Speakers w/Full-range Drivers

[Chrispy]

I have never been clear if transmission line designs are more gimmick vs reality. What's the ASR finding on that?

They seem a very good way to go but mostly in the DIY realm since few offer it otherwise. The extra cabinet construction costs are probably a reason you don't see a lot of options in this regard.

In a case of synchronicity, I have recently re-activated a much-beloved pair of mass loaded folded, tapered quarter-wave tubes (ML TQWT) enclosures using slightly tweaked Radio Shack 50-1354 EDIT 40-1354 (sorry about that!) twincone drivers. They are quite nice.

The notion of "undersized to purpose" drives is an amusing one -- look at the loudspeakers @amirm has tested over the past few years.

Are those the same drivers they used to call holey basket corals.? I used to by tube driven sony RTR's to harvest those & all the mullards, BB's, etc..

No they're decidedly low(er) rent drivers than the holey basket corals. The R/S drivers' provenance isn't known (at least by me), but they're good sounding little drivers.

The Corals are quite different and, indeed, held in considerable regard in some circles. I don't have much experience with them myself, though.

Would be interesting to compare that old driver to a modern similar equivalent, like Mark Audio p mica full ranges

Or even a cheaper alternative of Bose driver

The Coral Holey Baskets with alnico motors are ideal in these back loaded horn enclosures ( Frugal Horns ). The B&G planar tweeters add just a bit of sparkle on top. I don't listen to them in this room but we were working on the floors so I moved one there for this picture.

I had private audition of Etheraudio Normal 28 Full Range Loudspeaker 10yrs ago.
Played house, techno and disco on them 2+ hours . The sound was excellent to my untrained ears, but the very narrow sweet spot , wardrobe's size and look and of course the price was no-no for me.

If I had the space I would have kept the Holey Baskets in these open baffles.

The are a reality and well designed ones have some of the best low end responses I've heard., the science backs this up their principals. There are advantages that a bass reflex can't accomplish but by no means does that make them bad.

In the modern sphere, PMC is the brand I associate with transmission line designs, but have no experience with them. They don't measure well as i recall, but that's just one brand and tells us nothing. Subjectively, some of their recent home and $ friendlier stuff seems well liked.

I always thought the Serene Audio Talisman was an interesting design although $500 for a little pair of one-way desktop speakers is way too rich for my blood as cool looking as they are, I've read good reviews about the sound too

One way is a poor term, full range driver is better.

There are not fullranges that realy achieve full range

 

[Salt]

What's the definition of full range transcribed into FR, Distortion, and so on ...?

 

[Penelinfi]

Maybe it's just driver designed to play without a filter.
Of course there are some woofers designed like this too.
Maybe 100Hz to 10kHz . Even then, there are 1 inch "full range" drivers.

I get acceptable bass from a 15" Audio Nirvana Classic Alnico driver in a ported cabinet.

 

[Chrispy]

Just the way the term is used, it only uses a single driver to attempt the full range is one way to think about it I suppose....like thinking all floor standers are full range even with multiple drivers

Vertical range (SPL) in dB is missing, so no way to conclude.
50 dB is the norm.

 

[Poultrygeist]

Wide band is more descriptive than full range.

 

[Poultrygeist]

I use all wide band speakers in this 5.1 system. The mains are MLTL Lowther's which make so much bass I rarely use the sub.

Thus do I try to use the term extended-range driver for a single-driver "solution" -- and/or I will usually put "full-range" in quotation marks.
