Thanks Pano. Is that the thread by weltersys you are noting above? if not please can I have a linky?

does the resonance peak occur with the impedance peak in CD drivers? I can easily get away with low power listening at home and then change the crossover for out and about use at higher volumes. The joys of the minidsp await!! (not sure about feeding it my vinyl collection thou - any thoughts anyone?)


I'll use this while I get used to the sound & save up for something more.....um......horny

Yes, the driver test thread by Weltersys.

Interested to know how the little Faital horn works out. I can't see a 14" horn being able to cross cleanly at 800Hz, but you never know! Hopefully, you'll be able to tell us.

JRKO,
FYI, i have been reading about the minidsp while waiting, and it has some noise issues with high efficiency systems. Gain structure becomes very important or noise is an issue. I wasnt sure if you were considering it as XO unit, having mentioned it to me. I have not heard these issues with Behringer.

Do you mean 14" as in 13.8" mouth width or was it a 1.4" without the decimal?

I'll have to look into the minidsp hi eff noise issue (any threads welcome). As I understand it the Behringer units can cause issue because they run at 7v or so because they are pro balanced units.

I'm still not sure about shoving a perfectly good analogue signal thru the ADC-DAC system but thats another storey & more reading........

I agree, just a "in the meantime" option.

I meant the mouth width. I was being kind rounding up to 14". FWIW, the Altec 811 has a mouth width of 18" and it's called an 800 Hz horn. Cut-off is about 500 Hz. As much as the modern marketing departments try, the laws of physics are hard to bend.

Settlement cheque arrived in the mail!! Breakers yard had 2 of my model in unknown colours. Drove up with a friend and searched among 2000 odd cars. The first one we found was green. A little more searching and we found the second one - an exact match in colour and trim !!!BONUS!!! Also picked up a bumper as mine had a bad respray that is peeling. Not bad for 100 all in.

Parts are stored in a mates big garage awaiting a rainy day (awaiting??) when he's free to help fit them

Now I have a few pennies to spend on drivers and taking the very supportive & patient Mrs JRKO out for a meal.

and now for drivers

Faital Pro HF144 looks good to me. It will give me some latitude in crossover freq., has the recommended Ketone Polymer diaphragm, is a 1.4" driver with slightly higher power rating, lower crossover point, and maybe a few more horns are available for 1.4"(?).

Before I press the button at the end of the week are there any other suggestions for around 150 a pop?
