[quote name='bassmayhem' timestamp='1402777203' post='2476775'] If you have a preamp with a single output you'll need a split Y-cable so you can send to both inputs on the power amp. I use it for stereo rig konfiguration. [/quote] Does your PLX not have the parallel input option on the dip switches? My PLX1602 has this option which means you can use input A to drive both power amps in a stereo setup.

Holy cow batman! Whatever that cost, it isn't enough. That finish is simply stunning, reminds me of the early Washburn's. We need a full final run down of the control layout - it certainly looks interesting.

[quote name='bassman7755' timestamp='1401475907' post='2464075'] Worth remembering that the master volume setting doesn't intrinsically limit the power of the amp, the amp can still deliver its full power if it gets a hot enough signal from the preamp. [/quote] Indeed. This is why I'm conservative on both 'masters' i.e. half on the QSC and half on the SWR. I also use the compressor on the SWR to clean up any nasty 'player dynamics' i.e. cock-ups I may make :-)

I'm four gigs in to my pre/power amp setup and so far, all is fine! I've gone with the SWR Marcus Miller pre into a QSC PLX1602 to drive (in bridge mode) my 6x10 mini-fridge. Because the mini-fridge is 'only' 1,000w 4 ohms nominal, and the QSC puts out 1,600w @ 4 ohms, I run it with the QSC on about half with the SWR master acting as er the master! So far, this rig has done two pub gigs, one outside gig (pub beer garden, no PA support) and a large bike rally (with PA support) and has handled them with ease. Weight-wise, racked up together they are a one-handed carry (as against the SM1500 that was a two man carry). Also, the amp appears to handle transients and low B stuff better than the SM, it's more immediate and less of a delay waiting for the note to develop.

[quote name='bassman7755' timestamp='1400836265' post='2457340'] I used to be obsessive about lows being a 5-stringer and wanting some "fundamental" but using a QSC amp cured me of this as I could play around with its HPF which could be off-25hz-50hz. I found that even the 50hz setting made no audible difference even on the low B other than the absence of excessive speaker cone movement. [/quote] I can only echo what Bassman7755 says here. I've just moved over to a QSC powered rig and currently run it with the low cut filter set at 50hz. The sound difference on the low B is negligible and even less so 'in the mix' on stage. The lack of excessive cone movement is however reassuring. Looking at our set list, most of what we play is in either A or D with an occasional trip down to G. Accordingly, the extreme low end is of less importance than the low end of the mid range as its this that I'm trying to pick out from the mush of guitars and drums on stage.

That carving is looking pretty tasty mind! I know what you mean about the sanding but there really is no alternative. Are you going to use a grain filler or just a sealer?

[quote name='VTypeV4' timestamp='1399677181' post='2446715'] Very cool.. Power and control, just hope your speakers are up to it! Ha [/quote] I hope so too! Tried it at rehearsal last night through my 8ohm 4x10 (1,000w) and it sounded lovely, to the point where I couldn't differentiate between this and the SM1500. Gigging it on Sunday through the 6x10 so we'll see how that goes. Based on last night, and I can't believe I'm thinking this, but the SM1500 may have taken one step towards the door Oh and now nicely flightcased up and ready for the road [IMG]http://img.photobucket.com/albums/v208/JPJ/IMG_1034_zps70de4e44.jpg[/IMG]

I wouldn't chop the cab as you'll alter the volume (cu ft not watts) and in doing so you will anger the bass gods. Your cab has top and bottom ports, whereas the wedge only has a top port so, if you cut the back corner off, you'll probably have to modify the port 'shelf' as well to avoid choking this when you fit the angled bit back on. I'd go for a small stand or even make a pair of elongated x shaped 'stands' and attach them to the cab using the holes for the rubber feet. That way, it'll be possible to revert to the standard cab at anytime.

As a confirmed SWR nut, please enlighten me as to the source of this mod please

Just checked the Streamliner manual online which states: [font=Arial][size=2] [i][size=4]• The AMBER “PEAK” LED indicates that the power amp is near its maximum power. Under high output conditions it is normal for this LED to light with the strongest pulses of the signal. Driving hard beyond this point will cause the amplifier to gradually begin to clip which may become audible. If using a very mid focused bass tone and while driving the amp hard, it may be possible to hear some distortion before the PEAK LED is lit. This is normal and is a result of the harmonics generated by the preamp tubes during the overdrive process being more audible since the ear is more sensitive to upper midrange frequencies.[/size][/i][/size][/font] [font=Arial][size=2] [size=4]Also the manual states:[/size][/size][/font] [font=Arial][size=2] [i][size=4][b]SPEAKER OUTPUTS – [/b]The Streamliner™ 900 provides two Neutrik Speak-On™ connectors (wired 1+/1-). The speaker jacks are paralleled. [u][b]The minimum speaker load is 4 ohms[/b][/u]. Do not ground either the “+” or the “-” outputs. Because this is a high voltage, high current output, ¼” output jacks are not provided in order to comply with international safety standards. It is never an issue for the Streamliner™ to be used without a speaker load connected.[/size][/i][/size][/font]

I'm sure I read somewhere that the GB 'peak' light is more of a signal indicator and that its ok flashing and only a problem if it stays on continuously - then again I might have dreamt that Good point about the two cabs mind. I'm sure the Streamliner was a minimum 4 ohm load.

[quote name='Billy Apple' timestamp='1399672764' post='2446668'] Are people who bought the 69'er not a bit miffed that it's been side-lined so soon? [/quote] Isn't that always the downside to going 'boutique'? Either faster product replacement cycles or worse still the company disappears leaving you with something that depreciates quicker than a quick thing on a quick day.

Hi and welcome to the forum. Collective wisdom would suggest adding a second PF210 and stacking them on end. Aside from the deeply technical reasons for having four speakers in a single column (others are far better qualified than me to explain the positive benefits of this arrangement) the main benefit will be getting a speaker up nearer your ear, which on a loud stage can make a hell of a difference.

Fired this tasty little combination up tonight for the first time - oof what can I say [IMG]http://img.photobucket.com/albums/v208/JPJ/IMG_1032_zps516d85c9.jpg[/IMG]

Don't forget to put some wadding on the inside of the back as well

[quote name='nickademus' timestamp='1399665725' post='2446569'] So why are these modified 10" guitar speakers Alex is using not neo? Cost? [/quote] Oh no, another can of worms opened - neo vs ceramic [pulls up comfy chair and sits down]

I used spray carpet adhesive to good effect, along with contact adhesive. You can use PVA to glue the 'field' which will give you time to adjust the tolex but I'd always recommend contact adhesive for the edges unless you've lots of clamps, batons and patience!

Its probably fair to say that we are a conservative lot and have for years been fed speaker cabinets in 4 and 8 ohm nominal impedance variants by the big company marketing depts. so are less tolerant of other numbers. I for one remember the 3x10 5.33ohm cabs of not so long ago, and the fact that these have more or less disappeared suggests that our love of 4 & 8 is pretty deeply engrained. I currently run a (nominally 4ohm) 6x10 as my main cab and I love it. It does exactly what I want it to do and it 'sounds' like I want it to 'sound' but here's the rub, the manufacturer is no longer in business. Getting spare drivers therefore is a no-no so if (when) a driver or two give up the ghost, I'll have no alternative but to recone the thing using proprietary 4 or 8 ohm drivers for a nominal (you guessed it) 5.33ohm load. I continue to be intrigued by the Barefaced story, but not intrigued enough yet to part with any cash (sorry Alex). I felt I really understood the 'science' behind the original three-way cabs and having heard my bass through top end three-way PA gear, I could see the rationale. However, now the story has changed to 'actually two-way is just as good' which concerns me and makes me wonder whether the latest recruit at Barefaced HQ isn't an accountant. I get what Alex is trying to do, and I've heard a number of his cabs 'in real life' situations and as a result, I think I understand what this lack of colouration means. I'm still not sure that this transparency is what I would like behind me, but one-day I know I'm going to have to part with the cash and find out for myself, but the latest Gen3 stuff does make me wonder whether he isn't heading a little more 'main stream'.

Its a total subjective subject Personally, I like tens because they 'appear' to give me the sound I like. That said, loudspeaker technology has advanced so much in the last 10 years that I'd probably like 12's and 15's if I tried them. I was reading the specs on one FaitalPro 12" LF driver the other day that had a resonant frequency of 45hz and an Xmax of 12.45mm - thats an awful lot of air moving trouser flapping capability in a lightweight neo driver package

I've just bought a QSC PLX1602 poweramp from Mike. Great deal, very friendly communications (despite my souk style bartering) and fast turnaround. Amp arrived in great condition in the original packaging along with the power cable and the manual. Its obvious Mike takes care of his gear, deal with him with confidence.

GK have their own version of bi-amping. Using their RB series cabs with their heads has a separate amp for the tweeter (50w) and then the main amp for the drivers. To achieve this they use 4 pole speakons where the +1/-1 terminals carry the main amp to the drivers and the +2/-2 terminals carry the tweeter amp to the tweeter. From what was posted earlier, according to the manual in bridge mode, you get a full range signal on +1/-1 so a conventional 2 pole speakon lead will take the full bridge mono output to another manufacturers cab such as the SWR.

Is there no manufacturers out there doing a mono amp with reasonable output rather than having to have a stereo amp in bridge mode?

Then it should be ok with a standard +1/-1 speakon lead. BTW the goliath Snr is one hell of a cab. I'm in the process of replacing two goliath 4x10's with mine (one 4x10 already gone to a new home)
