YC-810 Big B replacement speakers or mod

RickenTalker · #1 06-22-2011, 12:46 PM

Yesterday I played my bass rig out of ether an 70 or 80s ampeg 810s svt cab. It made my rig sound amazing, so amazing that I feel like I need to reanalyze my current cab. I'm currently rocking a late 60s Traynor 810s cab. It's currently loaded with Eminence LEGEND BP102 ( which are rated a lot bigger (200watts) then what was originally used in the cab, if that has any affect). So is there a particular speaker or way of getting that svt cab sound out of this cabinet?

The 102's roll off at about 2.5 k if I remember correctly. The Eminence Legend 810 looks like a better choice to me.

The eminence B810 is the replacement speaker for ampeg style sealed 810's. If your 810 has a port, plug it and wire all 8 speakers in parallel. (32ohm drivers).

Compare the graph to the BP102 while your there. Much better mid/low treble response.

my 810s have no ports. The only thing that I dont like about those replacement ampeg speakers is that they are rated at 32ohms which sorta makes it hard to mix and match if necessary. Are there any other speakers out there that would be better suited for this?

will33 · #5 06-22-2011, 01:33 PM

32 ohms = 4ohm 810....or an 8ohm 410.

What's to mix -n- match?

RickenTalker · #6 06-22-2011, 01:51 PM

oh ok, I see. SO even though it says 32 ohms on the ampeg speakers it wouldn't make a difference if I were to take one of the speakers out and put a speaker rated at 8ohms in instead...
Am I correct?

I have two Traynor YC-810 cabinets. One is stock with the original eight 10" Marsland 25 watt 8 OHM speakers in it. The speakers have never been reconed or replaced in it. This cabinet is currently for sale.

The other YC-810 also has the original eight 10" Marsland 25 watt 8 OHM speakers in it, but they were all reconed a year ago which brings the cabinet back to its original specs and sounds great.

I considered replacing the originals with higher power Emminence 10", but decided that I wanted to keep the cabinet 100% original, so I chose to recone instead.

Replacing just one would throw everything off yes. I'm talking about using 4 or 8 - 32 ohm drivers all in parallel.

If it's full of bp102's now and you don't want to buy 8 new drivers another option might be to highpass some guitar speakers in the top 2 or 4 positions and keep your bp102's handling the lows in the bottom half of the cab. If yours doesn't have all the separate chambers inside like the svt you'd have to build the guitar drivers into their own little sealed box within the box.

RickenTalker · #9 06-22-2011, 04:36 PM

Thats another question I wanted to ask. How sealed are the speakers on an SVT compared to the Traynor810s? I got a picture here of what my cabinet looks like when opened up DSC_0555 | Flickr - Photo Sharing!] This cab is a bit newer then mine, but it's still relatively if not exactly the same

will33 · #10 06-22-2011, 04:49 PM

Provided you've got a good gasket on the back panel, that's a sealed box. The drivers aren't sealed off from each other because of the shelf wraps around the middle ones.

That doesn't make any difference if you're using all the same drivers. It does mean it would take a little creative construction (meaning setting your saw at an angle) to get some guitar drivers sealed off from the woofers.

It also needs needs some lining on the top, bottom and side walls and some thicker type stuffing on the back panel.

Honestly, that cab will never sound like the Ampeg, regardless of what drivers you load in it. You’re better off selling the Traynor as is, and getting an Ampeg. CL is chocked full of them. You’ll be better off financially as well.

will33 · #12 06-22-2011, 05:16 PM

If you were to do 2 guitar drivers + 6 bp102's I would make the middle 2 guitar drivers so they'd be lined up vertically as they'd have more mid/high content coming from them.

If you were to do 4 + 4 I don't know that it'd matter much as it'd be a mishmash no matter how you did it. (short of cutting a whole new front board with everything lined up right in which case you'd be better off building a whole new cab and leaving this old Traynor unmolested).....or just buy a used ampeg.

@ punkrocko--

The ampeg 810 ain't rocket science....far from it. If they'd have crossfired the 2 columns of 4 and put "pluggable" ports in it it would be a well designed cab.

And yes, I've played more than enough of them to know what they're all about.

I agree with you.

I just think at the end of the day, he’s going to put a lot of time and $$$ into this and be disappointed at the results.

Fridge cabs are cheap and plentiful, and that’s what he wants. There’s someone out there that would appreciate the Traynor as is, without the guts all hacked out.

will33 · #14 06-22-2011, 06:01 PM

I may end up agreeing with you. Not to bash ampeg too much...the older ones that used guitar drivers or "not so good spec'd bass speakers" were the cats pajamas. I haven't spent time with the newest ones but I can look at charts, etc. and know if they're using the B810 or something close it'll be a helluva improvement over what they been doing, got a feeling I might like it again but there was a period late 90's - 2000's where I heard and played waaaayy too many fridges that were dull, thuddy, like they had a blanket over them. Really turned me off, shouldn't have taken anywhere near that long to figure out there was a problem and fix it.

The very newest line looks promising on paper, but the proof's in the pudding and I haven't had my pudding yet.

My sentiments exactly!

RickenTalker · #16 06-22-2011, 10:18 PM

That Traynor stack is magical. Well ya'll have convinced me to sell my Traynor. I'm ether going to try and get an old 70-80s svt 810 like I played out of or get something completely different.

1. That it were mine (at least the cabs)

2. That the cabs were stacked three high.

I don't think I'll post this pic any more, even I'm getting tired of looking at it.

awesome traynor rig ! im impressed. i have to disagree with will33 and punkroco. if you angle the speakers inward (like a sunn cab) you would lose cabinet volume big time. then you lose the low end it has. add a port, and it wont sound as tight as a sealed cabinet. it will sound like all other cabinets. i doubt people will be trying to find early markbass cabinets in 40 years because of the sound... yet they will still be seeking ampeg 8x10's. (just my theory)

I know I'm a bit late to chime in on this thread which I have read through with great interest. I've been playing bass for a long time and when it comes to bass rigs I know what I would like to hear but have yet to play through anything that I feel compelled to go out and buy.

I've been doing a lot research on 10" speakers and cabs.

One of the primary issues RickenTalker is up against is comparing two different speakers, apples vs oranges.

A stock SVT cabinet should have an impedance of 4 ohms which is done by connecting eight 32-ohm speakers in parallel. The BP102's in the Traynor cabinet are 8 ohm speakers and can be wired to make a 4 ohm load (parallel/series) , 1 ohm load (parallel) or 16 ohm load (series/parallel). If the Traynor turned out be a 16 ohm load then it will not be nearly as loud as the SVT cabinet.

Also the SVT speakers have a more extended frequency range and have a slightly louder sensitivity than the BP102's. The SVT speakers are fairly linear out to 3kHz or 4kHz while BP102 drops off the map at around 2kHz. This all means that the SVT will sound brighter and louder than the BP102's even if the impedance of both cabs is the same. And it appears that the SVT cabinet has a bigger internal volume than the Traynor. This will definitely make the cab sound different than the Traynor.

Eminence replacement for the SVT speaker is the Legend B810. While these are not exactly the same as the OEM SVT speakers, they are much closer than the BP102's.

If the Traynor cabs are to be upgraded to get closer to the SVT than I would look at speakers with a linear frequency response at least to 3kHz and a sensitivity rating of 92.7dB or better.

More Bass!
