Well most of you know that PE had a sale over the weekend on the RS225-8ohm, so i decided to pick up a pair, total was $70 ~ $83 shipped to me.
First impressions:
DAG, these things are beefy as hell, and damn pretty, the metal cone and phase plug are sexy as hell. Straight up boner driver here people :D Just rudementary playing with the driver, and equal pressure on the cone to see the available excursion, these things have got some mad excursion potential.
I plan on mating them with an already ordered pair of WR125S's and my HT LPG 26nafm's that i already own (FM for flush mount flange, around 1" wider than car version). Still waiting an email from Dan at Adire for quote on having xovers built, or i may build my own if time allows, and i learn how :D
Power/Box/Xover:
I know it sounds really ghetto, but i broke out a rather sturdy cardboard box, and ghetto rigged a little listening test, hooked up to my home reciever. The cardboard box measures in at .58cf, a bit on the small side, but my only other box was the PE cardboard box they came in, it was exactly 1cf, but i didn't want to butcher it if i needed to send them back for some reason or another. So into the .58cf box 1 went. PE recommends .8 sealed for an f3 of 58hz, and 1.5cf ported for an f3 of 35hz. Power off of my Reciever is around IIRC ~100x2@4ohms in stereo mode ( only L & R, in surround mode its 75x5@4ohms). No xover was used in this test, it was played just as it came out of the box, just for shits and giggles :D
Results:
As far as i can tell these drivers are really detailed, and the response is very nice and extended for an 8" driver. Recommended playing range was up to about 2k, and this seems pretty right on. I just listened to a bit of radio, flipping through different stations to see how it handled differnt types of music and all, and i was very pleased. The actual FR shows a lack of any info b/w 2-4k, and some cone breakup issues from 5k up. and from listening briefly in the too too small ghetto box, in some ways this is right, but i've never really heard cone breakup, so it may have been my inexperience in picking it out. The vocals coming out of this 8" are a beauty, upper female vocals seemed to lack though because of the 8-10db drop from 2-4k, and it seemed rather right on, which is why the upper female vocals seemed to lack. Off axis response seems amazing for this size driver, dosent seem like it starts to lack till up around 2k where the response starts to suffer.
As far as midbass goes, it seems like it has the potential to have a nice bit of output, which was limited at the time from a sealed enclosure too too small, PE recommends a .8 for a f3 of 58, and even a 1.5cf for an f3 of 35 hz, and i can beleive it. As far as cone movement in this .58cf enclosure, nearly non-existant, but it was still very nice and firm in the range it played. I definently think if i could get it in a larger sealed or ported enclsosure this thing would shine in the midbass region, I couldn't even see the cone moving at all, and it still did really well with some output levels, granted it couldn't drop as low as needed because of the small box.
All i can really say is i can't wait to get it in an appropriately dampened ported enclosure and let it wang bigtime.
These drivers are awesome. I should have more uneducated reviews in a few days or a week on the WR125S's that belong with them, i'll give a little review like this one as soon as i get them in the mail.
Dang i know you've wanted more people to review things so i decided i'd throw some out for ya :D
Hope this is appropriate and shows my lack of knowledge :D
Stay tuned for the WR125's later this week or early next week.
