I hadn't seen your response yet,
@realtight . What were your assumptions going in, and what was your overall takeaway? I'm quite curious to hear your impressions, whichever way it went.
I PM'd the person that originally asked in detail since I didn't want to derail this thread, especially with all the excitement around this new product
So I compared a custom diy JBL 4722n (2225h & 2453h-sl drivers) with the high-end Titan 15. I played them single speaker in mono, level matched with a Harmon curve applied with the ability to instantly switch between speakers as music is playing. I had myself and 6 other people listen blind with a variety of well recorded music.
Going into this I really didn't know what to expect and was a little disappointed that the Titans weren't released earlier because they would have easily been my diy speaker of choice but since they weren't out yet I bought the JBL parts off of another forum member and built custom versions. I really didn't know what to expect going in honestly but I had heard numerous diysg speakers, owning a number of them and building quite a few for friends/family.
Out of the box disclaimer, the JBL's would not be good enough for me without the ability to implement a room curve (like harmon's). They are voiced to be behind an AT screen at a distance much further then a home speaker... if that isn't an issue, then no big deal, if it is the Titan's or any of the diysg offering are ready to go out of the box, requiring no eq.
Clarity: each speaker is very clear with the JBL's being superior. They are smoother but at the same time punchier throughout the frequency range. Top end is airy - similar to a dome tweeter where the Titans are nice but a little harder sounding, can be a little fatiguing at times. JBL has a slight midrange/vocal forwardness which I prefer and often gives the sense of realism that the Titans have never replicated to my ears.
SPL/Dynamics: each speaker does this extremely well, much better then a typical non-pro audio driver based speaker. The JBL still has the edge here as well. Playing movie clips and orchestral music you can tell in my large room that the JBL's have massive amount of dynamics but the Titans hold their own, maybe the dual woofer version would even things out. Bass output was surprising because I had them level matched so that neither's FR had more or less bass but the JBL's stomped the Titans every time. Again the dual woofer version or maybe the 18" might eliminate this.
Soundstage and Imaging: This was probably the biggest difference between them. The Titans just don't do it for me in this category and it might be their only weakness. They aren't in the same league as the Seos 12 or 15 (the biggest of those waveguides I've heard) as far as soundstage, imaging seem to be closer but the JBL's absolutely dominate all of them in this category. It's honestly not even a fair comparison at all. The JBL's can throw a gigantic soundstage while at the same time keep the imaging tight as well. They place sounds into the room 3 dimensionally in ways I've never heard a speaker do before, the waveguide along with the 2453h-sl CD are world class.
End listening results were 7 - 0 in favor of the JBLs. Even the person I built the Titans for liked the JBLs better but they also are/were a Klipsch snob owning many of their Heritage lineup over the years and he absolutely
loves the Titans... I wouldn't hesitate a second to recommend them.
