent, so is the First Watt F1/Horn combo in my own experience. Furthermore, single drivers are not for everyone, some people just can't live without the top end or bottom end extension. Worth listening to a few or at least buying some on trial.
