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.

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.

[quote name='alexclaber' post='504874' date='Jun 3 2009, 05:23 PM']If I may say so I thought my advice was rather good! Alex[/quote] We don’t really know what the problem is here, do we? All Sam says is that he can’t get the right tone in a practice situation with his band. I’m not really sure what that means but you assume that his cabinet isn't powerful enough – even you don’t even know what kind of a band he’s playing in. What if the cabinet is mistuned? You just advised him to build another mistuned cabinet and patted yourself on the back for doing so.

The advice being dished out in this section of the forum has always been a bit iffy, but is now becoming increasingly pointless because nobody bothers to read the questions properly. You need to understand what the problem is before you can give sensible advice.

[quote name='fatgoogle' post='503385' date='Jun 1 2009, 10:48 PM']but ive been struggling to get a useabl;e tone at band practise with, it, its grand at home.[/quote] Could you be more specific about the problem?

[quote name='mathewsanchez' post='504011' date='Jun 2 2009, 05:19 PM']I'll take either or both if dannybuoy or stevie don't take them. Just PM if that's the case, but no worries if they're gone.[/quote] I'm not after them - I was just commenting on the generosity of the offer.

[quote name='warwickhunt' post='503294' date='Jun 1 2009, 08:50 PM']Cover the postage and they are yours.[/quote] That's a nice thought.

[quote name='benwhiteuk' post='463054' date='Apr 15 2009, 03:07 PM']Not heard of these before and I can't find much info on it. How good is it, how much do they cost, and where might I be able to get one from? [/quote] The logo reminds me of the Amptown amps they used to make in Hamburg. According to the German bass chatters list, they are not very well known in Germany either.

[quote name='lewisS' post='502494' date='May 31 2009, 07:24 PM']hey im in need of a band in dorchester(dorset) area for metal/scremo genre[/quote] What about these guys?

Interesting. Thanks, Foxen.

[quote name='rmorris' post='502220' date='May 31 2009, 12:38 PM']But as long as you use cable with a decent amount of copper the power loss on the cable will be insignificant.[/quote] The resistance of 30m of your recommended 6-amp cable is nearly 1 ohm.

[quote name='Mr. Foxen' post='502194' date='May 31 2009, 12:18 PM']I did mine to learn how all the different parts sounded.[/quote] How would you sum up what you learned from doing this?

[quote name='joshua' post='501510' date='May 30 2009, 11:34 AM']thanks for the replies, the longest of the cables is 10m, this one: [url="http://www.disco-world.co.uk/cables/10m-speakon-to-speakon-speaker-cable/prod_63.html"]http://www.disco-world.co.uk/cables/10m-sp...le/prod_63.html[/url] unfortunately it doesnt have much other info such as the gauge[/quote] In which case, you should definitely shorten it. 10m is much too long.

[quote name='joshua' post='501166' date='May 29 2009, 06:42 PM']Im just wondering if the cable length has any effect on power? Basically, I have a head, then a VERY long speakon cable connecting a cab, then a much shorter speakon cable connecting another cab to the previous cab. Am I losing a lot of wattage by having a long speakon cable? And am I doing any damage by having two very different lengths?[/quote] Yes, you are. How much depends on how long the cable is and how thick it is. You are not doing any harm, but why not cut the cable to the length you need and reconnect the Speakon? You just need some wire strippers and the appropriate Allen key. No soldering needed.
