What's your pick for drivers in an ultimate 3-way (for music)?

[SunRa]

This I find to be a great sistem, with room to improve maybe. I'd go with open bafle LF units too..

Tweeter: RAAL 70-10
Mid: Jordan JXR6HD
Woofer: 2 x ScanSpeak 21W/8555-01 sealed
Crossover: 300 Hz & 6-7 kHz

So, would you run both 21W/8555 crossed at 300Hz? or one at 300Hz and then one lower? Does comb filtering occur at these frequencies?

Hi motion,

I think your choice is right. The C44-8 is very well regarded in the (quality) diy field and surely can handle 800hz 24db slope even with high power. IMHO you could retain a quality 8" in the lower frequencies, 800Hz generally is not a problem (about of-axis energy and distortions). I project to use the C220N-T6 with this small upper-mid driver (I have a sub to handle the lowest fr)

The setup would be active. Yes, I'd run both 21W up to 300 Hz; they would be connected separately to two pairs of terminals and use with them a stereo amplifier with two pairs of outputs per channel or a regular one with a bi-wiring cable or a modular 4 channel amp with an amplification module for each driver.

I'd say an ultimate 3way needs a lot more cone area for the bass. One 6.5" just doesn't do it.

I'd go for something like:
AudioTechnology 15 E xxx (15")
AudioTechnology 4 H xxx (4")
LCY or Raven ribbon

XO-points as high as possible.

Audax, HD3P on the top, HM100Z0 doing midrange duty, and PR240Z0 on the bottom. Oh hang on, that's what I already have.

I don't know about those 15'' Audio Technology drivers... That poly cone might be to soft to offer a fast, tight bass, the bass might be too fat and woolly for my taste. And I don't know if it's good to pass directly from a 15'' woofer to a 4'' midrange. Thats why I selected 8'' woofers; the bass from them might not go very deep, but the one they will make it will be a quality one and if I need to go deeper there are subwoofers.

Maybe the title of the thread should have been about the ultimate 4way because a 3way may not be something that could be called ultimate .

What I know will work, and very well.
JBL 2226H, ported 75L / 40Hz
JBL 2123H 300 -1K
BMS 4552 or Beyma CP380M on a great flare like a DDS ENG1-90 Pro.
95dB sensitivity and less distortion than smaller drivers working hard. Excellent motor and diaphram designs.

I'm researching newer options of similar drivers. Audiophile stuff are like toys compared to these.
