3G_ Posted May 14, 2013 Posted May 14, 2013 Looks beautiful, but i do wonder about the room acoustics

3G_ Posted May 14, 2013 Posted May 14, 2013 Yum! Didn't realise the Americans invented horn speakers! Lol! The Americans invented everything, didn't you know :0
ehtcom Posted May 14, 2013 Posted May 14, 2013 The Americans invented everything, didn't you know :0 Anything worthwhile that is. Everyone else just copied them.
Zaphod Beeblebrox Posted May 14, 2013 Posted May 14, 2013 Anything worthwhile that is.Everyone else just copied them. Karl Benz (Of Mecedes Benz) is considered to be the inventor of the modern, internal combustion powered automobile. The Septics copied him.
tuyen Posted May 14, 2013 Posted May 14, 2013 Yum! Didn't realise the Americans invented horn speakers! Lol! Were you talking about the funky women undergarments or the horns mate??
Upfront Posted May 14, 2013 Posted May 14, 2013 Are you suggesting I like to wear finicky women's underwear??
tuyen Posted May 14, 2013 Posted May 14, 2013 Good. Now I know what to get you for xmas. hrmm.. have found suitable bass horns to pair with YL D-1250 compression bass drivers. They are for sale too. http://www.audioasylumtrader.com/ca/listing/Speakers-Horns-Parts-Stands/Bass-Horns/Custom/for-Ale-Goto-Altec-etc/53636
ehtcom Posted May 14, 2013 Posted May 14, 2013 Karl Benz (Of Mecedes Benz) is considered to be the inventor of the modern, internal combustion powered automobile. The Septics copied him. 1872. In America George Brayton invented Brayton's Ready Motor and went into commercial production, this used constant pressure combustion, and was the first commercial liquid fuelled internal combustion engine. Brayton cycle engines were some of the first engines to be used for motive power. In 1881 John Holland used a """Brayton engine""" to power the worlds first successful self propelled submarine, the Fienian Ram Also the Selden auto of 1878 used a Brayton cycle engine. More on Selden. He filed for a patent on May 8, 1879 (in a historical cross of people, the witness Selden chose was a local bank-teller, George Eastman, later to become famous for the Kodak camera[3]). His application included not only the engine but its use in a 4 wheeled car. He then filed a series of amendments to his application which stretched out the legal process resulting in a delay of 16 years before the patent [4] was granted on November 5, 1895. Whilst Benz did commercially produce the first internal combustion engined automobile (1885), he was using technology already available.
Upfront Posted May 14, 2013 Posted May 14, 2013 More importantly Earle.... Did his "wheeled chair" have a horn?!?!

peterstt Posted May 16, 2013 Posted May 16, 2013 Tuyen Take a look at "TwoGooears"'s blog.---Elodis" Vcalitas maclina Grandis". A bass reflex cab for the GOTO SG38WN.
tuyen Posted May 16, 2013 Posted May 16, 2013 Thanks for the heads up Peter! hrmm.. ported box.. that was what I move away from! I must communicate with Stefano and hear his impressions of using ported box. For me, I currently prefer front horn loading the SG-38WN. What's your opinion on how to use the 38 woofers?
peterstt Posted May 16, 2013 Posted May 16, 2013 If all design correctly, front loaded horn is always better than other type of cabinet. Only take up more real estate and need skill to integrate the Mid and High units. How is your mid-bass horn performing?
davewantsmoore Posted May 17, 2013 Posted May 17, 2013 Is there an ULF channel?.... If not, then perhaps maybe BR makes some sense (?!?!) Otherwise. Sealed. If we want bass then use horn, EQ or both... do not use a resonant mechanical system.
tuyen Posted May 27, 2013 Posted May 27, 2013 (edited) There is Dave. Using a single 12" rythmik direct servo sealed sub to fill in the <60hz band. Running just 3-way setup now. bass horn between 60ish-hz (natural rolloff) to 350hz (24db cut with the Rane AC22 2-way electronic crossover unit), midhorn doing 350hz (with 24db cut with the Rane) to 6khz (6db cut with passive inductor), tweeter rolled in at 6khz onwards using a single cap. Yamaha P2050 pro series studio amp driving the bass horns and LM3875 chipamp driving the mid/tweeters. Checking out a DIYhifisupply Tram2 DHT valve preamp at the moment. Not bad. Edit: just realized I am running it 4-way, if I include the active sub. Edited May 27, 2013 by tuyen
3G_ Posted May 27, 2013 Posted May 27, 2013 What is the difference in sound without the mid high driver? Do you miss it?
tuyen Posted May 28, 2013 Posted May 28, 2013 subjectively? or do you mean measurement wise? I don't really miss the mid-high channel at the moment. I did have system running 3-way a few years ago when I had the 160hz l'cleach horns instead of the 200hz goto s-200b horns. I remember doing a comparo with the system in 4-way mode with midhigh channel in (goto sg-370 midhigh + goto s-600b horns) and then 3-way mode, removing the midhigh and running the midlow channel (goto sg-505tt + azurahorn 160hz horns) higher (5-6k). All done actively with Pioneer D23 electronic crossover, so couldn't blame my lack of experience or know-how with building passive networks. Removing the mid-high channel improved overall coherency and increases the scale of 'openness'. I did notice a reduction in image focus/sharpness though. Slight dip of response around the 4-5khz range as the goto sg-505tt midlow driver in the horn starts dropping sharply at 4khz. Found a vid I made of system in 3-way mode. I miss the big l'cleach horns. Music had serious 'live' factor, no conventional box speaker I have heard before can replicate.
3G_ Posted May 28, 2013 Posted May 28, 2013 Interesting Tuyen, thankyou. I have the Yamaha 6681 in a 340Hz LeCleach and the Fane 8M in a 160 Hz LeCleach. I am thinking of using the 6681 down to 200Hz in the big horn as I am building a 16Hz concrete Bass horn for a 18" B&C driver, which on paper will do 20 to 200 flat. Considering a GOTO SG 370 in the 340Hz horn?? 1
tuyen Posted May 28, 2013 Posted May 28, 2013 Very cool and good luck with the bass horn! The GOTO SG-370 driver was designed as a midhigh driver to play between 1-5khz (6db cuts). Recommended to be paired with the S-600B horn (600hz). From my experimentation, the driver can play to only about 7k, until it starts sounding a bit 'hard' and affects the overall 'naturalness' factor that the goto drivers are known for. What freq range are you wanting to drive with the 340hz horn ? Maybe a one of the goto mid-low drivers would be more suited?
tuyen Posted May 28, 2013 Posted May 28, 2013 There is a pair of GOTO SG-570BL midlow drivers for sale in the UK if you were interested. Not exactly cheap though. lol http://app.audiogon.com/listings/full-range-goto-sg-570bl-compression-drivers-2013-01-03-speakers-uk
