I understand the B139 is good for a 100L ported cabinet, so an isobaric design with two clamshell woofers would only need about 50L. Downside is that a single B139 has about 83dB efficiency so isobaric would be 80dB so quite low. -
Irrelevant. I had a vintage Rotel RX150A SS reciever which created a grand total of 8W which with some efficient older Toshiba speakers sounded fantastic and had plenty of volume. I've now a a few different amps including a 10W SE tube amp, a 45W Push-Pull Tube amp, a 25W class D tube hybrid amp and a 50W T amp. All three have more apparent volume than I need and sound fantastic doing it..... I think this has more to do with matching the right amp with the right speakers than anything else. 10WPC Oldchen SEP amp - 96.5db Dayton USA PS220-8 speakers 45WPC Oldchen Push-Pull - 89db Aurum Cantus F620 speakers 25WPC Nobsound MS10D Mk2 hybrid - 97db? Pioneer CS-88A speakers 50WPC S.M.S.L. SA50 T amp - 89db Poll TSi100 bookshelves + Wharfedale SW150 sub (my gaming computer system) I've actually listed the systems in the order in which I rank them in terms of sound quality.... I think the lowest wattage system has the most useable volume also. Go figure right? -
I would pick the ProAc, no contest. But then I do like the ProAc sound. -
strangely enough Dave, I have the same dream about you buying something. -
Two completely different sounding speakers. Both are very good. The NS1000 has all the midrange and treble detail while the other is a very good warm sounding but detailed standmount. Refer to the many threads on the NS1000 as it will depend on your ability to set them up properly, your matching amps and music match. The NS1000 don’t do great bass also. The Proac is easier to setup and more forgiving but extremely gutsy standmount. There are many other Proac alternatives like the Studio 200, 250, Response 2, 2.5, 3, 3.5 and 3.8 of the late 90s and late 2000 period.
