Carrera vs Adelphos

Driver cost is not indicative of anything that should prejudice selection. All about implementation.

FWIW, check out a recording at least here - sounds pretty good to me.

No disrespect to the Carrera or Adelphos, but a 20lish 2-way is limited by its very nature. If you want more dynamics, clarity and bass, you need a bigger speaker; not more expensive drivers that are still small.
 
Philharmonic is $972

Adelphos is $708

Carrera is $805

Those prices are with standard crossover components. Premium parts will obviously increase the price.

And I'll have Mark build the crossovers for me rather than build them myself. So there is another cost difference of $65. ($125 for the Philharmonic vs. $60 for the Adelphos.) That brings the overall cost difference to $329.

If I decide to opt for some premium components in the crossover then the price for the Philharmonics is going to be well over $1,100, and that's pushing the budget too far. I don't think it will be worth it to me.
 
Wait, didn't you start that sh*tpost about DBT'ing boutique caps?

Cost is always a constraint but consider you're basically moving from a 10L 4.5" 2-way to a 20L 5.5" 2-way for the best part of $1,000. A 3-way that still fits your room offers more potential, from larger cabinet, larger woofer for low frequencies, dedicated midrange.

FWIW, I'd also consider Goran's larger (27L) Classic if wishing to stay in that budget range and sticking with a 2-way. www.audioexcite.com >> Classic Two – M5
Uses the 18W vs the Carrera's 15W.

The post I started about a month ago regarding the real value of premium capacitors was a great one. It went on for many pages and there were plenty of opinions on both sides of the debate. And I haven't changed my mind about it. No need for expensive capacitors once you eliminate electrolytics. But here I'm not talking about capacitor upgrades. If I elect any upgrades at all they will be with regard to the inductors where I think there might actually be a sonic difference.

Now back to the original discussion. Going from the Piccolo (7 liters) to the Adelphos (16 liters) is more than twice the volume and should be plenty for my tastes. I don't see any real benefit bumping it up further.

Low bass is not at the top of my priority list. Overall sound quality, low distortion and coherence are. And in that regard I think a 2-way will actually outperform a 3-way. If they had enough dynamic range I would probably even like a full range with a single driver.

So I'm really satisfied with my short list of the Carrera and the Adelphos. The purpose of this thread is really to find out if there is much of difference between them.
 
Classicalfan - small midwoofers can really shine in the midrange if the bass signal has been filtered out. A high pass filter at about 150 Hz will really change a small 2-way speaker.

Would you be open to the idea of a pair of L/R subs with an active crossover?

Yeah, that sounds like a very good idea. It's what I've been thinking about as well, but probably as a follow on project for Phase 2.

Hopefully I can still enjoy the 2-ways initially without implement the subs from the very beginning.
 
That's very good to hear. Can you possibly be more specific about what characteristics in particularly you like. And any that you don't.

One of things I'm also interested in is sound stage. Especially in a small room.

Any comments would be appreciated.

I can't really be specific about soundstage as it's been a while since I had the carrera's set up. I don't think they did anything wrong. The scan has a pretty warm midrange and the Hiquphon is very sweet on the top. I think I actually prefer the Satori tweeter of the Kairos as I find it very smooth and a little warmer than the Hiquphon although that might just be a little less air too.
Over all I preferred the Carrera's.
I mostly listen to small ensemble Jazz and chamber music, not a lot of orchestral music. I also always run subwoofers, but did compare the two speakers with and with out subs.
 
I don't want to be a the fun police, but can we get a reality check here? This is a 11 x 12' room. In my experience that is bedroom size. Not master bedroom, just a standard bedroom.

Unfortunately you're not going to be able to give you an illusion of a live classical performance. A wider dynamic range and large soundstage are just not going to be possible, due to the overwhelming influence of reverberant sounds instead of direct sounds from your speakers.

I'd stick with your current speakers and listen to them in the near field (<1m)
 
What's the build cost of this design?

The Reference Mini is around 850$ in the drivers alone.

But what about a MTM configuration with 2 x Vifa tc9fd18 and then 2 bass drivers like these on the side D-165 Subwoofer Chassis 175 mm (6.5 inch) All components are of high quality without compromise. | Reckhorn

in a 20 liter box?

If you look at the measurements here Peerless TC9FD18-08 | HiFiCompass and here ScanSpeak 10F/8424G00 | HiFiCompass

The vifas give the 10f/8424 a run for the money.

I'm not really clear on your analysis. Are you saying that since the room is rather small the reverberations are coming too soon to be able to create a sense of spaciousness? Or is it something else.

In any case, the current speakers are intended for use in a different room and will need to be replace. So I might as well upgrade the sound at the same time. Hence, the reason for this post.

So what did you finally settle on using? The Kairos or the Carreras?

Near field listening has no appeal to me whatsoever. I’d rather be using headphones than having speakers that close.

I’m actually getting very good imaging right now with the speakers 6 feet apart and 8 feet from me. There is lots of depth to the sound field, but the width is limited to the area between the speakers. And that’s fine for vocals and even opera. I can actually hear the singers moving from front to back in the stage.

What I’m missing is to have an orchestra appear to be wider than the speakers. Probably won’t be able to get there with box speakers and have considered open baffle as a possible solution. Might still try that to see, but will likely have to give up some sound quality in the process.
