Scan-Speak Flow Resistor Aperiodic Vent - EACH

Cutout size is 4.3 inches.

Product picture demonstrate the front and back side of these vents. They are sold each, so order two if you require a pair.

Aperiodic vents lower the Q of your driver in a sealed box. They essentially makes your sealed box woofer act as if its in a box that is roughly 20% larger. We recommend using one vent for boxes up to 1.5 cubic feet and two vents for larger speakers. If your box is really undersized or if you are using a large woofer in a small box, you could use two or more, to help reduce pressure in the box.

Also known as the "Scanspeak 130mm Flow Resistor #290001".

'These are perfect for vintage full-range speakers without TS parameters. I got a good result with a pair of vintage Philips 800 ohm high-impedance FR drivers. 5 stars for their customer service.' Review by James Jung. Posted by Madisound.

'Not had chance to fit these yet, but I just wanted to compliment Madisound on the excellent customer service I experienced when purchasing these vents. I live in the UK and they are not available here so Madisound was the 1st place I found them. They just arrived; I only placed the order 8days ago-not bad from the States! What really surprised me was the shipping cost Madisound emailed me AFTER I'd agreed to pay $29.99 to ship them to the UK and told me they'd do it CHEAPER! I really couldn't believe it-even when they had the chance to make a few extra $ ($14.00 to be precise) they still had HONESTY to advise me the y could ship for less and the DECENCY to do it. This really speaks for the ethics of the company and I have no doubt I will order from them again and recommend them to all and sundry!' Review by GREG BARNES. Posted by Madisound.
