SOLD: Omega Speaker Systems Customshop 8 HO Monitors
anyone make something like this ?
omega website mentions 200hz...………………
"Stop scrolling and check out these sweet monitors now on sale at the Omega Store. Feast your eyes on the Vintage 8 High Output Monitors finished in curly fumed oak. This absolutely stunning pair features two of our very own 8 inch full range drivers in our high output configuration. What does that mean? It's a no compromise design by which you enjoy all the accuracy and holographic midrange of a full range driver with an identical (sans the whizzer) driver cutoff at 200hz for added bass and dynamics. The bottom-ported design reinforces low end even further for a speaker that's perfect for whatever music you throw at it. It's all you could ever want. Plus, these speakers deliver very high efficiency so you can make them sing with only a few watts. The cabinet for these monitors was modeled after classic speakers like the JBL L100 and fits perfectly in these Deer Creak Audio stands (included). Did we mention they're hand made right here in the USA? We're blowing them out this weekend at a low introductory price. Don't miss your chance on these! Order today! Link in the bio."
200hz seems a squeak low for baffle step, but I remember an old Klipsch pdf where a heresy was taken off floor (wall / corner ?) and placed on stands, bass below 200hz really nose-dived...…………….

Imo a bit silly.
Seems they have one chamber for two different drivers with probably very different characteristics, the chamber is also probably slightly on the small side for double 8". Doubt the tuning is halfway decent.
Might be fun, but with that kind of wizzer it's probably needle-edge hotspot + knife edge sweetspot just outside that. I've never heard them though, so I *could* be wrong about that.
They are probably reasonably efficient, so claiming they're "very high efficiency" is not completely off the mark.

Speaking from memory (so under correction), there isn't a vast amount of difference in the electromechanical spec. of the two Omega drive units. One is sans whizzer and likely has some other structural modifications as it's used as a compact broadband woofer, but otherwise ~similar enough to be classed as a near-equivalent for alignment design. Theoretically you can use dissimilar drivers and fake up a compound spec. for LF design purposes although the closer the drivers are the better; large variations e.g. significant size differences aren't a good idea or one will start to modulate the other.
WRT baffle step, assuming a 14in wide baffle then nominal anechoic F3 is about 308Hz, give or take. In practice it's likely a touch lower; with a floorstander you might get a significant reduction but as they're standmounts that's unlikely to apply. Assuming a nominal 200Hz per claimed, potentially should balance off reasonably in practice.
Not having any specs. or heard them, I can't comment on the alignment & general behaviour otherwise.

the late Brian Cheney (VMPS) mixed "whatever" in one chamber and that worked quite well in the bass 😀
I ask because i may end up with an extra 8" full range.
So instead of a fern & roby raven, make more of a 1.5 way with 8" full range drivers.
200hz f3 baffle step into 8ohm would be maybe 5mH (memory) ?

If I where to do that, I'd put the 8" FR in a sealed chamber, and a separate chamber where I had two 8" in some sort of ported solution. Partly because having speakers on stands is a waste of both potential and money IMO.
Edit:
If it was because I had too many of a specific driver, I would make an angled front so that the drivers pointed in different directions.

About 6.37mH but that's assuming a stable impedance. At that size / frequency it will almost certainly interact with the upper box impedance peak & cause a rise in output at that point, so unless you want to stamp on said box peak with a high value input LCR Zobel, you'll probably end up needing a smaller coil to pull things into line.
If you've a pair of reasonably similar 8in widebanders, no real reason they can't use the same volume if you design the alignment with a compound set of T/S values. If the drivers have significant differences I'd be a bit wary of that approach though, so isolating them in separate sub-chambers would be favourite under those conditions.

Hmm, i have FE166 + a pair that have lost their whizzer. Takes some work to get bass out of but you could take the same approach. 2 good whizzer FRs, take the whizzer off one (you will likely losose the dustcap in the process, phase pugs a good idea anyway (a pile of felt for the “woofer)
Imagine a double wide Victor.

Althou with thes eyou don’t really need BSC so series wiring mre appropriate.
If you started with something like SEAS FA22 you could do it sealed.
With full BSC you’d have yo get them way out into the room.

I have maybe an extra w8-2145.
To me, the hf boosts how i like it past 4khz (near 95db).
But it needs bass boost to sound "balanced" for my prefered eq smily face.
Originally i was doing a too big sealed, 33' tall x 20" wide x 13" deep, driver center 20" from bottom. And more than last time stuffing (3lbs in 3ft3 sealed).
Basically for voice and light stuff. Can't do big rear horns.
Maybe I'll use the 3rd speaker as a center channel, ug.

scott,
eek, you are right.
6.36mH, seems about right.
Think I could use a iron core ? $8.27 and .55 ohm

Sure, although I'd try for one with a lower DCR if possible.
As noted though, in practice your step frequency may be a bit lower than the bald mathematical calculation, and a full 6dB is rarely required, so I'd be inclined to go ~6mH and be prepared to unwind some if desired to get the balance right.

Why i suggest a corner point of (0.707 to 1) times BS(-3)~4560/width (inches).
Lower in the range works best in the applications i have used it.

Right, and for floorstanders you can often repeat that for ~1 octave below the mathematical nominal. Which is where it starts getting interesting from the POV of both room-gain and potential interaction of the series inductor with the LF load impedance peak.
