MLTL for "Hemptone" FR8? Pretty Please.

[Scottmoose]

Agreed. GM's will ultimately be the more capable enclosure (bigger is better) once tweaked to your taste / room requirements. OTOH, mine will be closer to a 'plug & play' box in a smaller space, so as ever, YMMV. Frankly, if you don't mind juggling the vent dimensions a bit to tune to your room, then I'd build Greg's.

My place is a little bit small, 10"x25" so maybe I must go with Scott's? What do you say?
The difference isn't to big though............. GM's isn't too much bigger

Just in case, I'll build GM's, the only tuning is the port's length?

[Scottmoose]

Right. Increase the length to roll it off if you feel the bass is a little heavy / boomy due to it overloading your space. 10ft x 25ft isn't what I'd call 'small' though -by UK standards that's a pretty decent size.

Due to the new thread that has been posted about Hemp's "non pure Hemp" construction I'm thinking not to buy a Hemp driver ,yet. I'll wait until the company will standarize their products......

So what about a wide baffle MLTL with FE207? Or MJK's MLTL?
I need bass that's why I have stucked with an 8". If you believe that I'll have enough bass with a 6.5" and better mids than the 207, not a problem..... please help!
I CAN"T DECIDE WHAT TO BUILD

Scott,
Do you believe that my room has a pretty decent size for a BIB?

[Scottmoose]

Heck yes! You've a choice really -6 1/2in or 8in units, though I'd limit the height of the cabinet in both cases to 70in or you might things a little lively. And they'll cream any MLTL on dynamics, which FR drivers can always use a helping hand with.

FWIW, I'd probably go with the FE168ESigma. Use the Sl dimensions I posted on the Zilla site, but increase line length to 138in (70 in tall cabinet) and Zdriver to 30in. Job done. I love the FF165K too, but it's better suited to smaller rooms, so the Sigma would be my choice of 6 1/2in driver for your environment. Alternatively, if you want an 8in driver, the FE207E, again same height & driver position as mentioned above, with the Sl dimension off the Zilla site should be OK.

Greets!

So many choices, so little time.

If you have a closet you have a big enough space since a pipe horn has gobs of tuning flexibility, though obviously you reach a point of diminishing returns WRT usable Fp. Anyway, ideally you'll put them in the corners of a 10 ft wall and sit ~15.45 ft away. With no major room gain kicking in until the 20s, I'd stick with the 8", though all things considered, one of the HE versions seems a better choice.

Build a Hemp in a BIB was my first choice. But when I realize that I need a cab around 20" deep (minimum) I thought that they're too big for my room.
Also, the distance btw the drivers will be around 5.5-6ft.
I'd like to place them as far as possible..........
Now my ME2 (ariel) are at 6.6ft.

[Scottmoose]

Well, the hempster might be a trifle large, aesthetically speaking. That's a taste thing though. OTOH, the Fostex 8in range don't need such a big enclosure, so the 206/7 or even the 208ESigma (with additional supertweeter as it's a WR rather than FR unit) should suit you nicely & they've loads of excursion too. Fostex have not built up their formidable reputation by building poor drivers. Follow GM's advice -believe me, he, er, knows what he's talking about. And then some.

[resident]

Ok what do you say to go with the FE207? (or the 206? - which arethe differences?)
Not a too big BIB and a good choice for an 8in.
Also if I can live with them in my room I can go with bigger ones in the future.
Hemp's are good as said but with what is going on right now with the cone materials I'm a little bit afraid to buy them.
I'll wait for a Tone Tuby...........


P.S.: We got a little bit out of topic in this thread. I'll post new messages in the BIG TC's BIB thread................
Sorry to the author

Well, I recommended a HE 8" as a compromise between LF output and the 'magic' of a smaller driver's mids/HF, so for Fostex there's only the FE206E, FE206ES-R, FE208ES AFAIK and I don't have any personal experience with these, so you'll have to rely on others for mid/HF performance opinions.
