JBL SR4735A vs JBL TR225

Friends of speakers plans.com thank you very much for your support

But I wanted to tell you that here in Venezuela we have many problems with electricity, the internet and telephones. After I placed the publication to consult about the TR225 or the SR4735 I was two or three days without internet service and I could not see their recommendations on time.

In short to summarize I buy 6 boxes TR225 at a very good price the 6 boxes 120 $ below the price of the 4 SR4735A. When I made the decision I thought that no matter how bad they were, there were 12 Midbass units of 15 inches to 8 ohms, instead of 4 units of 15 inches to 4 ohms. I also did not think they were so bad because I have friends who have the JBL JRX125 who use the same M115-8 components and have behaved quite well, the only complaint of them is in relation to the 2412h highs that are very delicate and burn with certain ease.

Finally upon receiving the shipment of the boxes I was able to confirm that the material from which they are built is very bad. There are 4 of them that have very crumbled the wooden top of the floor, the material is falling apart and there are 3 that the diffusers are not adjusted, but they are not fixed with screws it seems that they were put under pressure in the box in the process of building. So I decided to build some new acoustic boxes for these components and I wanted to hear your opinion about it.

I find myself hesitant between building 6 equal boxes, dual 15 inch using two 2412 drivers in each box instead of just one and keeping their crossovers, or instead making a new three-way boxes project using also 12 lower media that I have 12 inches, 8 of them are FANE model Colossus 12MB and 4 of them are BOHEM model PB250, that are similar in the chassis to the FANE and also have 3-inch coil as the FANE but are of lower power and the frequency range is difference and the sensitivity also It is less. I also have 6 additional JBL 2412H drivers in addition to the ones that brought the TR225.

And I also have 8 Eminence PSD2002 Drivers and also 8 Lanzar Pro D220S
It would count in total with the following components:

MID-BASS Components
12 JBL M115-8 (15 Inch 225 Watts RMS 98Db Sensitivity Freq 45 Hz-3.9 kHz, VC 2.5)
08 FANE Colossus 12MB (12 Inch 450 Watts RMS 98Db Sensitivity Freq 40 Hz-3.5 kHz VC 3.0)
04 BOHEM PB250 (12 Inch 250 Watts RMS 96Db Sensitivity Freq 49 Hz-2.9 kHz VC 3.0)

DRIVERS Components
12 JBL 2412h (1 inch VC  1 inch,  50 W  RMS, Freq 2.5 kHz - 18 kHz, Sensitivity 104 DB)
08 Eminence PSD2002 (1 inch, VC 2 inch, 80 W  RMS, Freq 1.2 kHz - 20 kHz, Sensitivity 106.1 DB)
08 Lanzar Pro D220S (1 inch VC 1.75 inch, , 85 W  RMS, Freq 1.2 kHz - 20 kHz, Sensitivity 108 DB)

I use a two loudspeaker process ALTO MAXIDRIVE 3.4 and one SPYN DSMS28, I also have 10 subs Type RCF ESW1018, of these 4 have FANE Colosuss 18XB and 6 have EAW model LC1816 which is the same Eighten Sound 18lw1400 and two type TURBO SOUND TSW118 with SoundBarrier SBP18110

In amplifiers I use the following:
02 JBL MPX1200 (sometimes I use them for bass or in others for low media)
02 QSC ISA750 (I use them with the JBL TR225 in full range with their crossover 2 boxes per side, I have also used them to move Highs )
02 SoundBarrier PCS3400 (I use them to move 4 ESW1018 with each amplifier)
02 American Audio V2001 (I use it for drivers or sometime for monitoring)
01 Crown XS900 (I use it in bridge mode to move two ESW1018)

I usually attend events such as weddings, 15 years and sporadically sound for music groups or bands.

So I was thinking of two options:

A) Build 6 Boxes using the same components of the TR225 in new boxes with the necessary liters and instead of using a single driver use two 2412H placed in series to reaches 16 Ohmns and can have more protection. I can use these boxes full range in groups of 4 with a single amplifier QSC ISA750. And build additional 6 Boxes with low media of 12 inches each with two 12 midbass and two drivers. Or build 8 boxes only with the FANE media and two drivers each type array.

B) Build 12 boxes using one MidBass 15 JBL and one MidBass 12 and two drivers for each box and can stack them in 6 per side type line array.

My idea would be that if at some point I have to cover a large outdoor event, something like 4,000 or 8,000 people, I should have the capacity to attend it, and at the same time I can also use these speakers in the simplest events. Something that is compact that is not so big and that does the job.

Here I show you some designs to listen to your opinions


A thousand thanks again friends
