After upgrading main speakers for clear mids and highs, contrast to the muddy bass of old active 8" Jamo210 subwoofer was too much.
The Jamo210 has well made box and working amp though, so why not a new woofer only. Weeks of browsing and studying options, i decided on this affordable Dayton 205-4.
Soundimport webshopping experience was flawless, and speaker was sent the same day.
Installation was straight forward, however a small job to chisel flange off the box mounting rim, Dayton being slightly larger than the original. Dayton is significantly heavier than predecessor and sturdier construction.
My hopes were high playing first demo song. Defined, tight bass on selected songs, yes. However i found ~50Hz way overemphasized. Some tracks playing boomy one note bass.
I realized the box tuning must be wrong. The original port tube is 115mm, and per port calculators tuned +45Hz. Way too high for the capable Dayton.
I readjusted amp. And numerous port calculations and try&error with various lengths and diameter kitchen roll cartridges stabbed onto the speaker port; there is now temporarily a 46mm dia roll in port, extruding 65mm off the box wall.
The bass is musical, punchy, detailed, linear and goes deep. Pure enjoy!
I can highly recommend this woofer as a replacement upgrade. But learn my exprience and mount an adjustable reflex port while box open. Make it so you can initially tune it from outside. And take your time tuning -- it's worth it.
Happy HiFi'ing from Finland!
