Disappointed with Ampeg PF-115HE.

I recently purchased the PF-500 head and absolutely love it. The tone is outstanding. It is, in my opinion, easily the best 500 watt class D head on the market for the price.

I've been running it through a Peavey TVX-412 as my main gig rig. I wanted something more portable. Recently, I decided to purchase the matching PF-115HE (1x15) cabinet to go with it, since they are designed for one another. The package showed up today and I unboxed it, hooked it up, and started jamming.

Unfortunately, the experience was unsatisfactory. The head is great, but it seems like Ampeg kind of cut corners on the cab. The tone is lacking, as is the low-end. Also, the driver seemed to have very limited excursion and began to distort earlier than I had anticipated.:hmm:

Now I know you can't expect a $300 1x15 cabinet to compare to the volume, power handling, or low end of a 412, so that was not even a basis for comparison.

For a more realistic comparison, I A/B'ed it against my Acoustic B200 1x15 200 watt combo and came to the following conclusions:

Where the Ampeg wins: High frequencies. The tweeter in the PF-115HE is far better than in the B200. I had the Ampeg's tweeter set at the middle position. The highs were clear and pronounced. The tweeter produced no "sizzle" or "hum". Impressive, but for me, a tweeter is the least important feature of a bass cabinet.

Where the Acoustic was superior: Overall volume, mid-range presence, and low-end capabilities before driver distortion. I don't have a decibel meter or anything like that, but based on my most honest estimations, I would conclude that the combo could get about about 25% louder than the Ampeg. The tone was also better, and had a punchier, "growlier" personality (which is ironic because, when ran through the Peavey cab, the Ampeg tone is far superior to the Acoustic tone - I actually felt like the PF-115HE detracted from the outstanding tone of the PF-500!)

I tried to be as neutral with this A/B testing as possible. Both amps were set flat, the gain at noon, and I used the same bass for each amp and tried to the best of my ability to play with an equal amount of attack. The bass is a Schecter Raiden 4, passive, and all volume and tone controls were full on.

I know "volume" capabilities shouldn't be the deciding factor on a rig. For me, and I assume most of us, the most important feature of bass guitar equipment is tone. Unfortunately, (and I don't know if it's just cheaply made, not tuned to my taste, or what) the PF-115HE does not do its head justice. Volume is important, however. I can keep up with a full band while jamming on the Acoustic B200. I do not feel that the PF-115HE could have done this. Also, I expected the mid-range to be more pronounced. The cabinet just sounds "thin" and frail, to my ears.

So, unfortunately, I am shipping back the PF-115HE. I will certainly be keeping the PF-500, as it is easily one of the best sounding heads I have ever owned. The cabinet, sadly, fell short.
 
wow, kinda surprised a bit by that, not to many disappointments from ampeg. thats also taking into consideration that everyone will have different opinions. thanks for sharing the story though. im currently without a rig, so yer doin better than me! lol

Interesting.

I found exactly the same thing but I've had very limited time with the PF cabs. The shop was litterally just closed and they let me come in and crank it up for a few minutes. I was initially unimpressed - it just seemed to get into fart territory really quickly. I always just put this down to my not having enough time to tweak properly.
 
A couple points to consider:
First, you have to break in speakers, so they will come into their own after a few hours of playing, and
Second, "flat" isn't flat. Every amp has a baked in flavor, and if you don't compensate for that, then you really aren't getting an apples to apples comparison.
 
I felt the same way about the Pf-cabs. they couldnt handle much power at all. I parted ways with the cab and the head (pf500) and just bought a svt7pro and never looked back.

Would have been great if the cabs could handle the power better. One cool little portable rig, but oh well...
 
Understanding that it's tougher to do with a combo, it's still true that if you used different heads in your test, then you weren't testing only the speakers. Just keep that in mind in your judgement.

Or do what I would do and bust into that combo so you can test each head with each cab. Then you'll have a much more accurate picture.
 
I think you'd need 2 of the matching cabs 2/10 or 1/15 to find satisfaction at basic rock band volume. It's a small cab and they matched a speaker to it. I doubt it's a major speaker. A single mediocre 15 aint gonna do it/I have a Celestion Kappa LF 15 (in a GK goldline cab) that I've never been able to max it out, 700w no problem, and I doubt I could use it in those little Ampeg cabs. And to get some mid presence out of one 15, well the Ampeg LF500 seems voiced kind of "warm" (I got one) and if I'm driving a single 15 I crank the mid at 750 (mid channel 4). It still isn't as high-mid bright as my Hartke 350 or PV Tour amps. The LF500 into 2 cabs with lots of headroom for it's lows, is nice!
btw, unless you get a deal there aint Nothing at that price range. I was shocked to see something with an Ampeg logo on it, 500W for $299. I had to get a 2nd one, (1st was fatally flawed) before everything worked, but I'm happy about it. It's unique.
 
FWIW, I used a single EV TL 1x15" cab for years (with a 160w tube amp) as my only cab & had plenty of punch, volume etc... ymmv of course. But a good 1x15" CAN do the 'keep up' thing ime.


I've played in alot of rock bands over the years, and a 115 wouldn't cut it in nearly every one of them...

Also, other than the SVT-410HLF and SVT810e, I've found Ampeg cabs to be pretty mediocre... To each their own, though...

I think you're a looney.

:D

No, not really. Not every cab is for everyone, bro. I'm not THAT intense about Ampeg gear. But I have a couple of them. To me they sound like a cross between the two most popular B-15 cabs + a tweeter. But they do go quite a bit lower than cabs like the 810e and 410he, and that translates to needing more wattage to get the same output as a cab that doesn't go as low. Don't know what their fartout wattage is but I've had them cranking pretty good in my house (I could never get away with it on a gig, though!). For a cab you can pick up that cheap new, I think it's way better than most, but somewhat reduced output is the price for a low tuned cab.
 
Thanks Schpector. I appreciate the effort you put into the post. If it's any consolation, your loss is my gain: I think I'll skip the Portaflex 15.

I'm wondering how long you played it for (tekdiver500ft was talking about a few hours "break-in" time). Did you go that long?

Also, have you tried the Ampeg PN-115HLF and SVT-15E? I wonder how they would compare.
 
Try your PF 500's line out into the Acoustic's effects loop. If you like that sound, you might consider the Acoustic 1x15 cab as a smaller option. Or try a smaller Peavey cab.

I agree with the others about the "flat" setting test not being accurate. All amps color the sound to some degree--the "flat" tone setting isn't 12 o'clock positioning for all amps. That being said, the Acoustic amps are not given the respect that they deserve...probably due to the price point, as well as being the Guitar Center house brand. They are actually fairly reliable, have good tone, and are quite loud for their watts rating. I'm not all that surprised that the Acoustic amp seemed louder.
 
OP - It's entirely possible you happened to get a bum PF115. My first one lacked low end, and as you describe - distorted very early on. It didn't sound anything like what everyone else here on TB described theirs as sounding like. So I returned it - and got a second one. The replacement cab rocks! Even though it's not ported, it does put out a big deep low end. I recently picked up a second PF115 so I have a full PF500 stack, and just for schitzengrins - I'm going to make that second one one a rear ported, based off the B-100R. Call me nuts, but I'm going to try it.

If your able to return yours - I definitely would.
 
My first PF115HE was a bad one with what sounded like a voice coil rub. I didn't even mention it on TB until now because I just chalked it up to a random bad product. Breaking in the cabinets will really help with the low end. Personally, I rolled back the bass and boosted low mids (mids position 1) on the PF500 that I ran with the cabinets to make them sound a bit more like an 810E. That increased my perceived headroom but those cabs really do not lack in low end. I can vouch for them sounding like a louder B15 cab in many regards.

As far as power handling, I'd give them about 200w RMS before fartout. My short lived Mesa 400 could take one to it's limits putting out 180w RMS.
 
Had a similar experience with the Hartke HyDrive 115. Bought one to compliment the HX410 I have been so pleased with and was totally underwhelmed and disappointed. Even went so far as to get the 15" driver replaced under warranty. Still very unsatisfactory. Weak... Fharty lows.... Sold it never having gigged it. One 15 just don't hold a candle to 4x 10s!
