Personas....7F vs 9H

Audiotroy,
Thank you for your recommendation,My local dealer,audio advice just doesn’t get enough interest in upper model speakers but I’m gonna try and twist their arm to display the 3F.
I really think if they make the investment it would spark more interest in the persona line for them.

If the double basses aren’t my cup of tea,I maybe calling you guys.

I have no affiliation with audio doctor either but I enjoy reading their posts,I think they provide solid info with no pressure and that’s what these threads could use more of.

audiotroy,

Whereabouts do you like to crossover to the JL Subs when you use them (e.g. with the Personas)?

Prof,

We take the Rel approach, we don't recommend any crossover going to the main speakers;

We recomend using the crossover frquency and level controls to bring up the subwoofer to the point of acoutical roll off of the mains. 

Play a bass heavy track and then turn on and off the subwoofer, while repeating the track. Bass heavy should be a bass guitar, standup bass, not electronic.

When the blend is good the sub should be felt rather than heard. A good subwoofer is adding pressure to the leading and trailing notes of the main speakers. 

Tightness of bass is also related to where the sub is located in the room, avoiding corner loanding and keeping the sub on the same plane as the main speakers and moving the subs position also helps to tune the bass for tightness and definition.

BUMP, got to spend a couple hours with the 7f yesterday and am thinking about listing a kidney on ebay, is that legal? The 7f had me laughing uncontrollably for a couple minutes I was so alarmed by the presentation and unless your room is a black hole for bass I expect it would be great. M room is a black hole for bass and I really want that sound I heard yesterday, and I can't afford the 9H.

I have found myself wondering actually what the 7f sounds like particularly since I invested in rather powerful Pass amplification not long ago. The 7f does go down to 25 hz and I know from experience that all you have to do to do room correction on the bass on that speaker is to use a program like REW and a good calibrated microphone, take some measurements, plug in some parameters into REW among which is limiting the filters to everything under 200, 300 or 400 hz and voila, room correction. Just zip the filters, upload them to REW and poof. Another somewhat annoying thing about having a speaker that has a sensitivity rating of 96 db is the tube rush you’ll hear if you have a tube pre, which in my opinion, ALL these speakers could use as a way of softening/warming them up a tiny bit. No tube rush on the 7f and below. Not a biggie but at this level everything becomes a biggie.  And if I keep the 9Hs I'll be happier when Anthem comes out with the almost soon to be released next version of their room correction software which will provide more flexibility to end users than the current version which in my opinion shelves up the bass response ever so slightly compared to the rest of the frequency range.
