[quote name='Mr.T' post='524612' date='Jun 26 2009, 09:34 AM']Is it even a fair shoot-out?[/quote] It's only a fair shoot-out if you realize that the two types of cab offer different benefits. *All things being equal* (and I'm not referring to any brand here), a 15" will be louder and go lower. It's maximum output will also be greater. A 12" will be more compact and thus easier to transport. It will also have cleaner mids, a more extended high frequency response and a slightly better off axis response. Which is better will often depend on what you're looking for.

[quote name='alexclaber' post='524841' date='Jun 26 2009, 01:52 PM']I don't think anyone who's bought one has directly replaced a GS112 with a Compact. An Epifani UL112 owner who recently got a Barefaced Compact said this: "Having had the Compact a few days now and used it for two rehearsals yesterday I can confirm that it is superb smile.gif Just has so much more depth that my Epifani 1x12, much fuller across the whole range, punchier, lighter and a lot louder (I know it's not a fair comparison but even so). I've used the mid and treble eq on my Overwater in a way I never had before - the amp is set flat as usual but I can dial in mids and top end without it sounding all edgy and harsh. My new passive Fender Jazz sounds great through it too - so all in all extremely happy" Alex[/quote] The question wasn't about the Epifani UL112 but that's another nice plug for your product. Alex, how would you like it if other speaker manufacturers came on here and trashed your stuff?

That is such a brilliant album (apart from that awful Windmills track) with some very tasty bass playing.

[quote name='JTUK' post='511592' date='Jun 11 2009, 08:42 PM']Yes, nothing to put them in.....and I did indeed think about getting some 1x15 cabs made....never got round to it and I have that base ( no pun int' ) covered now... I'll dig them out and see what they sound like... and then put them on here for offers[/quote] That's a good idea. You haven't got any 2206s that you would like to dispose of (very cheaply) have you?

[quote name='alexclaber' post='514331' date='Jun 15 2009, 03:57 PM']Nothing will move more air for the money than the 3015LF.[/quote] This will - much more.

Just make sure you have money in your budget for some castors.

[quote name='JTUK' post='510068' date='Jun 10 2009, 12:23 PM']Original thought was to replace both with Eminence Deltalite II 2510's and get a weight save at the same time...but that would mean 2 chassis lying around...and I have enough of those already...albeit JBL 15's etc..[/quote] You've got JBL 15s just lying around. What are you - nuts?

[quote name='redstriper' post='505963' date='Jun 4 2009, 11:35 PM']Cheers Stevie (again) I'm not going anywhere...............[/quote] There was a thread on flats a few weeks ago when Geejay (Graham) generously offered up a used set of Ernie Ball flats and I got in there just before you. He said at the time that, if I decided not to keep them, you were next in line. Well, I tried them and liked them but I just couldn't get on with the gauge - they're 55 - 110s, the equivalent of telegraph wires. They put enormous pressure on the neck and slow my playing down. I like 55- 110 roundwounds, but these are something else. Anyway, I decided I should take the plunge and get myself some TIs. Unfortunately, when they arrived, the D was duff and I've put the Ernie Ball Chromes back on my bass while I await a replacement set. Funnily enough, this ties in with BottomEndian's post. I'll send you the set on as soon as I'm sorted and let you know when to expect them. If you try replacing the bottom three strings on your bass with the top three strings on this set, the tension and the sound won't be a million miles away from the sound of TIs. They are third-hand now, but I don't think they've been used much, as they still have a reasonable about of sparkle. Geejay asked me to cover the postage by giving a pound the next time I passed a charity box. So that's the deal for you too. And if they don't suit you, just pass them on to someone else on the list.

[quote name='redstriper' post='505952' date='Jun 4 2009, 11:22 PM']Do you want to sell me your old La Bellas cheap? I want to try some for size before I buy a new set. I'd also like to try some TIs if anyone's getting rid of an old set.[/quote] If you can hang on, I have a set of flats for you to try. More info tomorrow.

[quote name='fatgoogle' post='505779' date='Jun 4 2009, 08:04 PM']Ive been reading over that, reading over the Electro voice sheet and looking in the shed. Just to make sure i have plenty of 1/2" ply in the shed, but on the cab specs, it says to use 3/4" i reckon ill be grand just making sure. Yep and reading it blocking of the middle square port at the bottom will give me 1 1/2 octave extension in the low end i believe. It would easier for me to do the diagrams build with the square ports as my routers not great so the more round ports the more likely it is to go off.[/quote] I didn't realize you'd originally used 1/2" ply, and that's certainly another reason to go for a smaller cab. An unbraced 150-litre cab in 1/2" ply will resonate like mad at volume. Anyway, if you're going to use 1/2 ply, you must make sure you've got lots of bracing in there. Dig around on this forum: [url="http://www.talkbass.com/wiki/index.php/Fearful%E2%84%A2_12/6_%26_15/6#Crossover_designs"]http://www.talkbass.com/wiki/index.php/Fea...ossover_designs[/url] where there are lots of examples and pictures of some bass cabs made with 1/2" ply. The bracing you see in there is the minimum you should use. I'd also strongly recommend that you double up on the front baffle, i.e. glue two pieces together to give you one inch thickness. It won't be much heavier than a 1/2 inch baffle - because of the big hole in the middle - but it will be a lot stiffer. And post the results of your efforts in the DIY cabs section for us all to admire!

[quote name='fatgoogle' post='505706' date='Jun 4 2009, 06:51 PM']So i could make the same size box as in the diagram, and then just use two ports, sound ok, If you have time to work them out that would be great and i can decide which one to go with. Is the Electro voice one already tuned the way it is, so you make it and plonk the speaker in, or does some self calculations have to be done after building.[/quote] Your 100mm ports should be 180mm in that cab. If you want to design the cab specifically for 5-string, you should lengthen the ports - 245mm is optimum, but anything approaching that will help power handling on the low B. The cab will handle low B better than the one you have now. There are two tunings available on the EV cab. You need to use the lower of the two, which as far as I can figure out, involves blocking up part of the slot port. Have a look here: [url="http://basschat.co.uk/index.php?showtopic=380"]http://basschat.co.uk/index.php?showtopic=380[/url], where Below has made a very nice job of the EV cab.

It's a 90-litre cab, exactly the same volume as the small Trace 1153. The porting is a bit complicated because of the dual tuning frequency option. You could simplify it by using a full baffle with the two ports you already have. I can work out the port lengths if you like. If I were building it, I'd use two 4" ports at the bottom, move the driver a bit higher, put a 3" wide brace between the front and back panel just under the driver and a horizontal brace 3" deep two thirds up the cab on the back wall.

[quote name='chris_b' post='505275' date='Jun 4 2009, 09:27 AM']He was doing the 10 bass changes a set thing when I saw him with Bonnie Raitt at the Albert Hall. It sounded like he did it because he could, and the only difference I noticed was when he switched between fretted and fretless. Bonnie Raitt made a lot of changes too but I guess that was due to various open tunings.[/quote] If you didn't notice, it's unlikely any one did. Sounds a bit precious to me - but that's showbiz. I wonder what people would be saying if the drummer had changed his kit 10 times to perfectly suit each song.

[quote name='alexclaber' post='505368' date='Jun 4 2009, 11:44 AM']In my experience the shallower the cab, the easier it is to move! I'd much rather have a tall, wide-ish, shallow cab than an equal volume cube. Stick a handle on the side of the cab and you can carry it like a suitcase.[/quote] That's fair enough if you're talking about a lightweight cab with a neo driver, but a 30kg cab is not a comfortable one-handed lift for most people - certainly not for me!

[quote name='fatgoogle' post='505324' date='Jun 4 2009, 10:33 AM']But arent these things defined by the speaker, doesn't the speaker need a certain amount of space to move, so wouldnt building one based around a trace elliot cab, be sort of wrong. Im not sure though.[/quote] Most speakers suitable for use in reflex cabs work OK in a range of cab sizes, but there are limits at both ends of the scale. I only mentioned the Trace and Ashown (which are virtually identical in size) because they are quite a good shape, compact and easy to handle. A cab that is only 10 or 11 inches deep is going to be more awkward to move around. There is also a design on the web for a 15" cab from Electrovoice that some Basschatters have built, which would be suitable for the Fane. Try a search in the DIY section on here. I think it could be worth persevering with the Fane driver because it's a cut above what is fitted to most commercial cabs.

[quote name='neptunehealer' post='505152' date='Jun 3 2009, 10:52 PM']Yes they are the 1/4 pounders spb-3. Do they sound too thin in the mix though, i mean do they have much bottom end? Just have a suspicion that they are not versatile enough for me, but youtube and these internal laptop speakers don't show muich bottom end on many basses.[/quote] The quarter pounders swap some top end detail for added punch. They have plenty of bottom end. I'd echo what the others have said: you'll never know whether they are right for you until you fit them.

[quote name='fatgoogle' post='505144' date='Jun 3 2009, 10:39 PM']Sloe down slow down, im no physicist. im 16 just finished the easiest year ever, and a bit slow. Also how to i turn 100 litres into a box, eh stupid question i know, something they dont actually teach you. Also is this still a reflex cabinet. I suppose im saying please explain.[/quote] Your current cab is 154 litres internal volume. 70cm x 55cm 40cm (height x width x depth, I assume). Multiplying those three dimensions gives you 154,000ccs. Divide by 1000 to get litres, i.e. 154. If you want to end up with 100 litres internal volume you should allow an extra 5 litres to account for the volume taken up by the driver and bracing. Keeping the same baffle area of 70 x 55cm would mean reducing the cabinet depth to 27cm, which is a bit shallow compared with most bass cabs on the market. That's the theory anyway. 70 x 55 x 27cm = 103.95 litres. Yes, it's still a reflex cabinet, because you are using ports. I'd be tempted to build another cab based on the dimensions of the Trace Elliot 1153 or Ashdown Mag115, although you might understandably not be too keen to go down that route again.

The cab’s too big - and there is nothing worse that a speaker flapping around in an oversize cab - it just sounds all wrong. I can see why you complained about the tone. There is no need for a cabinet that size, as the extra volume gives you virtually nothing that you couldn't get from a more manageable 100-litre one. Look at the frequency response curves. The 150-litre cab is in red and the 100-litre cab is in orange. They’re tuned to slightly different frequencies, but you can see that all that extra volume makes virtually no difference. In practice, because the cone moves less in the smaller cab, the difference is nil. See the cone displacement comparison. You’ll get a tighter, cleaner sound if you put your driver in a 100 litre box. Use two 100mm ports, 150mm long. Perhaps you could reduce the depth of the cab and leave the rest as it is? You should end up with quite a capable speaker.

Seymour Duncan operate an exchange scheme, which the UK distributor should honour. Take it back and ask for an SPB-1 in its place. That is a more classic P-Bass sound and is probably what you are looking for.
