SEAS FEA18RCZ in TQWT, need some quality control :)

Is it someone who can quality control my simulations here? 🙂

I use AJ Horn (newbie) but i assume Mathcad from M J King would do the same?

I haven't used any stuffing in HornResp in the 46 litre version (assuming my interpretation ok) so there is quite a bit of midrange resonances to be tamed. You could try comparing against similar/different volume tapered TL, sealed and bass reflex to see if anything is gained.

It needs stuffing. In my simulation i have filed the front with 40% i think.


I havent testet the driver yet but i must definitely have a baffelstep filter.

After what i can see from the specs it isnt the easyest driver to work with. I will try with impedance correction and notch filter aswell.

Here from Seas aplication note:

I ended up trying out a bsc filter on my fullrange small TLs using one of the calculators-likely MJKs. I gave it about 3 months of trying different listening positions while the driver settled in before hand. It’s probably something I should re-evaluate now after 3 years to check if it’s still required.
