I had purchased a pair of Peerless India 5.25" Kevlar Cone woofer in 2011 and made a mass loaded TL speakers from them. As per Peerless sales person, this particular woofer was surplus stock sold to JPW for their speakers.
I still today use this particular woofer as of today in my TL box. I last week replaced the tweeter with Peerless Tymphany x25 double ring radiation tweeter. Both the Peerless Kevlar cone and the Tymphany X25 are a match made in heaven and very easy to design.
I am using a capacitorless series crossover first order. Though the bass roll-off is a bit higher, but with the gentle roll off I can still get -6dB at 70 Hz which is inadequate and will need a subwoofor the bottom end. But the overall transparency, soundstage, detailing and imaging is just super .
