Celestion TF1020 replacement speakers $108 for 4 (shipped)

[baalroo]

here, under "scratch, dent, and overstock

Avatar is doing what they are calling a "factory buyout sale" on 8 and 16 ohm Celestion TF1020s (10" replacement speakers).

1 for $41 shipped
2 for $68 shipped
4 for $108 shipped

That's $34 each for 2 or $27 each for 4. I didn't search too hard, but best price I found was about $50 PLUS shipping online.

would these work if i replaced my stock gallian-kruger 10" speakers? i have a GK BACKLINE 300 WATT head pushing it. would they sound better than my stock GK speakers?

you could go to musicians friend and tell them about this deal and they will beat it! i am guessing they would sell you 4 for $97.20. try it out ,i know they will beat that price.

[baalroo]

That's actually pretty much what I'm doing, I'm replacing the 10s in a GK backline 210 cab. Just keep in mind that the 1020s are "mid-rangy"... but then so are GK backlines.

I just ordered 1 for my blown 10 inch in my Ampeg SVT-1510 cab... super stoked to get that thing back up and running!!!
Spent:
Ampeg SVT-1510 = $110
Celestion TF1020 = $41
Total = $151.00 for a kickin' 15, 10 American Made Ampeg Cab!!!

I have a 2x10 cab that has the drivers pharting when pushed. These Celestions are on helluva deal to replace them! Hope they still have them available Monday.

[baalroo]

So I ordered these last Thursday, got them on Tuesday, swapped out the old speakers and practiced on Wednesday, and gigged with them Friday. They are DEFINITELY punchy, with noticeably more mids than the stock drivers I replaced in my junky GK backline cab. I went from 8 to 4 ohm so it's hard to compare exactly, but I'm quite happy with the results... especially considering the cost.

[bassplayer8953]

I ordered a pair today, should be delivered by the end of the week. Hopefully they make my old cabinet like new.

...strange to order something long-distance & not use the internet, paypal, or the other things we've learned to take for granted...

...continued: Received the speakers Friday, put'em in the cab during the weekend. Cab sounds great: punchy & tight. The 1 x 15 cab pushes the air & the low end, so things are working great. Thanks Avatar: good speakers, great price, fast shipping!

anyone know how these would work in an older eden d210t box?

[clickr]

I have a blown speaker in my laney 810. I wanna replace the top 4 with these. The cab is 4ohm but I dont know whether to get 8ohm or 16ohm speakers. Id check the ones in it, but my multimeter is busted. Any ideas?

[froghat]

A 4-ohm 810 cab has either 8 32-ohm speakers all wired in parallel or 8 8-ohm speakers wired in series-parallel.

The only way to know for sure is to open up the cab (or call the manufacturer). You don't need a multimeter. Just look to see if there is a single path between the + terminals on all the speakers. If so, you need 32-ohm speakers. If the wiring is more complex (i.e. wires running from + terminal on one speaker to - terminal on another), then you need 8-ohm speakers.

Unless the top and bottom halves of the cabinet are isolated from each other, it might be best to bite the bullet and buy 8 new speakers.

[froghat]

BTW, the Xmax is only 2mm on these speakers and their resonant frequency is 78Hz. (For reference, the Xmax on an Eminence Delta is 3.5mm and on an Eminence Legend BP102 it's 6mm. Their fs values are 66Hz and 35Hz respectively.)

That is, these are low-mid drivers. You really want to check their specs against your cabinet's volume and porting. It might be best just to buy a replacement driver from Laney.

[clickr]

The top and bottom are separated inside and it's all sealed. Hoping the bottom 4 will hold the low end and the new ones will add some mid punch. For the price I could resell them at no loss if it ends up not working out. I appreciate the info, 8ohm it is!!

FWIW:I put one of these in an SWR Workingman 10 enclosure that had been gutted. Works quite well as a 1x10 for quiet-ish practice. I think I'll also be able to use it for my duo with PA support.dcr

[MuthaFunk]

I'm going to give these a shot in my somewhat tired Goliath Jr. II

There doesn't seem to be any real good alternative other than buying new SWR replacements on ebay and IMO the cab is not worth dumping that cost into. New drivers don't seem to last all that long anyways. Recones aren't very good either the last time I tried.

For the cost of a pair of them, I'll see how they sound on top of my very deep sounding and efficient Big Ben Cab.

Can't wait to hear it.

[hdbassman2000]

just dropped a pair into the old eden 210t and was pleasantly surprised (or relieved) that they sound so damn good! they are a bit mid friendly, but not as much as some would think. very nice charecter and definition and at $68 shipped to your door, you just can't go wrong. the stamped frames cut back on the LBS as well. all in all, i think its a pretty good testimony to david's cab designs as much as the speakers themselves.

I needed a new speaker to replace the breaking down G10-30 AVT in my Marshall AVT20 practice amp which I use for bass practice. 110 dB at 20 watts (full distortion) measured by sound level meter, indicating 97 dB speaker efficiency if you do the math.

I tried a stock Eminence B102 that I keep on hand, but the output was way too low for my taste, but the bandwidth was very good. At 92 dB efficiency, it just wasn't loud enough for my taste, reducing apparent relative output to just above 5 watts. This is a recommended replacement per an Eminence replacement list I looked up.

At 97 dB efficiency, the Celestion TF1020 MIGHT seem like a good replacement, but it has some serious drawbacks if you read the specs. It has an excursion max of 2mm, which is WAY below the Xmax of an Eminence Beta 10A at 3.1mm, which is also rated almost 97 dB efficiency. The TF1020 power handling is 150W at 60-3000 Hz bandwidth. The Beta 10A is rated 250W at 51-3800 Hz bandwidth. Both power ratings are FAR more than I need, but the free air resonance is the real concern, 79 Hz for the TF1020 and 53 HZ for the Beta 10A.

The TF1020 is more like a good speaker for detuned guitar than for a bass guitar speaker. The peak in the presence range on the Beta 10A will give better off axis response and eliminate the need for a tweeter.

The Alpha 10A is lighter than the TF1020 and has the same power rating, slightly better Xmax, better bandwidth, can be had all the time for $50 and a free air resonance of 50 HZ. Being a standard Eminence, recone kits should be available if you ever need one.

The TF1020 is best used in a high pass configuration, just as the factory specs suggest. Would be good configured with a low pass cab, but I wouldn't want it for bass in a stand alone combo if you punch it with high power at low frequencies. There must be a reason you can pick them up so cheap, as they full retail at $105, with a MAP of $70. However, if you have lots of bass gear and can use it as a high pass cab, then it looks like a killer deal. Just that I need a full range bass driver, so I ordered the Beta 10A at $70 delivered.

With neither deep bass, nor extended highs, the TF1020 would seem to be a very "midrangey" driver if that is what a person needed. The very limited Xmax for a bass driver seems to really indicate this. The early bass rolloff would help tame standing waves and wolf notes in a small venue. It ain't gonna work in a small combo amp if you want to do a wide range of styles for practice. It depends on the second harmonic to make you think the fundamental is there.

I like the 44-4000 Hz and very flat frequency response of the B102, but it's so power hungry that it doesn't work well in a low power combo unless you like low volume practice levels. On a website pertaining to single-driver audiophile speaker construction, the B102 is a recommended speaker for a low cost project, and they had developed a filter network that flattened and extended the frequency response even further. Many of the Lowther speakers sell for between $500-$1000 per speaker, are very efficient but can't take much power or put out much bass like the B102. Jimi Hendrix personally used Lowther loudspeakers for his critical music listening, and they are very revealing of detail buried in complex mixes, which his music was all about.

Thus, you can turn a B102 into sort of a Lowther with much better bass response, and you can add that audiophile filter to your B102 if you want to smooth it out and extend it some more. The top end of the TF1020 is too ragged for any kind of frequency extension by shelving down the midrange to B102 efficiency levels, unless you like a ragged top end.

Since I am an audiophile and a new bass convert, I will be experimenting on smoothing out the response of my bass amp. I'm used to the tight and extended bass of a Vandersteen, but since it's a patented bass alignment (invented by the former chief engineer of McIntosh Labs, Mile Nestorovic), you have to build it yourself and figure out the filter network for the passive radiator. I have to send in my Vandersteen woofers for reconing this summer, so I will get a look at the filter network and how it's hooked up when I tear into the speakers. My AVT20 only has room for a standard flat passive radiator on the back panel, the Vandersteen alignment uses a hi-Q woofer with it's voice coil attached to a frequency spreading network and no attachment to the incoming signal or crossover filter. Driven by pressure waves, but spread filtered electrically. An answer to the deficient low frequency output of high efficiency bass drivers..........maybe.

To get the classic Marshall bass amp sound, you would of course run the AVT20/AVT50/AVT100 into a cab with something like a Celestion G12H(55), because the difference between an early Marshall bass amp and guitar amp was the speakers in the cab, which were simply lower resonance models of the higher resonance G12H speakers. I want to pretend I have a Marshall head with a more modern cab. I have a G12H laying around if I want to go there.

Dave raised the price to $154

[MLC_BassPlayer]

I bought four of these (16. Ohms) but traded the 410 cabinet before I had a chance to really test them, so they are sitting around taking up space. Probably a really good deal for cash or trade....
