Which one is the best pro" box" that could be moved into your home for hi-fi use?

[martin_wu99]

My choice is 4628B,because of its drives(E145-8,2118,2404 are all hi-fi drivers),and Zilch had mentioned it before.
Pos has recommended SRX738.
what's your opinion?:applaud:

The Cabaret serie was designed to play loud (for its size) and be easily moveable. I don't know how hif-fi this one sounds, but I'd say from the (small) size of the cabinet that the bass must be boomy. That is fine for playing loud, but not for home hifi. You may want to double the cabinet's size.

Thanks for your input.
I like these Cabaret series,i have 4698B also,Mark Gander designed them.because their basses are bypass,so they sound dusky and sweet.

4628b crossover

The AE series work well. I've used the AM6215/95 as a center channel in a previous config.

Thank you for your recommendition.
I think many JBL pro boxes can be used in HT system.
I want to konw if there are any JBL pro boxes that can be used as HIFI gear in a house.:confused:

I just listened to the JBL 4628's that I talked my 2nd ex into buying years ago. Oh yeah, they'll get plenty loud, but there's not a lot of bass, that's for sure. I believe these are 'reinforcement' speakers and they were specifically designed for keyboards.

You might think that those 15" woofers will deliver some slammin' bass, no, they will not. Zilch modified one of three 4628's (correct me if I'm wrong), by using a plumbing plug on one of them to boost the bass capabilities.

I peruse CL every day and I see tons of pro gear for sale, the SR series and the JRX series are popular. I'd be real reluctant to own these based on my Cabaret experience.

Finally, let's make it clear what "Pro" means. It can be one of two things in my opinion. It's either PA use or Studio Use. If you you're looking for a "Pro" system you can use at home, take a look at the Studio Monitors, like the 43xx series (I own the 4315's still).

Thanks for sharing your experience of pro box.
you said exactly right:4628B lacks some low extension and bass volume is not enough, but the MF and the HF is beautiful,that's why i love them,it's a bassguitar and keyboard reinforcement musical box!
The key question is how to improve them to be more suitable for hifi purpose,they are some options below:
1.replace 2404 with 2407(pos motioned).
2.replace 2118 with 2123(someone here have tried)
3.add 2425(like 55000)
4.just throw them away:banghead:
what's your option?:confused:
BTW,42,43,44,LSR are very popular in home hifi,i here just mean PA box:D

Personally, I'll let somebody else cover those options, as that's exceeds my personal knowledge base, but if it was my set, I'd buy a pair of nice powered subwoofers, like the Velodyne HGS-12's, which would easily hid behind those huge boxes and you'd be good to go! You can set the crossover point and volume easily on the subs to get the sound you want and I'd bet that it would sound excellent!

Those 4628's are truly very powerful speakers on the highs and mids, they just need some help with the bottom.

I bought a DCX2496 for 4628B, but i have no time to adjust the crossover points of 4628B.
To simplification,myabe somebody expert here can redesign the passive crossover for 4628B:applaud:

[Regis]

In my opinion, you're going too far. You want to go with a Behringer DCX2496 speaker management system, redo the crossovers, replace the woofers in the 4628's etc, etc. Just play the 4628's as is! Then adjust the subwoofer crossover and volume until it pleases you! If you apply too much volume on the sub or too much low frequency, you will hear the midrange being smothered or suppressed and then you turn down the subwoofer.

You can do this by ear and what you want is for the subwoofer to pick up, where the 4628's drop off, it's that easy! No need to buy a bunch of equipment, rebuild custom crossovers, replace woofers in the 4628, etc, etc, because you might as well just get another pair of speakers. Just set it up, adjust it out and play!

[Lee in Montreal]

In my opinion you both go too far. Run the 4628 as is, and add two active subs with an integrated crossover that can be set to around 40Hz. Set this crossover by ear depending on the locations.

Transforming PA box into hifi cabinet is a big fun and challenging work for a real JBL fans,and also is a economic way to get high quality sound.
After fine adjusting,I'm sure that 4628b can beat many 15' hif cabinets:D

Who will go so far as to buy two expensive active subs?:p
but it's acceptable to adding two subs for hifi if you need more low end:D

I did! I was running two Velodyne HGS-12's (no external crossover) with my 4315's, as described. My initial problem was there wasn't a lot of bass from the 4315's, but once I changed my preamp from a modern digital unit, to a vintage Marantz, the bass came back and I sold the Velo's!

But it did work well, without having to modify the collectable 4315's or running an external crossover. Maybe Lee's solution is the deal, but I don't know enough about active subs or integrated crossovers to say if that works or not. It just very well may do the trick, but I think what I was running was simpler. Maybe less accurate, as I set the crossover point and volume on each sub by ear, but it sure sounded good to me!

I would take a serious look at the new STX 825 or STX 835 when they come out. Their spec sheets look quite flat and reasonably extended. I've heard the SRX 725 at the local Guitar Center and it was quite musical. So, I'll assume that the STX models named could be better sounding given their measurements.

Back to the 4628B
I noticed that 2402,2403,2404 and 2405 are defined as UHF,so they are seldom used with mid cone drivers ,but there are exceptions,such as in 4628B,4698B,4612B,4730A.
The crossover point of 4628B,4698B,4612B is 3kHz.
The crossover point of 4730A is 3.5kHz.
The 2404s are all used with 2118s,so 2404 with 2118 is a COMBO:bouncy:
Similar examples in JBL household products are L65 and L220
L65 LE5-6+077 crossover point is 6.5kHz.
L220 LE5-9+076 crossover point is 5KHz.
So in my opinon,if you want a PA box to be used in your house and want them sound smoothly like silk,softly like cashmere,just as good as JBL monitors,then they must possess some characteristics below:
1.Have a UHF unit, so the HF could be delicate.
2.Three way system with middle cone driver,for near field use,not for long distance throw,so the sound will be warm and soft.
4628B is just the case.:D
Any comments,PLS

Martin...

You're right...the 4628B system is a killer multi-purpose speaker system....great platform. If you want to improve the low end response, you can build a new box of similar volume and add a passive radiator on the rear rather that a tuned port. The PR will allow you to change the tuning by mass loading. The E145 is a tremendously clean and thunderous/punchy driver. If it's good enough for the Paragon, it's good enough for hi-fi. It's basically a refined 150-4.

Another weak point for hi-fi definition is the 4628B crossover. It's as basic as it gets. Simply hi pass filters on the 2118 and 2404 while the E145 runs full range. The system shines best when stock when it's playing fairly loud....because that's what it was designed for.

Have fun and good luck with your project.

Thank you very much for your positive input and constructive advice.
It's a creative idea to add a PR on the box,then what's model of the PR?
I know that the E145 in 4628B has no low pass filter,i have a idea of replacing the crossover with 4730A's.Does it work?
