Continuum vs. Kairos vs. Adelphos vs. Solstice

[DearSX]

Hi Jeff,

I want to ask you a few questions....Jeff would the 3 way be possible with a flat-pack subwoofer enclosure like the dayton 1cuft enclosure, or perhaps a Denovo flat-pack? Would the 3-way be easier to integrate into a room then a 2-way + sub?

I just saved up enough to buy a subwoofer and amplifier (and got wife's approval) for my Kairos (still need to get the enclosure finished/braced). I am using an Emotiva Flex $200 50wx2 amp and I don't think I am doing the speakers justice. I also have the speakers on crates as stands. I have a $3000 budget, and I am not sure if it would be better to buy a $2000 JL sub and $1000 Amp or build a $600 DIY sub and get a better amp or get build the 3-way and power it all with just one 2 channel amp. My room is like 13x13 feet.

Thank you!

Re: Continuum vs. Kairos vs. Adelphos vs. Solstice

Thank you Jeff, that sounds very interesting. Would the Fusion 8's retain their sensitivity with the mag12 using the crossover you kindly shared as a 3way? If so would the three way be OK running from a 100wpc AVR? It'd be great to get the midbass punch of the mag12 without needing another amp.

Yes, and Yes. Go for it.

Re: Continuum vs. Kairos vs. Adelphos vs. Solstice

Jeff, would this work on the diysoundgroup Magnum-12 that is in your Maximus 12 speaker?

Would the crossover work? Yes. Would it work with the Continuum or Kairos. No, not in my opinion. While the Magnum-12 is an excellent woofer, it not a good choice for an application like this one where lower sensitivity and deeper extension are the trade-offs we are targeting. The Magnum is simply too efficient to work in a design like this one passively. Now, it would work with a pair of Alchemy's though.

I just did.
very interesting.

any downside to the three way version of the continuum vs the two way?

No, seems to be a very nice fullrange speaker.

Did you download the write-up? It IS passive. It is NOT a subwoofer.

:rolleyes: lol

Re: Continuum vs. Kairos vs. Adelphos vs. Solstice

will it be possible to add the module to my continuum passively or its simply a subwoofer?

Re: Continuum vs. Kairos vs. Adelphos vs. Solstice

This is an add-on for the two-way monitor. People who already possess the Kairos, Continuum, or other similar speakers only need to build the woofer modules. However, if someone wants to build the Kairos three-way from scratch then they will still need to build both the two-way Kairos and the woofer modules and combine them.

Re: Continuum vs. Kairos vs. Adelphos vs. Solstice

Should we add these Spiritwinds and Carreras to the list in the title of this thread?

I think I would wait until I got the correct box if I were you

Just an update

So are (or should I say were) those the PE curved cabs (.5cf)?
Very clever !
Are you planning any crossover tweaks due to the slightly narrower / angular baffle (how would you even calculate that?

I don't have the skills to ever fabricate something like that, but I do have a pair of 1 cuft curved cabs I could possibly commandeer until I could get a proper cab built. (It happens to be 9" wide, though 6" taller and obviously larger volume)

Re: Continuum vs. Kairos vs. Adelphos vs. Solstice

+1 on that ! I think its a great move to offer this option.

I've gone full circle on this; in the days of my youth I had my thumb firmly jammed on the Loudness button on dad's receiver. Then going through a more "mature" purist frame of mind. But after a summer full of great live shows, I'm back in the camp where the extra low end helps a lot. Most of the music I buy nowadays is from these performers I've seen. And while a studio recording is not a live event, the boost makes it seem more real and enjoyable.

I've had available 2 sets of dayton RS270's in large cabinets+ SPA500 sub amps for experimenting; not subwoofers you'd use in Home Theatre, but in this sense they are. They help even well respected 7" 2-way designs (Z-SR71). These measure well and sound fine by themsleves. But after tuning by ear and omnimic, I agree that ~+3 db is going to be a great option. without it most of my CDs can start to seem anemic in comparison. And its more than just getting another 1/2 octave of extension - there's a visceral effect in the entire bass range that just seems right (to me) .

Curious if this will be a "conversion / add-on" kit. ie for people who already have the 2-way , the sub option is available separately for the same total price as buying all at once?

A smooth slowly falling response can be very pleasing in many listening environments. About 5 dB over the top 7 octaves with a fixed shelf of +2-3 dB covering the lowest octaves usually works well. Interestingly, an Altec 19 that I measured in college had just about that exact response and sounded very good, and more recently Floyd Toole has shown that listeners tend to prefer this downward sloped response curve.
