**** I do not own the speakers pictured below, the images are from a offer i have found for Qe's ****
First off, i am looking into getting into the large 12" infinity speakers, and i am saving up for one of the IRS series. The smaller speaker is only to bridge the gap between now and the time i get the IRS Speakers + amp. Also another reason is, i am reasonably sure that a infinity speaker in the up to 200$ range will outperform my current (originally 100 euros) speakers with some slight mods, and new tweeters (i kind of sort of broke one, somehow).
I have no doubt that the Modulus is a very good system, and i am currently considering getting them for my Desk setup (after i have the IRS) but the prices on them are insane. I found some locally for 700 euros a piece, and that's a tad bit high for me at the moment. But i am liking their design, very impressive! I also find it interesting that the woofers look a lot like the woofers on current Klipsch speakers.
My main listening room / bedroom can just about handle a IRS gamma in terms of size and SPL.
I have also ripped the images of the Qe from the online offering to see your guy opinion, according the the seller they work.
So basically based on all the posts so far: Get the Qe if you can get a good price, and upgrade from there.
