Hi Soundhead,

Why do you want to morph a mid bass shoe dryer into a sub?

bjorno this the design I want to put the speaker

It's a 3 meter long horn ...

112 dB 1/w/m 3ohz à 125 Hz à -6 dB

bjorno · 1st April 2010, 07:05 PM

So your HR 'con' numbers should be in inch and not in cm?

Hi soundhead,

First, I think you have to relax your peaked requirements concerning using the proposed driver.

The consequences when stating: ‘25hz to 90 hz at 130 db’ and then the proposed cabinet type here above resulted in: See the 11 m^3 horn shown in the submitted picture.

A more sensible design is simulated too, the TH, that due to the low expansion rate and throat compression = (1:1) should be stuffed like a T-TQWT in order to gain SQ.

Conclusion: Would the proposed driver be good substitute to the RCF-18N401 in posting #3? See the second picture here below.
