It’s been a while since I’ve posted in the thread and wanted to provide an update on my dual TV42s (serial numbers 10 and 11) along with a couple of in-room photos of them.
I continue to be amazed by the sound quality of these subs – they are truly phenomenal, end-game subs for virtually any theater. The sound from them is incredibly clean, precise, and articulate. Whether used for music, movies, or gaming, they are simply incredible with the accuracy of sound and the prodigious amount of intense bass they can produce.
The output of the TV42s are amazing and the limit for most people will likely be their concern for sheetrock screws popping, pictures falling off neighboring walls or precious vases crashing down from shelves. You have been warned – I learned the hard way but fortunately have a loving and understanding wife!!! (Special hint – use Blu-Tack reusable adhesives on things that might move prior to cranking up your subs to prevent rattles and things crashing).
My room is roughly 1,700 cubic feet (16’ wide x 12’ deep x 9’ high) – a mid-size bedroom converted for home theater use on a lower level concrete floor. While many would say I’m nuts for having a pair of these in this relatively small room, I’m thrilled that I got the TV42s after a long progression of subs over the years (various Velodynes, several SVS subs including PB12-Plus/2 and dual PB13 Ultras, JTR Orbit Shifter LFU, dual SVS S3600s). For me it was the right choice in that I no longer wonder “What if?” or have other sub envy along with the knowledge that I have the best sounding subs I could possibly buy for my room. There are gobs of untapped power but that’s great for proper EQing, using BassEQ for movies or simply frightening guests during demos.
One of the things I really hoped for during this upgrade from dual S3600s to TV42s was a spectacular increase in tactile response in my room. There is a big / huge difference, but for me, it was still less than I was hoping for. Don’t get me wrong these things will pound you and make your arm hair stand on end but I must be a fool looking for / hoping for even more. I already use Crowsons but am unfortunately on a concrete floor. I think there is some strange phenomena with small rooms on concrete as the people sitting on the sofa in the room above my theater feel and hear the whole house shaking and pop cans / glass rattling on the end tables next to them. If you are in a small room with a concrete floor, the best solution is to get the best subs you can afford and build a BOSS platform if you’re looking for tactile response and/or add Crowsons to the mix. I think
described this being the optimum solution for his setup as well. While I wish I had more tactile response, I think it’s a personal thing as I think most “normal” people would be overwhelmed with the pressurization and tactile response in the room.
With some of the posts related to hum, I’ve attached a couple of sweeps of the noise floor of my two TV42 subs as it relates to some of the apparent variability in the SpeakerPower plate amps that are used. I’ve posted a graph with the base noise floor in my room with nothing running (the spike at 120 Hz is from a freezer in my mechanical room) along with the sound levels in my room with both my quiet and noisy TV42 amps individually measured. These levels were recorded in the daytime with related exterior noise and the whole family home due to COVID restrictions. I attached one graph from my main listening position which is 9 feet from the noisy sub and 7 feet from the quiet sub. I also posted both subs as measured at 2 feet from the face of the grill which makes the difference between them clearer.
I know Tom is working extremely hard to find a solution and I saw a recent post that SpeakerPower is working to resolve the problem with variability in some of the amps. I trust in Tom and know that he’ll find a solution for this and make it right with all TV42 owners who happen to have a humming amp that isn’t related to a grounding issue. Keep in mind there have been an on-going issues with this particular version of the SpeakerPower plate amp used that you’ll also find with other products using this amp. I believe this was the same model SpeakerPower amp in the JTR Orbit Shifter LFU I once owned where the hum seemed markedly louder due to the horn design.
Hopefully, they will solve the problem soon as the TV42 is an absolutely incredible sub to hear and I feel extremely fortunate to have a pair of these BEASTS!
