But go for it! It really is not difficult if you don't need it to be absolutely perfect
we'll only be having one amp6 and two 7,2 Ah batteries so I don't think the weight will be a problem, now I'm just looking forward to start building

Hi!

I'm finaly almost finished the boomer,
And testing the Lepai 2 x 20 W 4 ohm

How much increases the volym in db
With amp 9?

What is the max power in this construction?

Max power on the magnet says 200 Watt
On the HP-10, ??

With a amp9 on 24V it would be twice as loud (+6dB) but use 4 times the power.

I estimate about 50W RMS per HP10W as maximum.

There should be no problem in using this instead, right? It's still the same tuning 69,8 hz. I'll just have to cut the port exactly 5,63 cm

I'm building half a boominator for another camp and they are on a tight budget, so this port is appealing.
Rubenn, did you end up cutting your 75mm port of at 5,63cm? And if so, was it satisfying? - I've got the exact same port, and would like to know if 5,63cm is the works :-) Thanks.

I think I actually chose the tuning as 82 hz with a port length of 2.53 cm. So I sawed a part of the tube off. It was actually pretty satisfying. Good tight bass. But I reckon it will be better if one would "perfect" it.

Remember that I also chose the IMG Stageline SPA-10PA as the HP-10W wasn't available at the time

Question for Saturnus actually regarding this function in WinISD: How does one find the optimal tuning frequency for the specific driver? Because there is clearly a difference when choosing another driver
