I am looking for affordable 12" drivers to replace the Peerless 831812 used in the Gradient SW-63 dipole subwoofers. The alternative replacement - 831857 and 830500 - are no longer available, they are discontinued. Make is unimportant.
Hi Mark,
Thank you for your prompt reply. The Peerless 831812 has been discontinued for a long time and the suggested replacements are the 831857 and 830500, they are out of production too. I checked my Peerless catalogs and found data for the 831857 only, please see attachment. The subs have H-frame enclosures, these subs need a 6dB/octave boost because they are dipoles. Acoustic Elegance is a speaker company that has taken over Nick Mcinney's design after his death, the fantastic Lambda 8? SB12. But AE speakers' close equivalent, the Dipole 12-D8's price is outside my range at $339 a piece. [fs is high]
Cheers,
Horacio
Hi Mark,
According to AE, the IB series woofers are designed specifically for automotive infinite baffle applications.
Nevertheless, I should have posted the crossover specifications first in order to produce a spreadsheet with parameters that match MT Audio Design's recommendations? The XO-2001 is far superior to the original Gradient crossover. Unfortunately, the Swedish company is no longer in business.

May I suggest to check the 2001 specs?
I have a very simple two channel system - Klyne 6LP3X/Linn LP12/Ittok LVIII/Denon DL-103R/Meridian 507 and Revox A77 15ips. I want to run the subs with either my superb Electrocompaniet Ampliwire 100 DMB [125W/Ch] or a pair of recently upgraded and bridged QUADs 405-2 [180W].
Kind regards,
Horacio
Hi Mark,
John kindly simulated a large open baffle that gave me an idea of what I may have in the H baffle design. He says that the Dipole12-D16 would be the best possible option. The plans that I have for the cabinets are an exact copy of the Gradient SW-63 enclosures but I am not sure if they would be a good match for the 12D-16s, it would be great if they can fit that design.
Attached are the plans for the cabinets.
Best regards,
Horacio
