Sub matching...REL with Klipsh

I emailed them once and they said pair of t5is. I emailed them again a couple weeks later and another person suggested t7i. So
..I sent a 3rd email recently telling about the first 2 emails and asked for a tie breaker. They don’t have klipsh as an option on their subfinder so that’s why I had to email. In regards to klipsh rp600m...ive had people tell me the t5i will be a waste of money and to get t7i and I had people tell me the t7i will be a waste and that t5is will intergrate better. I think with the room size I have either or will be ok. I do understand the t5is are limited but I dont think I’ll be upgrading my bookshelves anytime soon. If I do upgrade things will probably be set up in a totally different space where maybe a t9i or another brand even would be a better fit.  If your interested I can let you know what they say for my tiebreaker.

The REL T7i should be a great match for a room your size. They should run pretty flat to around 30hz in that space. Your speakers are quite efficient, but the T7i should have enough gain to match them. Your speakers by themselves should be able to reach down to around 50hz if positioned properly in that room. 

I respect RELs honesty with your speakers. Shows they are not just wheeling and dealing. 
I do remember watching a video about that upgrade to the rp600ms. I'm not 2 confident in my electrical tinkering skills so I'm going to have to watch it a few more times and see if it's something I'm comfortable doing. 

 I will be going with REL.

 Why?
You don't have a problem yet.

If you can go  with two T7i's then by all means. One is never enough, even in a phone booth. Rel's instructions on how to set up their subwoofers is designed purely to eliminate expense and make it easy on the inexperienced and that is fine but for optimum performance there are better ways to do it.
