Dalam menentukan posisi speaker maka perlu diketahui terlebih dahulu tingkat kebisingan dari area / ruangan yang akan di pasang speaker atau biasa di kenal dengan istilah Ambient noise level ( tingkat kebisingan lingkungan ) . Pemahaman tingkat kebisingan sangat diperlukan agar suara / informasi yang akan disampaikan bisa sampai ke pendengar dengan baik.
Untuk memperoleh Noise Level / tingkat kebisingan dapat mempergunakan Noise meter, dimana dengan alat tersebut akan dengan mudah kita dapat mengetahui seberapa besar noise level ruangan yang akan kita pasang speaker.
Tetapi bagi yang tidak memiliki alat ukur noise meter, bisa menggunakan referensi hasil pengukuran berikut ini :

75 - 85 dB ---> Percakapan biasa
65 - 85 dB ---> perkantoran, rumah sakit, hotel, bank
80 - 90 dB ---> printing mechine, perkantoran yang
berisik, sekolah
> 90 dB ---> stasiun kereta api, pasar, pabrik, dll

Dengan mengetahui besarnya tingkat noise ruangan yang akan kita pasang speaker maka kita bisa memperkirakan berapa besar SPL yang sesuai dan speaker apa yang sesuai dengan kebutuhan tersebut.

saya tambahkan lagi !!! bahwa SPL sebuah speaker tidak berbanding lurus dengan Jumlah speaker. Pemahaman saya begini :
Mis 1 buah speaker full range 15in 125w 121db bila ditambahkan dengan watt yg sama Mis 250w itu bukan berarti menjadi
242 db ttp hanya menambah 3db maka menjadi 121+3=124 db dst.Catatan bila di yakini bahwa speaker bersangkutan benar2
sama.

SPL setahu saya dapat ditentukan dengan alat ukur. ada free dan ada yang berbayar. Biasa pada HP berbasis android itu
sdh lebih bisa.nama soft warenya ada Sound meter atau SPL Meter. Ttp sebenarx klu speaker2 yang bagus rata2 mempunyai
spl di atas 100 db.
