The PW1254US is avery good driver made by Eminence, the same company that makes subs for Parts Express under the Dayton logo, and Adire under the Shiva/Tempest names.
In a 6th order bandpass I can get over 100dB/W at 30hz and over 250W power hadling without 'slap'.
Most of the Pyramid poly cone drivers are not very good.
The PB128G Kevlar used to be made by the company that makes Kicker drivers and for the price was a steal.
The paper coned W10 $13.95 made in China woofer makes a great mid-bass unit and is 98.5dB/2.83V/1M (from its T/S parameters). The dust cap is bogus, but a razor blade can take care of that, and a new one fitted.
Pyramid/Pyle/Legacy/Lanzar are all the same company (Sound Around Inc), don't actually make anything, but buy many of the same items sold under names such as Jensen, Sherwood, Radio Shack, etc.
Kind of hard to draw a line when it is this vague.
