HeHe,
Look what came with the post yesterday. :Pumpkin:

I'am very exited to share Igors thrilling experience.
Will be as soon as I reach my summer residence in France.:cool:

Yes indeed. They seems to be very well made.
Thx for the recommendation.
Actually they look better than on the picture (delightfully transexual).
I plan this combo : Pumpkin-F4-sonido.

Mpmarino : would the pumpkin be able to drive an F4, thats the question?:devilr:

Nice looking speaker Manu! I hope her tone is as nice as her looks.:)


Hey, I'm in pretty good company here. Would you guys mind an off topic question?


he he, I didn't think so. I need a set of 15" drivers to accompany my altec 511/902 "drek" "squeekers". Aside from the altec 416/515, the JBL stuff, and the RCAs choky won't give me - any other options you may suggest? I feel like the JBL and Altec stuff has been priced out of it's value and I have a feeling I'm not going to see a 50lb package from Serbia.

so far a couple I have found:

1) an eminence built cast 15 that has been modeled to replace the Klipsch Cornwall woofer. Nice parameters, nice quality, good value and a great reputation with Klipschites.

2) this looks interesting - nice price too...

sorry for OT

:rolleyes:

If you aren't sure that you need or like or can afford place for big horns for them (and that is without doubts best solution) , you can always pair them with Eminence Beta 15 ( dirt cheap in Serbia,at least) on OB ........ JamesD is man responsible for Quasar variant , so attractive for me ;

somehow I have doubts that :Pumpkin: can drive F4 ...........:hot: :devilr:

where is that residence exactly?

somehow I missed Tour this yr........ at least what I do on reg. basis - watchin' it on Eurosport.....

edit:

did I told ya already (?!?) - Mau 12 is also very good candidate for that dreky driver
