Postcript to my previous review

By: on 17 December 2014
I purchased a DATS measuring system the other day and I measured a number of run-in Dayton RS255-8 drivers. I have to say the proximity of the measured spec's to the manufacturer spec's is quite a revelation. It leaves me with a lot of confidence to look at other Dayton drivers for future products.

Bang for buck!

These drivers are a low distortion unit. Their specifications are excellent and they sound great in a range of different enclosures. If you need more sensitivity then the 4ohm version is worth a look. Low inductance, reasonably smooth response - considering the stiff cone material. The large cone area and long throw mean that the driver can keep up with some heavyweight (expensive!) drivers. Try to find another driver that offers all these features at even twice the price! Check of Zaph's tests on his blog.
