TB 1808 plus H-frame

[Godzilla]

I have been enjoying the the TB 1808 on open baffle sitting on top of H-frames. This is a revealing speaker with a forward midrangy sound that's open and detailed. Overall I am very pleased with them. The super tweeter has a cap value of .69uf and nicely blends with the 1808. If you like your vocals pushed forward and intimate you will love this driver. It's fatter in the mids than the Fostex 165k and 168s (older style with whizzer) and less bright on top. The 1808 has detail galore. On open baffle there is a jump to the music that adds a life to the overall presentation. Imaging is excellent, very 3D. This is my current favorite full range driver but it does favor mids. I think it works very well all by itself in a ported box (soft at the extremes) but I enjoy the H-frames so much i can't seem to get enough of them. For a while anyway, i expect to keep the H-frames for bass duty and play around with drivers on open baffle.

Hey Zilla,
Those look super and ez to build
Tell me,what subs and tweets

[Godzilla]

Thanks bigfishe, those are old Radio Shack super tweeters i had sitting in a box for the past several years. I thought they would suit the purpose and they do. I have another pair of them facing backwards on a pair of BIBs too. The woofers are Eminence Alpha 15's in H-frames powered by a dedicated amp. The whole thing gels nicely providing very involving sound. I built something to sit on the H-frames so that i can swap baffles in the future easily. For now the TB's get their turn. Separation and imaging are very precise. Left and right are beyond the walls and center is dead in the middle. Not sure if it's the drivers or the open baffle setup but the imaging is really impressive. I have Pioneer B20s, Betsy's, a few Fostex and those inexpensive Dayton 5" drivers i want to make baffles for just to see how well open baffle works with less expensive drivers.

Lovin it Zilla,I have the same tweets from the 80s
And would like to try the whole OB thing
Do you think the Pyle pro 21" sub work in OB or H frame?
Part # 21250

Nice Jeff

Do you still use your 18'' Goldwood H-Frames for anything ?

[Godzilla]

I never had the pleasure of listening to the 18" Goldwoods and don't own them. But having two 15" woofers in my system for a while i understand why big drivers are better at making bass. As for the Pyle 21", i could not find specs on it (no qts anyway) but would be pretty certain they make bass in any kind of enclosure. I can't imagine having two 21" drivers in anything but the largest rooms.

As cool as this full range driver thing can be (great mids, less listening fatigue, etc.) I think BASS also contributes in a big way when i sneak into the basement for a listen.

Nice work Jeff!

It will be interesting to hear how different fullrangers perform on Open baffle without spending a fortune. It will be interesting to test smaller fullrangers (3-4") compared to 8". Tb-1808 might need a dip in the midrange, or a hi-pass crossover may need to be set a tad higher. Nevertheless, it's a big playground and may keep you entertained for a while.

>>> It will be interesting to hear how different fullrangers perform on Open baffle without spending a fortune.

I have the Fostex 127e, TB Bamboo 4" and Dayton 5" full range drivers. I wish they had the same hole cutout bc i want to compare them. Cheaper drivers may benefit greatly on open baffle when bass duties are placed somewhere else. Imaging quality is different on open baffle compared to box speakers. What doesn't work in a box may work great on ob... no worries of low frequency tuning or box colorations... just a driver free to breathe. State of the art may require expensive drivers for that last bit of realism but cheaper stuff may be very enjoyable. I'd love a cheap open baffle system that sounds wonderful! It's like owning a nice VW and not having to worry about dings in the parking lot.

I'd like to hear a set up like that some time. Nice work.

I'm sorry, I had thought for sure you built the GW 18's and that's what got me on board with them.. Now whom did I go and confuse you with lol.. Me thinks age may be taking it's toll on my otherwise previous lethargic condition anyways
