Hi gang, thought I'd chime in as several questions have been raised in this topic that I can address.

First, Invisa speakers are very much just like their non-in-wall/ceiling counterparts, for the reasons indicated. The HTR and MPX are the two models that parallel the box speakers and are designed for high-end home theater and music applications that require in-wall or in-ceiling. The HTR is essentially an Aon 3 without a box and passive radiators, the MPX is similar to a Triton Seven, again, without the box and passives. Setup properly they sound amazingly similar to their counterparts ... above 100 Hz. More on that below.

In-wall and In-Ceiling speakers' bass performance is dependent on the wall and the enclosure. Regarding the wall, stud/drywall walls do not support bass below 100 Hz in a fashion that will appeal to the audiophile. Just let all the BS about "stiff chassis and metal boxes" go by. That said, the larger the enclosure, the deeper the speaker will actually play - and a full stud bay (or ceiling) is a big enclosure and will allow great extension (as evident in the specs), albeit with somewhat limited power handling at those lower frequencies. Add a back box to limit audio bleed or put in a smaller enclosure, bass goes bye-bye. And keep in mind that none of this matters because no one is going to use these for full range, serious listening levels playback - for that they need to be crossed over and used with powered sub(s) to complete the package and achieve the desired performance. And that's a good thing, because there's no comparison between the Invisa bass you get and the critically engineered system-bass you get from an Aon 3 or a Triton Seven (or any other of our full-range models). More on this below.

Regarding bass measurements (keep in mind that I, and Sandy, hate measurements ... listen to the darn things and don't look at the specs ... PLEASE), we have found that the measurements reported by almost all the various review magazines are simply incorrect and do not correspond to actual results in-room (or the results of their own listening experiences, as reported in the reviews). This is because of the nonsense bass measurement techniques that try to near-field measure all the bass drivers and them mathematically sum the results (with some arbitrary formula) to achieve a reported result for bass extension. Extrapolated anechoic measurements are better, but not many have access and not many chambers can actually measure ultra-low frequencies because they are not big enough. So what matters? How about in-room response ... the actual bass you can measure in your room, with a calibrated microphone and an appropriate measurement program. Somebody mentioned the Aon 3 in this thread, which I personally measured in my room as flat to 42 Hz. My Triton Twos were flat in my room to about 24 Hz. Haven't measured the T1's yet in my room but there is no doubt (sonically) that they play lower than the Twos. In my experience, these are simply extraordinary numbers for full range speakers (not to mention ones that start at $800/pair).

Hope this helps.

Moderator,

Thank you very much for joining into the discussion and sharing your expertise! Hopefully this will provide meaningful feedback for members to help them make a decision on the Invisa series speakers. I, for one, am sold and plan to use them as my Atmos channels. The fact that they essentially have the same drivers as my Aon 3s tell me everything I need to know.

When shopping for speakers this last year, I relied on both objective and subjective information to help me decide that GET's line up was the right one for me. I believe that objective measurements can get you in the ballpark and prove good engineering. ALL of GETs objective findings during professional reviews have been very good and support the work that you are doing at GET. One thing objective measurements won't do is tell you if you are going to like the sound. That's where reviews by product owners and professionals, along with personal auditions, will best serve people looking for new speakers. Nearly all reviews of GETs products further support that they are fantastic.

I understand your points and agree that measurements can be misleading and should not steer purchasing decisions but what they can help with is equipment set up and integration. It is extremely helpful to know where to start with crossover settings and this is where some objective measurements can help. I can only assume these are where Sandy's tips come from as well. These tips have been extremely helpful for me in fine tuning my set up. I certainly agree that the objective report that states the T1 will go down to 30 Hz before reaching the -3 dB point inaccurate. I have felt my T1s go much lower and I say felt because I could feel the bass and not hear it. This tells me it is reaching down to the 20 Hz range without breaking a sweat.

It sounds like the installation of the Invisa speakers is a little more difficult to estimate frequency response. My installation will be in false ceiling with a lot of open space. I doubt that I will be reaching too far below 100Hz with this application but that does not steer me away from the HTR 7000s. Having the same drivers as my surrounds is enough to convince me they are the right speakers for the job. I can always try to figure out some sort of enclosure in the ceiling cavity if I feel I need additional low frequency response.

Thank you for humoring our discussion and providing your technical expertise, as well as, corporate knowledge. I'm not aware of any other speaker manufacturer that provides as much cohesion across their product line as GET. I can't think of a better brand to use as the foundation for a home theater! Combine this with the excellent stereo capabilities and all with a price that the other 99% can afford, and it's a slam dunk IMHO.

Cheers,

T Cobe
