You must be referring to the two members who said their FV15HP's don't flex like mine after watching those videos? I captured the videos because there just aren't that many out there of the FV15HP in action and I wanted to show just how much throw they have because I think it's pretty cool looking. I also wanted to show how the drivers just stop on the dime. Like I said before, definitely way more noticeable with the silver cones.

Receiver - Denon 4311CI
Speakers - Infinity P363's, PC351, P153's
Subs - Rythmik FV15HP's

Thanks for the kind words!

For sub placement in general or for putting subs flush with the mains?

In this case neither choice has anything to do with sound, it's all about where I can place them and aesthetics/cosmetics. For placement, there's a (the) door where I'd like to place one sub, and there's not enough space on the other side of the room between couch and wall for the other sub (it's a bit narrow). Vexing, as I could really use them there to help compensate a null. My room lost about a third of its volume (and nicely primed dimensions) when we decided to add a bedroom downstairs. The bedroom is/was much enjoyed by my younger son, and undoubtedly provides greater resale value than a larger media room, but I'm still bummed. One of the reasons for getting Rythmiks was the phase adjustment that would make it easy (easier, anyway) to place them where they'd do the most good vs. where they look best.

Brian will eventually benefit as I plan to get a couple more F12's and place toward the rear to help reduce those pesky nulls.

Placing subs flush with the mains, other than for looks, does not make much sense to me. The wavelengths are huge and most towers have woofers at the bottom so reflections are a non-issue (unless the subs are at ear level and causing the tweeters to reflect off them). I do it for looks just because it makes the front line (Maggies and subs) look nicer. Also one less thing to trip over.

My comment on reflections was meant to be general, e.g. don't put a big reflective boundary next to the tweeter at ear level, and not sub-specific. Long week, forgot where I was posting.

I've put in 80+ hours the past few weeks, new chips got back and aren't working quite right, aarrgghhhh... Should drop down to normal insane hours soon. I need some sleep, got a lot to play in the next few weeks and haven't had much practice time. Going to put my system to use this weekend to listen to a couple of versions of "Planets" (playing it in a few weeks and want to see how other principals did it) and watch the last Hobbit movie.

On topic: I lost my link to Toole's paper on multiple sub setups, anybody have it handy?

Thanks - Don
