Volt Woofer + Accuton Midrange + Ribbon or Beryllium

[realhifi]

I am very new for DIY, and I want to have a good floorstanding loudspeaker for classic music (Piano, Violin, Cello Solo, and want to have a new speaker to listen great Symphonies)!!

Woofer (for <250Hz):
It sounds Volt B2500 (10") is better for my needs, but, I have had a pair of big RV3143 (12"), they need too big space (80L), is it possible to save space? Add more magnets? Are RV3143 good for classic music?
91dB, 8ohm

Midrange (for 250Hz - 2200Hz):
I am thinking about Accuton C173-6-090.
93dB, 6ohm

Tweeter:
Chinese Aurum Cantus/Fountek Ribbon (100dB, 7ohm) or Scanspeaker R3004/66400 (91dB, 4ohm)

I am not sure if those drivers are fit. The ohms are all different, is this a problem, and how to solve it?

Thank you!!

Better for you to try this http://www.troelsgravesen.dk/SP44.htm if any other ideas.

Hope this helps.
The Accuton C173N-T6-90 is also a nice ($600) driver.

Price per pair: €34,000 ($45,200)

I have been using the 3143 for a while now and it does require some volume but it will give the same in return...VOLUME(LOL)

I too have been using 3143 for a while now but in a t/l which is even bigger (140L) and I cannot fault them at all.
PMC and Quested Audio use them in their bigger, pricier monitors (Quested HM412 uses four of them per side for $66 000 but they do come with a number of amps etc for rooms of up to 35 square meters or 375 sqft!) and they are quite popular for classical rec studios.


Is it just me and I missed something or does the waterfall plot for the Accuton Inductor linked to look somewhat less than ideal?

Do not waste your money on any Accuton driver - way over priced and outperformed by other, much less costly drivers.

I recommend the ScanSpeak tweeter, and while you're at it go for ScanSpeak on the midrange too - if you can afford Accutons get these, for the reasons mentioned above.

Thank you!

It sounds the Accuton is too expensive. Actually I didn't have a chance to hear them.

Days ago, I saw a pair of Scanspeaker, sounds great. OK, I will have a further look on Scanspeaker.

I will have lots of questions.

Sounds Volt RV3143 are good. Good to hear. I will learn and start to design enclosure and xover.

Woofer: Volt RV3143, 91dB/W/m, 8ohm (have bought)
Midrange: Two Scanspeaker 18W/8545, 88dB/2.83v/m, 8ohm
Tweeter: Scanspeaker R2904/7000, 94.5dB/2.83v/m, 4ohm

Is it OK?

How to convert 94.5dB/2.83v/m to dB/W/m??

2.83V is 1W across an 8 ohm resistor Brett

What is not the same with a different impedance. Read here explanation.

94.5dB/2.83V/m for a 4Ohm tweeter should translate to 91.5dB/1w/m if I'm not mistaken.

For easy of work go to ScanSpeak Projects
If not, you will need a new xover.
I like the Scanspeaker 18W/8545 idea/implementation for your new speaker.
