You had me real excited for a bit.

Whoops, I did not mean the SB29NRX75-6 but the SB29SWNRX-S75-6

According to this calculator: Speakerbuilder Pro 2.0


SB29NRX75-6 (midwoofer) 36 Liters Closed box (Q=0,707)

SB29SWNRX-S75-6 (subwoofer) 14 Liters Closed box (Q=0,707)

I use a pair of SB29SWNRX-S75-6 in a closed box around 18 Liters. Works very well with a little bit of DSP (no problem playing 30 Hz). They can play even lower if that is what one wants. And they can be pushed hard! - High x-max and low Fs. The advice using them in a small cabinet was given by the engineer behind the driver. I made a little bit bigger cabinet because I used a spare-cabinet from a previous build.

For the asking price an outstanding driver IMO.

Yes probably but If I remember correctly not HF but HO is better for small sealed. I don't want to be too much-optimistic about Dayton drivers but from my 'sims' it seems whole RSSxxxHO 4 ohm series is among the best out there for such specific purpose. Black anodized aluminum cones as a bonus.

I will post updated list and add some simulations later

I would stay away of them. Ordered a 26W/4534G00 and waited for it for two and a half months. Then I saw they have a dedicated thread on here and I`ve been lucky to get mu stuff in 2 and a half months only.

Same, ordered parts from europe audio/loudspeakerfreaks and after waiting a few months and no reply asked my bank to make a claim. As a result the order miraculously turned up a week later but I'd moved on to another project by then.

So shame, I wanted to drop them an order for fair amount of DA drivers but you guys thankfully warned me on time. Hard to obtain these all drivers frome one source in Poland and in EU, unfortunately... Now Let's back on topic please and seek for efficient and linear air pumps for bass from compact boxes

I ordered from them once. Order tool 1 month instead of 1 week. They sent 0.82 Ohm resistors instead of 1.5 Ohm. On the other hand they also included extra stuff on the order. It was alright in the end.

Thanx, that one works. Now i have something for a Frugel-Horn XL deflector/stealthWoofer.

Sims show Q=0.707 F10 of <30 Hz in ~16 litre anechoic.
