Carvin Cabs

This cabinet is sold as a PA speaker.

However, I was considering a similar setup with 1 or 2 1584s. These are supposed to be great PA speakers. I think the 2 eights would really help the upper mid frequecies. Also, you can use the builtin crossovers or bi-amp these cabinets. The frequency response published seem very good for a bass cabinet. The reason I liked the idea of 2 1584s is because I would use them as PA speakers sometimes.

This is a similar configuration to the Carvin RL6815 but it allows you to use your own amp. Also, I think the RL6815 requires you to bi-amp.

 

I wont recommend that cabinet for Bass Guitar aplications.
Piezo Horns sound awful with Bass guitars frequencies feeded by a Bass Amp.

On the other hand, that isnt the aplication it was designed for and no tone-shaping devices can give you a good sound unless the components fit the aplication.

 

I don't think this would be a problem on this speaker.

Because it is a three-way system the crossover points are 2K and 5.5K. There will be virtually no sound from the bass above 5.5K. If I were going to bi-amp, I would even consider trying frequencies lower than 2K for the crossover frequency for bass guitar to get those eights working a little harder.

It is true that you are buying a horn that you won't get much use from, but if you ever decide to use it for other than bass, those frequencies will be covered.

I still like the idea. The published specs indicate that it has better low frequency handling than the RL118.

 

I completely disaggree.
Overtones can go high up to 15KHz and more, also slap transient/fret noise/highs get up very very high.

Also, Piezo Dispersion Horns sound afwfull with Bass Guitar.

 

I'm sorta with Luis, in that, most PA cabs just aren't designed for an authoritative bass guitar sound. If it were otherwise, believe me, many others would have found a way to beat "the system" long ago.

Even if you were rolling off all of your lows into that cab, I wouldn't recommend it. We both have an LB75 and from my experience, the 15"s Carvin has Eminence make for them just scream bloody murder when you use the B string. If Carvin has the same thing with their 18", I might be more enthusiastic.

 

Hey Rick, the RL115 does have the Cast Frame Speaker, I think It could sound a lot better than the one in the cyclops beause of acoustic load and speaker quality.

 

At MikeyD's suggestion, I took off one of the cab handles and looked inside with a flashlight. The frame was epoxy covered, which led me to believe it is cast frame, as you say.

Maybe it is the cab design. It sure farts out when that B string does some work at E or below. I'll be selling the Cyclops cab since I bought a couple of Eden cabs over the weekend. Although, I think the Cyclops' 15" would handle about anything a 4 string could throw at it.

 

I've been corresponding with an engineer/bassist who has done a lot of oscilloscope work with his 5-string bass. He doesn't see any true harmonics above 7 KHz... but he qualifies that with stating that slappers and distortion pedals will push the artificial harmonics up to 20 KHz.

Yep. Piezo el-cheapo tweeters are dreadful.

 

Uhmm Ok.
What Eden Cabs did you buy?
How do they compare against your RL410T and RL118?

 

I tried the4X10HE pro with my ProIV and found a deep bass sound . I prefer the Eden's clean sound. They have a SXT 1000 watts 4X10. To each his own?

 

I'm playing the waiting game, like you did.

I'm keeping the RL1018 for the bigger rooms.

 

Hi, Rick - we've been doing a lot of e-mail back and forth on this, and I wasn't sure what your plans were for your existing Carvin gear.

Given that the Eden speakers you're buying are probably 3-5 dB more sensitive, they might actually be louder than the Carvin stack when you push them with an R600 bridged. I did a crude measurement on my Eden 2x15 (sensitivity claimed to be 103 dB @1w, 1m) and I found it to be around 4+ dB louder than my Carvin 1x18, so it needs only about a third of the power.

We'll be interested to see how your two stacks compare.

To the original poster - yes that Carvin PA cab looks decent. I didn't go for it mainly because of its size and weight. Given its size and configuration, and the frequency response chart in Carvin's catalog, I would not be surprised if the 1588 has much better low end than any of their current line of bass guitar cabinets. That big HF horn does not appear to be piezoelectric - looks like a compression driver. I agree with the point made about very little HF energy from bass guitar signals above about 5 kHz. There is some, but it is very small even in the best case. It might just be a good-sounding cabinet, if you are willing to deal with its bulk.

I don't think the horn is a piezo. I seems to be ported for lower bass than the Carvin bass cabs and even most of the subwoofer cabs. Still looks good to me.

 

The 1588 appears to be using the PS1100 horn. I haven't found any evidence that it uses a piezoelectric driver. My guess is it's a good tweeter for bass applications. I did more thinking on the suitability of the 1588 for bass guitar and, judging from the specs, I'd bet it gives a better overall sound than almost *any* of Carvin's other single cabinets. (While their 1802 subwoofer has stronger bottom, it is not a full-range cabinet.) The 1588 is just kind of bulky; otherwise I'd have seriously considered it before.

That sure wouldn't bring a tear to my eye. The neighbors might be bawling though, since I intended to use the Edens for home and smaller rooms.

Maybe I'll have three cabs for sale.

Thanks for the info about your testing. Great info as always, Mike!!!
