Best midrange ever? Worst?!

The best driver I've ever used from 100 - 1000hz is the Seas W22EX. You just can't use it over 1200hz max or it falls apart quickly. Basically if you can use it in a way that doesn't require notch filters, it's incredibly detailed and transparent but still has enough meat to it (unlike an Accuton) to keep the listening experience emotional.
 
My Allison CD7's are unstinking believable in the mids. Unfortunately at times more mids than anything else. Voices are clear and present, as are any instruments in the same frequency range. Placement with these though are very finicky, for my taste anyway. Kind of a love/hate relationship. When they're good they are stunning. Just not consistent enough.

Sadly some speakers, like HPM's really accentuate some recordings more so than other speakers. My Haydn's are probably the most "behaved" and consistent speakers, I guess that would be the definition of neutral. They don't over accentuate, though with some stuff they fall short, mostly in the bottom end, but for the most part musically that's not much of an issue since most of what I listen to doesn't go beyond the range of the Haydn's.
 
:drool:To me, my KLH6's and 17's have some of the sweetest mids I have heard in a "common" speaker. I do have some Grundig "FR" ovals. and one large Isophon FR driver that have almost "spooky-good" midrange.
 
Altec 515Bs, and 802-8G compression drivers bolted to 511B horns. Very nice mids

++++1

I agree whole-heartedly about the 802-8g drivers/511 horn combo. I damn near gave up on horns. I have Quad ESL-57s, Acoustat Model 2/MH and Dahlquist DQ-10s. All very nice and well behaved in the mids but there is just something about the detail and dispersion of the above said combo. Especially when set atop a pair of Cornwall bass bins. It is unlike anything else I have heard. It just creates such a huge and dynamic midrange soundstage. The JBL 2440/ 1200Hz wood Smith horns is also great! That being said, my fave is still the Acoustats or the Quads- too close to call. The Acoustats sound better overall being a hybrid. Once I get the Levinson HQD (4 Quad ESL-57s) fully put together with the Decca ribbons, I'm sure it will be my favorite hands down. I would like to hear beryllium diaphragms in the 2440s- that would be to die for!

I couldn't agree more, the cornwall cabinet works exceptionally well, when loaded with Altec 515Bs, and afore mentioned horn combo. :thmbsp:

This one not too bad

One of Pioneer's more exotic mids. Boron cone. Large magnet structure and cast frame. Guess what it came out of? I have it in two speaker systems at the moment, one you can see in the pic. Very detailed sound, although I am sure I could improve the blending with a better Xover.

Gibbs a little OT, but what part of IA are you in?
 
"Midrange is where the Music is". True or false?

Favorite midrange? DIY?

Worst midrange in a system-- non-tower AMTs?

I've kinda given up on 2-ways.

Integration problems in the critical listening band-- midrange -- where the ear is most sensitive -- seems best handled by a driver specifically for this. (unless you go planar...Maggies)

What I've got with incredible dedicated midrage: DQ-10, 12, 20, DQM-9, 9c, Bozak Symphonies.

Will be testing another 4-way tonight for midrange worthyness: HPM-series.

After some experimenting I'm convinced that a truly great midrange must have as a foundation a smooth, lifelike, well-integrated midbass.

For DQ-10s, his means close conformity to the original T-S parameters of the original (Advent-based woofer with improved VC).

However, I have not seen these specs. If I had the equipment I'd calculate them.

The tension between trying to achieve IT ALL:

full-range-ness,
best-integration-between-drivers,
and dynamics

...theoretically should be easier today than the vintage era. Better materials, tests, and QC?

If someone made a better midrange cone speaker than the 6" Bozak metal cone jobs, I haven't heard it.:dunno:
 
Perception of music is a biological/neurological process. Our ears and cochleas are not ideal flatline freq analizers. Test yours.

Speech has vowels - often 400-1000Hz, plus consonants, often 2000-5000.

The Fletcher-Munson curves appear to mirror this speech/highest hearing range theory; two peaks. Most critical xover point? In between those.

But how about the other animals in your house?
Infrasonic sub for Pidgeons, plasma tweeter for bats?

----

Goldfish (Carassius auratus)
30-8000 Hz

Greater horseshoe bat
(Rhinolophus ferrumequinum)
2000-110 000 Hz

Asian elephant (Elephas maximus)
16-1000 Hz

Domestic dog (Canis familiaris)
40-40 000 Hz[/SIZE]

The Bozak Symphonies probably have even-better mids (Haven't heard a pair in years), but the 5" mid-woofers in my W60E's are without a doubt the best-sounding I've heard since I got these things. It's a warm, smooth, full-sounding mid that's completely-free of fatigue. Extremely-lifelike (Voices sound like they're in the room) and yet very-vibey. They're just perfect. I've listened to new B&W's in a listening room, and they just don't do it for me the way these do.
 
Mids in the Symphonies are to die for. May have to do with proper integration with the woofers, which are special and unique. Also had better luck with Warfedales than B & W, based on SQ...B & W are great looking though!

dnewma04 I hope there's a pic of your setup around.

Haven't heard Quads yet, but SoundLabs are the current e-stat midrange champions here. But they skitter way off the primary path of AK's vintage/DIY/scroungeAsaurus focus... :dunno:

Thought Pioneer's later 70s efforts crossed the woofers very high, way into mids so that Pioneer is probably a mid-high, not a true mid driver.

According to this I'm now a goldfish.
:yes::D

Wow, I am surprised that ADS hasn't gotten more attention in this thread. I have found all the ADS speakers I've heard to have beautiful mid-range response - the L400 (both versions), L-710, L500. I honestly don't think it can be beat at the price point.

I also give a vote to my AV123 LS6 line source speakers that each have eight 6.5" cone woofers and six modified Graebner Neo-8 mid/tweeters. These sound fantastic to me, at all ranges.

Great info on this thread BTW. I appreciate the technical discussions, even if I can't always follow them. I'm working my way through the Master Handbook of Acoustics, so eventually I'll understand it all! muahahaha
 
Best midrange powered by an arc welder:

Dahlquist DQ-10
Koss 1A

Best midrange powered by by a 36/wpc tube amp:

Magnepan SMG
DCM TF-350

This is with extensive hours on all the above.

Maggies? Really? Wow, I wouldn't have thought (although it doesn't sound like these are your typical Magnepans - Never seen the SMG's before). I'll have to check out a picture online.

I would love to score a nice pair of DQ-10's. That's my kind of midrange.
