My JBL 373x non dedicated theater build
Over the years, I've had a lot of different speakers in several different rooms. Within the most recent years I've had JTR triple 8s and triple 12s, JBL 3677, Yorkville U215, Elusive 1099, some mini monitors and one off line arrays from GR Research and a few others designs as well. Not so recent I've had the Carver Amazings and Legacy Focus. I liked all of them for their individual strengths and I've heard a lot of great attributes but rarely all in one speaker. After experiencing my own speakers as well as having been to a couple of friend's houses with some nice set ups I've come to like certain traits. I like a BIG sound, large sweet spot, great vocal clarity, extreme mid bass, able to crank loud but not be harsh, sound good at low listening levels...Oh and also able to play something delicate and do it justice then play double duty and represent IMAX style . I'm not asking much right lol?
I used to have a dedicated man cave and scary dynamics was easy. Currently I'm in a house with an open floor plan with an L shaped living room with lots of windows and compromises. I have been able to achieve some good sound but great takes a lot more work especially in trying to keep it décor friendly for my lady.
My current L & R set up consists of the horn section from the JBL 3731/3732 with passive crossover in between the mid and tweet. Right now the tops are being driven off my Denon x4000 with no high pass then using the main pre outs to an active crossover with the bottoms getting 1000 to 1350 (depending on impedance) from a crown xli 3500. The tops have remained a constant but the bottoms have been changed a lot. In the man cave I had some sealed JBL 2242s and all was good...not anymore. In my current place I tried some sealed AE PB18h+ and again just couldn't get I was looking for. I then tried the AE 18s ported at 38hz tune thanks to LTD02 who has helped me a lot! That was better but with the subs turned off, still didn't have the impact I thought it should for having an 18 in that role. The combo that I finally decided on was dual ported AE TD15x tuned to 45hz per speaker. That combo per measurements with Omni mic and my ears is the best.
With the way things were set up, I didn't expect to sound good but to my ears it did and it made me want to take it to the next level. Now I've got some Crown DSI 1000s that just arrived last week that have actual presets for JBL cinema speakers. I'm going to run that for the tops and still keep the XLI 3500 for the bottoms but using a dcx 2496 vs the DBX 223xl. I'll have a lot more control and flexibility as I do have some issue in the crossover region between the mid bass and the horn. LTD02 said this was a result of active bottom and passive top.
For center I have the exact same components as the L and R but in the interest of having some more space to put gear, the though has crossed my mind to get a JBL 4722. I had a 4622 in position there which measured well but with the 4722, I'd still be timbre matched across all three as they use the same tweet. Still undecided on that one.
For LFE I've got two 15 hz tuned ported UXL 18s up front with another two nearfield. I also have another two soon to come from the UXL group buy for a total of 6. To pick up any slack in the ULF region, I've got 4 Crowson transducers driven by the crowson D500 amp. All subs will driven by FP10k and FP14K. Still have to work out the final configuration. My thoughts are to keep the two UXL up front the exact same. Then build 4 mini marty 15hz tune for nearfield. Then with the freed up AE 18s, place those up front on top of the UXL cabs to help clean up the 60 to 90hz region a bit. I just want that clean sound from the L and R to transition all the way down.
There will be more to come but for now at least some pics from where I began to where I'm at currently. Not pictured is the 120" AT screen that most of this is hidden behind...soon.
