[quote name='jhk' post='245625' date='Jul 22 2008, 07:33 PM']I`ve tried your suggestion and hey presto,at least I know the horn works. So the problem is within the circuit board or components.I`ve run the tester over the components and the one marked T.I 15 OhF 5% MEA 200VDC is not letting any signal or circuit go through! is that the crossover? can i get diagrams or specific components from peavey?[/quote] Would that be 15 uF? Sound like a film cap. Can you measure capacitance with your meter? To confirm that it's not working, bypass it with some wire - keep the volume low, obviously. It would be very unusual for a 200V filmcap to go in an HF circuit. It's a bit difficult to troubleshoot blind at this distance but I'll try to help (although I'm only here now and then). If the crossover uses an L-pad (like a volume control), chances are that's what's gone.

[quote name='Bill Fitzmaurice' post='244865' date='Jul 21 2008, 10:03 PM']The SRX715 and SRX725 have used the 2256 neo magnet woofer since 2004.[/quote] I don’t know why you’ve even come back to me on this one: the fact that you have ignored and snipped my mention of the Cinema Series shows you know you are wrong. The SRX series is shown using the 2226H on the current JBL Pro website. [url="http://www.jblpro.com/pages/mi/srx/srx.htm"]http://www.jblpro.com/pages/mi/srx/srx.htm[/url] They also seem to be on sale at retail outlets. If my information is wrong, blame JBL. Not that it matters. It only takes a single exception to disprove your blanket statement that the 2226 isn't used in current JBL prosound systems. However, for the sake of completeness, the 2008 JBL catalogue shows that the 2226H is used in the following systems at least. There may well be more, but my time for this kind of nonsense is limited. Variable Line Array Series PD5125 VLA301 VLA601 VLA901 Precision Directivity Series PD5125 Cinema Series 3631 5672 5674 3678 4675 - and not in the catalogue but listed on the website: Dance Club Series Dance 3 Permanent Install Products CST51DQ So, I humbly submit that the 2226H is indeed current and is indeed used in JBL’s current prosound offerings - although I’m not sure what proving it does. After all, a 4-year old Mercedes S-Class is always going to be a better quality car than a brand new Ford focus.

[quote name='stingrayfan' post='244459' date='Jul 21 2008, 02:46 PM']It's the sound you'll be left with when you've forgotten the price. And if you like the way it sounded - go for it. I'd be tempted to take it out of its sleeve and put it in a rack anyway.[/quote] I don't wish to hijack this thread, but which of the cheaper, less powerful Trace Elliot heads (including the old ones) would you recommend?

[quote name='Bill Fitzmaurice' post='244699' date='Jul 21 2008, 07:03 PM']Still in production, but hardly current. The telling point is that JBL no longer uses it in their current pro-sound cabinet offerings. JBLs top of the line drivers have been neo for nigh on a decade, but they are not sold as separate components.[/quote] JBL uses the 2226 in its current SR-X series and in its Cinema loudspeakers - both pro-sound cabinet offerings. Why don't you check your assertions before serving them up to us as facts?

[quote name='Bill Fitzmaurice' post='244699' date='Jul 21 2008, 07:03 PM']On-axis plots may give that indication, but off-axis response is what matters. At 45 degrees off-axis the 2226 drops like a stone above 1kHz, and is down (and out as it were) by 16dB at 1.5kHz.[/quote] The off-axis performance of a 2226H is a function of its diameter. It is no better or worse (and its response doesn’t drop off any faster) than any other 15 inch driver. Just a few messages ago you were praising the superior high frequency extension of the Eminence 3015. Now you are telling us that the JBL’s midrange extension is irrelevant because its response – like every other 15-inch speaker - drops off above 1kHz. If you serve up two completely contradictory statements like this, why should anyone believe either?

[quote name='alexclaber' post='241879' date='Jul 17 2008, 04:34 PM']The main problem I've had with most non-Eminence woofer designs is that they are either designed as mid-bass or midrange drivers for PA and thus Xmax and Qts are too low or Fs too high so they can't handle or create the bottom or they're designed as PA subwoofers and the problem is reversed with a resultant loss of sensitivity and midrange output. If you can direct me to a better 15" for bass guitar, or even a good 10" or 12", I'd be very interested to see.[/quote] You're right: it’s difficult to design a long excursion woofer that performs well in the midrange, but you’re wrong if you think Eminence has a solution in the Kappalite. Why do you think they have two versions? The JBL 2226H, on the other hand, pulls off the trick of having long excursion, high power handling and good quality extended midrange.

[quote name='chris_b' post='240261' date='Jul 15 2008, 06:10 PM']Why are you replacing the speakers? Do they just need reconing?[/quote] Just what I was thinking. They should be able to send you a recone kit. Are they under warranty?

[quote name='billynoband' post='241877' date='Jul 17 2008, 04:33 PM']If you put numbers in Winsd you get something big enough to hang your wifes clothes in. Anyone else noticed that. [/quote] Also, - winsd doesn't model floor reinforcement nor (as far as I can remember) the cabinet response step. The curve you get in winsd is actually nothing like real life.

[/quote] You have to know what you want your system to do. If you let winsd dictate cabinet size, it will suggest standard alignments, which aren't necessarily what you want.

[quote name='Bill Fitzmaurice' post='241793' date='Jul 17 2008, 02:53 PM']+1. As good as the 2226 was when introduced it's day is long over. Consider that even JBL has not used them in their high end products for years. As a standalone driver the 3015 has twice the useable bandwidth, while as a pure woofer the 3015LF at half the weight has twice the displacement limited power input capability. If all you desire is a simple cabinet the horse's mouth can be found at [url="http://www.eminence.com/resources/cabinets.asp"]http://www.eminence.com/resources/cabinets.asp[/url][/quote] I checked, and the 2226H is actually a current model. So it’s day isn’t over at all - especially as there are a number of other manufacturers selling very close copies (Beyma, RCF, Usher and other less well known companies). Interestingly, Eminence tried to copy it at one point, and I tested that one, too - but it sounded goddam awful in the mid. The 3015 doesn’t have twice the useable bandwidth – look at the JBL spec sheet - nor twice the displacement limited power input capacity for that matter. It is lighter though (doh!), so you got that right. The 3015 may be the bee's knees, especially at its dollar price, but that doesn't detract from the fact that the JBL is a 2226H is still a superb driver.

[quote name='alexclaber' post='241763' date='Jul 17 2008, 02:01 PM']You do indeed need to update your information. I have modelled countless 10", 12" and 15" drivers from all those names and the Kappalites consistently come out extremely well regardless of price. The 2226H looks more comparable to a 3015LF (though has less Xmax and weighs a lot more) in that the treble extension is very limited and thus really needs a midrange speaker unless you only play dub/reggae. Alex[/quote] I think you'll find there's a bit more to it than putting the numbers in winsd, Alex.

[quote name='RichardH' post='241705' date='Jul 17 2008, 01:05 PM']Recommendations?[/quote] My hands-on experience is a bit out of date, I'm afraid. My favourite bass driver when I was in the business was the JBL 2226H. I don't think they make them any more but you can pick one up on eBay for seventy or eighty pounds. For tone, thump and output, it takes some beating and I don't think there is much to compare with it even today. There's also the JBL K140, but they are a bit rare. Companies like RCF, Fane, B&C and 18Sound are all making good quality drivers, but they cost from around £150 up. The problem with Eminence is that they are built down to a price to suit the OEM market, which means you are likely to end up with something that sounds very ordinary indeed. I know that's not going to go down well on this forum, and I haven't tried their latest speakers, but I tested the entire range at one time, and I just could not get a quality sound from them. I'm not saying 'don't use them', but I'm saying - be aware. I wouldn't mind betting that a JBL 2226H in your cabinet would outperform any comparable bass cabinet currently on the market. Could be worth a punt.

[quote name='RichardH' post='241594' date='Jul 17 2008, 11:07 AM']No, the Eminence range have suitable drivers. I used a Gamma 15 in mine - based on Eminence's recommended volume in a vented cab it suited OK, and it certainly sounds deadly. I used a Kappa 12 for the 12" unit.[/quote] That's a really nice cabinet you built. I doubt if you can buy anything comparable nowadays - which is one of the benefits of self-build. Please don't take this the wrong way, but it really deserves a better driver.

A big thank-you to escholl for the bridge for my Yammy. Much appreciated.

[quote name='lowhand_mike' post='241578' date='Jul 17 2008, 10:52 AM']does it HAVE to be made with EV's own drivers? if not what can you use?[/quote] No, it's a straightforward 90-litre reflex cabinet and should work well with most 15" bass guitar speakers designed for reflex. You should avoid the higher tunings and use the 45Hz tuning irrespective of the speaker you use. I'm sure someone on here will advise on the suitability of any specific driver, but it would have to be an unusual driver not to work. Stevie

I'd gladly take these off your hands. The bridge looks a lot better than the one that's on my Yamaha and I'd be interested in trying the stacked pickup, as the bridge pickup of my Yammy is noisy. Can't pick up, unfortunately, but I could cover the cost of post and packing, if that wouldn't be too much trouble.

[quote name='radansey' post='225368' date='Jun 23 2008, 08:59 PM']OK, similar question to other posts on here. My Peavey TNT115s quotes 150W in 4 ohms, however getting hold of 4 ohm replacement speakers is proving difficult at present so therefore I am thinking of getting an 8 ohm. Apart from a decrease in overall gain, what are the advantages/disadvantages in doing this? Assuming that halving the impedance does not mean a halving in available gain, can assume a max gain in the region of 100W into 8 ohms? I also want to wire-in a connector to enable me to parallel-wire a second 8-ohm cabinet at a later date if required. Ross[/quote] Thank you for spelling impedance correctly.

[quote name='chris_b' post='223872' date='Jun 21 2008, 10:35 PM']Bass players on the Grease Soundtrack album are: Mike Porcaro, William David Hungate, Max Bennett, David Allen Ryan, Wm. J. Bodine, Dean Cortez and Harold Cowart. John Farrar wrote You're The One That I Want and Hopelessly Devoted To You. Toto was formed as a result of the musicians working together on the album.[/quote] You certainly pick up some useful information on here!

[quote name='gypsymoth' post='223709' date='Jun 21 2008, 05:49 PM']it is a brilliant song - there's a couple more in there too.[/quote] Hopelessly Devoted to You (which I think was also a Farrar song) was one of the first songs I learned on the bass (not that long ago). It's nice and easy to play, easy to read, and is so, so tasteful. Another goodie that I find really fun to play, although it's a bit cheesie, is My First, My last, My Everything, by Barry White.
