Default 8" 4 ohm heavy duty woofer/midbass needed, who's Goldwood?

Hi, Im looking for a 8" driver with the following requirements. It needs to be 4 ohms, and handle 120 watts +. I'd also need it to sound good, and be able to drive alot of air.

I'm going to be using this in a car door with a 4 way (sub, midbass, midrange and tweet), with the upper limit of the 8" around 1k Hz to avoid beamyness. The lower limit will be 80-100 hz (I will experiment).

So far, I've only come across 2, the Dynaudio MW170 and the Peerless CSX 217 C (850519) drivers that meet all these. The Dyn is significantly more expensive then the Peerless.

The Vifa MG22WO09-04 looks promising but theres no specs for it yet. The PL22WR09-04 look good too, however it looks a bit on the low inefficiency side.

I also ran into http://www.partsexpress.com/pe/showd..._ID=7543&DID=7 this goldwood driver. Spec wise it looks good, but who the H is goldwood?

Are there any other drivers out there worth considering? Power handling is probably my #1 concern. Thanks.

They're a pretty cheap low end brand. Not too bad, but you wont get the SQ you're looking for...

Wow how did I guess you were gonna respond first? Hehe. Heres my thoughts though, at 100-1000 hz or so, wouldnt this be the region where the sound quality wouldnt be as important, as say the upper midrange and treble where the "detail" is?

But for $24 a driver I might just take a gamble. Parts express does have a generous return policy.

Actually, music in that range is very critical.

I thought about using PA drivers but I wasnt able to find any in 4 ohm. Perhaps Ill give eminence a call to see if anybody in the USA carries them. the alpha or beta 8s would probably do a great job, but I dunno how they sound (but I bet they can get loud!)

the 4 ohm version of jbl 2118 would be good for you. Excellent capabilites up to 1600Hz

Probably a bit on the expensive side though

Look at the Intertechnik MDS-08, that is if you can get it over there.

I've used one with very satisfying results and they are not expensive (59 euro or sometimes less)
