HT: Has anyone ever moved from high sensitivity speakers BACK to low sensitivity?

After receiving my QSC K12 and comparing them to my old monitor audio RS6 i cant believe what ive been missing out on... having a speaker that can hit peaks of 120-125db in my room is a totally different movie experience.


My room is 19x13' sealed.


The question is if anyone has ever gone back to low sensitivity speakers in their theater after hearing high sensitivity? and why?


Im going to go out on a limb and say that the only people with low sensitivity speakers in their theater have never heard high sensitivity speakers or require high WAF. or maybe their room is 12x12

I am very interested in Yorkville. My next pair of speakers will most likely be those, AudioKinesis Prisma, or Soundfield Audio dipole point sources. All high efficiency designs.

Also, Toole only recommended horn loaded speakers for very large rooms.

Toole is partial to speakers flat far off axis, which precludes constant directivity designs from his theories. Much has changed since then. For instance, I don't believe this was taken into consideration. It's a game changer.

With all the comparisons being made in this thread, I'd like to point out that those fared well against the GedLee Abbey and Nathan, music and movies. Comparison done by someone who owns all three, and kept all three.

Another hoarder like ATDG. It's an addiction I tell you. Wait till the TV crew shows up at ATDGs house for a "rescue".


General clarification, Unity and Synergy both Danley, the former licensed or designed for Yorkville.

The 1812s?? Bipolar (asymmetric/variable) point sources. Dipole (asymmetric/variable) bass only.

And ya better start saving yer pennies.



cheers,

Home Theater system, Abbey L/R, Nathan center, SHO-10 surround duty. Owner did try the SHO-10 as mains for comparison.

Yep, Mr. Danley's creation.

I thought the top was dipole, too, at least the 12" driver. Hmmm... interesting *strokes beard*.

Wait.....did you just say the $395 SHO-10 compared well against the $3,000 GedLee for music?

No surprise there. By the look of it they use an Eminence pro-sound woofer, probably the Delta 10, and when you limit the low frequency corner to 80Hz as they do you can get a very good result for very little cash.

thank you for the Pi white paper link. a lot of good info for a newb like me.


their arguments against symmetrical horns seems very convincing. I am curious where CHT's current 90x90 horn falls in this respect.

I have had many good lower sensitivity speakers but tend to prefer CBT arrays because I can get both excellent sound quality and high output plus large dynamic capability. My earlier experience with straight (conventional arrays) always had me going back to arrays because of the lack of compression. CBT's sacrifice some of the output of a straight array but offer better vertical coverage which surpasses anything else in arrays or conventional designs (a big advantage for theaters with tiered seating).

It is just a design choice that Parham has made. The GedLee oblate spheroids are 90 degree waveguides, I believe.
you are absolutely right, all of his speakers use 90 degree waveguides.

I just got a word that my set of SHO-10s is delivered.

The woofer also has a uniform radiation pattern, so Earl's thought is why have the HF and LF sections different? In truth it doesn't matter that much on the vertical plane, whereas having similar horizontal dispersion at the crossover frequency is. You can get that result with both HF section types.

So is thetre any validity to Pi's narrow front lobe in symmetrical horns reasoning?

I'll keep my 104 dB Klipschorns, thanks. They do music very well.

Ditto on my 1979 Klipsch Cornwalls(real wood cabinets) we purchased new. 102bd 1watt/1 meter. The Heritage Series Klipsch sound a lot


different from the newer towers they sell now.

Maybe, I lost interest by the end of page 1. Brevity is not only the soul of wit, it also keeps your audience awake.

here is the relevant page...there is also a video on their site about it.
IMO much ado about not so much. Wayne and Earl both stand foursquare behind the type of horn that they sell, surprise surprise. Should they both show up here to debate their positions it would go on for days, if not weeks.

in my situation, and I suspect this is fairly typical, vertical directivity is not that important because my speakers are on-axis in vertical plane.


this maybe a valid consideration for side surrounds however

There are lies, there are damnable lies, and there are statistics. In this case substitute 'charts' for 'statistics'. The lobing shown on that chart is at a certain unspecified distance. What it doesn't show is vertical polar response at a typical listening distance, where said lobes would probably have disappeared. As with statistics charts can be configured to reinforce a particular point of view.

So you don't hear all the floor and ceiling reflections (axes) and the total radiated power summation doesn't change the total tone, timbre, etc. perception at your ears?

Interesting room you must have.

Oops, bad choise of words. Sure vertical directivity is very important. I meant to say that off-axis vertical nulls is not an issue in my case.

Good point
