And Now For Something REALLY BIG - Page 30

Thanks Line. Not only is my box size fixed, the placement in the room is faily locked in as well. So that leave an adjustable port tube to vary the turning frequency.

I'll download the D & B simulator and play with that this weekend.

I'm not sure why you'd be searching for an appropriate driver for the onken, when you can regularly get a pair of Altec 414 for $300 + shipping. That leaves quite a bit left in your budget.

Finding a pair of 414 in the UK or Europe might be best for the budget. With those can can build the "Petit Onken"

At around 22lb a pop its way too expensive to ship them over and tbh I'd want any 'vintage' drivers I get re-coned anyway. That puts the purchase + shipping + shipping to be re-coned + re coning + shipping back to me price way up there again

I wonder if my friends from Arizona are going to visit any time soon

I love the fact the petite onken is still a huffing great cavern of a box!!! I didn't realise it was soo BIG

Ship them where? If you find them on that side of the pond, it should not be too bad. I'm sure you can get recones done in the UK. Westrex made a whole line of Altec drivers there in UK. They are often a bit better built than the USA versions.

How risk yis buying old altec drivers an dshould the GPA versions perorm better for any reason? Also, how risky is demagnetization in old Alnicos?

Pano · 4th October 2012, 05:20 PM

You never know what you'll get, unless you can measure them first. Even recones don't always go as planned.

As much as I love them, buying used Altec drivers is always a gamble. Lady Luck may smile on you, or she may not. For this project, new European drivers is probably the way to go. We've looked at a few good candidates.

The GPA versions are less than $300/pc.

Pano · 4th October 2012, 07:34 PM

Sure, but shipping and import/VAT UK style would raise that amount a lot.
