Speaker flapping?

[Rip Van Dan]

This is a very limited, entry level combo. At higher volume, if you are boosting the bass eq, what you are experiencing is what I would expect. IIRC, it's about 100 watts into the internal speaker and 180 watts with an extension cabinet.

Actually that's an Eden EC-15 and is one of the Eden combo's where they use a 4Ω speaker in it to get the maximum power from the amp as-is because it's only a 180-watt amp. If you plug in an extension cab, it disconnects the interior speaker. The only reasonable upgrade path to that is one of their 410 cabs or perhaps the 210 if you want the sound of 10's instead of 15's. It specifically targeted rehearsal spaces and small stages. That speaker should easily handle the power in the amp. I'd be interested to see what he finds.

That’s not what I saw from the limited documentation that I have seen, but of course the documentation could be riddled with errors too.

That said, G4M shows the speaker as 4 ohms, so who knows.

I'm positive about the 4Ω speaker and the cut-off of the internal speaker when you use the extension speaker jack because, in about 2017, I was looking for an Eden 112 combo for that small brewpub where we played almost every Friday, but Eden didn't offer an EC12 at the time. Disconnecting the internal speaker when using an extension speaker was, by the way, exactly the opposite of previous E-series and Nemesis combos.

I almost went with that EC15 but balked at the fact than an extension speaker would cut off the internal speaker and I really wanted a 112 anyhow. So I bought an EX112 cab and after using it the first night with my older Nemesis RS400 amp, ordered a second one. Then down the road a bit I got that low-powered Eden TN-226 (225-watts rms into 4Ω) class D amp to run it because 4.7-lbs. is a lot less than 15-lb. RS400. REALLY should have bought those in 8Ω but never expected to buy a second 112 and I could use my 410 everywhere else.

The EC15 (stands for E-series Combo, 15" speaker) uses the same speaker that is in the EX-115 cab. EX stands for E-series, eXtra speaker, and it is a 300-watt rms speaker. That's why I said that speaker will easily handle the 180-watts from the amp unless he's cranking the Bass EQ on it. That combo first came out in 2013 although the 115 speaker was used in the 2011/2012 catalog in the EM115. The EM stood for E-series Metromix. That Metromix series was designed for use of 2 inputs and has two headphone outs specifically to facilitate teacher/student type of use besides using as a normal bass amp. 2014 was the last time those Metromix amps were in the Eden catalog. The EC combos were still in the 2016 catalog, which was the last catalog that Eden published.

Evidently his problem with his sound was some loose fabric inside that was flapping against the port.

I know when the drummer leaves his sticks laying on the snare drum and I start noodling .. I can play the bass and the drums at the same time... Just sayin.

@agedhorse Ok tonight I'll try to boost the bass and see what is happening. I'll pull the speaker out of the enclosure tonight to investigate further.
@MrBassman22 Bofff.. i want to have the deep bass from a bass speaker really.
@jimmydean, i'll investigate loose components tonight..
@HardNHeavy I really think it's the speaker, i'll retest tonight anyway with more bass boost and more volume.
@DuluthDank @lug I'll try it in another room to rule out room vibration.

Thanks for the tips.

Using a high pass filter to filter out the non-audible bass/rumble leaves more room for audible bass en allows for a deeper sound.
