It really is a difficult question to answer. Both sound amazing, omega speakers are just darn musical! The single driver sounds a little more pure but are slightly leaner sounding. The 1.5 has a little more meat on the bone but the trade off is, they are slightly less coherent sounding. If you are listening in a bigger room and prefer a little bigger sound, the 1.5 is the ticket. Smaller room, more nearfield, the single driver all day. Either way, you are getting a damn fine sounding speaker. I have the 1.5 and my buddy has the single driver - it really is splitting hairs. The 1.5 offset are killer looking!
Pete, where did you find the balls to fit the SAHO ports? I can only find soft ones that are too large or the right size that are hard plastic?
Bottom Line: there's no perfect speaker.But I'd vote for single driver, 'real' (properly designed) 2-way, or a single driver with sub(s) over a mock 2-way (1.5 way) any day of the week.
Being a SAMHO newbie, I'm experimenting. I plugged the ports. Plugging the ports on the SAMs just made things too thin. But plugging the HOs is magic! I had to do some reading about what happens. Of course there is some differences of opinion, particularly about frequency response. The most common opinion is that plugging just causes the roll off to happen sooner. So bass is somewhat less loud. However the bass that remains is tighter. This is great for me given powered mid-woofers and subs as it makes integration work much better. I think it would work for anyone with just subs as well. Probably best with two.More on point is that it increases coherence. Reading indicated a simple explanation. The port emits sound, as does the driver, of course. But that is two sound sources which causes phase issues. Plugging eliminates that.To me, they now sound like SAMs with better dynamics and bass response. Or maybe I like it as I cut my teeth on the New England sound: AR, Advent, KLH, etc. All sealed (acoustic suspension). I suppose the ideal would be to calculate the box volume for sealed; it is probably a bit different in required volume than ported. But it is working beautifully for me.Anyone else tried this, or care to try and report results?
People who haven't listened to Omega single driver or 1.5 way designs should really not speculate on how they sound. You do a disservice to AC members trying to make a tough decision without the benefit of them being able to listen with THEIR ears.HK
Yup, the big advantage of a .5 way design whether it's 1.5 or 2.5, is the drivers sound the same because they ARE the same. One of the big reasons single drivers are coherent has NOTHING to do with phase or point source or crossover... it's because multi-way speakers often use drivers that don't sound the same. I can take the exact same speaker and by changing nothing but the diaphragm of the tweeter in question, go from a speaker that sounds incoherent and somewhat disjointed to one that is seamlessly integrated. Without changing the xo, without changing anything about the phase/time relationship, without point-source, etc... it's simply that one driver sound different... .5 way solves this issue.
