Peerless SLS-85S25CP04-04 3-1/2" Paper Cone Woofer 4 Ohm
The SLS-85S25CP04-04 3-1/2" paper cone woofer from Peerless is an extremely impressive driver for its size. With high excursion capabilities and low resonant frequency, you can expect a considerable amount of low end from compact designs. However, beyond that this driver excels throughout the midrange frequencies thanks to an aluminum shorting ring, optimized magnet, and damped paper cone making this driver ideal for use in ultra-compact 2-way designs and portable speaker systems.

I had a speaker build I was working on but wanted it to be somewhat small. I paired two of these with 4 4” Radiators in my build and it is just amazing these are some powerful clear woofers. Probably going to get more.
