SB Acoustics 12” SB34NRXL75-8

Hello,

I have bought pair of 12” SB34NRXL75-8 1 year ago, I made a custom cabinet for them and crossover. However, I have tried the best result was not very satisfying. I wonder, if anyone can give me any advice for cabinet (material-dimension), and also what kind of crossover should I have to use on it if you have any scheme I will be appreciated. I will use them in HiFi system, in range of lowest Hz to 120 Hz.


Thank You,
Nihat

You don't mention anything about a midrange or tweeter, without which, there's no need of a crossover and an unsatisfying result would be a given .   Any advise, regarding cabinet sizes,  compatible components and crossovers, can be gotten from the guys at Madisound(they stock that 12").   It seems a waste, using a 12" only for freqs above 120Hz, but......    https://www.madisoundspeakerstore.com/index.php?p=home

Hello,

First thank you very much for your fast response ! I wrote down all the specs of my system. My intention to use SB Woofers is have a passive bass in my system due to lack of bass in Peak Consult Grande.

Pre Amp* - Audio Research Ref 5 >> Power Amp - Audio Research Ref 210 x 2 >> Speakers - Peak Consult Grande

Pre Amp* - Audio Research Ref 5 >> Subwoofer Power Amp - VTM 200 x 2 >> SB Acoustics 12’’ x 2 (passive bass)

*Same Pre Amp feeds the PowerAmps.
