same64 Posted July 9, 2017 Posted July 9, 2017 Waiting for Little tube amplifier only 4watts and was planning to use with some full range drivers i have but maybe some high efficient vintage speakers would be an good option. I don't really have much experience with vintage staff and don't want to spend to much (might get bored quickly) up to $500. Maybe some advice from you guys would point me to some vintage speakers that would work well with 4watts and sound OK . Room is medium size. below that impulsive buy. cheers 2
Happy Posted July 9, 2017 Posted July 9, 2017 Actually vintage might not be such a good idea when it comes to high efficiency speakers. Most cheap ones tend to be from the monster receiver era which are the opposite of HE. The good stuff, Altec, some Diatones, Klipsch, early JBL all tend to command prices well over $500. Your most economical way would be some secondhand DIY full range attempts.Sent from my iPad using Tapatalk
mwhouston Posted July 9, 2017 Posted July 9, 2017 (edited) That amp will only produce 2W before lapsing into high distortion though not audible. You require at least 94db speakers to provide good listening levels. Get a pair of Fostex 8" drivers and make some boxes for them and you will get good volume and sound. A pair of Fostex will cost you around $350 and can be purchased from a Ozzie supplier. They will produce reasonable bass and good volume for under $500. No Xover required. Message me for more help if required. Edited July 9, 2017 by mwhouston 1
same64 Posted July 9, 2017 Author Posted July 9, 2017 Thanks guys I have Mark audio Alpair 10.3 in Onken boxes but that its not efficient enough.Anyway i will test when i get the amp. Thats why i thought about vintage .Would that all staff from 70s like pioneer be any good?. BTW Mark where you can get Fostex from Ozzie supplier?.

mwhouston Posted July 9, 2017 Posted July 9, 2017 @same64 no guarantee of efficiency. The vintage high efficiency gear will be very expensive and doesn't always sound that good.
GhostCoast Posted July 9, 2017 Posted July 9, 2017 4 watts puts you in a very difficult situation.. it is not easy to find speakers that can excel with that.. 10wpc would have been another story..
mwhouston Posted July 9, 2017 Posted July 9, 2017 I've built quite a few of 2W and 8W tube amps. The only way to get good volume is with high effciency drivers. Vintage Altecs usually exceed 100db of effciency but are expensive even very second hand. My DIY Beyma 15" concentrics are 99db efficient. The inner tweeter second is 105db efficient. With 2W they play very loud. Even my 1/3W (330mW) 1920s tubed DIY amp plays loud through them. 2
mwhouston Posted July 9, 2017 Posted July 9, 2017 15" Beymas http://retro-thermionic.blogspot.com.au/2016/03/voxgrandious-beyma-high-efficiency-15.html 12" Beymas. These are for sale but a lot more than $500. http://retro-thermionic.blogspot.com.au/2014/07/voxconcentric-beyma-12-high-efficiency.html
mwhouston Posted July 10, 2017 Posted July 10, 2017 I see you are in Vic. Open invitation to bring the amp down for a listen on the Beymas. I think you will get a shock (the nice kind) when you hear how loud it will play. Also I can test you tubes if you like. I'm not far from Frankston just 15mins inland. What are the power tubes; EL34s, 6L6s or 5881s? 2
MattyW Posted July 10, 2017 Posted July 10, 2017 I've had excellent success with Dayton USA PS220-8 full range drivers. Sound incredible for the price. They're 96.5db efficiency. Cheaper than Fostex too [emoji6] Available from Parts Express or eBay Sent from my Redmi Pro using Tapatalk 2
MattyW Posted July 10, 2017 Posted July 10, 2017 Sure thing https://www.parts-express.com/dayton-audio-ps220-8-8-point-source-full-range-neo-driver--295-346 I use these in my secondary system, which annoyingly sounds better than my main system despite being 1/4 (or less) of the cost. The main can make crap recordings sound good though so I forgive it Check on eBay also as shipping is often cheaper on there despite it still coming from Parts Express Sent from my Redmi Pro using Tapatalk 1
GhostCoast Posted July 10, 2017 Posted July 10, 2017 that driver looks quite promising.. you could use duals and get an extra 3db efficiency at 4 ohms 1

mwhouston Posted July 10, 2017 Posted July 10, 2017 @MattyW this driver looks great. Excellent efficiency. 1
MattyW Posted July 10, 2017 Posted July 10, 2017 Yes, with my little 10W Oldchen SEP amp it can reach party levels in a largish second living room. Will be interesting to see how things change when I go to monoblocks and a passive pre [emoji4] If you're in Brisbane I could arrange a demo sometime. Sent from my Redmi Pro using Tapatalk

Size of the driver doesn't necessarily determine the level of the ease with which to drive it. Just look at old Altec 604s they're huge yet can be driven by a mere 2a3 SETSent from my iPad using Tapatalk 2

What enclosure you have for Dayton ?. BTW that 10W Oldchen SEP amp is that good ?There are lots of good reviews on the net. cheers 1

I use to experiment with open baffle and build Linkvitz Pluto clone and few pairs of small full range drivers as well.But this time i want play a bit with vintage speakers. I don't want Ferrari:-) . Pioneer and Sansui have build few good amps and im sure that some of the speakers were not all bad. Just checked Altec 604 ,it is big:-) 2
MattyW Posted July 10, 2017 Posted July 10, 2017 Yes, it's a really incredible amp not even factoring in the low cost. Matching this with the Dayton PS220-8 makes for a cheap a amazingly good sounding system. The only downside is that a quality line switch box costs near as much as the amp. Soviet era tubes also make a large improvement over the Chinese tubes it comes with stock. The Daytons sound a bit bright and harsh prior to break in though are now my favourite speakers. They take a fair while to break in though. I have the Daytons in some 60's vintage custom cabinets which unusually for the era are vented. I removed a pair of high efficiency Plessey Rolla Alnico drivers. Amazing sound though just lacked detail. If anyone wants the drivers I'm happy to send for the cost of postage. Would sound great paired with some Air Motion Transformer tweeters I'm sure [emoji4] Here's a picture of the cabinets Sent from my Redmi Pro using Tapatalk

mwhouston Posted July 10, 2017 Posted July 10, 2017 @MattyW would you put up an image or two of the Plessy drivers. Are they 8" wide range also?
