[Fi Audio]

We will be going into production on the smaller 15" IB subs late next week. I will be posting more info after I get caught up from the last two week long shows I have been attending.

Single 2 Ohm coils and $129 each or $119 for 4+ for HTS members

Specs for the smaller 15" IB sub are:
Re 1.6 Ohms
Fs 24.4 Hz
Le .72 mH
Qms 4.00
Qts .77
Qes .64
Vas 269.5 l
Mms 145.4 g

Solid little IB sub with great sensitivity.
We have limited stock right now, but will get a solid production run going after Thanksgiving.

That should read Qms 4.00, right?

[Fi Audio]

Yes, it should. Corrected... thanks

Without going for extreme SPL, how does the SQ of this 15" IB driver compare to IB-modified Q15?

Thanks,
