Interesting thread.
I'm also not really satisfied by the Viech.
Mid(bass)/high of the 8 AG/N isn't unusable though, I rather like it in combination with a sub as 'party speaker'.
When I find a good (+ low €/$) woofer to accompany the 8 AG/N I guess they'll end up as woofer assisted FR's.
But for now (don't own a decent sub, only a Logitech '2.1' computer set..) how what do you gentlemen think of this;
BR
Volume 60L
FB 40Hz
Port dia 10CM (L 17.224CM)

Well, based on the available specs, I like mine better 😉 just because it's bigger, but I see nothing fundamentally wrong with yours either.
If the Logitech is on a par with the Creative 2.1 I have 🙁, the less said the better.

No, I normally just 'run the numbers' for simple sealed, BR alignments. It just so happens I have a MLTL from several years ago with the same net Vb though and due to its high aspect ratio and moderate stuffing density the vent need only be baffle thickness:
L = 59.3"
WxD = 145.7"^2, suggest ~ 15.36" x 9.5"
zdriver = 22.06"
dport = 6"
zport = near/at the bottom
All dims are i.d. and approximate.

I still can´t quite understand how the heck can I manage to get much better bass than in the viech...I mean it´s no subwoofer bass,but it´s there!Lean recordings sound lean,but a good recording with bass lines will shine on them!
'Better' is in the ear of the beholder and if its specs are even remotely close to those Scott and I have, then at a glance it seems you like your bass much more resonant than we do. 😉 Then there's the room's and signal chain's effect on the sound, so without being there there's no way to know for sure what's going on. From your description though, it sounds like the Viech is a pretty good design with a performance more in line with what we like, i.e. just reproduces the signal (good or bad) with minimal distortion.

well,I like the dry analitic sound the viech produce,it´s just that sometimes it sounds like there´s no depth to the bass.I´ve been to some concerts and surely some bass guitars sound more...well,deep! 😀
I listen to all sorts of music,and I´m not a bass addict,but sometimes and most of the time,really,bass just isn´t there...and I´m a reasonable guy! 😉

Don't really know what to say, not being there or being you. FWIW, when I started out, most recorded music didn't have much energy below ~60-75 Hz depending on the signal source, so a 40-80 Hz tuning was 'HIFI' and yet, the larger the cab and the lower I tuned it the more realistic it sounded until around 25-30 Hz in a very large net Vb there was nothing there except on a few special effects RTR tapes.
Deep bass then was predominately what we now call mid-bass and why a BP such as the Karlson can sound so real in some ways on many recordings because it strongly emphasizes this BW.
As recordings increased in BW, the cabs either got lower tuned or bigger and lower tuned until today if it's not tuned to at least 16 Hz it doesn't interest me and with some movie soundtracks it needs to be down in <10 Hz range. If for space/whatever reasons requires a smaller cab/higher tuning, then a high pass filter should be used to protect it from excessive amplitude modulation distortion (AMD).
I haven't reverse engineered the Viech, but the BLHs I've auditioned fall into two categories, either they are highly resonant (overly lively) or over-damped (too analytical) with precious few sounding 'real' and only a couple going low enough to cover most music, so unless it's quite large it probably unloads to high to extend beyond the mid-bass.
In this respect, your BR shouldn't fare any better, so am at a loss as to why you consider it a better performer unless it has to do with it having a bit of built in BSC in the form of an under-damped alignment that the Viech may not have due to the designer trying to keep as small as practical, a common problem with most horns.

BR needs more displacement than most fullrangers have. 8" Tangband 1772 works, I have seen it in a magazine, but is expensive.
hm has plans for "double horns" that go very low with small fullrangers.

well,I can´t beat knowledge that I´m found lacking but unless I did anything very wrong with the viech´s (poor damping,construction,etc),I still prefer the ressonant bass that the beymas produce in this non optimized BR test enclosure,and most importantly,the inlaws love it!(and this was something I made for them...)
Any way,coping with the viech´s,I´ve been trying to tune them as best as I can,but no matter how pillow stuffing I´m using to keep the mids comming from the driver,they´re still being expelled through the horn mouth.
What do you guys advise regarding this problem?I want to keep some of the bass and stop mid frequencies from comming from the horn mouth.
