Sub from 28 HZ over 100dB

Hello,

I research this forum, and I looked for sub , whoch play from 28 Hz over 100 dB.. I need it to use with digital pipe organ. So If you can help I will be very happy.

I know that is not so many i deatils, but frequency is the first what is most important.

100 dB,s at what distance ? The first thing that comes to mind is a ported box

I assume you mean 100 dB/W/m? In that case 2 x 18" in a reflex would do. If 30 Hz is sufficient you could build a single Cubo Sub , if 28 Hz is mandatory you could also look for the Othorn (found at diyaudio.com).

Best regards

Cubo

Most important is play from 31 HZ 98 dB. I check it and...

I bought sub X1: speakerplans.com/index.php?id=x1

I used RCF LF18G401. Its working good, but from 34Hz.

Could I put in this box (X1) other speaker, which is playing lower , for example RCF LFG400 , RCF L18P200N , or something from this website:

defo second a reflex tuned to 25hz, it will be a big box....

Reflex box tuned to 25Hz will never get to 100db 1w/1m. He needs a bandpass box. A big one that is.

So, could help me to find any Bandpass project ??
