AlanP2008 Posted January 4, 2010 Share Posted January 4, 2010 Hi, a newbie here... I've been looking for suitable 10" speakers to upgrade a budget 2x10 cabinet (Mag 210). Part of the issue is that a 4ohm cab would be much more useful to me than the current 8 ohms, so as to extract more from my SS amp... I wouldn't mind getting a couple of Neos, so I've been looking at Eminence Deltalite II 2510 data (plus standard Deltas), also at Celestion, and a bunch of other candidates stocked at Blue Aran... ... I've come to the view that, as someone with an electronic engineering background, and in the distant past an audio engineering background, if I were designing a bass cabinet today, I wouldn't even consider 10" drivers -- 12" would be the minimum, for all sorts of reasons (resonant frequency and useful frequency range being just two of them...) And yet there are so many 2x10 and 4x10 cabs out there.... Is this all just fad? (Although of course I do understand the attraction of smaller, lighter cabinets.) Are there any 10" drivers that are actually really suitable for bass guitar applications - or have I just not been lucky so far? (I play 4-string bass, so my requirements are not as low-down as many others....) Thanks in Advance Alan Quote Link to comment Share on other sites More sharing options...
Mr. Foxen Posted January 4, 2010 Share Posted January 4, 2010 Don't think going 4 ohm would make enough difference to be worth the change. The Sica drivers are kind of lame though, so upgrading for moe power handling and sensitivity is more viable. Is it a sealed or ported cab? Makes a fairly huge difference in driver choice. I just stuck a spare Delta 12 in my EB combo and it is a definite improvement. Also, check the Barefaced forum section, lots of info relevant there.

You'd also find that the 2x10 is, all things considered, the most versatile configuration when the drivers are vertically aligned (and most are not) while the 4x10 is the most intrinsically flawed. Where tens are concerned my preference lies with the Eminence Basslite S2010 and Deltalite II 2510. Quote Link to comment Share on other sites More sharing options...

For the delta lites, the 10's are clearly less useful in terms of low-end frequencies (for bass), the 12's will be loudest (and true, the 15's don't look any better than the 12's, but are a bit less sensitive): 2510: Resonance 53Hz, Usable Frequency Range 60Hz-4kHz, Sensitivity 97.3 2512: Resonance 42Hz, Usable Frequency Range 54Hz-3.7kHz, Sensitivity 99.9 2515: Resonance 42Hz, Usable Frequency Range 54Hz-3.7kHz, Sensitivity 99.2 Basslite S2010: Resonance 46Hz, Usable Frequency Range 54Hz-4kHz, Sensitivity 96.2 There doesn't *appear* to be anything stand-out there (or against 10's in other ranges/brands either)... But I do appreciate your responses to my question. I wondered if there was any other brand around that I hadn't spotted that might be more appropriate - but maybe there isn't... I appreciate what you say about vertical alignment though - the old principle of the "column speakers" - it is odd how things come into and go out of fashion. Re the topic of my post, it looks as if a 2x12 would probably give most "bang per buck" (a better compromise) comparing power, frequency response, size, weight, sensitivity and cost, than 2x10, 4x10, or 1x15 = but they don't seem very popular at all...

(and it's ported....) Does anyone know what speaker is used in Ashdown's ABM series - they seem to boast 102dB sensitivity, versus the 98dB of the MAG series - that's double the volume right there...

A 4 ohm small cab can generally only be used on its own as either you have to pair it with another 4 ohm and find an amp that runs down to 2 ohm, wire them in parrellel giving you an 8 ohm load or have a mismatch and it wont be so easy to sell on later on Also by the time you have bought a couple of decent tens you might as well buy a better cab, or build one of Bills, Quote Link to comment Share on other sites More sharing options...

mikhay77 Posted January 4, 2010 Share Posted January 4, 2010 After trying these new style neo speakers,I have gone back to old skool .I had a trace 2x10 with horn,uprated to 400w neo style,yes more responsive but didnt seem to handle the full range,tried it along side my 1048h (also 300w)and no comparison,yes I know the cab is larger but there is no substitute for movement of air,and the neos did tend to break up when pushing the lows,also thats why I got rid of the markbass,but thats just my personal opinion.

JTUK Posted January 4, 2010 Share Posted January 4, 2010 My upgrade to Delta 2510 over PAS chassis' was a result, IMV... the cab is down to 4 ohms..which is incidental, but the power is upto 500watts and the weight save is good. Maybe this was a happy accident but I am pleased I went that route although I had to replace the speakers anyway.. otherwise I would not have bothered. Soundwise, not much in it, but the power increase and the weight save works ok.. I don't use the cab as a standalone for any powerful gigs either.. I would consider 2 2x10's as a rig but currently add a 15" underneath. I think a lot depends on the structure of the cab with Neo's in it.

That can only be determined using all the driver T/S parameters with speaker enclosure modeling software like WinISD Alpha Pro for the region of pistonic function, roughly up to 200 Hz, and the SPL charts from the manufacturer driver data sheets for above 200 Hz. And then there's the matter of being able to interpret the results. BTW, if one only had the above data as predictors the differences between the four drivers listed would be, for all practical purposes, inaudible.

BTW, if one only had the above data as predictors the differences between the four drivers listed would be, for all practical purposes, inaudible.[/quote] Well I got hold of WinISD Pro and spent some time getting to grips with it. From the volume and the porting, the cab seems to be tuned to around 41Hz (which makes some sense I guess, given the likely resonance of te speakers). The speakers in the Mag 210 at the moment are Chinese made Eminence, without any id of the model number. Putting the models of the Emi Alpha in there (assuming the speaker is one of their cheaper designs...) it doesn't look too bad, but distinctly light on the bass end. There seems to be little point putting very high powered pairs of 10s in there, as speakers like the 2510 and S2010 (which looks a bit better in terms of response, but I haven't found anywhere in the UK that stocks them) end up displacement limited, and the bottom end still isn't that great. Putting just a single 10 in there improves the bass response immensely, but makes the displacement problem much much worse - you can't get more than about 120W out of it at 41Hz, or else the speaker in poling like crazy (Xmax is 4mm or so, but Xlim, where damage can occur is up around 8mm). I tried a lot of different things - no amount of tuning would make much diffference to the basic problems - poor bass response, and or displacement limited at quite low power. The best thing I found, was in trying a single Eminence Delta 12 LFA - a single 12", and it seems much better than a Deltalite 2512... It's Resonance is pretty low at 51Hz, and also being a single speaker in the cab gives an excellent bass response, but mainly, it has a massive Xlim at 13.5mm, which allows a lot of power to be used even with bottom strings. Ok, Xmax isn't so high, but it is good at 4.8mm. I know there is likely to be increased distortion if this is exceeded, but at least it won't be trashing the voicecoil... It isn't a brilliantly sensitive speaker at 94.6dB and I suppose that's the worst part - but at least you can get some power into it without trashing it... It's rated at 500W continuous. The main thing though, is that I got a convincing response curve (F3 at 42Hz), with the ability to get it powered up well... ... does this sound reasonable, or have I missed something (I haven't missed the point that this is all simulated...)?

(The D12LF now seems to be the D12LFA - the specs are different from the D12LF, although I'm sure it is just an improved version. - equally, WinISD Pro seems to only have models for the older types, DeltaLite rather then DeltaLite II, for example - I guess you have to update the specs yourself... that's what I did.) Re Xmax/Xlim: My understanding is that if you exceed Xmax, distortion will exceed some arbitrary value that the manufacturer uses to establish Xmax, whereas exceeding Xlim is likely to result in damage. If a bassist is rocking out, and it's all getting a bit noisy - he's unlikely to be concerned by a bit of increased distortion on peaks as he exceeds Xmax... (and anyway, some people like that kind of speaker compression). But he *will* be concerned if the voice coil starts hitting the stops, and/or he destroys his speakers! ... maybe I've got that all wrong?

AlanP2008 Posted January 10, 2010 Author Share Posted January 10, 2010 Quick take on the 3012HO is good. Similarly low(ish) Fs at 51.5, very good Xmax and Xlim at 6.2mm (!) and 12.5mm, and excellent sensitivity at 100.5dB (that's worth amplifier money right there!)... Haven't found a supplier in the Uk though (Boo!) I'll try it out in WinISD (got to build the model first...) Thanks Alan Quote Link to comment Share on other sites More sharing options...

Some manufacturers still use the old coil depth versus plate thickness method, and that is arbitrary and obsolete. Xmax tells you the maximum safe power level that may be applied, and it's what you consider if you have a limiter that allows restricting power amp output, though that's more of a PA scenario. Exceed xlim and the driver is damaged, irreparably so, so it's not something you want to even vaguely flirt with. [quote]I had a trace 2x10 with horn,uprated to 400w neo style,yes more responsive but didnt seem to handle the full range,[/quote]All that indicates is that you used the wrong ones. You can't just drop any driver into a cab willy nilly and expect a good result. A very fair amount of research is necessary, as this thread reveals.
