Attachment 11030On a side note I purchased this recently for under dash ,not a bad sound quality.

Cool! I'm interested in these, seen em before on ebay (US) and they have come up before about half a year back.

I'm interested to know what they can sound like. Bearing they are replacing an old Rola-Plessy, and that mostly people would just connect the old radio up, is not a test, but that baffle looks good to me, I wonder has anyone got one of these running with decent headset?

How are you hooking yours up Indy?

Looking at the design of these, I think there is a chance they might sound Ok, I'm curious bout these. In a previous thread, the last comment said something like 'no speaker can sound good without a decent sound box'... well actually thats both true and untrue.

All loudspeakers of course used to need a decent baffle, in the 80's and 90's this was usually handled by the enclosure (or sound box) but modern tech on loudspeaker design has produced some pretty awesome sounding devices without this. (Not Hi Fi, but closer than one would have imagined) I have wondered, if the idea with these is that the mount to the metal behind the dashboard could create a soundboard.

Anyways, great choice, how does it sound?

Dave I have a basic Alpine stereo system and I just mounted them straight up to the dash, no soundbox,i have a GTS so the rears are mounted on the rear shelf.It provided me with a bit of front sound ,they obviously don't have the basey sound like the rears ,just adjusted the fader to equalise the front and back . sounds not to bad and I didn't really want to cut holes in the kick panel ,worth the money in my opinion.

Yeah, I thought they might sound Ok done like that, good to know! I'm considering doing mine (vans) with one of those and the original radio, and then a totally separate sound system installed in the back, front drivers behind the seats, and rears and sub in the van section, dunno where I'll put the head unit for the second system yet though. It's gotta be easily accessible by the driver of course.

btw I have a number of big subs and amps all new (Chinese made of course, but it's the best from China) left over from an internet business I attempted to start a few years back. I am gonna list em for sale at some point when I get around to it, In the meantime, if anybody reading this is looking at doing up their stereo with a big amp, and sub, feel free to message me, its all high quality mosfet electronics, just no flash brand name and without ridiculous labels like "3000 Watts" written on em. Most are about 120 - 140 W RMS and frequency response close on 20 - 20,000 hz. (Hi Fi). Hi/lo pass filters, daisy chain option, remote start etc.

120 W RMS is bigger than most of the stuff the big brand names etc make even when they call it 1500W (plus) PMPO, but most buyers don't understand the RMS rating..... or frequency response, so I gave up on selling it for a while, but I'll list it eventually.

Anyways, Its good to know about that in dash driver, great for replacing the original, I might have to get one of those too!

Just a follow up on the speaker fitment,could be worth thinking about applying some one sided foam tape or something around the edge of the speaker mounting plate as I found out it does tend to vibrate while driving,being metal on metal with the two wing nuts.
