(or handling large amounts of freight) they can offer the similar shipping costs of the larger retails stores that DO ship internationally. I think you JOIN up with them - for somethin' like $8 US All this is AFAIK.[/quote] Third party shippers are a method to get the full kit including Eminence from Leland. It's noted here: [url="http://billfitzmaurice.info/forum/viewtopic.php?f=14&t=9905&sid=8078ac451297146fb5af0c47f534da8a"]http://billfitzmaurice.info/forum/viewtopi...5af0c47f534da8a[/url]

[quote name='4 Strings' post='1010352' date='Nov 3 2010, 04:26 AM']I wonder if this is the same here, smaller boxes can mimic with ever increasing accuracy but there's no substitute for volume. Even if small cones can be made to work a lot of them will be needed.[/quote]The performance triad is cabinet size, sensitivity and low frequency extension. Any one or two may be compensated for by alteration of the remaining. If one desires a small cab that goes low the odd man out is sensitivity, which may be compensated for by higher power input. But that requires a driver capable of making use of said power, and an amp capable of delivering it. Both of those can add considerable cost. The least expensive solution comes with a larger driver(s) and larger cab, but then you need the means to carry it to the gig. What remains a constant is that there's no such thing as a free lunch.

[quote name='Brave Sir Robin' post='1010231' date='Nov 2 2010, 08:12 PM']Just entertaining a thought, but from a purely mechanical point of view, a bigger cone will certainly make a bigger displacement easier, and will move a lot of air by itself relatively easily. Unless your small cone design has some funky engineering allowing it to move back and forth a lot without shredding itself to pieces. Hence my point regarding how easier and cheaper it is to produce a large speaker than an array of small, high quality, higly durable 10'' speakers. Or then again, I could be wrong.[/quote] The cost per cc. of displacement does go down as the size of the cone goes up. But as already noted larger cones are generally accompanied with less high frequency extension, and are always accompanied with narrowed dispersion, so there is a point of diminishing returns. IMO there's no advantage to going larger than a fifteen, and I wouldn't even use a direct radiating fifteen on its own without a midrange driver, due to the midrange beaming issues with a fifteen.

[quote name='Brave Sir Robin' post='1010201' date='Nov 2 2010, 07:37 PM']I've always understood it is much easier (and cheaper) to get powerful ultra low frequencies with a large speaker, at the expense of poor higher frequency response. Not really an expert, but I'd love to hear an expert opinion about the qualities of large speakers vs small speakers for reproducing low frequencies at high volumes.[/quote] Driver size in and of itself is moot. Where low frequency output capability is concerned what matters is driver displacement, sensitivity and frequency response. Those are related to driver size, but only anecdotally.

[quote name='woodster909' post='1007056' date='Oct 31 2010, 06:06 AM']no delivery service straight off their website, but UPS will do a pick up and deliver freight service. I'd image others too like FedEx[/quote]The Jack flat packs aren't terribly large or heavy, so shipping shouldn't be all that bad. But the packs are normally not sold without drivers and other parts, and SH can't ship Eminence overseas. You'd have to contact Leland at SH directly to get the packs without the Eminence part of it.

Clean them with a damp rag. So long as you don't soak the cones they won't be bothered.

[quote name='RickIronWitch' post='1002509' date='Oct 27 2010, 09:30 AM']500watts together? Cheers[/quote]Neither. Assuming your amp has a volume control you can use any power rated speaker with it. If the speakers distort turn it down.

[quote name='LukeFRC' post='1001415' date='Oct 26 2010, 12:29 PM']new! sure looks like a cutting edge design to me![/quote] If you like that you'll love this: And would be willing to pay 200,000 quid for a reissue!

[quote name='bigevilman' post='1000216' date='Oct 25 2010, 12:14 PM']I want to put a new speaker in there as 250 watts rating ain't nearly enough![/quote] The thermal rating is moot. Output is limited by displacement (T/S spec Vd).

[quote name='GRAHAM SG1' post='990506' date='Oct 16 2010, 02:12 PM']Hello guys, I have not been on here for a while so thought I would say hello . I have got a GK MB210 and am really pleased with it, I am still waiting for the MBE210 cab to arrive on UK shores, have been told it will be here end October so fingers crossed, is anyone else on here waiting ?[/quote] A couple of issues you should be aware of: [url="http://www.talkbass.com/forum/showthread.php?t=688140"]http://www.talkbass.com/forum/showthread.php?t=688140[/url] [url="http://www.talkbass.com/forum/showthread.php?t=693727"]http://www.talkbass.com/forum/showthread.php?t=693727[/url]

[quote name='xgsjx' post='987586' date='Oct 13 2010, 07:12 PM']I'd go with Mr Hunt's suggestion. 2 2x10s vertically offer a better dispersion & easier to carry than any of the other options.[/quote]+1. Of all commercially available options this is the most versatile and probably the best sounding.

[quote name='mikebass78' post='977614' date='Oct 4 2010, 03:35 PM']I've also looked at eminence and legend speakers but keep getting turned off by the listed frequency response, can anyone recommend a roughly 300w 8ohm speaker that can match the celestion at the low low end??[/quote] Have you modeled the Celestion in question in the cab to see its actual response? Listed frequency response means little.

[quote name='justis' post='974971' date='Oct 2 2010, 08:28 AM']can i take a line out from my bass head (a horrible behringer piece of sh*t but it works) or maybe even the effect out and then put it into a guitar combo to give me the ability to have distortion without losing the bass[/quote]Chris Squire's been doing just that since 1968. It's a popular technique.

[quote name='Phil Starr' post='974909' date='Oct 2 2010, 07:38 AM']The advantage of the bass hump in an instrument speaker is obvious; it will make the cab sound bassier and if you combine this with the midrange hump of the beta it will sound quite lively. A bit like switching the loudness control on a cheap hifi and I guess this is why BFM suggested it.[/quote] A high Q driver is the last option I'd take if I had plenty of power, but the OP doesn't. He may find a lower Q driver works perfectly well with only 100 watts, but then again, he may not, and I doubt he's inclined to embark on a driver testing regimen. Many users of older lower powered amps have replaced the original drivers with Betas and Deltas and found they work quite well. No surprise that, as the Betas and Deltas have specs very similar to vintage drivers, but with higher excursion.

[quote name='Beer of the Bass' post='973104' date='Sep 30 2010, 02:45 PM']Is the Delta also worth looking at, or does the bigger Xmax of the Beta make it a better option?[/quote]The Delta response is smoother, though it has only half the displacement limited power of the Beta. But it still probably has twice the displacement limited power of that Celestion.

[quote name='Protium' post='973160' date='Sep 30 2010, 03:33 PM']Unless you stand it vertically [/quote] Of course, but I doubt you'll find that recommendation in the Trace documentation. Can't do it, you know, as it will look odd.

[quote name='Count Bassy' post='973056' date='Sep 30 2010, 01:54 PM']But is it good enough? The OPs problem of movement between the cone and the dome suggests that the original glue might not be up to it.[/quote] Cyanoacrylic is the industry standard. It won't fail, but the humans/machinery that apply it sometimes do.

[quote name='MythSte' post='972982' date='Sep 30 2010, 12:46 PM']and where would something like a Trace Elliot Bright Box come into the mix? Sorry, I quite enjoy picking your brains! ^_^[/quote] Totally flawed, as drivers should never be horizontally arrayed. The intent is to widen the coverage, the result is to narrow it.

[quote name='MythSte' post='972945' date='Sep 30 2010, 12:18 PM']From a bassists point of view Bill, Could it be said that tweeters could be "enough" to add sparkle to slap pieces if your happy with the overall tone of say a single 15?[/quote]IMO no, because if you haven't heard a 15/6 or 15/8 you don't know what you're missing. As 15/6 and 15/8, and for that matter 12/6 and 12/8, are still primarily the domain of DIY and custom builds few players are aware of how well they work. Most who do have them also tweeter equipped find that they prefer the tone with the tweeters turned off; those who don't have tweeters for the most part don't miss them.

[quote name='BassBen' post='972747' date='Sep 30 2010, 09:35 AM']So what are the pros and cons to using the MarkBass tweeter box?[/quote]Tweeters and fifteens result in a response hole over an octave wide between where the woofer stops and the tweeter begins, and that's on-axis. Off-axis the gap is closer to two octaves, and it's those two octaves that are most critical to tone. Fully two thirds of the tweeter frequency range is above where it offers any benefit with bass. For that matter tweeters and tens or twelves aren't all that good a match either, unless said tweeters operate down to at least 2kHz, and few do. That doesn't say that tweeters bring nothing to the table, but mid drivers bring much more. The primary reason why tweeters are offered instead of midrange drivers is cost.

[quote name='BassBen' post='972658' date='Sep 30 2010, 08:37 AM']Hi guys, Quick question really. I run a markbass little iii with barefaced compact. If I wanted to add a little harsh highend to cut through the mix can I connect a markbass tweeter box to the speaker jack on the amp? Would I damage anything by doing it? Cheers,[/quote] I'd use a midrange driver, just as Alex does in the Big One.

[quote name='stevie' post='972650' date='Sep 30 2010, 08:28 AM']Yes, that Beta is great for recreating the vintage sound of your grandad's radiogram. [/quote] Or a Portaflex. Delta 15s are the preferred replacement drivers in the lower powered models, where the 2.7mm xmax is of no concern.

[quote name='Mr. Foxen' post='972094' date='Sep 29 2010, 04:20 PM']Eminence Kappalite 3015, spensive, but happy in that box, and sensitive. If you are only running 100w don't need to worry much about the port either, more power and it wants to be bigger/two of them.[/quote] This is one case where the 3015 might not be right. Low power amps tend to rely on high Qts drivers that give a midbass response bump to get adequate volume, at the expense of low end. The Eminence Beta 15 is one example.

[quote name='BottomEndian' post='970689' date='Sep 28 2010, 09:10 AM']Not very. It's all been done before. [/quote] Ad nauseum, in fact. Comparing cabs based on the driver size is as accurate a method as comparing automobiles based on tire size. The one thing that can be said of the insistence that driver size is crucial is that the insistor has no idea how speakers actually work.

[quote name='wateroftyne' post='970611' date='Sep 28 2010, 08:09 AM']Cobblers. I know - I've played one.[/quote]+1. The only characteristic that's derived purely from driver size is dispersion. Period. Any other response/tone differences are from a dozen odd driver specs, specs which can be identical on tens, twelves and fifteens. Where dispersion is concerned that is as much a product of the driver configuration as driver size. Two tens side by side have the same dispersion as a twenty-one, so whatever advantage they might have in the mids is squandered in so doing. So, while the individual drivers in a 4x10 cab might have wider dispersion than a fifteen, the 1x15 will have wider dispersion than the 4x10. [quote]Is a Vintage 2x15"..? if so, expect the roll off around 3khz max[/quote]In terms of what really matters, off-axis response, 1.2kHz is more like it. Even a ten isn't much good above 2kHz off-axis. And if you place two tens side by side? Read the paragraph above.
