I have a full 7.2 in my basement but i keep the door closed, so the cats don't get in so they don't bother the grills. In my family room, I'm using bookshelf DefTechs, which they can't reach. But Maggie's are grills on the floor full time. Does anyone have cats that are not de-clawed and how do they deal with this other than de-clawing or getting rid of the cats -neither of which is an option? I have. Cat tower and lots of toys and that will help. Is there a cat "guard" anyone has used that doesn't affect the sound? I don't want this to be the reason I don't buy these speakers. Thanks!
I bought two artificial fern plants in baskets from Walmart and placed them on the floor in front of my 0.7s. They are wide enough to extend well beyond the sides of my Maggies and short enough not to interfere with the sound. They are stiff enough to discourage our (fully clawed) cat from approaching the speakers. So far, they appear to be working purrfectly, as the cat has shown no interest in the speakers for the 3 weeks I have owned them. My 0.7s lean backward at angle, so I have not felt a need to put anything behind them. I believe the 1.7s stand vertically, so they may need a plant behind them as well as in front. YMMV.

At Amazon, search "Scatmat" when placed around objects discourages approaching animals.

You could also temporarily surround the speaker with a fence of chicken wire.

Any Maggie .7 owners out there with a sub, no bass mgt, and your mains running full range? If so, I'm curious what low pass settings people are using. I just got a JL Audio D110 and did a rough preliminary setting by ear and have the dial at around 55Hz as sounding the best after about half an hour of playing around. I wanted to see how this compared with other owners' setups. I need to eventually buy a measurement mic and do a more formal setup, but that will be later.

Not a .7 owner (very nice model, btw), but that crossover seems about right to me, especially since you’ve spent a little time trying out different crossovers. I use 40 Hz crossover for my 3.6 since I want to hear the bass from the panels and use a sub for what the Maggies can’t reproduce loudly and clearly. However, this is a music only speaker setup and that’s why I crossed it over so low.

I'd recommend keeping it where you have it, until you get use to the sound. Then use a different crossover and spend some time with that. Kind of a "rinse and repeat" method that I've used.

I cross my "bass managed" 1.7's at 55Hz also. I've tried many times to run my 1.7's full range with no sub and I was not completely happy. I've tried many times to run my 1.7's full range with my sub (Rythmik F12) and I have found 40Hz as the best crossover point. I was, however, never completely satisfied with the result. I missed the "concussive impact" of drums and the "acoustic weight" that the bass managed 55Hz brought to many instruments. More subtly the bass managed 55Hz brought "soundstage weight / volume / and soundstage size" into play on those recordings that featured a large natural ambience.

I will say I spent a lot of time getting the phasing dialed in between my sub and the 1.7's. I highly, highly recommend spending as much time as possible making sure you are phase correct before fiddling with your crossover points. When I finally got it all "dialed in" the "air" in my room began to "beat in sync" to the low frequency tones when playing sweep tones 60Hz down to 30Hz, and below.

I have the Hi Rez download of the Paul Simon "Graceland" Album. I cannot remember the name of the cut .... it is the Vocal Acapela piece, (I will name the cut as soon as I have a moment free from work to jot it down). The studio "room tone" on that cut has an extreme low frequency air conditioning tone that was never rolled off. That tone has such weight, and it is at such a low frequency, that you can clearly "feel" the volume of the studio "weighing and pulsing upon you". If I change the phasing of my sub just a tiny bit you completely lose the "tactile feel" of that tone .... yet you continue to hear that tone clearly. Adjusting the phasing back to the "sweet spot" the tone immediately envelopes you .... almost touches you ..... you feel it ..... it's is unnerving.

I know that I am not exciting a particular room resonance or node because once I am in phase, all musical content at all frequencies below 60Hz exhibits this effect. In short, when my system is in "perfect phase" bass has solidity, the attack has a unified wavefront, it is capable of enveloping you in tactile peaks and troughs that correspond to it's frequency. When even slightly our of phase the bass sounds great .... but does not "touch" you.

Concerning our Mains: It's not like I am comparing apples to oranges ..... our Maggies are fairly close cousins .... maybe more like tangerines to oranges!! I just think it's interesting we both settled on the same crossover frequency. Our Subs ..... I don't know what t say ..... except .... they're different???

So polecrab enjoy your fine sub and mains, take you time fiddling and adjusting, and always remember to enjoy the music and not the "tones"!!! By the way what is your amplification and the rest of system??

Thanks for the input dsrussell and stustan. That gives me some perspective. Stustan, it's interesting that we arrived at the same 55Hz crossover, but since you're in a bass managed situation, your 40Hz low pass with 1.7s running full range might actually be more applicable to my situation. When I dialed my point lower, like in 40s, the midbass was cleaner but the impact and weight of kick drums was missing. I settled on 55Hz as a good compromise between bass power and overall clarity. I positioned my sub much closer to the listening position than the mains to give me a better baseline to adjust for group delay and phase, which I hope to do with additional equipment and software later. I want to make sure not only that the subs are in phase but that the initial impulse is also in sync, and since I can't delay the mains signal, I have to start with the subs either early or in sync. I'm driving my Maggies with an ATI AT1202 and using an Oppo HA-1 as a preamp. I wish there were more options in this price range for 2.1 preamps/integrateds with bass mgt, so I had to just throw in the towel and do without it. I was considering the miniDSP, but my Oppo has so many advantages in terms of features, usability, and connectivity, they outweighed the bass mgt for me. I can still do room correction at my computer source, but unfortunately I won't be able to control the sub separately from the mains. However, even after a very crude, half hour setup by ear, I'm enjoying the sound of the subs, and having fun playing the Mahler 6 last mvt hammer blows, etc.

I found through the years that 50hz is the best all around setting, usually prefer a 24dB slope. This all depends on your subwoofer performance /traits. There are lots of rather anemic subs, major brand names that have no capability to reproduce actual "sub" frequencies, and bottom out easily when asked to do so.
I just wish I could find someone local to audition a pair of 3.6 or 3.7's. Magnepan used the 1.7 with the 2 end tables when I heard them at T.H.E Show 2 years ago.

Earth: The Insane Asylum of the Universe, nowhere else could things be this screwed up.
