First time posting.

I recently auditioned the FV15HP at a friend's home theater...Wow!!! I have been shopping/researching for my new 7.2.4 HT and I think I found the first 2 pieces (dual FV15s).

My room is 9'5"H x 15'5"W x 24'3" L. 2 rows of seating (not yet decided on distances). I only care about the 1st row two middle seats.

Use will be 100% HT, but a fair amount lot of Music Concerts video content, not just movies.

1st Question: Should I go for the Raal versions of the Tower and Horizon? Or is the benefit negligible for a 100% HT use? I wont watch movies/concerts at a super loud level.

2nd Question: Assuming I get the Tower/Horizon Front Mains combo (no raals) to go with 2 FV15HPs. What would you recommend for the 4 Surrounds and 4 Atmos/Height speakers? Would like to stay under $2000 on these 8 speakers. My preference would be for Inwalls as I like the flush look of a HT.

I will be using either a MRX-1120 or a Denon 6500 as the receiver with no separate Amps.

Appreciate the responses/suggestions in advance!
