Hi!
I'm contemplating building a speaker with a 12" or 15" - a bit like a Tannoy Arden if you will - and am wondering about the ports: If I have front-facing ports, will there be a risk of hearing higher frequencies from the ports as "ghost" tones? The crossover frequency would probably be somewhere around 1500-1800Hz.
Cheers

I can't recall any studies on this subject, but you'd think adding plenty of stuffing would help reduce it.
Don't know about 'ghost tones', but front facing ports may emit some unwanted midrange frequencies.
As fatmarley says, the way to mitigate this is by the appropriate use of internal absorbent material.

Put the ports on the bottom and the enclosure on small legs.
Do NOT build the enclosure like an Arden; it's an unbraced resonant piece of ****.

I do realize that - hence the "bit". Please read "a bit like a heavily braced Tannoy Arden" 😉
