ciao non riesco a trovare la tromba h290 / h290c dove posso trovare le misure interne esatte per costruirla in legno oppure ci sono alternative Hello I can not find the trumpet H290 / h290c where can I find the exact internal measures to build in wood or there are alternatives
The shape is proprietary. I can tell you this though - It is oblate spheroidal at the throat and transitions to elliptic cylindrical at the mouth.
ciao per il driver b&c de 250 va bene la tromba h 290 oppure va bene la b&c me45 Hello for drivers b & c de 250 fine trumpet h 290 or fine the b & c ME45
Most compression drivers work well with the H290C waveguide. That said, the B&C DE250 has been specifically tested and approved. The H290C waveguide and DE250 driver are ideal for one another.

quanto e il prezzo di spedizione e importazione per italia and as the price of shipping and import to Italy
The best way to get shipping quotes is to put an item in the shopping cart and begin the checkout process. It will ask you for your address and use that to calculate shipping by several methods and shippers. It doesn't ask for payment information until after it has calculated shipping costs, so this is a good way to check prices. We also have a freight forwarder available. When you enter a non-USA address, the Bongo freight forwarder banner appears, allowing you to create an account. When you get to the checkout phase, click the Bongo banner, and create an account. They will provide a USA address, which you will then use in the Pi Speakers cart, by clicking "change address" and entering the Bongo-supplied address. This will then start a freight price recalculation in the shipping cart, and your prices will be much lower.
