I agree with Aball. Even Alto Be will be probably too big for your room. I audition Alto in room 20 by 14 and they overloaded it in midbass. As I said in one of your previous thread decision is a tough one. Maybe new Electra 1027Be could be a solution? It is very nice looking also( WAF!) and price is $7500/pair. AP Avanti 3 is not in the same class as Alto, it can be compared with Diva but, if you like Focal house sound I am not sure that you will like Avanti 3... Important issue here is you room. Will it support Alto Be? Electra 1027Be will work in your room without problems( I hope) but, will it better Micro Be in overall sound quality? If Altos can work in your room then they are the best choice( even if you need to buy them on second hand market ). Altos go to 25Hz(-6db) in-room so they will give you deep bass that you are looking for.
UNDECIDED UTOPIA.
I have put forth a few post lately regarding floor standing speakers in the crowded 10k range. Living in a rural area of the US precludes my listening to speakers before buying, so input from Audiogoners is critical. I have my choices narrowed down to two or three speakers that are WAF certified. As I have JM Lab Micro Utopia Be's, I think it would be a safe bet to move up the line to the Diva or the Alto. On paper, both of these speakers have specifications very close to each other.The Alto's would be a stretch both for my pocket book, think used here, and for my space, think limited placement options here. The other speaker is the Audio Physics Avanti 3. In talking to two dealers that carry both lines, both have stated that they preferred the Diva to the Avanti 3 by a wide margin. However, I would love to hear from Audiogoners who have owned or extensively listened to these speakers. Room= 14x14x8 in a square with a small open passage leading to vanitys for a total of around 210 ft( Master bedroom). It is important for the speaker to sound good or full at lower volume levels, and for the speaker to have really good bass extension. I will not have room for a sub woofer.The Diva's and the Avanti's are similar in specifications, with the Avanti's having a slightly lower specified bass range. However, several dealers have stated that they felt the Diva's to have better bass. Listening tastes=instrumental Classical and Jazz( From orchestral, chamber, to solo). Gear= Bryston 4B-SST amp and BP-26 pre-amp, with an Ayre CX 7E cd player. Sorry for the length of the post, but at this price range, I can not afford to get this wrong.
