I am happy to go ported too by the way. But equally i want to know the CORRECT way to work out enclosure size. As keep reading conflicting formulas.

Sealed seems more easier for first timer though and i prefer the pros of a sealed enclosure.

But after you saying 10" reflex id be happy to give that a go. Need info on the port size/length and ecnlosure calculating though man 🙂👍🏼

We often use a single tham 12 per side with either a small 8 or 10 + 1 reflex cab for smaller gigs and two thams per side and a single 10” + 1” reflex for larger gigs, the 10 + 1 seems to keep up very well.

You may find that a sealed mid will NOT be able to play low enough to reach the tham without the a large box as the thams are only any good up to about 120Hz.

My mid/tops are only about 22 ltrs (0.777 Cubic feet) and are tuned to about 73 Hz with 98db/w output. They use a cheapish fane sovereign 10-300 driver.


Thanks APW appreciate the feedback man. All taken on board 🙂

My question is still unanswered with the way to work out enclosure size though so if i did go with just 1 mid i still dont know how to calculate it? Any pointers with that? As you can see the 2 different outcomes from 2 seemingly good sources

Heres info from another forum someone posted for finding PORTED ENCLOSURE size. He does then say to reduce that size by 20% for a Sealed Enclosure (not pictured in the screenshot i know). 



So if i used this information my final size would be 1.87ft³ which is very different to my previous volume. This is why its confusing me.

I want to build a double 10" mid range sealed speaker enclosure. I have been thinking of using these speakers 
If you have other suggestions of driver or what to look out for when choosing a midrange driver let me know. I have been going by frequency range.
They will be used with 2x Tham12 subs. And 2x tops.

Ive been reading and reading mixed information and also downloaded winisd but i cant get my head around it. I want to build sealed mids as its easier for my first time. I wrote driver details in on this site and this is the results:


So i assume i now just double that VB figure and then add the speakers displacement on top of that to get my final internal volume size? If so my final volume would be 1.16ft³. This figure just seems far too small to me though, so i feel like there must be more to it??

Any help would be great cheers 🙂👍🏼
