[quote name='whynot' timestamp='1387745480' post='2315199'] Absolutely loving the Tecamp Black Jag. Used last night as backline with a Schroeder 1212L. My trousers were flapping a little. This amp covers everything I want in tone. Below is with matching M212 but not had a chance to gig both together yet. [/quote] agh you got it in the end! good stuff!

[quote name='Bill Fitzmaurice' timestamp='1387828778' post='2316276'] If you have at least a 5 band EQ then you have enough control for a horn loaded cab. It might not be for you with less than that. I use a Superfly now, before it I had a Hartke 3500, both have all the adjustability I need. PA is a lot more fussy, that's where a 31 band with auto RTA is almost indespensible. [/quote] cheers for the reply Bill I've only got 4 bands, and not swept.

wahhaay! enjoy it!

thanks for help Phil and Balcro!

[quote name='Bill Fitzmaurice' timestamp='1387823076' post='2316160'] Read this: [url="http://www.avsforum.com/t/1353217/speaker-shootout"]http://www.avsforum....peaker-shootout[/url] Or the first page, anyway. The DR200 and DR250 are my designs, fully horn loaded, not just the tweeters. True, EQ is an absolute necessity, but that's true of all speakers, let alone high sensitivity pro-sound horns, because there are no rooms with flat response. Not that I recommend pro-sound PA cabs for home stereo/theater, this guys system is overkill to the nth degree. But there's no such thing as horn 'honk' with a well designed horn, be it a tweeter or a subwoofer. There are a lot of poorly done horns, though, so the notion is understandable. [/quote] Bill you actually hit on a question I've been wondering about... So compare an SPL chart from a bass reflex cab, say your very own Simplexx (the 12 bass/key cab 2512 woofer and apt80 tweeter) line to a horn loaded speaker, I'll use your Jack 12 with the same speaker as an example... now this is me the simpleton speaking here.... with a bass amp into the Simplexx I could plug it in and have a reasonable idea on how it will work and what the eq will do.... with the jack... how do you in your exp. eq the horn... just I'm not sure that my bass amp would be flexible enough to eq in the right places, I guess ideally you use a power amp with inbuilt DSP and just plug a preamp into that... I understand that practically the horn design is better and more efficient etc... but how practically do you make it work? Or in the real world once you stick the cab in a room does it make no difference? Edit: it wouldn't let me link to the charts on your forum.... simplexx here .... http://billfitzmaurice.info/forum/viewtopic.php?f=12&t=20963 jack here ... http://billfitzmaurice.info/forum/viewtopic.php?f=12&t=8778

As a wee update... the clarity of the Warwick Hellborg preamp handles the richness of the ACG preamp...

[quote name='Dad3353' timestamp='1387736965' post='2315080'] Less than ideal choice of screw colour there, imo... Other than that, I'd love to try 'em out. Are they heavy ('cos I'm old and decrepit... )..? [/quote] right... you... you're going to be visited by 3 ghosts this christmas! The Ghost of Barefaced are good/bad, the Ghost of Leo got it right first time and the ghost of why buy a fodera when you can buy a squier. And it will last all christmas- on repeat, ad infintium

[quote name='molan' timestamp='1387732365' post='2314991'] A few weeks back we sold a cab to a customer by making him face away whilst we plugged in a variety of different cabs whilst he kept playing. He walked away with a Bag End 1x10". Not at all what he was looking for when he came in We sometimes give people a selection of basses to play and refuse to tell them how much they cost. Did that recently with a batch of Fender J's and the customer bought a Mexican with upgraded pickups ahead of a stock USA model. It simply sounded better and played just as well. Blind testing is definitely a good idea when it's practical [/quote] blind testing is brilliant- I went through a phase where I decided I "had" to have a jazz bass - so rather than go on here or a shop and buy the "best" I could find I went and played loads and loads. Realised that there is an slight and indirect correlation between price and quality - but you can find some gems. The most fun to play was an old japanese cimar that cost me £40 (I bought that one), the all round best, the Valenti that Richardd is trying to sell at the moment (why did I sell it I don't know) the most dull and dead sounding was a sadowsky. (though not all sadowskys I tried were dull and dead) With Fender stuff themselves I loved the american vintage reissue series, and highway one - but couldn't find a nice USA one in-between that. And with nice chinese squiers seeming to be a better buy than mexican fender. The moral of it was blind testing is good - so often we are blinded by the price tag or looks. It also made me realise that a fair few bass designs are fairly generic and the difference between a top of the top range and bottom isn't that massive. And that some basses will be engineered in a way that they can do things that no other bass can. If that thing is what you want then it's worth buying- whether it's a £10k Ritter (for Molan), a £100 set of pickups or something lovely and made of Wenge (the 1985 Thumb bass I got last week). We do ourselves no favours when we look at the price rather than the engineering.... anyway.... I would say though for cabs... how do you do blind testing in the shop? it's different to a live occasion... I'ld love to give it a try though!

[quote name='Balcro' timestamp='1387723746' post='2314892'] Hi Luke, Nice to see someone else who also finds WinIsd results occasionally surprising. I presume that the SICA units were in there from new. I tried a different tack and re-ran WinIsd using the "super boom-box" option under the Choose Alignment option. That produced more conventional results as far as the response curve was concerned. WinIsd left to its own devices came up with a 41 litre box tuned to 54 Hz. If you tweak that up to 65 litres and a tuning of 68Hz the graph looks smoother with very slight rise near 85Hz (a square vent 6cm x 24cm). Probably average for a bass guitar cab - just around the frequency of Low E or F. Check out Maximum Power & Cone excursion! These things sure ain't hi-fi! Balcro [/quote] Ok, so copied what you did with box volume and tuning and got the same response with the peak at 85Hz I then Increased the box volume to 100l which is what I estimate mine is (measuring the inside minus handles and struts) and then added my port dimensions.... it's a rectangle with a semi circle on each end, so converting the area of the circle into a rectangle we end up with a square port 30.5x9.5 with a depth of the wood at 1.5 cm. Which gives me a tuning freq of 80.76Hz, the graph then gives me a not very flat at all peak of 6db at 88Hz going down to -3 at 67Hz - so that's what I can hear!!!! I had a look at max power and cone excursion - but I don't really know what I should be expecting to see to compare it... wiggly lines but don't know what they are supposed to look like -max power: steep steep curve up off the graph at about 75Hz, dip down at about 100hz and then up again

like these too? (first person to mention screw colour gets to be scrooge this christmas btw)

Have you looked on the Matamp website? they had a pdf up of demo stuff in the sale not so long ago. and also they aren't far from you. Also when you get it and realise you need a more vintage looking cab to match them, I'm sure I can help you out getting rid of those Ead cabs of yours

so you can buy another streamer?

[quote name='Ou7shined' timestamp='1387662631' post='2314430'] Most versatile​ circuit? Schack. [/quote] does he have space to fit a pingray pickup setup in there too?

[quote name='Balcro' timestamp='1387666025' post='2314453'] The SICA speaker is on their website. A Neo magnet version rated at 250w. Fundamental resonance "Fs" is quoted as 54Hz. The horn is probably also by SICA as the letters N and TW appear under the heading "Studio Monitor tweeter". Tecamp also refer to an NTW1 horn. I had a play with the main unit in WinIsd and it has an exaggerated upward twist in the lower end frequency response. Tuning is probably in the 60's (Hz). I've no idea about that small quantity of foam. Balcro. [/quote] exaggerated as in it shoots up before it drops down on the graph? hits zero at about 60 and -3 at about 40? if that's the case maybe I wasn't being so stupid with winISD as I thought I was

is that the photo that you've now taken down?

aubergine's aren't green. But sorry everyone - we ate ours

getting hooked and spending all your free time hunched over with a soldering iron...

agh but could your daughter be convinced with amazing aubergine based recipes? It's green with white tips, I guess it's supposed to look like it's been snowed on or something.

Inspired by some of the threads recently and my wanting to understand a bit more about speaker cabs armed with a screw driver I attacked my cab tecamp m210 today! Initially I planned to look at WinISD and plug the numbers in there but after opening it and starting I realised that the whole thing was a bit beyond my ability at the moment... But I found out.... My cab weighs about 18kg give or take... I knew this already - what I didn't realise is that about 14% or 2.5kg of that weight is made up from the front grill - which seems mental to me! it's more metal than holes if that makes sense. The box is quite well braced with spars going back to front around the edge panels and two more in the middle. Taking off the handles and the bracing I would say it has a volume of around 100l The drivers are Sica Z006900 and the horn has no stamping or anything on it. The vent is a rectangle with semi circle ends cut in the front baffle, area about 289cm[sup]2[/sup] and 15mm deep. I have no idea what tuning this gives the cab as I don't have a working amp at present I can feed into the cab. the cab doesn't have very much damping material- there is some egg crate foam damping material, but only on the back wall, not on the sides. What effect would that amount have? I've seen other cabs ranging from speakers loaded in a ball of fluff right up to empty with no damping material. so while it may be of no interest to you if you've read this far... but it was quite interesting looking inside. I'm intreated what adding more damping material would have to it, and may try and work out a way of making a lighter grill..

just a thought, looking at the price of Wals.... could you go have a try of ACG's Uber spec line and see how they compare... if they do then you could possibly get one [i]and [/i]an overwater... of course it wouldn't "be" a Wal
