Spoombung Posted March 12, 2009 Posted March 12, 2009 (edited) Hi I've got one of these - a Roland cube 30: It's a great little amp and I'm particularly fond of the 10" speaker. It's described as [i]"10-inch coaxial 2-way speaker design"[/i]. I looks like a normal speaker with a slightly elevated centre piece. I know nothing about speakers but it has a broad frequency range. My question is does anybody make a more powerful version of this speaker (say 100watt) in a smallish cabinet that I could use with my old HH amp? Or is there a company that sells this type of speaker? A Google search hasn't revealed much... Edited March 12, 2009 by Spoombung Quote
Mr. Foxen Posted March 12, 2009 Posted March 12, 2009 I think its 2 speakers, a smaller one pokes out the middle of the big one. Would figure there is a crossover so its just like a woofer tweeter arrangement. If the Cube100 has the same deal, then there is your answer. Quote

Soulfinger Posted March 13, 2009 Posted March 13, 2009 Eden made cabinets featuring speakers with coaxial tweeters. I think they came in 1x10" and 1x12". May be worth a shot on the ´bay... Quote

Alex[/quote] Yes, it looks a bit like that. I used to have a cab with a speaker in like that and it sounded great - all the frequencies plus some high end. Can't remember what I did with it. I reckon that's what I want Quote

alexclaber Posted March 13, 2009 Posted March 13, 2009 Before everyone gets too excited there are quite a few different sorts of coaxial speaker. Basically one family is those coax designs which use a separate woofer and tweeter with an electronic crossver. This tweeter can be mounted in front front of the woofer, centred within the woofer with a horn in front of the woofer, or within the woofer with the woofer cone used as a waveguide. This kind of speaker sounds very much like a conventional 2-way speaker but with better phase coherence due to the concentric sources. The other family of concentric speakers are the whizzer cone speakers, where a separate smaller cone is attached directly to the voice coil whilst the main cone is attached with a flexible joint which acts as a mechanical lowpass filter on the woofer whilst allowing the whizzer to produce more highs due to the lower moving mass. The response of these speakers tends to be somewhat peaky due to the break-up modes of the whizzer but they're a nice way of getting more highs from a basic speaker. Their big limitation with bass guitar is that no-one makes a whizzer cone speaker with good Xmax so although sensitivity tends to be high their excursion limited power handling and thus max LF SPL is very low.

I assume you mean it won't be bassy enough - although I remember the 'wizzer' cone speaker was a bassy enough for me. Is [i]wizzer[/i] a make or description?[/quote] Xmax is how far a cone can more forwards or backwards with <10% distortion. Combined with cone area it is the limiting factor in how loud you can get the lows from a speaker. However a speaker with low Xmax can have excellent bottom and sound very bassy - you just won't be able to turn it up far before the distortion starts increasing and the sound gets less and less bassy. Whizzer is the description for the additional smaller cone attached to the main cone. They've been used in hi-fi since the '40s I believe, maybe earlier and the Lowther driver is the most famous example and is still popular with single driver aficianados: Lowther drivers tend to be used in enormous rear-loaded horn cabs, which increase the pressure behind the cone so that you can get more bottom from the minimal Xmax (if you double the pressure of the air you're moving then the cone only need move half as far to get the same SPL.)

Prosebass Posted March 13, 2009 Posted March 13, 2009 Hi Kev what will you be using the speaker for (and don't say bass guitar) is it for practice low volume or will you need to gig with it ? Quote
