Thanks, is it a case of up to an inch of adjustment on fine tuning? Obviously I won't know until its measured but do you have any idea what range it may effect? Thanks again.

At 22m/s, you are going to see some vent compression effects. This may not be readily audible however, unless perhaps you're playing test tones.

The proximity of the inside end of the vent to the nearby walls will lower the effective resonance frequency a bit. Be prepared to measure Fb and to trim the vent if necessary.

Yes it does! I am just getting the hang of bass reflex at the moment. I'm On my fourth build. Would this attempting too much to adapt that design?

It looks very compact and girlfriend dictates I can do what I want it just can't be ridiculous. lol

Yeah, they look really interesting, thanks! My girlfriend might not approve. Compact is an element.it has to be under 60cm tall to fit in.

The anarchy tapped horn looks very interesting. I will compare my drivers with the Anacrhy drivers. Do you think there will be the need for a lot of adjustment ind esign to accomodate my drivers?

Don't forget, it is 22ms at full power. Driver might be limited by Xmax.

You can try my SpeakerSim, which simulates port velocity at maximal power (according to Xmax).

It will push Fb lower, how much lower its hard to say. Just make the last section removable so you can easily trim it.

Thanks, yes very detailed.

I'm starting to wonder from other peoples projects if I really need two dual subs since this driver is a little weapon. I have the TB 5.25" driver in a BR box for my kitchen and it is might big for its size but I want subs that I don't need to push to hard.

This project looks very tempting to me. I think I will build my dual sub but maybe later one try these cabinets for a stereo config.

The Tangband 38Hz Tapped Horn – Volvotreter Homepage

My queries in regards to this are as follows:

He mentions "Note that the design includes the use of 4,7mh coils to even out the response. They are wound from 1,32mm dia. copper wire and have a Rdc of 0,26 ohm."


How are these implemented and what is he smoothing out?

The response looks funky after 100hz, I usually cross my subs over at 120hz for a bit more upper thump in my system. Is this no-mans land for the way I would like to use them?

Also, are the drivers trapped in the design once they are sealed up? I'd like to have flexibility to move drivers from different cabs in the future?
