Oooh, actually... how about the Peerless mid-woofers? Make excellent mid ranges. Something in this range:

https://www.madisoundspeakerstore.co...y-cone-woofer/

The motors are really exceptional bargains, any version of this would do really well as a mid that could keep up with a 10-12" woofer.

They used to make a woven fiberglass line, same motor.

I think this mid/woofer + XT25 + good woofer will easily exceed the original NS1000. Maybe a little tight in dispersion though.

The Dayton RS-52 is a very nice dome midrange, but you have to protect it: it sounds clean within its limits, but terrible when those limits are exceeded. IMO, the Yamaha midrange is what makes the NS1000 sing. I don't believe that the Dayton can compete, especially when it comes to dynamics. Many have suggested that the woofer is nothing special. I'm not sure if that is true, though. In the NS1000 implementation it is also curtailed, and it does not do enough to draw attention to itself. Its Thiele/Small parameters suggest that it is suited to bass reflex loading (there is an aftermarket modification that uses the hole for the binding post cup as part of the port to convert it to BR).

As for the tweeter: surprisingly, I found it to be ordinary in performance. Most budget tweeters will actually work in its place, due to the high crossover frequency. And they would give you that extra high frequency extension. Strangely, though, I had no clue that it has an early roll-off until I measured it.

If I were to describe the NS1000s, the first words that would come to mind would be detail/resolution and dynamics. Today, if I wanted to achieve those characteristics, I'd look to pro style drivers.

I have not heard the Yamahas, but listens dayli to a pair of JBL XPL200 and are very impressed With the 3" titanium dome they have. I even use 3 XPL 140 as center and rear channels when i watches Movies. they have also the JBL 095Ti dome.

From personal experience, I can testify that driver is not very good, with poor definition of midrange and "submerged" vocals. I tried many different enclosure and crossover configurations over a period of YEARS and could never get the vocals to come out of the enclosure. It's just a bad driver, and not a good substitute for the NS1000M.

The Peerless NE123W-08, on the other hand, is an excellent driver, with amazing detail retrieval and beautiful vocal projection. I think it might be one of the best midranges available. I bet it would fill the midrange gap very nicely in NS1000M's, which I owned just after they were introduced in mid-70's.

Peace,
Tom E

I've not tried the 4". The 5-ish is very good. But I am listening to the woven fiberglass version.

hbc, help me to understand why the original units, which are perfectly good and in working condition, need to be substituted.

The driver I recommended is a better design in every respect. Among equivalent designs, cone material is a crucial factor. I would never consider using another poly cone mid. Fiberglass or kevlar might be okay, paper/wood probably the best. Metal would require complex crossover to trap ringing, but otherwise could be good.

Midrange is the most important driver, and it is the one that can least be judged by freq response curves. It just doesn't provide enough information about the actual sound of the driver. Smooth curve does not always equal beautiful sound.

Peace,
Tom E
