Peerless 830855 SDS 4" Woofer

I purchased these to build a small-ish set of desktop computer speakers, mainly for nearfield listening. I wanted something with more output and extension than the NS3's I had been using, but didn't want to step up to a 5"+ woofer and a larger enclosure. I ended up with a .15 ft^3 enclosure with a 1x4.75" port to get tuning in to the 40's.

Midbass is great; bass is fantastic, especially for a 4" driver, mids are.. Soft and mellow sounding below 2.2k but muddy above. I crossed them over to XT25 small frame tweeters around 2.5k LR2. I wouldn't recommend pushing them much higher, but keep them in their target band and the sound great! They reach and exceed linear Xmax without noise or complaint and take a fair amount of power without complaint. The port I used is too small for high power and output, but does nicely at moderately loud listening levels. I put around 5db of baffle step in to the design, so they aren't super efficient. Though, they will still fill an average size room with copious amounts of sound and bass - they won't knock things off the walls, but the sound is there. I am really impressed with them! I would characterize their overall sound as laid back and easy going. They aren't as clean and detailed as, say, the nomex cone Peerless drivers, but do very well on their own right. Definitely worth the money!

I purchased a pair of these when they were on sale out of curiosity. I put 2 of them in the same ported 14.3 liter cabinet, each playing a separate channel. I tuned the port by measuring the output of drivers and port using a variety of port lengths. I found an 8.9cm long, 4cm diameter port best, giving an impressive f3 of about 45Hz! They play loud enough for use in a small room at pretty high listening levels before bottoming. I would not recommend this as a full range, as the sound was "muddy". They could maybe be crossed over to a tweeter at a low frequency. They would make a great subwoofer added to a pair of computer speakers.
